Feed additive for increasing intestinal amino acid content of growing and fattening pigs and promoting protein synthesis as well as preparation method and application of feed additive

Abstract

The invention relates to a feed additive for increasing intestinal amino acid content of growing and fattening pigs and promoting protein synthesis as well as a preparation method and application of the feed additive, and belongs to the field of feeds. The feed additive comprises metalloprotease, fish meal, enzymolysis protein peptide, transferred glucuronidase genetic lactobacillus, a Sichuan pepper extract and a carrier. The feed additive is free from harmless residues and free of drug resistance; all raw materials are matched for use, so that the effect is good, and the stability is ensured. The preparation method is characterized in that the raw materials are mixed based on ratio; the operation is simple and quick; the condition controllability is high. After the feed additive is addedto a feed of the growing and fattening pigs, the appetite and the growing performance of the growing and fattening pigs can be improved; the meat quality of the growing and fattening pigs can be improved; and moreover, the intestinal flora of the growing and fattening pigs can keep balance; the immunity and the oxidation resistance of the growing and fattening pigs can be improved; and moreover,the nitrogen and phosphorus emission in the excrement of the growing and fattening pigs can be reduced; the feed waste is reduced; and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a feed additive for increasing the intestinal amino acid content of fattening pigs and promoting protein synthesis, as well as its preparation method and application. Background technique [0002] Fattening pigs are generally pigs that have been bred for a period of time and have not yet been slaughtered. Generally, they refer to the stage when the weight of meat pigs is 60-100kg, which is the stage of pig growth sprint. Pigs grow fast at this stage, but require higher nutrition. In order to shorten the feeding cycle, obtain faster weight gain, lower feed-to-meat ratio and better meat quality, as well as reduce the excretion of nitrogen and phosphorus in manure, reduce feed waste and environmental pollution, and provide people with large quantity and high quality. Good pork and a healthy living environment need to improve the existing fattening pig feed to increase breeding benefits and ...

Pigs grow fast at this stage, but require higher nutrition

In order to shorten the feeding cycle, obtain faster weight gain, lower feed-to-meat ratio and better meat quality, as well as reduce the excretion of nitrogen and phosphorus in manure, reduce feed waste and environmental pollution, and provide people with large quantity and high quality. For good pork and a healthy living environment, it is necessary to improve the existing feed for fattening pigs to increase breeding benefits and solve the problems of unbalanced nutrition and low absorption rate of conventional feed
