摘要

本试验旨在研究在玉米-大豆基础饲粮中添加木瓜叶提取物(PLES)对0 ~ 37日龄肉仔鸡生长性能、胴体特性、肉品质和血清生化指标的影响。选取520只1日龄未性别科布-500肉鸡,随机分为5个处理组,每组4个重复,每组26只鸡。各处理组分别在1000 ml饮用水中添加0.00、0.5、1.00、1.5、2.00 cc的PLES。分别于0 ~ 11日龄、12 ~ 26日龄和27 ~ 37日龄饲喂预发酵剂、发酵剂和生长饲料。试验37 d,测定体重、增重、采食量、饲料系数和肉鸡生产效率系数(BPEF)。测定胴体、肉质和血清生化指标。本研究结果表明,各试验组肉鸡体重、增重和肉鸡生产效率系数均不显著高于对照组。各处理组肉鸡采食量和饲料系数无显著差异。鸡胸肉的屠宰特性和肉质的相对比例(滴水损失、蒸煮损失)在不同处理之间没有显著变化。然而,治疗组血清总胆固醇比对照组有降低的趋势(P<0.10),但其他指标(白蛋白、总蛋白、高密度脂蛋白)不受治疗组的影响。综上所述,在饮用水中添加木瓜叶提取物可作为植物添加剂促进肉鸡生长,改善肉鸡健康状况,且无不良反应。

Effect of papaya leaf extract on growth performance, carcass characteristics, meat quality and serum biochemistry of broiler chickens
This study was conducted to investigate the effect of supplementing papaya leaf extract (PLES) in drinking water on growth performance, carcass characteristics, meat quality and serum biochemistry parameters of broiler chickens from 0 to 37 days of age in corn-soybean based diet. A total of 520 unsexed one-day-old Cobb-500 broiler chicks were randomly assigned to five treatment groups, with four replicates having twenty-six chicks in each group. Treatment groups were as follows: 0.00, 0.5, 1.00, 1.5 and 2.00 cc of PLES in 1000 ml of drinking water, respectively. The pre-starter, starter and grower diet were fed from 0 to 11, 12 to 26 and 27 to 37 days of age. Body weight, weight gain, feed intake, feed conversion ratio and broiler production efficiency factor (BPEF) were measured for 37 days. Carcass, meat quality and serum biochemical parameters were also measured. The results of the present study showed that non-significantly greater body weight, weight gain and broiler production efficiency factor (BPEF) were observed in PLES groups than control. There was no significant difference in feed intake and feed conversion ratio of broiler chickens in the treatment groups. The relative proportion of dressing characteristics and meat quality in terms of drip loss, cooking loss of breast meat did not alter significantly between the treatments. However, total cholesterol in serum tended (P<0.10) to be reduced in the treated groups than control but other (albumin, total protein, high-density lipoprotein) were not influenced by the treatments. Taken together, our results indicate that papaya leaf extract in drinking water can be supplemented as phytobiotic additive to accelerate growth and improve health status of broiler chickens without any adverse effect.
