First, before the restrictions on feeding should be too light or weaker chickens singled out or eliminated. Second, in order to avoid the occurrence of delirium during restriction of feeding, the deafness should be performed when the chicken is 7-10 days old or 6 weeks old. Third, meat breeder chickens should be fed from the age of 4 weeks. Fourth, the basic basis for feeding is weight. For the parent breeders of broiler breeders, from the age of 4 weeks, a random sample of the body weight should be taken each week, and each group should be tested for 5% or no less than 25 individuals. Weigh in the afternoon at the daily limit, and weigh at the stop day on the next day. Fifth, the amount of feeding depends on the comparison of chicken population weight and standard weight. When the chicken population weight is lower than the standard body weight, the feeding amount can be appropriately increased; when the chicken population exceeds the standard weight, the increase of the material amount can be suspended until the standard body weight is consistent. In addition, the difference between season and feed nutrient levels must also be taken into consideration when restricting feeding. In the winter when the house temperature is low, feed more, and when the house temperature is high in the summer, feed less, and when the nutrient level of the feed is low, you should feed more. 6. Limit the health of the flock when restricting feeding. When the flock is sick or vaccinated, free access should be temporarily resumed. 7. Ensure that each chicken has enough feed and water. The number of troughs and sinks should be sufficient and should be placed evenly. VIII. The breeding density should be appropriate. At the end of the breeding period, 6 chickens per square meter are required, and each group has no less than 500 chickens. (Source: Farmers get rich)
