Problems solved by technology

Usually, in order to increase the absorption rate of livestock to feed, some people use the addition of cellulolytic bacteria such as actinomycetes, but the effect is not significant. What's more, antibiotics are added to the feed, although this can improve livestock. The digestion and absorption of feed can even improve its disease resistance, but the abuse of antibiotics is easy to produce drug resistance, which will cause food safety and cause great harm. damage

Abstract

The invention discloses a crop straw silage leavening agent, prepared from the following raw materials in percentage by weight: 50-60% of a microbial strain, 15-25% of a protective agent, 1-5% of a compound additive, 5-15% of carrier defatted rice bran, and 5-15% of light calcium carbonate, wherein the microbial strain is obtained by mixing of following bacterial powder in percentage by weight: 20-25% of lactobacillus plantarum, 20-25% of pediococcus acidilactici, 10-20% of lactobacillus acidophilus, 10-15% of enterococcus faecalis, 10-15% of lactobacillus buchneri, and 10-15% of lactobacillus paracasei. The leavening agent disclosed by the invention can be applied to preparation of a crop straw silage, and the invention also discloses a preparation method of the crop straw silage. The leavening agent disclosed by the invention can be used for fermenting various crop straws into available feed products, antibiotics are not used at all, and the digestivity to feeds of animals is improved, so that the crop straws are changed from waste into valuable, and the cost of raising livestock is reduced.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a crop straw silage starter and application thereof. Background technique [0002] China is a big agricultural country. The by-products of agricultural production (crop straw) in our country are more than 700 million tons annually, but only a small part is produced through silage and ammoniation or directly as roughage for animals, and more than 80% are not fully utilized. If it rots in the ground, it is directly burned and returned to the field, resulting in a great waste of resources. At present, the countries with developed agriculture in the world attach great importance to the comprehensive utilization of crop straw, and have basically formed a fertilization system of "straw + manure + chemical fertilizer". For example, the rice straw production in Japan is 15 million tons, accounting for about 3 / 4 of the total straw production in Japan, of which more than 2 / 3 of the ri...
