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。

Suckled yak in parturition year had very low of oestrus rate which led to very low reproduction rate.

产犊牦母牛当年发情率很低，直接影响了牦牛的繁殖率。

If the ingredients other than corn and oats are pelleted ,this can an excellent starter.

如果能够对日粮中除玉米和燕麦的其他成分进行制粒处理，那将是非常好的犊牛料。

Fines in pelleted calf starter can also depress intake.

如果颗粒料中有粉末，同样也可以降低犊牛的采食量。

In trial 2, according to the similarity of calving date and milk yields, 25 primiparous Holstein cows were divided into five equal groups in a randomized block design with 49 days period. The general diet of dairy farm was fed to cows of control. The alfalfa block 2.7kgd^(-1 was substituted respectively by rice straw block Ⅰ,Ⅱ,Ⅲ or Ⅳ as treatments.

试验2，选取25头初产荷斯坦泌乳母牛采用随机区组设计按产犊日期、产奶量一致原则等分为5组，对照组用奶牛场常规日粮饲喂，试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别用稻草块Ⅰ、Ⅱ、Ⅲ、Ⅳ等量替代苜蓿草块，每头替代量为2.7kgd^(-1)，试验期49d。

Calf starter is a crucial link to proper ruminal development and successfully weaning.

犊牛料与瘤胃的正常发育和成功断奶密切相关。

Under our conditions, detection rate of embryonic DNA were zero with 2 cells, 62.5% with 4 cells, 90% with 8 cells and 100% with 16 cells. A total of 23 embryos that had been biopsied and sexed were transferred into the donor...

对 2 3枚经过性别鉴定后的胚胎进行移植，获得 5头纯种试管牛，产犊率为 2 1 7%，与正常的胚胎移植结果 2 7 3%( 3 1 1 )无显著差异，预测性比为 1 0 0 %符合。

The calf intestinal epithelial cells in vitro were selected to evaluate the trophic actions of insulin, IGF-J and peptic and tryptic hydrolysates of bovine colostrum. The cell proliferation, glucose absorption and specific activity of cell membrane enzymes were investigated.

为研究乳源性生长因子对动物胃肠道生长发育的作用，本试验以离体犊牛小肠上皮细胞为试验对象，研究了胰岛素、胰岛素样生长因子Ⅰ和酶解牛初乳对细胞增殖、葡萄糖吸收和细胞膜酶活性的影响。

The optimization techniques to adjust and control stocking rate were as follows: firstly, a quantity of beef cattle should be eliminated through selection or sell before damp off of pasture; secondly, a quantity of rotational grazing districts should be left to be utilized for winter and spring during pasture growth midseason.

18.6 调控载畜量的优化技术是：第一，枯草期前淘汰部分牛只，减少冬春载畜量；第二，在牧草生长旺季，留下部分轮牧区作冬春放牧草地；第三，通过刈制干草、青贮饲料将6—8月牧草生长高峰期的过剩牧草储备或转移到翌年3—5月产犊期利用。

SCS of calving season was low in spring and winter, but high in summer andautumn.

牛场、胎次和产犊季节对奶牛产奶量影响的差异极显著(P＜0.01)。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
