Abstract

The invention provides a feed additive for improving the egg quality of laying hens. The additive is characterized by comprising the following raw materials in parts by weight: 24-45 parts of gynostemma pentaphyllum, 24-45 parts of pomegranate rind, 20-40 parts of Symphytum officinale, 20-40 parts of tartary buckwheat, 10-20 parts of hawthorn fruits, 10-20 parts of dodder seeds, 5-10 parts of Chinese yams and 12-24 parts of fish scale enzymolysis extract. The feed additive can reduce the cholesterol of eggs of laying hens, improve the laying rate, and reduce the cracking rate of eggs.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a feed additive for improving egg quality of laying hens. Background technique [0002] my country is the country with the largest number of laying hens in the world, but the overall production level of laying hens in my country is not high at present, and there is a big gap with the world's advanced level, mainly reflected in the short laying cycle and low egg production of laying hens. The laying period of laying hens in advanced countries has generally been extended to more than 80 weeks of age, with a total egg production of more than 20 kg / hen, while the general breeding period of laying hens in my country is 65-70 weeks of age, and the total egg production is less than 15 kg / Only. The reason is that in addition to the relatively backward feeding and management level, it is also related to the backward feed nutrition research of laying hens. The egg production rate ...
