Pig feed additive and preparation method thereof

Abstract

The invention discloses a pig feed additive and a preparation method thereof, belongs to the technical field of feeds, and solves the problems that the existing feed additive is single in raw material and relatively low in effect. The pig feed additive is formed by combining fermentation products with liquid water contents of smaller than or equal to 16wt% obtained by respectively fermenting bacteria liquids of 18 parts of aspergilli group, 18 parts of microzyme group, 30 parts of bacillus group and 40 parts of complex bacteria group in parts by weight. The preparation method comprises the following steps of: preparing a culture medium; cooling; diluting indigenous bacteria; inoculating; fermenting; drying; mixing; and packaging. The feed additive disclosed by the invention contains 20 types of probiotics, and has the effects of adjusting pig intestinal flora balance, controlling intestinal diseases, improving immunity, enhancing digestion function and improving feed conversion rate.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a pig feed additive and a preparation method thereof. Background technique [0002] Pork is the main meat in people's daily life. At present, the scale of pig farms is expanding day by day. In order to maximize economic benefits, some pig farmers use feed added with growth hormones and antibiotics to promote the growth of animals, or to prevent and control certain diseases. However, long-term use of antibiotics has many negative effects, antibiotic residues and drug resistance have brought food safety hazards, and their excrement has aggravated environmental pollution, which has seriously affected human health. After the outbreak of the clenbuterol incident, the Ministry of Agriculture issued an emergency notice overnight, urging the animal husbandry and veterinary authorities at all levels across the country to further strengthen the supervision of feed and pig breeding.

AI Technical Summary

Problems solved by technology

However, most products contain a single strain of bacteria, and the actual effect is not obvious. In addition, in the production process of probiotic feed additives, the optimal conditions for the fermentation of single-strain feed additives can be selected in the production process of probiotic feed additives. During the preparation of additives, due to the simultaneous existence of anaerobic bacteria and aerobic bacteria or the large differences in the culture conditions of different bacteria, the optimal conditions of the two bacteria cannot be achieved at the same time, which reduces the product quality and product effect.
