ABSTRACT

This study aims to investigate the effect of supplementing dietary cinnamon oil (CO) into broiler chicken diets on growth performance, carcass traits, haemato-biochemical parameters, immune function, antioxidant status, and caecal microbial count. Three hundred one-day old broilers were distributed randomly, with 5 replications, into 5 groups (12 birds per replicate). Dietary treatments comprised the basal diet (control group), and the basal diet supplemented by either 10 mg/kg avilamycin or 500, 1000 and 1500 mg/kg of CO. Results indicated that birds from CO-treated groups had higher body weight, weight gain and feed conversion ratio than the control group. Also, birds from CO supplemented groups had lower total cholesterol, triglycerides, lowdensity lipoproteins than those from the control group; the lowest values were recorded in the group treated with 500 mg/kg CO. Treatment with CO increased the relative weight of spleen, thymus, bursa of Fabricius and plasma content of IgM when compared to the control and the antibiotic-treated groups. In chickens fed CO a significant decrease in caecal total microbial count, total yeast and mold count, Escherichia coli, and Salmonella was noted in comparison with the control group but was similar to animals from antibiotic-treated group. The count of lactic acid bacteria increased in the caecum of chickens fed CO in comparison with those from the control group; the lowest level was observed in the antibiotic group. So, CO can be used in broiler chicken diets as a natural alternative to antibiotic growth promoters to improve gut health and consequently growth performance.

肉桂油对肉鸡生长、胴体性状、血液生化指标、免疫功能、抗氧化状态和盲肠微生物数量的影响

摘要：本研究旨在探讨肉桂油（cinnamon oil、CO）对肉鸡生长性能、胴体性状、血液生化参数、免疫功能、抗氧化状态和盲肠微生物计数的影响。将300只1日龄肉仔鸡随机分为5组（每个重复12只）。日粮处理包括基础日粮（对照组），基础日粮中添加10 mg/kg阿维拉霉素（抗生素组）和CO添加分别为500 mg/kg、1000 mg/kg 和1500 mg/kg 剂量组（CO组）。结果表明，与对照组相比，CO组的肉仔鸡具有更高的体重、增重和饲料转化率。此外，与对照组相比，CO组的肉仔鸡总胆固醇、甘油三酯、低密度脂蛋白较低；与对照组和抗生素治疗组相比，添加500 mg/kg 的CO组的上述参数值最低。添加CO增加了肉仔鸡脾脏、胸腺、法氏囊的相对重量和血浆IgM含量。与对照组相比，CO组的肉仔鸡盲肠微生物总数、酵母菌和霉菌总数、大肠杆菌和沙门氏菌显著减少，但与抗生素组相比结果相似。与对照组相比，CO组的肉仔鸡盲肠内乳酸菌数量增加；抗生素组最低。因此，肉桂油可以作为抗生素促生长添加剂的天然替代品用于肉鸡日粮中，以改善肠道健康，从而提高生长性能。
