Farm health technician specialisation

Prevent, monitor, alert and document, with the veterinarian of your area

Introduction

On a poultry farm with several houses, someone has to be the guardian of health: the one who stops disease from entering and circulating, who detects it before it can be seen, who alerts at the right moment and who writes down everything that happened for the veterinarian, the owner and the next flock. That is the farm health technician. The "Farm health technician" specialisation of the NEXTEKCI School (Agnibilékrou, Côte d'Ivoire) extends level 9 of the curriculum, devoted to the health of one house, and changes scale: ten lessons follow a model farm of three open-sided houses of 8 m by 30 m, 1,200 broilers each at 5 per m² in hot weather, with different ages, staff, deliveries, pick-ups and a veterinarian of the area who counts on the technician. You learn the exact role of the technician and the line with the veterinarian, the health plan written together with him (zones, flows, visit calendar, responsibilities), daily biosecurity with its figures (anteroom, colour-coded clothing, seven renewed footbaths, visitors, vehicles, rodents, flies, carcasses), the monitoring of three houses with house and farm thresholds and curves, the observation and description of a flock with exact words, the fourteen-heading report, samples and the reading of a result with the veterinarian, the management of an alert that protects the healthy houses, the sanitary break at farm scale and the 25-point health audit scored out of 50. Each notion is explained simply, with a worked, numbered example and the field gesture. One rule runs through the ten lessons: we describe, prevent, alert, document; we do not diagnose, we never treat alone. Care, analyses and the vaccination programme are those of the veterinarian of the area. Open from free registration, after or alongside the 15 levels.

By the end of this specialisation, you will be able to

✓Hold the role of health technician on a farm with several houses and write, with the veterinarian of the area, the health plan that governs it
✓Keep biosecurity alive every day and monitor all the houses with records, numbered alert thresholds and curves
✓Observe, describe, photograph, sample and write a report the veterinarian can use, then read the results with him
✓Manage an alert without contaminating the other houses, plan the sanitary breaks and audit the farm in 25 points with a correction plan

10 lessons · a 5-question quiz after each lesson · an exam (20 questions, 80%) · verifiable specialisation certificate. Specialisation open to every registered student, in any order.

The role of the health technician: prevent, monitor, alert, document (never treat alone)
In level 9 you learned the health of one house: the agents, the thresholds, the observation of a dead bird, the report to the vet. This specialisation changes scale: you become the person responsible for the health of a farm with several houses, different ages, staff, visitors, trucks, and a veterinarian of the area who counts on you. The job comes down to four verbs and one prohibition: prevent, monitor, alert, document, and never treat alone. This first lesson draws the exact line between what you do and what the veterinarian does, then describes your day, your registers and your tools on a model farm of three houses that we will follow through the ten lessons.
What you will learn
✓Define the job of farm health technician and distinguish it from the production technician and the veterinarian
✓Describe the four missions (prevent, monitor, alert, document) with a worked example for each
✓Place the line between the technician and the veterinarian of the area, point by point
✓Organise the day and the week on a three-house farm and keep the six registers of the post
Lesson outline
A job of its own: the guardian of the health of the whole farm
The four verbs of the job
The line with the veterinarian, point by point
The day and the week of the health technician
The six registers and the tools of the post
Common mistake: the technician who knows
Going further
Key points
•The farm health technician keeps the farm closed to germs and detects early; on several houses of different ages, this role must be distinct from production.
•Four verbs with a proof each: prevent (signed biosecurity sheets), monitor (daily sheets and dashboard), alert (time-stamped message), document (six registers).
•The line: the technician describes, isolates, samples on request, applies and notes; the veterinarian of the area diagnoses, prescribes, decides the vaccination programme and informs the veterinary services.
•Sanitary forward flow: from the youngest to the oldest, from the healthy to the suspect, footbath between each house; pure monitoring of about 2 h 20 per day for three houses of 1,200 birds.
•Always three lines: Observed, Orientation, Conclusion: none, that is for the veterinarian.

The farm health plan, written with the veterinarian: zones, flows, calendar, responsibilities
The level 9 biosecurity plan protected one house. The farm health plan does more: it organises the health of the whole operation, with its three houses of different ages, its staff, deliveries and pick-ups, and it is written by two hands, those of the health technician and those of the veterinarian of the area. It is the only document in which the veterinarian says, in advance and in writing, what he expects from the farm, how often he comes, and who does what when a figure goes wrong. This lesson teaches you to build it chapter by chapter, on the three-house farm, and to keep it alive instead of letting it sleep in a drawer.
What you will learn
✓Distinguish the farm health plan from the biosecurity plan of one house and explain why it is written with the veterinarian
✓Draw the zoning and the flows of a farm with three houses of different ages
✓Build the calendar of veterinary visits and the table of responsibilities
✓Write the eight chapters of the plan and organise its revision
Lesson outline
From the biosecurity plan to the farm health plan
Zoning a three-house farm
Flows at farm scale
The calendar of veterinary visits
Who does what: the table of responsibilities
Writing the eight chapters and keeping the plan alive
Going further
Key points
•The farm health plan includes the biosecurity plan and adds age management, the veterinarian’s calendar, the prevention programme decided by him and the responsibilities; it is co-signed by the veterinarian of the area.
•Three zones, and the green zone divided into one sub-zone per house, each with its boots, colour, equipment and footbaths; houses at least 20 m apart, the youngest upwind, pit 60 m downwind.
•Two flow rules: a clean flow never crosses a dirty flow; nothing goes from an older house to a younger one.
•Routine visits at five moments of each flock; with three staggered flocks, about one visit every two weeks, each prepared with a list per house.
•Eight chapters, a responsible-checker-decider table, the technician’s right to call written down, and three appointments to keep the plan alive: signed reading, Saturday audit, dated revision.

Daily biosecurity: anteroom, clothing, footbaths, visitors, vehicles, rodents, flies
The health plan says what must be done; daily biosecurity is doing it every day, including Sunday, including when the owner is in a hurry and the buyer is waiting. On a three-house farm, this means dozens of repeated gestures: brushing, dipping, changing boots, signing a register, counting flies, checking a bait station, carrying a closed bucket. Each of these gestures has a figure behind it: a volume, a frequency, a distance, a delay. This lesson gives those figures, calculates them on the farm we are following, and gives you the daily checklist of the health technician.
What you will learn
✓Organise the anteroom, the colour-coded clothing and the boot circuit on a three-house farm
✓Size and renew the footbaths with a volume calculation and a calendar
✓Manage visitors, vehicles, rodents, flies and carcasses with numbered rules
✓Keep the daily and weekly biosecurity checklist
Lesson outline
The anteroom and the clothing: the border crossed twenty times a day
Footbaths: volume, renewal, and what makes them useless
Visitors and vehicles: the gate decides
Rodents and flies: count in order to act
Carcasses: twice a day, a closed bucket, 60 metres
Going further
Key points
•One single anteroom with bench and soap, three sets of colour-coded clothing (H3 blue, H2 green, H1 red) and one mini-anteroom per sub-zone; hands washed for twenty seconds at every entry and exit; the phone does not enter.
•Seven footbaths of 10 to 12 litres, brush and bucket of water in front, ten seconds flat, lid, renewal every two days at most (210 litres per week on the farm), each renewal noted.
•Visitors: register, 48 hours without poultry, clothing provided, accompanied; outside vehicles stopped at the red boundary; buyer on the loading area with farm crates.
•Rodents: one bait station every 10 to 15 m (22 on the farm), checked on Monday, action above 20 % eaten; flies: one sticky card per house, action above 100 per week, alert above 300.
•Carcasses: morning and evening, closed bucket per sub-zone, counted, carried after the round to the pit 60 m away, never in front of a younger house; hands washed.

Monitoring: daily records, alert thresholds, curves, and the moment to call
In level 9 you learned the thresholds of one house: mortality, water, feed, weight. On a three-house farm, monitoring changes in nature: the same figures must be recorded three times, brought back to a common base to be compared, drawn as curves to see the shape and not only the figure of the day, and above all you must recognise the moment when a problem stops being that of one house and becomes that of the farm. This lesson builds the farm health dashboard, sets the thresholds per house and per farm, teaches you to draw and read a curve on squared paper, and says exactly who calls whom, within how long.
What you will learn
✓Organise the daily records of three houses and bring them to a common base (per 1,000 birds)
✓Apply the alert thresholds per house and define the farm thresholds
✓Draw and read the mortality, water and weight curves on paper
✓Trigger the alert at the right level, within the right time, with the right message
Lesson outline
Recording three houses: the same measure, the same time, the same base
Thresholds per house, recalled; farm thresholds, new
Drawing a curve: seeing the shape before the figure
The moment to call: the farm green-orange-red plan
Going further
Key points
•Record the same figures at the same time in the three houses and bring them to a common base: per 1,000 birds, variation from the day before, comparison with the same day of age of the previous flock.
•Thresholds per house (level 9): mortality 0.3 % orange, 0.5 % two days or 1 % red; water −10 to −15 % orange, −20 % red; feed −10 / −20 %; weight −5 / −10 %, uniformity < 70 %.
•Farm thresholds: two houses in orange the same day, one red and one orange within 48 hours, water falling everywhere, same sign in two houses = farm red, call the same day, common causes checked, samples set aside.
•Three curves per house (cumulative mortality, water per 1,000, weekly weight) with the dotted target and the events line; read the slope and the widening gap, not only the point.
•Posted green-orange-red-farm red plan with the times (2 hours in orange, the same day in red, within the hour in farm red and for nervous signs); twelve-line standard message from the dashboard.

Observe, describe, photograph: preparing a useful report for the veterinarian
The veterinarian of the area receives dozens of messages every week saying "they are dying" or "they look strange". He almost never receives any saying "38 ruffled out of 200 observed in the western third, orange droppings with mucus 9 out of 20, rattles in 6 out of 50 listened to, pale comb 3 out of 3". The second message saves him a day and saves you birds. In level 9 you learned to examine a dead bird and fill in an observation sheet. This lesson trains the farm health technician to observe a live flock with method, to speak the exact language the veterinarian understands, to photograph so that the image is useful, and to write the fourteen-heading report at the scale of a three-house farm.
What you will learn
✓Observe a live flock with a method that gives numbers: zones, sample, counting
✓Describe with the exact vocabulary of the health technician, without concluding
✓Photograph and film according to a named protocol, at farm scale
✓Write the fourteen-heading report for one or several houses and prepare the veterinarian’s visit
Lesson outline
Observing a live flock: the method that gives numbers
Describing: the language of the health technician
Photographing and filming: the farm protocol
The fourteen-heading report at farm scale
Preparing the veterinarian’s visit
Going further
Key points
•Observe = six zones of 40 m² per house, 30 to 35 birds per zone (about 200), white card for 20 minutes in an affected zone and a normal one, five birds caught; every sign is counted, located, dated.
•Describe = exact words without judgement or diagnosis (ruffled, open beak, orange droppings with mucus, pale comb); never the words that conclude (diarrhoea, coccidiosis, bronchitis); Observed, Orientation, Conclusion: none.
•Photograph = the six rules of level 9 plus a file name house-day-date-series, an identical series per affected house, three context photos; the images go after the report.
•The fourteen-heading report describes the whole farm in heading 2, repeats headings 3 to 10 per affected house, mentions the healthy houses in one line, and asks questions in heading 14.
•Prepare the visit: registers and curves out, fresh birds in the cooler and sick birds isolated, washable table in the shade, labelled samples, clothing at the anteroom, order of visit with the suspect last, owner present.

Samples and analyses: what, when, how to send, and reading a result with the veterinarian
A well-taken sample is the only thing that allows the veterinarian to move from a hypothesis to a certainty: what his eyes cannot see, the laboratory finds, provided the sample is the right one, taken at the right time, in the right container, kept at the right temperature, arrived within the right time, and labelled without error. A badly taken sample costs the price of the analysis, three days of waiting, and a false result that misleads. This lesson teaches the health technician what he may sample when the veterinarian asks him to, how to pack and send it, and how to read the result afterwards with the veterinarian, never interpreting it alone.
What you will learn
✓Distinguish the samples the technician takes at the veterinarian’s request from those that remain the veterinarian’s
✓Take, pack, label and keep a sample of droppings, litter, water, feed and carcasses
✓Organise the dispatch to the laboratory within the cold chain and the time limits
✓Read the structure of an analysis result with the veterinarian, without interpreting alone
Lesson outline
What the technician samples, what the veterinarian samples
Taking and packing: droppings, litter, feed
Water: two points, a sterile bottle, 24 hours
Sending: the cold chain, the time limit, the dispatch form
Reading a result with the veterinarian, never alone
Going further
Key points
•The veterinarian prescribes the analysis and interprets the result; the technician takes the simple samples he asks for (droppings, litter, water, feed, fresh carcasses, swabs) and never blood or acts on the live animal.
•A representative sample: droppings from ten points mixed (50 g), feed from three bags (500 g + a reference kept until the end of the flock), water at the tower and at the end of line (500 mL, sterile bottle, after 2 to 3 minutes of flow).
•Label with a marker on the container: farm, house, age, date, time, nature, sampler, veterinarian; cooler 4 to 8 °C, never frozen; water and droppings at the laboratory within 24 hours, litter and feed within 48 hours.
•The dispatch form copies the veterinarian’s prescription; the health register keeps what, when, by whom, left and received at what time, result expected.
•Reading a result = checking the identification, the condition of the sample, the method, the figure and its unit, the reference, the comment; passing it to the veterinarian without comment and reading with him; never announcing or deciding alone.

Managing an alert: isolate, protect the other houses, inform, keep the register
In a single house, an alert is a race against the disease. On a three-house farm, it is also a race against contagion: while H2 is sick, 1,194 eight-day-old chicks in H3 and 1,160 almost finished broilers in H1 have nothing, and the whole work of the health technician is to make sure that stays true. This lesson organises the alert at farm scale, hour by hour: isolate within the affected house, reverse the forward flow to protect the others, inform in the right order and within the right times, keep the alert register that will serve the veterinarian, the buyer and the next flock, and know when and how the alert is lifted. With one rule that does not move: nothing in the water, nothing sold, nothing moved without the veterinarian.
What you will learn
✓Trigger a farm alert and carry out the actions of the first hour in order
✓Organise isolation within the affected house and the reversed forward flow to protect the other houses
✓Inform the veterinarian, the owner and, through the veterinarian, the veterinary services if the disease is notifiable
✓Keep the alert register and conduct the lifting of the alert
Lesson outline
What an alert is, and what it changes on the farm
The first hour: ten actions in order
The reversed forward flow: protecting the healthy houses
Informing: who, in what order, within how long
The alert register and the lifting of the alert
Going further
Key points
•An alert is a written status (start, person responsible, end) that replaces the ordinary rules with strict rules for everyone: suspect house last, daily footbaths, no visitor except the veterinarian, no sale or movement, nothing in the water without a prescription.
•First hour, ten actions in order: declare, call the veterinarian (5 min, without the owner’s agreement), inform the owner (10 min), lock the flows, isolate (12 m² pen for the 14 most affected birds), correct what is allowed, observe and photograph, check the healthy houses, write the fourteen headings, prepare the visit.
•Reversed forward flow: nothing leaves the suspect house, nobody goes back from it to a healthy one the same day, no bird moved or sold; half of the alert time is spent watching the healthy houses.
•Inform in order: veterinarian, owner, team, then buyer and supplier through the owner; notifiable disease = the veterinarian informs the veterinary services, the technician blocks all movement and applies.
•Alert register: trigger, calls, measures, observations, samples, veterinarian’s decisions, daily follow-up, lifting, revision; the lifting is a written decision of the veterinarian (generally three days below 0.3 %, water and feed back, other houses within the norm).

Cleaning, disinfection, sanitary break and the 25-point farm health audit
Level 9 taught you the science of cleaning and disinfection: organic matter first, the families of disinfectants, contact time, the order of the fifteen steps. The farm health technician inherits all of that and adds two things that only a farm with several houses requires: organising the sanitary breaks of three staggered houses without a house under cleaning contaminating a house in production, and checking, through a numbered audit, that the whole farm holds, not only the house that has just been washed. This lesson gives the schedule of the breaks at farm scale, the check before placement, and the 25-point health audit grid, scored out of 50, which you will apply to your own farm in the next lesson.
What you will learn
✓Plan the cleaning, disinfection and sanitary break of three staggered houses without contaminating the houses in production
✓Set and respect the length of the sanitary break validated by the veterinarian and check the house before placement
✓Apply the 25-point health audit grid and calculate the farm score
✓Read the score, spot the weak points and prepare the correction plan
Lesson outline
The sanitary break at farm scale
The check before placement
The health audit: why a score
Scoring, calculating, reading the score
Going further
Key points
•On several houses, the sanitary break is a risky worksite: litter and washing water far from the full houses, separate workers, never on the day of a placement; 63-day cycle (42 of flock, 7 of worksite, 14 of dry break minimum, 21 on the farm); about 17 worksites per year for three houses.
•The length of the break is set by the veterinarian (benchmark: 14 days minimum after disinfection, house dry, longer after an alert) and is decided before ordering the chicks.
•Check at D-3 with the hand: surfaces to the finger, water line connector dismantled (biofilm), dryness, mesh, equipment, real length, documents; a house that fails does not receive chicks.
•Quarterly health audit: 25 points in five chapters (entrances and zones, houses and surroundings, water and feed, animals and monitoring, registers and documents), scored 0, 1 or 2, total out of 50; write what was seen, not "correct".
•Reading: 45-50 under control, 35-44 correct with weaknesses, 25-34 vulnerable, under 25 exposed; the zeros are corrected first; an audit without a correction plan is the list of what is going to happen.

Field exercise: carry out the health audit of your farm and write the correction plan
Eight lessons of rules, figures and registers are worth nothing until they have been laid on your own ground. This exercise has you carry out, in half a day, the health audit of your farm with the 25-point grid of lesson 8, calculate your score out of 50, read it chapter by chapter, then write the correction plan you will present to your owner and your veterinarian of the area. There is no good score to reach to pass the exercise: success is a grid filled in honestly, a "seen" line for every point, and a correction plan with names, dates and proofs. The one-house farm does the same exercise as the three-house farm: the grid adapts, honesty does not.
What you will learn
✓Prepare and carry out the 25-point health audit of your own farm, in half a day
✓Fill in the audit sheet with a score and a written observation for each point
✓Calculate and read the overall and per-chapter score, and draw up the list of zeros
✓Write the correction plan and organise the re-audit
Lesson outline
Before starting: the equipment and the state of mind
Step 1: walk the farm in the order of the grid
Step 2: the audit sheet to fill in
Step 3: calculate and read the result
Step 4: write the correction plan
Step 5: the re-audit and what follows
Going further
Key points
•The audit is done on an ordinary day, without warning, in two to three hours, in the order of the grid (gate → houses → water and feed → animals → registers) and in the order of age of the houses; the auditor passes through the anteroom like everyone else and fixes nothing during the audit.
•For each point: a gesture (hand, finger, tape measure, register open and lines counted), a score 0/1/2, a numbered "seen" line, a photo if 0 or 1; the proof is a trace checkable by someone else, not a memory.
•Score out of 50 and per chapter out of 10; list of zeros; traps: chapter at zero despite a correct score (especially water), very high score the first time, low score that is only the photo of a starting point.
•Correction plan: ten lines at most, all the zeros first, precise gesture, person responsible, deadline, expected proof, verification date; presented to the owner, passed to the veterinarian, posted with the date of the re-audit.
•Re-audit at six weeks (score < 35) or three months; full grid; honest progress of 5 to 10 points per quarter; the audit follow-up table and the six registers are what is shown to the buyer, the slaughterhouse and the bank.

Case study: a week as health technician on a three-house farm
Nine lessons have cut the job into pieces: the role, the plan, biosecurity, monitoring, observation, samples, the alert, the break and the audit. A real week mixes them all, out of order, with an owner on the phone, a buyer waiting, a veterinarian two hours' drive away and twelve-day-old chicks that give no warning. This case study follows Aya, health technician of the three-house farm near Agnibilékrou, from Monday 6:45 to Sunday evening: each day, what she does, what she sees, what she decides, what she refuses, and what it costs or saves. At the end, as always, what should have been done before. It is the exam of the specialisation: knowing where you would have acted differently.
What you will learn
✓Run through a full week as health technician on a farm with three houses of different ages
✓Recognise, day after day, the clues that announce an alert and the exact moment the threshold is crossed
✓Apply in the right order the rules of the nine lessons: visit, monitoring, report, sample, alert, information, register
✓Identify what should have been done before, and what the technician did well
Lesson outline
Monday: the starting situation
Tuesday: the routine visit
Wednesday: the orange of H3
Thursday: the red, the alert, the veterinarian
Friday and Saturday: holding the alert and protecting H1
Sunday: the review, and what should have been done before
Going further
Key points
•A health technician’s week mixes everything: routine, veterinarian’s visit, an orange that corrects itself (H1 Monday), an orange that becomes red (H3 Wednesday-Thursday), alert, samples, result, pick-up, break worksite; the order of age and the suspect house last hold all week.
•An orange is not an alert, it is a re-check with a written threshold for the next day; two oranges in the same house rising two days in a row with counted signs justify the call the same evening.
•During an alert: call within 5 minutes, owner within 10, flows locked, healthy houses visited first, isolation, samples requested by the veterinarian, fourteen-heading report with the sale question in heading 14; the veterinarian decides in writing, with conditions.
•The analysis result goes to the veterinarian without comment and is read with him; the prescription is applied exactly as written, time noted; the lifting waits for three days below 0.3 % and his written decision.
•What should have been done before: correct the audit zeros without waiting for the break, check the lines with the finger at D-3, measure the end-of-line flow in very hot weather, call on the evening of the double orange; none of these corrections costs money.

Frequently asked questions

What is biosecurity on a poultry farm?

Biosecurity is the set of measures that stop a disease agent from entering the farm (external biosecurity), from moving from one house to another (internal biosecurity) and from surviving from one flock to the next. It rests on three pillars: isolation (fence, single gate, distance between houses), control of flows (people, animals, feed, water, equipment, vehicles, carcasses, litter, always from clean to dirty and from the youngest to the oldest) and cleaning-disinfection followed by a sanitary break. In the field, this means an anteroom with a bench and soap, boots and coats per house, renewed footbaths, a visitor register, vehicles stopped at the farm boundary, rodent and fly control and carcass collection twice a day. The NEXTEKCI School (Agnibilékrou) teaches these gestures with their figures; the prevention programme remains that of the veterinarian of the area.

What is the role of a farm health technician, and where does it stop?

The farm health technician prevents (he keeps the biosecurity barriers), monitors (he records every day the dead, water, feed and temperatures of each house and compares them with written thresholds), alerts (he calls the veterinarian as soon as a red threshold is crossed) and documents (he keeps six registers: flock, visitors, biosecurity, health, alerts, sanitary breaks). He stops where the veterinarian of the area begins: he makes no diagnosis, chooses neither product nor quantity, decides on no vaccine, does not interpret an analysis result alone. He describes, isolates, takes the samples he is asked for, applies what is prescribed and notes it. It is this line, learned as a table in the NEXTEKCI School specialisation, that makes him a partner the veterinarian calls back first.

When should you call the veterinarian on a broiler farm?

You call as soon as a red threshold written in advance is crossed, without waiting "until tomorrow to see". The field benchmarks taught by the NEXTEKCI School for broilers in an open-sided house: mortality above 0.5 % per day two days in a row or 1 % in one day, or three days of increase; water down 20 % with no drop in heat, or two days of decrease; feed down 20 %; weight 10 % below target; serious signs (nervous signs, blood in droppings, rattles in many birds, grouped deaths). On a farm with several houses, you also call when two houses cross an orange threshold on the same day: something shared, or something circulating. The veterinarian of the area adjusts these thresholds to your farm; while waiting for him, nothing goes into the water, no bird is sold or moved.

What should you do when mortality rises in a house?

First calculate: dead and culled of the day divided by the number present, multiplied by 100, then compare with the threshold and with the day before. Then act in order: call the veterinarian of the area if the red threshold is crossed; inform the owner with the figures; lock the flows (the affected house is visited last, nothing leaves it, nobody goes back from it to a healthy house); isolate the most affected birds in a pen with their own drinker; correct what is allowed (wet litter removed, fresh water, shade); observe and count the signs in six zones; keep two or three fresh dead birds cool, never frozen; photograph; write the fourteen-heading report; prepare the visit. What you never do: put a product in the water on a hunch, sell or move birds, conclude in place of the veterinarian. The NEXTEKCI School (Agnibilékrou) details this first hour minute by minute.

How long should the sanitary break between two broiler flocks last?

The sanitary break is the period during which the house, emptied, cleaned and disinfected, stays empty, dry and closed before the next flock. Its length is set by the veterinarian of the area in the health plan; the usual benchmark is 14 days minimum after disinfection, house dry, on top of the 5 to 7 days of worksite (litter removal, washing, drying, disinfection). Many well-run farms plan 21 days, and longer after an alert, as the veterinarian decides. A break shortened "because the chicks are arriving" serves no purpose: the length is decided before ordering the chicks. Before placement, the technician checks the house with the hand, not the eye: surfaces to the finger, water line connector dismantled to check for biofilm, dryness, mesh, real length of the break noted in the register. The NEXTEKCI School teaches this check point by point.

How do you take a sample for the laboratory on a poultry farm?

It is the veterinarian of the area who prescribes the analysis and interprets the result; the technician takes the simple samples he asks for. Droppings: about 5 g at ten points spread across the house, droppings less than one hour old, mixed in a clean jar two-thirds full. Water: a sterile bottle, filled three-quarters after two to three minutes of flow, at the source (water tower) and at the end of the furthest line, 500 mL per point. Feed: 500 g taken from three bags of the batch, plus a reference kept on the farm until the end of the flock. Carcasses: two or three dead less than twelve hours old, in a cooler, never frozen. Each container is labelled with a marker (farm, house, age, date, time, nature, sampler, veterinarian), kept at 4 to 8 °C and sent within 24 hours for water and droppings. The result is passed to the veterinarian without comment and read with him, never interpreted alone.

What is a farm health audit and how is it carried out?

A health audit is a methodical inspection of the whole farm with a fixed grid and a score for each point. The NEXTEKCI School grid has 25 points in five chapters: entrances and zones, houses and surroundings, water and feed, animals and monitoring, registers and documents. Each point is scored 0 (absent), 1 (present but incomplete or unproven) or 2 (compliant and proven by a register), for a total out of 50. The audit is done once a quarter, on an ordinary day, without warning the team, in two to three hours, with the gestures (hand on the litter, finger in a water line connector, registers open and lines counted) and a numbered "seen" line for each point. You read the overall score, the score per chapter and above all the list of zeros, then write a correction plan of ten lines at most with person responsible, date and expected proof. An audit without a correction plan is the list of what is going to happen.

Can a health technician treat or vaccinate the chickens himself?

No. The diagnosis, the choice of a product, the quantity, the duration, the waiting period before sale and the vaccination programme are decisions of the veterinarian of the area. The health technician applies exactly what the veterinarian has prescribed in writing, notes the date, the house and what he observes afterwards, and keeps the register of vaccinations done according to the veterinarian's programme (date, age, product and batch number, route, who, reactions). A product put in the water on a hunch, even well-meant, masks the signs, blurs the diagnosis, imposes a waiting period before sale and can make the case worse. The sentence the NEXTEKCI School (Agnibilékrou) has you repeat in every lesson of the specialisation is simple: "Observed, orientation, conclusion: none, that is for the veterinarian." For any question about the health of your poultry, contact the veterinarian of your area.

In conclusion

By the end, you are the health technician every veterinarian would like to find on a farm: accurate, comparable records, thresholds that decide instead of emotion, a numbered, counted report, well-packed samples, an alert that stays in a single house, complete registers and a quarterly audit followed by a correction plan. The exam goes back over the ten lessons with worked calculations and justified decisions; it awards the "Farm health technician" specialisation certificate, issued privately by NEXTEKCI. The NEXTEKCI Academy shows the gestures on video and Maria, the online assistant, answers your questions.
