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.
