摘  要:
为了探索山麻鸭有关血液生化指标与产蛋性能之间的关系,对该鸭品种的早期选择提供科学依据,测定分析了山麻鸭部分血液生化指标和产蛋数。结果表明,山麻鸭的总蛋白(TP)含量为(67.571±5.522)g/L,白蛋白(ALB)含量为(23.371±3.296)g/L,球蛋白(GLB)含量为(44.289±3.252)g/L,谷丙转氨酶(GPT)活性为(48.022±11.036)U/L,谷草转氨酶(GOT)活性为(37.622±21.895)U/L,谷氨酰转移酶(GGT)活性为(3.333±1.945)U/L,碱性磷酸酶(AKP)活性为(187.511±106.655)U/L,总胆固醇(CHOL)含量为(4.231±1.049)mmol/L,甘油三脂(TG)含量为(15.704±4.925)mmol/L,产蛋数(EP)为(100.040±8.166)枚。且山麻鸭的EP与TP、ALB、GLB、CHOL和TG存在极显著或显著相关(P<0.01或P<0.05)。同时,对山麻鸭产蛋数的选择,采用通径系数比相关系数要更加准确。根据产蛋数与生化指标之间的关系,采取向后淘汰法得到最优回归方程为:Y=-16.580X1+16.501X2+16.595X3+97.187,经F检验,其回归关系达显著水平(P<0.05),各偏回归系数也达显著水平(P<0.05),相关指数达到0.897。

摘  要:
In order to provide a scientific basis for early selection,the number of eggs and blood biochemical indexes were measured in Shanma duck.The results showed that the parameters were TP(67.571±5.522) g/L,ALB(23.371±3.296) g/L,GLB(44.289±3.252) g/L,GPT(48.022±11.036) U/L,GOT(37.622±21.895) U/L,GGT (3.333±1.945) U/L,AKP(187.511±106.655) U/L,CHOL(4.231±1.049) mmol/L,TG(15.704±4.925) mmol/L,EP (100.040±8.166),and the EP was significant correlation with TP,ALB,GLB,CHOL and TG(P < 0.01 or P < 0.05).The optimization regression equation of the number of eggs and blood biochemical indices was:Y =-16.580 X 1 +16.501 X 2 +16.595 X 3 +97.187.Their regression relation was significant (P < 0.05),the partial regression coefficient all so (P < 0.05),and the index of correlation was 0.897.
