外源注射CART特异性dsRNA对蛋鸡产蛋性能和蛋品质的影响
Effects of exogenous injection specificity dsRNA of CART on production performance and egg quality for laying hen
摘要
Abstract
To investigate the effect of cocaine-and amphetamine-regulated transcript ( CART ) on production performance and egg quality of laying hen in laying period, 500 20-week-old healthy highland brown laying hens were randomized into 5 groups with 4 replications per group. Four treatments, which included no injection as the control ( group A) , and injections with CART specificity of double-stranded RNA ( dsRNA) on the 1st day ( group B) , every 40 d ( group C) , every 20 d ( group D) and every 10 d ( group E) , were applied after hens were fed for 30 d. Egg production performance, including egg quantity, quality, and composition, and body weight of hens were measured after 120-day treatment. Results showed that body weight and laying rate varied significantly a-mong treatment groups (P<0.05). All injected groups differed significantly from the control in average daily egg production (P<0.05) , except that no difference existed between group B and the control. Feed intakes of all injected groups were significantly high-er than the control ( P<0.05) , however, they were the same statistically among all injected groups. With regard to egg-feed ratio, all injected groups differed from the control ( P<0.05) , however, no difference existed among groups A, B and C, and between groups D and E. In a word, CART dsRNA exerts significant impacts on laying performance and body weight of laying hens but not on egg quality and components.关键词
