China conquers the problem of raising pigs in the world

Introduction: growth stagnation will occur after weaning of piglets, and piglets may have diarrhea during trafficking These problems, which have long plagued the world pig industry, are now tackled by an expert group headed by Associate Professor Wen Lixin of Hunan Agricultural University They discovered and named three new pig diseases for the first time in the world, and successfully promoted a series of health pig raising technologies After being appraised by experts, the series technology of health pig raising is considered as an innovative research result, which not only has high academic value and theoretical significance, but also has great production and application value Before, after weaning, piglets tended to lose fat, reduce immunity, and develop edema disease, resulting in a loss of more than 6 billion yuan per year in China; nearly 200 million piglets were trafficked each year in China, resulting in a loss of more than 10 billion yuan per year due to piglet diarrhea, death and treatment drugs; and 15 billion yuan per year due to reproductive stress diseases, such as sows' lack of oestrus Yuan According to incomplete statistics, the global pig industry loses more than 200 billion yuan every year due to various major stress diseases In 2002, Hunan Agricultural University and Changsha green leaf Biotechnology Co., Ltd jointly formed a scientific and technological research team to overcome this world problem After three years of technical research, experts first found and named three important new diseases in the world, namely sow production reproductive stress syndrome, piglet trafficking diarrhea syndrome and drug-induced constipation of pigs, and carried out research on its pathogenesis, pathogenesis, main clinical symptoms and comprehensive prevention and control measures, and made breakthrough progress On the basis of these achievements, five comprehensive prevention and control measures for stress diseases of pigs have been developed, and the compound premixed feed for anti stress pigs has been developed At the same time, eight high-tech anti stress products have also been developed The results showed that by strengthening the health care of pigs to improve the disease resistance, various common diseases could be greatly reduced or eliminated, the average time of pigs on the market at present could be shortened from 165 days to 135 days, and the quality of meat products could be improved, with an increase of 40-110 yuan per pig.
