Feed additive and use thereof

Abstract

The invention provides a feed additive, which is characterized in that: the feed additive is prepared by the following steps: 1) preparing strains; 2) fermenting, namely uniformly mixing bran, corn flour, pine needle, honey and the strains in a weight ratio of 60:20:5:1:14, adding water of which the amount is 10 percent that of the total weight of the mixture into the mixture, uniformly mixing the mixture and fermenting the mixture in a container at the temperature of between 25 and 28 DEG C for 4 to 5 days; and 3) extracting leavening, drying the extracted leavening in the shade, bagging the dried leavening and sealing the bagged leavening. Use of the feed additive comprises the following steps: uniformly mixing a dry mixed feed and the feed additive in a weight ratio of 100:2; fermenting the mixture at the temperature of between 25 and 28 DEG C for 4 to 5 hours until yellow wine smell is emitted; and feeding livestock with the fermented mixture serving as the feed. The feed additive has reasonable formula and low cost. The feed is fully fermented by using microorganism fermentation technology to generate absorbable profitable florae and can save 25 percent of feed and increase more than 30 percent of nutrition. The feed accelerates the growth of the livestock, brings forward marketing time and can reduce more than 80 percent of diseased caused by bacillary dysentery.

Description

technical field [0001] The invention provides a feed additive and its usage, belonging to the technical field of feed additives. Background technique [0002] At present, the commercially available feed additives mainly rely on imported amino acids, which have good performance but are expensive when added to feed; some additives are mainly hormones, although they can also accelerate the growth of livestock, but the meat contains more hormones, which is harmful The human body has certain side effects. Contents of the invention [0003] The object of the present invention is to provide a feed additive capable of overcoming the above defects, with reasonable formula, low cost and good eating effect and its usage. Its technical solution is: [0004] A preparation method of a feed additive is characterized in that the following steps are adopted: 1) preparing strains; 2) fermenting: mixing bran, corn flour, pine needles, honey, and strains in a weight ratio of 60:20:5:1:14 M...
