Compound beta-mannase and lactobacillus feed additive

Abstract

The invention discloses a compound beta-mannase and lactobacillus feed additive. The feed additive comprises the following components in part by weight: beta-mannase 2-8, xylanase 24-30, beta-glucanase 9-15, cellulose 28-33, pectase 20-27 and Enterococcus faecium fermentation liquor 90-110. The invention also discloses an Enterococcus faecium strain EF1008. The feed additive of the invention can be added in feed for egg-laying chickens in a proportion of 0.03 to 0.1 percent. The feed additive can improve the egg laying rate of the egg-laying chickens and can be used at a high rate by animals and reduce the cost of the feed. In the feed additive, the Enterococcus faecium can promote the micro ecological balance in the intestinal tract, improve body immunity and reduce the death rate of livestock in a stressful environment.

Description

technical field

[0001] The invention belongs to the field of poultry feed additives, in particular to a compound β-mannanase and lactic acid bacteria feed additive and its application in laying hen feed. Background technique

[0002] At present, most laying hen feed materials contain more anti-nutritional factors, which not only affects the digestion and utilization rate of animals, but also causes waste of feed resources and environmental pollution. In addition, egg products also have problems such as drugs, hormones, toxic and harmful substances exceeding the standard, and the deterioration of the breeding environment, which has become a bottleneck affecting the sustainable development of my country's laying hen farming industry. Research, development and utilization of "green", "safe" and "environmentally friendly" feed should be an effective way to solve the above problems.
