"Safe" pig feed additive developed by Yunnan Agricultural University

Introduction: Yunnan Agricultural University has recently developed a feed additive with natural plant active ingredients as the main body, which has opened up a new way to solve the problem of meat food safety and the "green barrier" faced by China's livestock and poultry export This feed additive formula is based on 16 Chinese herbal medicines such as Astragalus, angelica, white peony, tuckahoe and purple Salvia miltiorrhiza According to the different physiological characteristics of three different growth stages of piglets, Chinese pigs and big pigs, it is composed of three groups The results showed that the extract of Chinese herbal medicine had strong antibacterial ability, and had strong antibacterial effect on the main pathogenic bacteria E.coli, Salmonella, Proteus and Streptococcus Through the test of antibiotic and stimulant residues in pork and viscera, it is proved that the feed additive has no residue, drug resistance and pollution Compared with the use of antibiotics and chemical synthetic drugs as feed additives, the use of this Chinese herbal medicine feed additive can reduce diarrhea of piglets by more than 15%, reduce disease prevention and drug cost for promoting growth by more than 20%, and significantly improve the production performance of pigs At the same time, this kind of Chinese herbal medicine additive increased the intramuscular fat content by 52.77%, decreased the diameter of muscle fiber by nearly 8%, and increased the density of muscle fiber by 4.7%, and improved the quality of pork Experts believe that the feed additive developed by Yunnan Agricultural University has significant environmental benefits, which not only reduces the pollution of the production environment, but also completely avoids the pollution of the environment caused by the discharge of antibiotics and chemical synthetic drugs from pig feces When consumers eat the pork and its series of products with this additive, they will not produce anti drugs Sex, thus improving the therapeutic effect of antibiotics on human diseases The direct economic benefit of using this additive is also considerable It is understood that at present, Yunnan Agricultural University has produced a series of composite premixed feed for pigs with natural plant effective ingredients as the main body, about 300 tons, which has been successively popularized and applied in pig farms and feed factories in Kunming, Chuxiong, Yuxi, Honghe and other places in Yunnan Province In Xinfeng pig farm, 50 tons of this compound premixed feed for suckling pigs were used to prepare the full price feed, and the cost per ton was reduced by 400-500 yuan A total of 5000 tons of full price feed for suckling pigs were prepared, with a new profit of 2-2.5 million yuan We have achieved both ecological and economic benefits In addition, the production of this feed additive requires a large number of Chinese herbal medicines, and the vast mountainous and semi mountainous rural areas can increase their income by planting Chinese herbal medicines (author:) share to feed Weibo share to:
