摘要
为了评价葡萄渣经发酵处理后,应用于肉仔鸡的有效性和安全性,试验选用AA肉仔鸡40只,分为2组,每组20只,试验组饲喂含10%发酵葡萄渣的肉仔鸡配合饲料,对照组饲喂含5%棉粕和5%菜粕的肉仔鸡配合饲料,试验期为42 d。结果表明:与对照组相比,试验组日增重提高7.43%(P<0.05),料重比降低4.19%(P<0.05),死淘率为0;肤色、肌肉pH值、肌肉组织弹性、肌肉气味、器官湿重、清烹肉汤鉴定指标、品尝评价均无异常;试验组血红蛋白显著低于对照组(P<0.05),其余血液常规指标均无显著差异(P>0.05);试验组总胆红素、γ-谷氨酰氨转肽酶均极显著低于对照组(P<0.01),碱性磷酸酶、肌酐、尿酸显著低于对照组(P<0.05),其余血液生化指标均无显著差异(P>0.05);肌肉安全性方面:各组均未检测出有害微生物和有害寄生虫,所检测出的有害微量元素含量也都在国家标准规定值内,并远低于规定值,且试验组指标低于对照组。试验结果说明发酵葡萄渣应用于肉仔鸡是安全、有效的。
In order to evaluate the efficacy and safety of applying fermented grape slag in broiler chicken, 40 AA broiler chicken were selected and divided into two groups （20 broiler chicken in each group）. The broiler chicken in test group were fed with the compound feed containing 10% fermented grape slag and the broiler chicken in control group were fed with the compound feed containing 5% cottonseed meal and 5% rapeseed meal. The test lasted for 42 days. The results showed that the daily weight gain in test group increased by 7.43% than that in control group （P〈0.05）, the feed-gain ratio decreased by 4.19% than that in control group （P〈0.05） and the cull-and-death rate reached 0. The skin color, muscle pH, muscle flexibility, muscle smell, wet weight of organs, identification index of cooking broth and taste evaluation appeared normal. The haemoglobin content in test group was significantly lower than that in control group （P〈0.05）, and other indices in test group had no significant difference with control group （P〉0.05）. The contents of total bilirubin and ~/-glutamyl-transferase in test group were significantly lower than that in control group （P〈0.01）, alkaline phosphatase, creatinine and uric acid in test group were significantly lower than that in control group （P〈0.05）, other indices in test group had no significant difference with that in control group （P〉0.05）. As for the muscle safety, harmful microbes and harmful parasites were not detected in each group, the amount of harmful trace elements detected was within and greatly lower than the national standard specified value. And the amount of harmful trace elements in test was lower than that in control group, which indicated that it was effective and safe to apply fermented grape slag in the feed of broiler chicken.
