摘　　要：该试验旨在研究复合微生态制剂对清远麻鸡生长性能、肉品质和风味品尝的影响。选用150只60日龄健康发育良好的清远麻鸡(公、母各半),按照体重一致原则随机分为3个处理组,每处理5个重复,每重复10只鸡,基础饲粮中分别添加0(对照组)、300 mg/kg、600 mg/kg的复合微生态制剂。试验鸡自由采食和饮水,试验期共60天。试验结果显示,饲粮添加复合微生态制剂对清远麻鸡的生长性能无显著影响(P>0.05)。与对照组相比,300 mg/kg、600 mg/kg微生态制剂组平均日增重分别高1.06%和1.59%。与对照组相比,300 mg/kg复合微生态制剂组腿肌蒸煮损失显著降低并显著提高胸肌肉色的a^(*)值(P<0.05)。与对照组相比,300 mg/kg复合微生态制剂组的胸肌多汁性显著提高(P<0.05)。综合以上试验结果表明饲粮添加300 mg/kg复合微生态制剂可以减少肌肉的蒸煮损失,提高胸肌肉色的a^(*)值(红度值)和多汁性,对生长性能无负面影响,说明复合微生态制剂对清远麻鸡的肉品质有改善作用。This experiment was conducted to study the effects of compoundmicroecological preparation(CMP)s on growth performance,meat quality and flavor taste of Qingyuanmabroilers.A total of 150 healthy and well-developed 60-day-old Qingyuan Ma broilers(half male and half female)were randomly divided into 3 treatment groups according to the principle of consistent body weight,with 5 replicates per treatment and 10 chickens per replicate.The basal diets were supplemented with 0(control group),300 mg/kg and 600 mg/kg CMP,respectively.The experimental chickens were fed and watered freely for 60 days.The results showed that dietary CMP had no significant effect on growth performance of Qingyuan Ma broilers(P>0.05).Compared with the control group,the average daily gain of 300 mg/kg and 600 mg/kg CMP groups was 1.06%and 1.59%higher,respectively.Compared with the control group,the cooking loss of leg muscle in 300 mg/kg CMP group was significantly decreased,and the a^(*)value of chest muscle color was significantly increased(P<0.05).Compared with the control group,the juiciness of pectoral muscle in 300 mg/kg CMP group was significantly increased(P<0.05).In conclusion,dietary 300 mg/kg CMP can reduce the cooking loss of muscle,improve the redness value and juiciness of chest muscle color,and have no negative effects on growth performance,suggesting that CMP can improve the meat quality of Qingyuan Ma broilers to some extent.
