Feed additive for improving egg laying capacity of laying hen and preparation method thereof

Abstract

The invention discloses a feed additive for improving egg laying capacity of a laying hen and a preparation method thereof. The feed additive comprises the following raw herbal materials: herba epimedii, morinda officinalis, leonurus, glossy privet fruit, monthly rose, fructus psoraleae, codonopsis pilosula, rehmanniae vaporata, angelica sinensis, Chinese-date, herba cistanche, semen cuscutae, medlar, bighead atractylodes rhizome, astragalus membranaceus, folium artemisiae argyi and liquorice. The feed additive has the beneficial effects that the egg laying capacity of the lying hen can be effectively improved by the feed additive disclosed by the invention, and the feed additive also has the advantages of being pure nature, free of tolerance, small in toxic and side effects, and small in damage to a human body.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for improving the laying performance of laying hens and a preparation method thereof. Background technique [0002] In recent years, the poultry industry has developed rapidly, and the level of scientific breeding has also been continuously improved. However, due to the influence of various reasons in production, laying hens cannot reach the peak of egg production, or the egg production drops rapidly after reaching the peak. [0003] In recent years, feed additives have been used more and more widely in the laying process of laying hens. Feed additives promote the increase of laying hens' egg production, increase egg production rate, prolong the peak of egg production, greatly improve the level and efficiency of laying hens, but at the same time, they also bring a series of problems. Since most compound additives use chemically synthesized drugs such as h...

AI Technical Summary

Problems solved by technology

Since most compound additives use chemically synthesized drugs such as hormones, antibiotics, heavy metals, etc., feed additives increase the egg production of laying hens, increase egg production rate, and prolong the peak of egg production, but also lead to the reduction of drug residues in livestock products. The increase will not only lead to the development of drug resistance of pathogenic microorganisms, the decline of animal immunity and the decline of egg quality, but also directly endanger human health and the ecological environment. Scholars at home and abroad are currently seeking to improve and replace green additives of antibiotics.
