Method for preparing egg-chicken feeds by utilizing lactobacillus fementation

Abstract

The invention provides a method for preparing egg-chicken feeds by utilizing lactobacillus fementation, which belongs to the field of poultry animals feeds, and uses corns and mixed meal as raw materials, and applies lactobacillus fementation to prepare egg-chicken feeds. The method for preparing the egg-chicken feeds by utilizing the lactobacillus fementation designs and tests through a quadratic regression orthogonal rotation combination design method, builds an orthogonal regression model, analyzes the orthogonal regression model to obtain fermentation parameters of lactic acid bacteria for preparing high lactic acid bacteria egg-chicken feeds, microbial strains which are used during fementation of lactic acid bacteria are mixed bacteria of lactobacillus plantarum and lactobacillus acidophilus, the volume radio of the lactobacillus plantarum and the lactobacillus acidophilus in the mixed bacteria is 1:1, and the number of lactic acid bacteria in the mixed bacteria in each milliliter is not lower than 108. The method for preparing the egg-chicken feeds by utilizing the lactobacillus fementation obtains the fermentation parameters of the lactic acid bacteria for preparing the high lactic acid bacteria egg-chicken feeds by building the orthogonal regression model, and improves number of live bacteria of the lactic acid bacteria in the egg-chicken feeds.

Description

technical field [0001] The invention belongs to the field of animal and poultry feed, and in particular relates to a feed for laying hens fermented by lactic acid bacteria and a preparation method thereof. Background technique [0002] Lactic acid bacteria are a kind of probiotics. Many studies have shown that lactic acid bacteria can promote animal intestinal digestion, improve immunity, inhibit the growth of pathogenic microorganisms in the intestinal tract, promote the absorption of nutrients, improve feed conversion rate, and promote animal health. Probiotics with main components are widely promoted and used. Using lactic acid bacteria to ferment the feed can degrade the toxins in the feed, which greatly improves the safety of the feed. At the same time, the lactic acid bacteria used in the fermentation can produce a large amount of organic acids and lactic acid bacteria, which can inhibit the growth of pathogenic bacteria. And lactic acid bacteria ferment the feed, wh...
