Problems solved by technology

[0003] In the prior art, the fermentation of plant-based feed is often due to the long storage time, resulting in too long fermentation time. As the fermentation continues, the high-energy feed will continue to produce acid until the pH drops to inhibit all bacteria. At this time, there is no Although spoilage bacteria and butyric acid bacteria are effectively killed, long-term fermentation leads to a gradual loss of energy and reduced nutrition in the silage, so the existing silage often cannot provide long-lasting and effective nutritional supplements.

Abstract

The invention relates to the technical field of feed additives, in particular to a silage additive as well as a preparation method and application thereof, and the silage additive is prepared from the following raw materials in parts by weight: 55-75 parts of fermentation raw materials; 15-30 parts of a microbial mixed strain; 4-10 parts of calcium carbonate; 0.3 to 1 part of a pH regulator; the microbial mixed strain is prepared from the following bacterial powder in percentage by weight: 12-18% of lactic acid bacteria; 15-20% of EM bacteria; 15 to 28% of lactobacillus acidophilus; 5-10% of enterococcus faecalis; 25-40% of saccharomyces cerevisiae; 6-12% of candida utilis saccharomycetes; and 5-9% of trichosporon cutaneum. The silage additive disclosed by the invention achieves the technical effects of long-term storage and stable nutrition, realizes the coexistence of the silage and the probiotics, and also realizes the purposes of high-energy intake of ruminants and supplement of the probiotics.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a silage additive and its preparation method and application. Background technique [0002] Silage is a kind of roughage fermented by sealing and fermenting under airtight and hypoxic conditions from vegetable feed with high water content. It is mainly used to feed ruminants. Ruminants are animals that digest food by returning it to their mouths for chewing. [0003] In the prior art, the fermentation of plant-based feed is often due to the long storage time, resulting in too long fermentation time. As the fermentation continues, the high-energy feed will continue to produce acid until the pH drops to inhibit all bacteria. At this time, there is no Although the spoilage bacteria and butyric acid bacteria are effectively killed, the long-term fermentation leads to the gradual loss of energy and reduced nutrition of the silage, so the existing silage often cannot provide lo...
