Abstract

The invention provides a weaned piglet feed additive capable of replacing antibiotics and application of the weaned piglet feed additive, and relates to the technical field of feed additives. The weaned piglet feed additive capable of replacing antibiotics is prepared from a plant extract, a solid microecological preparation, solid organic acid and a carrier according to the mass ratio of 1: (0.5-0.8): (0.4-0.6): (2.8-3.5). The plant extract is prepared from the following components in parts by weight: 3.2-4 parts of a blackberry seed extract, 1.8-2.5 parts of a vine tea extract and 0.5-0.8 part of tea saponin. The solid microecological preparation is prepared from the following components in parts by weight: 3.3-4.2 parts of lactobacillus powder, 0.9-1.5 parts of bacillus licheniformis powder, 1.6-2.3 parts of bacillus natto powder and 2.8-3.6 parts of saccharomyces cerevisiae powder. All the substances in the feed additive are synergistic, the product can be effective and stable, thefeed additive can replace antibiotics to be used in weaned piglet feeding, the organism immunity of weaned piglets is effectively improved, the diarrhea rate is reduced, the feed conversion rate andthe growth performance of piglets are improved, and the effect of rapid fattening is achieved.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for weaned piglets that can replace antibiotics and an application thereof. Background technique [0002] Antibiotics have been widely used in pig production for more than 50 years. Numerous studies have shown that antibiotics have good effects in improving pig growth efficiency and feed utilization and reducing the occurrence of diseases. However, as people's requirements for health gradually increase, antibiotic residues in pork and microbial resistance are more and more concerned, and the use of antibiotics will be strictly limited. The European Union has banned the addition of antibiotics in feed since 2006, and the US Food and Drug Administration has phased out the use of non-medical antibiotics in livestock since 2013. In this context, research on seeking alternatives to antibiotics has become a research hotspot in the entire feed and breeding indus...
