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。

Abstract:

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=-16.580x1+16.501x2+16.595x3+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.
