Abstract

The invention relates to a preparation method of a laying hen feed additive capable of improving laying rate. According to the preparation method, a saccharomyces cerevisiae seed solution and a barleylactobacilli seed solution are subjected to mixed fermentation; and simultaneously, a bifidobacteria seed solution, a bacillus subtilis seed solution and a clostridium butyricum seed solution are subjected to mixed fermentation. The preparation method adopts a technology of grouped fermentation and mixed fermentation of double strains or three strains in each group, simultaneously adopts a multistage continuous culture mode, and is favorable for developing the laying hen feed additive capable of improving the laying rate.

Description

technical field [0001] The invention relates to the field of feed additives for laying hens, in particular to a preparation method for a feed additive for laying hens that can improve egg production rate. Background technique [0002] Studies have shown that the diet of laying hens has a direct impact on the quality and efficiency of laying eggs. Healthier laying hens usually have higher yields. The nutritional distribution of hens to eggs can be judged by evaluating the size and composition of eggs. The use of probiotics as additives in animal feed is becoming more and more common due to the desire for "natural" products and people's desire for healthy farming and healthy food. The use of feed additives, such as probiotics, aims to provide a more "natural" and healthier way to maintain the health and performance of laying hens. [0003] Guo Xiaoquan and others added probiotic preparations to the feed of layer hens, which increased the egg production rate by 8.1%, increased...
