贵妃鸡血液生化指标与体尺性状及屠宰性能的相关性

摘要

In order to understand the correlation,12 head of 14-week-old rare concubine chicken (6 male and 6 female)were randomly selected to measure the blood biochemical indexes,body size,and slaughter performance.The results showed that the average weight was 983.00g.There were highly significant positive correlation among γ-GT and ALT,LDH-L and CHOL,α-HBDH and LDH-L,ALP and shank girth,GLU and body length,GLU and breast muscle weight.And there were significantly positive correlation among CK and ALP, LDH-L and CHE,α-HBDH and CHOL,CHE and tibial circumference.While highly significant negative correlation showed between TG and keel length,and significant negative correlation showed among GLU and AST,ALT and body length,AST and breast muscle weight,γ-GT and body length.It could be concluded that all the biochemical indexes be used as genetic markers for productivity prediction and early stage breeding for concubine chicken.%为了解贵妃鸡血液生化指标及其与体尺性状、屠宰性能间的相关关系，随机选取12只（公母各半）14周龄贵妃鸡测定血液生化指标、体尺性状及屠宰性能并进行相关性分析。结果表明：14周龄贵妃鸡的平均体重为983．00 g，谷氨酰基转移酶与谷丙转氨酶、乳酸脱氢酶与总胆固醇、α-羟丁酸脱氢酶与乳酸脱氢酶、碱性磷酸酶与胫围、葡萄糖与体斜长、葡萄糖与胸肌重间均呈极显著正相关（P ＜0．01），肌酸激酶与碱性磷酸酶、乳酸脱氢酶与胆碱酯酶、α-羟丁酸脱氢酶与总胆固醇、胆碱酯酶与胫围间均呈显著正相关（P ＜0．05），甘油三酯与龙骨长呈极显著负相关（P ＜0．01），葡萄糖与谷草转氨酶、谷丙转氨酶与体斜长、谷草转氨酶与胸肌重、谷氨酰基转移酶与体斜长间均呈显著负相关（P ＜0．05），可将这些生化指标作为遗传标记以预测贵妃鸡的生产性能，进行贵妃鸡的早期选育。
