At the end of lactation, the gland s return almost to their state before pregnancy.

在泌乳结束时，乳腺回复上几乎和怀孕之前一样的状态。

At the end of lactation, the glands return almost to their state before pregnancy.

在泌乳结束时，乳腺回复上几乎和怀孕之前一样的状态。

Sixty multiparity(parity 2or3),healthy dairy cows,which had the adjacent milk yield and body weight,and at 40-50 mean days in preterm.

选取泌乳量、体重差异不显著，胎次2-3胎，平均在预产期前40-50天，且健康无疾病的经产奶牛60头。

The relevant hormone determining results show: Prolactin, estradiol (E2) and progesterone content in serum have regularly changed during reproductive and nonreproductive phase.

相关激素测定的结果表明：血清中垂体泌乳素、雌二醇(E2)和孕酮含量在生殖期和非生殖期呈现规律性变化。

Methods Blood samples were collected from the precaval vein of 6 female Tibet mini-pigs to test the concentration of sex hormones including T,P4,E2,FSH,LH,PRL and blood biochemical indexes including Ca, Mg, P, ALP, Cre, CHO, TP, and Alb during the estrous cycle.

对6头雌性西藏小型猪在发情周期内的发情当天、第5天、第10天、第15天、再次发情时分别采血5 mL并分离血清，应用放射免疫法测定血清睾酮、孕酮(P4)、雌二醇(E2)、促卵泡生成激素、促黄体生成激素、泌乳素；用自动生化仪测定血清钙、镁、磷、碱性磷酸酶、肌苷、总胆固醇、总蛋白、白蛋白。

At present, the research about Heregulin-αand itsreceptors ErbB2 and ErbB3 was only the expression of them in mRNA and the impact ofHeregulin-αon the proliferation of mammary epithelial cells and milk proteins expression inculture. There were no results about the expression of Heregulin-αand its receptors in protein andthe impacts of Heregulin-αon the development, lactation and involution of mammary gland. It wasalso not clear about the signal transduction pathway of Heregulin-αin mammary gland.

目前对于乳腺中Heregulin-α及其受体ErbB2和ErbB3的研究仅限于其mRNA水平的表达以及Heregulin-α对培养的乳腺上皮细胞增殖和乳蛋白表达的影响，尚缺乏对乳腺中Heregulin-α及其受体在蛋白质水平上的表达变化规律以及Heregulin-α对乳腺发育、泌乳及退化的作用研究，正常乳腺中Heregulin-α的信号转导途径也不完全清楚。

ORION Group, Japan, which established in 1946, is the leader in making dairy machineries with a history of more than 60 years. At present, it occupies beyond 70% of the market share and has over 50 subsidiaries worldwide. The company owns the double-vacuum milking technology which currently leads the new trend in manufacturing the livestock machineries and meets the lactation features of high-yielding dairy cows. Besides, the ratio of pulses in front and rear udders demonstrates the most sophisticated milking technology.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
