Probiotic fermented fodder for improving egg quality and preparation method thereof

Abstract

The invention provides probiotic fermented fodder for improving the egg quality and a preparation method thereof. The preparation method comprises the steps that lactobacillus plantarum, bacillus subtillis and phaffia rhodozyma are inoculated into corresponding fluid nutrient medium and are cultured for 18 to 24 hours at the constant temperature of 37 DEG C; then bacteria solutions are inoculated in proportion into a solid state fermented nutrient medium with potato dregs, bean dregs and the like as the main raw materials, and fermentation is performed for 48 to 72 hours at the temperature of 28 to 32 DEG C; and cryodrying at the temperature of 50 to 55 DEG C is performed, and then pulverization is conducted to obtain the probiotic fermented fodder. By adopting the probiotic fermented fodder, the laying rate of laying hens and the fodder conversion rate can be increased, the immunologic functions of the laying hens are regulated, the disease resistance is improved, the fodder antibiotics are replaced, the egg quality and the yolk color are improved, and the cholesterol content in an egg is decreased. A production process provided by the invention has the advantages of being low in investment, low in energy consumption, free of waste liquid pollution and the like, and meanwhile, a new approach is developed for utilization of agricultural by-products.

Description

technical field [0001] The invention relates to the fields of feed industry and animal husbandry, in particular to a probiotic fermented feed for improving egg quality and a preparation method thereof. Background technique [0002] Eggs are one of the important sources of human high-quality eggs, rich in essential amino acids such as methionine and lysine. At the same time, eggs also contain a lot of trace elements needed by the human body, such as calcium, phosphorus, iron, zinc, etc., which are our ideal natural food. However, under today's modern breeding conditions, laying hens are in a sub-healthy state, with low immune levels and frequent occurrence of reproductive system, intestinal and respiratory diseases, which seriously damage the interests of breeding enterprises. In order to improve economic benefits, laying hen farmers use a large amount of chemical drugs such as antibacterial and anti-inflammatory drugs and anticoccidial drugs in feed, which seriously affects...

However, under today's modern feeding conditions, laying hens are in a sub-healthy state, with low immune levels and frequent occurrence of reproductive system, intestinal and respiratory diseases, which seriously damage the interests of breeding enterprises

In order to improve economic benefits, laying hen farmers use a large amount of chemical drugs such as antibacterial and anti-inflammatory drugs and anticoccidial drugs in feed, which seriously affects the quality of eggs. In addition, it also causes problems such as drug residues and pathogenic bacteria resistance, which has caused serious harm to human health. great harm
