Abstract

The invention provides a feed addictive for improving pork quality and increasing efficiency of feed utilization and preparation thereof, and belongs to the field of feed addictive. The feed addictive is composed of natural Chinese herbal medicine, is capable of improving metabolism function of pig and strengthening immunity function of pig, has no side effects, and thus improves the pork quality. In the same time, the feed addictive can also condition the intestinal tract health, promotes absorption and utilization of feed, increases utilization rate of feed and breeding benefit, and effectively decreases breeding cost and risk. The feed addictive is composed of following components in parts by weight: 5 to 15 parts of eucommia powder, 5 to 10 parts of poria cocos powder, 15 to 20 parts of anemarrhena powder, 5 to 9 parts of matrimony vine enzymolysis powder, 4 to 8 parts of clove, 5 to 8 parts of haw, 8 to 12 parts of composite polysaccharide extract, and 8 to 20 parts of fermented soybean meal. The preparation method is mixing the components mentioned above together.

Description

technical field [0001] The invention relates to a feed additive for pigs, in particular to a feed additive for improving pork quality and feed utilization rate, and belongs to the field of feed additives. Background technique: [0002] With the rapid development of the breeding industry and the continuous improvement of living standards, people's demand for meat products has changed from quantity to quality. Therefore, how to provide people with high-quality, delicious, safe and nutritious meat products is the future development of animal husbandry. direction. [0003] Feed is the foundation of modern aquaculture, and it is also the biggest cost of aquaculture. How to improve the utilization rate of feed can not only reduce the cost and risk of feeding, increase the efficiency of feeding, but also avoid the waste of resources, which has a positive impact on society and the environment. [0004] At present, the aquaculture industry generally has problems such as low feed uti...
