Scientific weighing of broiler breeder chickens

It is important, timely, accurate and representative. It is generally weighed once a week from the third week (once every two weeks after the egg laying peak). To achieve random sampling, samples can be taken from 8 different locations in the henhouse. The number of chickens accounts for 5 to 10% of the whole flock. The specific number is 50 to 100, not less than 50. It is said that important chicken fasting is best in the morning, which can be carried out on weekends or restricted feeding days (at the same time on the same day every week). Weigh the chickens one by one, and be responsible for weighing the chickens, reading and recording. The amount of medicine should be corrected at any time, the smaller the sensitivity, the better, with a minimum scale of 10 grams or 20 grams.
