摘要
以窝为单位将 70窝哺乳仔猪随机分为 7组 ,设 1个对照组 (试验I组 ) ,6个试验组。试验组分别添加 2 0 0mg/kg派富 (含芽胞杆菌等复合微生态制剂 ) (Ⅱ )、1%的甲酸吡啶铬 2 0 0mg/kg(Ⅲ )、2 0mg/kg泰乐菌素 (Ⅳ )、1%中药免疫增强剂 (黄芪、远智等复合中草药 ) (Ⅴ )、1%的益康XP(酵母培养物 ) (Ⅵ )以及 2 0mg/kg的硝呋烯宗 (Ⅶ )。经过 15d的试验 ,其结果表明 :试验组较对照组提高日增重 11.37% - 34.12 % ,其中Ⅴ、Ⅵ组达到显著水平 (p <0 .0 5 ) ;提高采食量 1.5 9% - 12 .30 % ;降低饲料增重比 8.4 % - 2 0 .2 0 % ;降低仔猪腹泻频次 10 .34- 31.0 3%。经无菌粪样检验 ,试验各组大肠杆菌、沙门氏菌、葡萄球菌数均低于对照组 ,差异不显著 (p >0 .0 5 ) ;而乳酸杆菌、双岐杆菌均高于对照组 ,差异不显著 (p >0 .0 5 )。经部分血液指标分析 ,试验各组的血液各项理化指标均在正常范围内 ,且各组间差异不显著 (p >0 .0 5 )。
litters of healthy RongchangⅠsuckling piglets were selected and randomly divided into 1 control (groupⅠ) and 6 treatment groups. All 7 groups were fed with the same basal diet plus groups premixes manufactured by Chongqing Swine Science Academy (CSSA). Besides, the 6 treatment groups are supplemented with different additives respectively as follows: 200 mg/kg PAIFU (compound microbial preparation ) (Ⅱ), 200 mg/kg 1% organic chromium (Ⅲ), 200 mg/kg 1% tylosin (Ⅳ), 1% Chinese herbal immunity strengthening additives) (Ⅴ); 2% YIKANG XP( yeast culture) (Ⅵ) and 20 mg/kg XIAOFUXIZONG (Ⅶ). After 15 days,compared with the control group, the daily gain of treatment groups increased by 11.37-34.12%, among which the difference of group Ⅴand Ⅵ was significant; intake increased by 1.59-12.30%; FGR decreased by 8.4-20.20% and diarrhea frenquency decreased by 10.34-31.03% recpectively. Testified by means of aseptic feces sample assay, the number of E.Coli, Salmonella and Staphylococcus was lower than that of control and the difference was not significant(p>0.05). Hemotological and biochemistry indexes were within normal range and the difference among each group was not significant(p>0.05).
