中草药饲料添加剂防治仔猪腹泻的应用

Application of Chinese Herbal Feed Additives to Control Piglet Diarrhea

仔猪腹泻是指仔猪在其生长发育过程中因消化机能不健全,尤其是在出生后3~5 d内,消化器官尚未完全发育,肠道功能不健全,免疫力低下,易受细菌、病毒、霉菌毒素等各种致病因子侵袭而发生腹泻。仔猪腹泻不但使仔猪的生长受阻、饲料利用率降低、甚至造成死亡,还会使仔猪体内营养物质流失,引起营养不良、抗病能力下降以及各种维生素及矿物质缺乏,从而严重影响仔猪的生长发育和生产性能,同时也影响种猪群的繁殖性能和产品品质。目前,虽然在我国猪场已广泛应用抗生素来防治仔猪腹泻,但由于抗生素的滥用以及环境污染等因素的影响,其耐药性不断增加。因此,寻找新的防治措施已成为当务之急。

Piglet diarrhea refers to piglet in the growth and development process due to digestive function is not perfect,especially in the 3~5 d after birth,digestive organs are not fully developed,intestinal function is not perfect,low immunity,vulnerable to bacteria,viruses,mycotoxins and other pathogenic factors invasion and diarrhea.Piglet diarrhea not only prevents the growth of the piglet,reduces the utilization rate of feed,and even causes death,but also causes the loss of nutrients in the piglet,causing malnutrition,decreased disease resistance and various vitamin and mineral deficiencies,which seriously affects the growth and development and production performance of the piglet.At the same time,the breeding performance and product quality of breeding pigs were also affected.At present,although antibiotics have been widely used in pig farms in China to prevent and control piglet diarrhea,due to the abuse of antibiotics and environmental pollution and other factors,their resistance is increasing.Therefore,it is urgent to find new prevention and control measures.
