Biological feed for pigs and preparation method of biological feed for pigs

Abstract

The invention relates to a preparation method of biological feed for pigs. The preparation method includes the following steps: S1. crushing 130-220 parts of corn, 80-280 parts of soybean meal, 30-90parts of rapeseed meal, 110-200 parts of sprayed corn bran, 80-220 parts of cottonseed meal, 160-260 parts of bran, 130-200 parts of rice bran meal and 40-90 parts of rice hull powder, and performingmixing so as to obtain dry powder; S2. adding 12-25 parts of lactic acid bacteria, 20-35 parts of active yeast and 13-23 parts of Bacillus to 230-300 parts of water, and performing diffusion so as toobtain a fermentation bacterial liquid; S3. adding 15-25 parts of amylase, 10-18 parts of a-galactosidase, 5-10 parts of xylanase, 10-15 parts of mannase and 5-10 parts of pectinase to the fermentation bacterial liquid, and performing fermentation so as to obtain a fermented liquid; S4. spraying the fermented liquid evenly into the dry powder, and performing even mixing so as to obtain a fermentation material; and S5. performing fermentation on the fermentation material so as to obtain the biological feed. Through the prepared biological feed, the balance of intestinal flora of pigs can be maintained, the digestibility of the feed is improved, and the growth rate of the pigs can be increased.

Description

technical field [0001] The invention relates to the technical field of biological feed, in particular to a biological feed for pigs and a preparation method thereof. Background technique [0002] Pork is sweet and flat in taste, rich in protein and fat, carbohydrates, calcium, iron, phosphorus and other nutrients. It is the main non-staple food in daily life. Loved by people. [0003] At present, pig feed is used to feed pigs in batches. The existing Chinese patent application with publication number CN109123162A can be referred to, which discloses a pig feed, which contains the following raw materials in parts by weight: 150-200 parts of wheat germ, 30-60 parts of soybean meal , 20-50 parts of fermented soybean meal, 20-50 parts of corn dregs, 10-30 parts of bone meal, 1-3 parts of calcium lactate, 0.01-0.05 parts of calcium bicarbonate, 10-15 parts of glucose, 0.001-0.003 parts of compound organic minerals , 5-10 parts of perilla, 20-40 parts of spinach. [0004] In ord...

Problems solved by technology

[0004] In order to promote the rapid growth of pigs, the feed often contains a large amount of macromolecular nutrients, which are not easily digested by pigs. Therefore, when pigs are fed with ordinary feed, the digestibility of the feed is low, which easily leads to the imbalance of the intestinal flora of pigs. Decreased immunity and affects the growth rate of pigs
