Matters needing attention in restricted feeding of broiler breeder chickens

The first restriction should remove or eliminate chickens that are too small and weak; the second restriction is easy to occur pecking addiction, and the beak should be cut off before feeding restriction; the third is from four weeks, randomly sampling and measuring the weight once a week to calculate the average weight as the basis for feeding restriction. It is best to measure 50 hens each time, weigh them in the afternoon when the limit is limited, and weigh them on the day when feeding is stopped every other day; the fourth restriction should pay attention to the health status of chickens. When the chicken flock is sick, the feeding restriction should be temporarily stopped, and individual sick chickens should be selected and raised alone; Fifth, it is necessary to ensure that each chicken has enough food and drinking positions to prevent uneven hunger and uneven development; sixth, it should be combined with control of light to achieve greater results.
