Technical Field
The invention belongs to the technical field of laying hen feed additives, and particularly relates to an additive prepared from crayfish shells and used for improving calcium and phosphorus absorption of laying hens.
Background
The laying hens are special laying hens for laying eggs, different from meat-type chickens, the main subjects of people for raising the laying hens are to improve the quality of eggs and maintain or improve the egg yield, the eggs are the main income sources for raising the laying hens, the laying hens are very important for absorbing calcium and phosphorus in the raising process, the laying hens need a large amount of calcium to form eggshells, thin-shell eggs or soft eggs can be produced due to calcium deficiency in daily ration, 1 chicken eats 50-70 g of feed every day, the utilization rate of the calcium in the feed is only 60%, and the calcium in the feed is not enough. Therefore, a proper amount of additives are required to be added into the laying hen compound feed to supplement deficiency, and phosphorus plays an important role in the formation of bones, eggshells and somatic cells of chickens and the utilization of carbohydrates, fat and calcium. In particular, hens need more phosphorus because the egg yolk contains more phosphorus. The required amount of phosphorus in the chicken ration is 0.6 percent, wherein the effective phosphorus is 0.5 percent. Meanwhile, the proportion of calcium and phosphorus should be paid attention to in the additive, and no matter how much calcium and phosphorus are little or how much phosphorus and little calcium are little, the additive can have adverse effects on the health and growth of the chicken, the egg laying and the quality of the eggshell.
In the existing additive of the laying hen feed, calcium and phosphorus absorption rates of the laying hen are low, so that the calcium and phosphorus absorption rates of the laying hen are poor, and further the health of the laying hen and the quality of eggs laid by the laying hen are influenced.
