The testing methods and targets were shown as below:Recorded milk weights from the 7th day postpartum to 15th day postpartum,and calculate the average day-milk yield;Milk samples were draw in 7th day and 14th day postpartum,and testing the milk fat,milk lactose,milk protein,milk Zn and the milk somatic cell counts;Blood samples were adopted at the 7th day postpartum,testing the levels of serum PRL; Blood samples adopted at the 1st day and the 12th day in oestrous cycle were used to test the levels of E_2 and P_4 in serum;In the experimental stage, registering the condition of parturition, the mean birth weight of calves,the first oestrus,the oestrus scycle postpartum and the conception rate of the first service after artificial insemination.

试验方法及所测指标如下：于产后第七天到第十四天记录日产奶量，最后计算每组平均日产奶量；每组随机抽取分娩后第七天、第十四天的奶样，测定乳糖、乳蛋白、乳脂、乳锌含量及乳体细胞数；于产后第七天，随机采取奶牛血样，测定血清中PRL含量；于发情周期的当天和第12天，随机采取血样，测定血清中雌二醇(Estradiol，E2)和孕酮(Progesterone，P)的浓度；记录奶牛的分娩情况、犊牛初生重、产后第一次发情日期、产后发情周期，并采用人工授精技术进行受精，记录第一情期受胎率，最后取平均值，作为衡量奶牛繁殖性能的指标。
