Improve the laying rate of green shell hens

Adding 4 kg to 10 kg of dicalcium phosphate per ton of feed when chickens raised in poultry cages for sale can reduce the mortality of green shell hens. Phosphorus is essential for maintaining high survival, growth and egg production rates under heat stress conditions. At the peak of laying eggs in caged chickens, the available phosphorus in the diet was 0.45%-0.5% (total phosphorus 0.65%-0.75%), and the available phosphorus in the old chicken diet gradually decreased to 0.4. % (total phosphorus 0.75%), the effective phosphorus content of the chicken in the whole growing season was maintained at 0.5%.

 

Supplementing the proper amount of zinc in the laying hen feed in battery cage system can increase the variety of enzymes in the liver of the chicken, and increase the egg production rate. If the amount of manganese is added to the feed, the number of soft shell eggs produced by the laying hen can be significantly reduced.
