Abstract
  1. A total of 720 female broiler chicks was used to test the effects of 4 dietary concentrations of a Chinese herbal medicine (CHM) formulation (0.25, 0.5, 1 and 2g/kg), as an alternative for virginiamycin (VRG), on growth performance in broilers. 2. A total of 72 birds from non-supplemented, VRG and 0.5 g/kg CHM groups was selected and killed and the relative weights of the intestinal segments were assessed. 3. The CHM dietary treatments produced increased body weight gain at 7 to 21 d of age but not at 21 to 28 d of age compared with the non-supplemented and VRG groups. The CHM groups had a higher feed intake and a higher feed conversion ratio (FCR) than the VRG group between 21 and 28 d. 4. The dissection results showed that the liver colour of the birds in the CHM group varied less between animals than that of the VRG and the non-supplemented groups. Neither CHM nor VRG had any significant effects on either liver or intestinal tract weights. 5. It was concluded that the birds of the CHM group had better growth performance from d 7 to 21 but not thereafter. Further experiments are needed to elucidate the mechanisms underlying enhanced growth performance by CHM in broilers.
摘要
  1. 总共720只雌性肉鸡雏鸡被用于测试4种日粮浓度的一种中药配方(0.25、0.5、1和2克/千克)作为维吉尼亚霉素(VRG)的替代品对肉鸡生长性能的影响。2. 从不添加组、VRG组和0.5克/千克中药组中挑选并宰杀了总共72只鸡,并评估了肠道各段的相对重量。3. 与不添加组和VRG组相比,中药日粮处理使7至21日龄时的体重增加,但在21至28日龄时没有。在21至28日龄期间,中药组的采食量和饲料转化率(FCR)高于VRG组。4. 解剖结果表明,中药组鸡的肝脏颜色在个体间的差异小于VRG组和不添加组。中药和VRG对肝脏或肠道重量均无显著影响。5. 得出的结论是,中药组的鸡在7至21日龄时有更好的生长性能,但此后则不然。需要进一步的实验来阐明中药提高肉鸡生长性能的潜在机制。
