This study was conducted to determine the effects of powder as a dietary supplement on the growth performance, gut morphology, serum concentration of IgG, and the hematology parameters of broiler rabbits. A total of 32 rabbits [New Zealand × Californian] were weaned at 35 days. They were randomly selected for two dietary treatments (eight repetitions per treatment), which consisted of a basal diet and a basal diet supplemented with 1.5% dried-stem powder of . On day 60 from the initiation of treatment, gut histomorphology (duodenum and cecum), serum concentration of IgG, and hematology parameters were all measured. The results showed that powder supplementation improved ( < 0.05) the ADFI, ADG, and final BW. Correspondingly, this treatment increased ( < 0.05) the muscle and mucosa thickness and height and width of villi. However, duodenum crypts depth was lower ( < 0.05) when rabbits were fed with this natural product, compared with the basal diet treatment. Results also indicated that the powder increased ( < 0.05) the serum concentration of IgG but did not change the hematology parameters. This data indicates that powder, as a supplement, had beneficial effects on increasing the growth performance and serum concentration of IgG, as well as improving the gut morphology without affecting the hematology parameters in broiler rabbits.
本研究旨在确定[某种植物名称]粉末作为一种膳食补充剂对肉兔生长性能、肠道形态、血清IgG浓度和血液学参数的影响。总共32只[新西兰×加利福尼亚]肉兔在35日龄时断奶。它们被随机分为两种日粮处理组（每组处理重复8次），分别为基础日粮组和添加1.5%[某种植物名称]干燥茎粉末的基础日粮组。在处理开始后的第60天，测量肠道组织形态学（十二指肠和盲肠）、血清IgG浓度和血液学参数。结果表明，添加[某种植物名称]粉末提高了（P<0.05）平均日采食量（ADFI）、平均日增重（ADG）和末重。相应地，该处理增加了（P<0.05）肌肉和黏膜厚度以及绒毛的高度和宽度。然而，与基础日粮处理相比，用这种天然产物饲喂肉兔时十二指肠隐窝深度较低（P<0.05）。结果还表明，[某种植物名称]粉末增加了（P<0.05）血清IgG浓度，但未改变血液学参数。这些数据表明，[某种植物名称]粉末作为一种补充剂，对提高肉兔的生长性能和血清IgG浓度以及改善肠道形态具有有益作用，且不影响肉兔的血液学参数。
