Lactobacillus fermented feed for laying hens and preparation method of lactobacillus fermented feed

Abstract

The invention relates to a lactobacillus fermented feed for laying hens and a preparation method of the lactobacillus fermented feed. The preparation method comprises the steps: with lactobacillus plantarum and lactobacillus acidophilus as fermentation liquids as well as maize, bean pulp and bran as fermentation raw materials, mixing 1-3.0% of the fermentation liquids (the ratio of the lactobacillus plantarum to the lactobacillus acidophilus is equal to 1 to 1), 1-3.0% of brown sugar and 30-35% of water according to weight percentage; mixing the fermentation raw materials according to weight percentage: 30-35% of the maize, 50-55% of the bean pulp and 15-20% of the bran; mixing 60-65% of the fermentation raw materials and 35-40% of the fermentation liquids; and then, fermenting at the temperature of 20 DEG C or more than 20 DEG C for 7-15d. After the fermented feed is fed to laying hens, the laying rate can be increased by 6-9%, the feed to egg ratio can be reduced by 5-15%, the quality of an egg can be improved, the oxidation resistance, bird flu H9N1 and Newcastle disease antibody level of the laying hens can be improved, and the disease resistance of an organism can be enhanced. The preparation method is simple in preparation process, low in equipment requirement and extremely easy to popularize.

Description

technical field [0001] The invention relates to a lactic acid bacteria fermented feed for improving the production performance of laying hens and a preparation method thereof, belonging to the field of microbial fermented feed. Background technique [0002] Many studies have shown that lactic acid bacteria can regulate the gastrointestinal environment of animals, improve immunity, change the activity of certain enzymes in the intestine, degrade some anti-nutritional factors in feed, promote the absorption of nutrients, improve feed conversion rate, and increase production performance. Improve the quality of animal products, reduce the fat and cholesterol content of eggs, remove feces odor, and reduce environmental pollution. At present, probiotics are widely used, which are often used in the form of drinking water after dilution. It is difficult to colonize animals quickly. It is an ideal way to use fermented feed of probiotics and add it to animal diets in a certain propor...

Problems solved by technology

[0003] Generally, micro-ecological preparations are mostly in the form of additives to drink water or add to chicken feed in a certain proportion. They need to pass through the digestive tract before they can play a role. The feed is fermented with Lactobacillus plantarum and Lactobacillus acidophilus, especially for chicken feed. Fermentation, there is no literature report yet
