【摘要】 将48头育肥猪(杜×长×大)随机分为2组,每组3个重复,在同一玉米-豆粕型基础日粮中分别添加0.1%半乳甘露寡糖(GMOS)和50 mg/kg金霉素(CTC),进行了46 d的对比试验。饲养试验结束后,从2个处理的每个重复分别选择1头阉公猪空腹采血10 mL,以检测这2种添加剂对其血清生化指标和激素水平的影响。更多还原

【Abstract】 Forty-eight finishing pigs(Duroc×Landrace×Yorkshine) were randomly allocated to two groups with three replicates of each.All of pigs were fed with the same basal corn-soybean meal diet,one supplemented with 0.1% galacto-mannan-oligosacharrides(GMOS) and the other supplemented with 50 mg/kg chlortetracycline(CTC).At the end of the feeding trial for 46 days,six hogs from each replicate were collected 10 mL blood samples in empty stomach for detecting some serum biochemical indices and hormones levels influenced by the two additives.更多还原
