Institute of Animal Science and Veterinary Medicine, Zhejiang Academy of Agricultural Sciences, Hangzhou 310021; 3. College of Animal Sciences, Zhejiang University, Hangzhou 310029,China)  
This paper analysis of variance and estimation of least squares means based on the data of 125 ducks laying performances (total eggs of 300 days , total egg weight of 300 days, the average egg weight). The result indicated that the influence of the fixed effects of body weight and location on the 3 traits of laying, glutamate Glutamat-Pyruvat-Transferase(GPT)on Total egg weight of 300 days and the average egg weight, total protein(TP) on the average egg weight are all highly significant(P 0.01). The effect of GPT on total eggs of 300 days and TP on total egg weight of 300 days are significant(P 0.05). The deciding coefficient of 3 traits of laying are as follows: 0.58, 0.75, 0.84.
