Compound feed additive for laying hens and preparation method of compound feed additive

Abstract

The invention discloses a compound feed additive for laying hens. The compound feed additive comprises 30-45 parts of compound Chinese herbal medicines, 18-32 parts of a compound bacterium preparation, 1-3 parts of a compound enzyme preparation, 0.5-1.5 parts of a vitamin preparation, 0.3-0.5 part of a trace element preparation, 1-3 parts of turf humic acid and carriers, wherein the compound Chinese herbal medicines comprise 10-15 parts of Chinese jujubes, 8-10 parts of radix Chinese angelica, 6-8 parts of Chinese wolfberry fruits, 2-3 parts of rhizoma atractylodis, 2-3 parts of dried orange peel, 1-2 parts of safflowers, 0.5-2 parts of radix salviae miltiorrhizae and 0.5-2 parts of fossil fragments; the compound bacterium preparation comprises composite viable bacterium agents and viable bacterium protecting agents in the mass ratio of the composite viable bacterium agents to the viable bacterium protecting agents being 6-7 to 1. According to the compound feed additive disclosed by the invention, no antibiotics, no pigments and no hormones are added to the compound feed additive, and a formula is optimized, so that the digestion absorbency, the production capacity and the autoimmunity of the laying hens are improved, the egg laying efficiency is improved, and the quality of eggs is improved.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a compound feed additive for laying hens and a preparation method thereof. Background technique [0002] Food safety is the top priority for people’s health. Various food safety problems appear in every link of food production. How to produce safe, healthy and standardized food from source to table is the key to eliminating unhealthy food. With the improvement of people's living standards, eggs have become people's daily necessities, and the demand for eggs has also increased significantly. However, due to the shorter physiological structure of the chicken's own intestinal tract, the ability to absorb and digest is poor, and the autoimmunity is obviously reduced after laying more eggs, and the egg production efficiency is low and seriously affects the quality of eggs. Contents of the invention [0003] The object of the present invention is to provide a compound feed additive for la...
