羔羊瘤胃酸中毒的研究——1.临床诊断与防制部份

STUDES OF RUMINAL ACIDOSIS IN DAIRY GOAT KID PARTS OF CLINICAL DIAGNOSIS AND CONTROL

研究了雅安地区以腹泻症状为主的羔羊疾病。结果表明该病为瘤胃酸中毒。过量单一饲喂玉米面是导致发病的根本原因。病羊表现出精神沉郁、腹泻、脱水、虚弱和全身衰竭。其血中乳酸浓度显著升高(P<0.01),血液浓缩,血细胞压积升高,瘤胃液pH值降低,纤毛虫数量显著减少,活性显著降低。防制原则为减少玉米面喂量,补充体液和纠正酸中毒。

The Kids'disease characterized by diarrhea, dehydration and high incidence in Yaan district was investigeted It was confirmed as ruminal acidosis in dairy goat kid by survey of clinical history, observation of symptoms, analysis of ration, determination of lactic level in blood pH value and member of infusorian in ruminal fluid as well as examination of faeces The main causative factors were deficency of sucking milk, cornmeal engoigement and lactic acidos The level of blood lactic acid of the kids with ruminal acidosis was significantly increased (P<0.01) The blood was concentrated The pH value, number and activity of infusorian in ruminal fluid were signifcantly decreased The disease could be controlled successfully by drinking enough milk and decreasing the amount of cornmeal in ration (10g/kgw/day) Meanwhile, the cornmeal should be supplied graduallly before the stage of weaning
