Feeding of young egg hens

For the breeding of high-quality rearing flocks in the first four days of life the chicken should be fed to the zero diet, consisting of feed with the most readily soluble and easily digestible nutrients (corn, wheat, soybean meal, fish meal, milk powder, etc.). The components of the diet should be a kind of grit with a particle size of 0.5-1.0 mm.

In the first 24 hours chickens must drink 8.5% solution of glucose or sugar with vitamin C at the rate of 1 g per 1 liter of water.

In the first week of life the food must remain in feeders and not to lie long it should be driven through the system every 3-4 hours.

In the future, we recommend using three-phase diet change: two grower and one pre-laying. Standards of nutrients and metabolizable energy for young are presented in Table 1.

At the age of 1-7 weeks it is recommended to use feed with a high content of protein and metabolizable energy at a low level of fiber and minerals. In organizing the feeding in this period it is important that youngsters reach the standard weight at the age of 4 weeks as it provides high productivity in the future.

It is unacceptable to change sharply the composition of the diet sharply at any time, but particularly in the first four weeks of life, as long as it can bring the chicken’s body out of balance with subsequent delayed growth.

To delay the pubescence of the chicken in the weeks 8-16, the level of crude protein and metabolizable energy in the feed should be reduced while crude fiber content increased.

Pre-layer period may be detached since 17th week, the feed with more crude protein and calcium has to be used.

Feeding front in conditions of limited feeding should be sufficient for the simultaneous approach of all birds to the feeders.

Youngsters should be transferred from one diet to another when reach the standard body weight.

Pre-laying diet is ceased as soon as egg-laying begins, and the flock is transferred to a special diet for a period of productive layers.
