生长期公母驴生产性能、血清生化指标、胴体性状和肉品质的比较
Comparison of Performance, Serum Biochemical Indices, Carcass Characteristics and Meat Quality of Male and Female Growing Donkeys
摘要
Abstract
This experiment was aimed to compared the difference in performance, serum biochemical indices, carcass characteristics and meat quality of male and female growing donkeys. Twenty 7 to 8?month?old im?proved Dezhou donkeys with similar body weight of (149.50 ± 7.20) kg and similar parity were selected, di?vided into 2 groups by sex, each group contained 2 replicates with 5 donkeys per replicate. The concentrate was feed based on the body weight of 1.5%, and soybean straw used as roughage, and the ratio of concentrate to roughage was 4∶6. The adaptation period lasted for 7 days and the formal period lasted for 270 days. The results showed as follows: 1) the dry matter intake and average daily gain of female donkeys were higher than those of male donkeys, but had no significant difference ( P>0.05) ; the body length, chest width, skinning rate and collagen content of female donkeys were significantly lower than those of male donkeys ( P<0.05 or P<0.01) , and the bust of female donkeys was significantly higher than that of male donkeys ( P<0.05).2) The serum al?bumin to globulin ratio of female donkeys was significantly higher than that of male donkeys ( P<0.05) , and the serum alkaline phosphatase activity of female donkeys was significantly lower than that of male donkeys ( P<0.01). There were no significant differences in other serum biochemical indices between female donkeys and male donkeys ( P>0.05). 3) The carcass rate, abdominal fat rate of female donkeys was significantly higher than that of male donkeys ( P<0.05) , and the shear force, marble rating and free fatty acid content in muscle of female donkeys was significantly higher than that of male donkeys ( P<0.01). There were no signifi?cant differences in other carcass characteristics and meat quality indices between female donkeys and male don?keys ( P>0.05). In conclusion, under the conditions of this experiment, the performance, carcass characteris?tics and meat quality of female donkeys are better than those of male donkeys, but the skinning rate and skin collagen content of male donkeys are higher than those of female donkeys.[ Chinese Journal of Animal Nutri?tion, 2019, 31(6) :2727?2734]关键词
