Monitoring: daily records, alert thresholds, curves, and the moment to call

This lesson is part of Farm health technician specialisation. It opens to every registered student, from free registration. Levels 1 to 5 and the tracks remain readable by everyone.

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.

• ✓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

1. Recording three houses: the same measure, the same time, the same base
2. Thresholds per house, recalled; farm thresholds, new
3. Drawing a curve: seeing the shape before the figure
4. The moment to call: the farm green-orange-red plan
5. Going further

• •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.
