Level 10 — Technical analysis and management
Calculate the indices, compare with the standard, find the real cause
Cycle 2 — Technician (levels 6 to 10) · at the end of this level: Poultry Technician Certificate
Introduction
Last level of the Technician cycle. A technician is recognised by the way they read figures: daily gain, feed conversion, livability, efficiency index, eggs per hen housed, target curves and gaps, uniformity, comparisons between flocks, water/feed ratio, cost price, farm record book.
By the end of this level, you will be able to
- ✓Calculate and interpret the technical indicators of a broiler or layer flock
- ✓Compare a flock with the standard and with another flock to find the real cause of a gap
- ✓Measure uniformity and cost price with your own figures
- ✓Keep a complete record book and turn it into simple tables and charts
10 lessons · a 5-question quiz after each lesson · a level exam (30 questions, 80%) · verifiable certificate · Poultry Technician Certificate on passing. Lessons open to registered students who have passed the level 9 exam.
- 1The technician's indicators: daily gain, feed conversion, livability, efficiency index, eggs per hen housedA farmer says "the flock went well". A technician says "livability 94.3%, average weight 2.1 kg at 42 days, feed conversion ratio 1.75, efficiency index 270". The first sentence allows nothing; the second allows you to compare, correct and improve. This lesson opens the last level of the Technician cycle: it sets the five figures you must be able to calculate in your head, on any flock, in an open-sided house, under the climate of Côte d'Ivoire.12 min read · 5-question quiz
- 2Comparing with the standard: read a target curve, calculate the gap, know whether it is seriousA weight of 720 g at 21 days: is it good or bad? Alone, the figure means nothing. Compared with a target of 800 g, it means "minus 10%", and minus 10% at three weeks means "act this week". The technician never judges a figure on its own: they place it next to a target curve, calculate the gap and decide, with a grid, whether the gap is normal, to be watched or serious. This lesson gives you the curve, the formula and the grid.12 min read · 5-question quiz
- 3Uniformity: weigh a sample, calculate the coefficient of variation, actTwo flocks have the same average weight of 1,500 g at 28 days. In the first, almost all the chickens weigh between 1,350 and 1,650 g: the buyer takes the whole lot the same day. In the second, a third weigh 1,100 g and another third 1,900 g: the buyer sorts, argues, comes back twice, and the small ones eat for another week. The average hid everything. Uniformity is the figure that tells you whether your birds look alike, and it is one of the most profitable to watch.12 min read · 5-question quiz
- 4Comparing two flocks, two houses, two seasons: finding the real cause"The March flock was bad because the feed was bad." It is the sentence we hear most often, and it is rarely the right one. In March, it was 34 °C, the water tank was in the sun, the feed batch had changed, and the previous flock had been sold three days late, which shortened the downtime. Four things changed at the same time: which one cost 50 points of efficiency index? This lesson teaches you to compare with method so as to blame the right culprit, because a wrong cause leads to a wrong correction.12 min read · 5-question quiz
- 5Water and feed as signals: the water/feed ratio and its alertsA sick chicken stops drinking normally twelve to twenty-four hours before showing a visible sign. A hot chicken drinks more and eats less from the first hour. A blocked drinker shows on the water meter before it shows on the birds. Water and feed are the only two things we measure every day on the whole flock, without catching a single bird: they are the technician's best early-warning signals, provided you know how to read them together, in a single figure, the water/feed ratio.12 min read · 5-question quiz
- 6Cost price per kilo and per egg, item by item, with your own figuresMany farmers know their selling price per kilo and have no idea what that kilo cost them. So they know whether they collected money, not whether they made any. The cost price is the figure that turns a flock into a result: what each kilo of live chicken, or each egg, really cost to produce, all included. This lesson gives you the structure of the calculation, item by item, and the share each item usually weighs. The amounts themselves will be yours: those of your invoices, your region, your season.13 min read · 5-question quiz
- 7Simple tables and charts: from the notebook to the phone or computerA well-kept record book contains everything: the dead, the water, the feed, the weighings. But forty-two lines of figures speak to nobody, not even to the person who wrote them. Put the same figures on a curve, and the week-3 slip jumps out at the owner in two seconds, without explanation. This lesson teaches you to move from the notebook to the table, from the table to the chart, and from paper to the phone, with the tools you already have in your pocket.11 min read · 5-question quiz
- 8The perfect farm record book: what to note every day, every week, at every end of flockEverything you have learned in this level (indices, curves, uniformity, comparisons, water/feed ratio, cost price) rests on one thing: figures written the same day, in the right place, by someone who signs. Without a record book, a technician can prove nothing, compare nothing, correct nothing; they remember, and memory always tidies things up. This lesson describes the complete farm record book: its three parts, its model tables, and the rules that make it a reliable document for you, for the local vet and for the buyer.12 min read · 5-question quiz
- 9Field exercise: calculate daily gain, feed conversion and uniformity on your last flockUntil now, the figures were those of the lesson. This time, they are yours. You are going to open the record book of your last flock (or of the current flock), gather five pieces of data, work through four calculations and fill in a one-page sheet. In two hours, you will have the complete flock line of your farm, the one a technician presents to their owner. And if a piece of data is missing, you will have found your first job: making it available for the next flock.12 min read · 5-question quiz
- 10Case study: analyse a failed flock from start to finish and write the correction planAn owner from the Abengourou area calls in April: "I lost money on my March flock, the feed was bad, I am changing supplier." He has the record book, the delivery notes and the weighing tickets: everything needed to do better than guess. This lesson takes that flock from the first to the last day, with its real technical figures, applies the methods of the level one by one, names the causes in order of weight, and writes the correction plan the technician hands to the owner. It is the typical exercise of the Technician Certificate exam.14 min read · 5-question quiz
In conclusion
With this level passed, you obtain the Poultry Technician Certificate: you understand the bird, the feed, the house, health and the figures. The Expert cycle (levels 11 to 15) then trains the farm manager and the adviser.
