Viable microbe fermentation compound feed for layer chickens in laying period and production method thereof

Abstract

The invention discloses a viable microbe fermentation compound feed for layer chickens in a laying period and a production method thereof. The feed is prepared by mixing the following raw materials: 12%-16% of biodegradable bean pulp, 8%-10% of polypeptide biological blood power, 60%-66% of mixed feed powder, 8%-12% of feed additives and 1%-5% of animal oil. According to the invention, the utilization rate of the feed is improved through exogenous enzyme and microbial fermentation; through the beneficial viable microbes, the flora balance in the intestinal tract of a layer chicken can be regulated and the anti-stress ability of the layer chicken can be improved; and pathogenic bacteria in the feed and the bodies of the layer chicken can be inhibited and killed through organic acid and bacteriocin generated by microbial metabolism. No antibiotics, pigment or harmful additive is added in the viable microbe fermentation compound feed, and the viable microbe fermentation compound feed has the functions of effectively inhibiting the growth of harmful bacteria, regulating flora balance in the intestinal tract of a layer chicken and improving the immunity of layer chickens; moreover, eggs laid by chickens fed with the feed are full of nutriments and is free of residues of substances harmful to a human body.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and relates to a compound feed for laying hens and a production method thereof, in particular to a live microbial fermented compound feed suitable for laying hens without antibiotics, pigments and harmful additives and its production method. Background technique [0002] Eggs are a common food for people and also one of the important nutrients. In order to improve the egg production rate of laying hens and prevent bacterial diseases of laying hens, the method adopted in the early stage is to add some antibiotics, such as aureomycin, oxytetracycline, bacitracin zinc, etc., to the feed of laying hens. This method is simple and can achieve the desired effect, but its negative effects are: 1. The antibiotics that have not been metabolized are accumulated in the eggs through the fallopian tubes, causing the antibiotics in the eggs to seriously exceed the standard, endangering the health of consum...

Problems solved by technology

Among these additives, organic acids inhibit the growth of harmful bacteria and promote the proliferation of beneficial bacteria by lowering the pH value of the intestinal tract. However, organic acids can cause corrosion to equipment, troughs, etc., and the addition cost is high, so the application is limited; Enzyme preparations can improve feed utilization, reduce the side effects of anti-nutritional factors such as non-starch polysaccharides, and reduce the incidence of nutritional diarrhea, but there are problems such as unstable enzyme activity and inaccurate effects; oligosaccharides can enhance animal immunity and promote Animals have multiple activities of intestinal beneficial bacteria proliferation and direct adhesion to harmful bacteria, but the impact of oligosaccharides on animal physiological functions is closely related to factors such as animal feed, animal stage, animal physiological state, etc. The use of polyoligosaccharides; the research on the replacement of antibiotics by Chinese herbal medicine has a long history, but the theoretical basis is still unclear at present, the effects of different prescriptions vary greatly, the amount of addition is large, and the cos
