选取健康、体重约56kg的杜x长×大育肥猪64头，将其分为对照组和试验组，每组32头。对照组猪饲粮为基础饲粮加黄霉素20mg／kg，试验组猪饲粮为基础饲粮加酵母培养物O．15％，比较研究酵母培养物和黄霉素对育肥猪的饲用效果。结果表明：①对照组猪腹泻频次为4；试验组猪健康状况良好。②试验组猪日均增重显著快于对照组猪（P〈0．05）。③试验组猪血清免疫球蛋白G极显著高于对照组猪（P〈0．01），且试验组猪血清猪瘟抗体含量显著高于对照组猪（P〈0．05）；试验组猪血清GPT、GOT活性显著低于对照组猪（P〈0．05）；试验组猪血清磷含量显著高于对照组猪（P〈0．05）；试验组猪血糖含量显著低于对照组猪（P〈0．05）；而两组猪血清TP、UN、TG、vLDL、Ca、Mg、口蹄疫抗体和圆环病毒抗体含量无显著差异（P〉0．05）。④试验组猪背膘厚、背肌纤维直径显著小于对照组（P〈0．05），但两组猪背肌pH值、肉色、大理石纹评分、滴水损失以及肌粗脂肪、肌糖原含量均无显著差异（P〉0．05）。说明与黄霉素比较，酵母培养物不仅对猪有更好的保健促生长作用，而且在不同程度上可改善猪的营养生化代谢和肉质。

The effects of yeast culture bred （ Duroc x Landrace x Yorkshire） and flavomycin on pig were studied. 64 healthy, three - way crossfinishing pigs about 56kg were divided into 2 groups： control and experimental group, each group 32 pigs. Basic diet was prepared according to recent pig＇s feeding standard in our country. The control group pigs were fed for basal diet supplemented flavomycin（20 mg/kg）, the experimental group pigs for that supplemented 0.15 % yeast culture. Formal feeding experiment peri- od was 40 days. Feeding experimental results were as follow. OThe frequencies of diarrhea pigs in the control group were 4 and the pigs in the experimental group were healthy. Q The average daily gain of pigs in the experimental group was markedly higher than those in the control group （ P 〈 0.05）. （~）IgG concentration in serum of pigs in the experimental group was greatly higher than that in the control group （ P 〈 0.01 ）. The antibody against swine fever in serum of the pigs in the experimental group was higher than that in the control group （P 〈 0.05）. The GPT, GOT activities in serum of the pigs in the experimental group were markedly lower than those in the control group（ P 〈 0.05）. P in serum of the pigs in the experimental group pigs was higher than that in the control group （ P 〈 0.05）, Glu in serum of the pigs in the experimental group was lower than that in the control group （ P 〈 0.05）, but TP, UN, TG, vLDL, Ca, Mg, antibody against foot-and-mouth disease and circovirus disease in serum of two group pigs had no remarkable differences（ P 〉 0.05）. QThe back-fat thickness and diameter of muscle fiber of the experi- mental group pigs were lower than the control group （ P 〈 0.05 ） ; but pH, color, marbling, drip loss, EE, glycogen in back muscle of two group pigs have no significant differences（ P 〉 0.05）. Based on above resuits the conclusion was made： comparing with flavomycin, yeast culture promoted growth and guaranteed health of pigs more markedly, and improved nutritively biochemical metabolism at various degree.
