ABSTRACT Groups were designated as a positive control (+C), negative control (−C), Amprolium (AM1), Aloe vera, 2.5 g/l water (AV2.5) and Aloe vera 5 g/l water (AV5) during the finisher phase. The experiment was conducted using 360 broiler chicks, which were divided into five different groups. Overall feed intake was significantly (P<.01) lower in Aloe vera supplemented groups. The overall weight gain was significantly (P<.01) higher in AV5 and AMI compared to –C. No significant difference was found in the feed conversion ratio between AMI and Aloe vera-treated birds. The caecal lesion, oocysts count and intestinal lesion were significantly (P<.01) reduced in Aloe vera-treated birds. The number of heterophils and total leucocyte count significantly (P<.01) decreased, while the number of monocytes and eosinophils increased (P<.01) in the treatment groups. From the results, it is also clear that the infection increased the monocytes and eosinophils and decreased the heterophils and TLC. In conclusion, the use of Aloe vera at the rate of 5 g/l of water produced encouraging results in broilers in comparison with Amprolium.

芦荟对球虫病肉鸡生长性能、白细胞计数及肠道损伤的保护作用

摘要组被指定为阳性对照 (+C)、阴性对照 (-C)、氨丙啉 (AM1)、芦荟、2.5 g/l 水 (AV2.5) 和芦荟 5 g/l 水 (AV5)终结者阶段。该实验使用 360 只肉鸡进行，它们被分为五个不同的组。芦荟补充组的总采食量显着降低（P<.01）。与 -C 相比，AV5 和 AMI 的总体体重增加显着（P <.01）更高。AMI 和芦荟处理的鸟类之间的饲料转化率没有发现显着差异。在芦荟处理的鸟类中，盲肠病变、卵囊计数和肠道病变显着减少（P<.01）。异嗜细胞数量和白细胞总数显着减少（P<.01），而单核细胞和嗜酸性粒细胞数量增加（P<.01）。01) 在治疗组中。从结果也可以看出，感染增加了单核细胞和嗜酸性粒细胞，减少了异嗜细胞和 TLC。总之，与 Amprolium 相比，以 5 g/l 水的比例使用芦荟在肉鸡中产生了令人鼓舞的结果。
