初乳的

For the first couple of days the breasts release colostrum, which is important to a baby's health

在开始产奶的前两天，乳房会生产初乳，初乳对婴儿的健康非常重要。

On, you can search about "Colostrum is the cows to drink," the article, is a very good article.

关于牛初乳，你可以搜索一下《牛初乳是给牛喝的》的文章，是一篇很好的文章。

Results showed that casein could be completely removed of by adjusting pH 4.6 and centrifuging at 1100g.β-lactoglobulin was absorbed by the cation-exchange resin eluented by phosphate buffer. Through limiting the quantity of acid whey, the purity concentration percent of immunoglobulin was above 80% determined by SDS-PAGE. The ratio of activity of immunoglobulin losing decreased in simulated pepsin and the residual immunoglobulin content percentage was about 80% in 60 minutes.

实验结果表明：调节脱脂牛初乳pH=4.6采用1100g低速离心即可达到完全去除酪蛋白的良好效果；利用含有磷酸根基团的缓冲液处理阳离子树脂柱会专一吸附酸性乳清中的β—乳球蛋白，达到分离乳清中免疫球蛋白与β—乳球蛋白的良好效果，控制乳清样品处理量可使免疫球蛋白纯度达到80%以上；微胶囊化的免疫球蛋白可以延缓胃液对免疫球蛋白的消化分解，减缓免疫球蛋白活性损失速率，在60分钟内仍可保留80%的活性。

Significant level of β-lactoglobulin was detected in the secretions 12d to 1d prior to parturition, Activities of γ-GT, NAGase, AKP in the secretions were generally higher than that of colostrum and milk, while lactoperoxidase activity was lower than that of milk.

在分娩前12d～1d的样品中均检测到β-乳球蛋白。分娩前乳腺分泌物中γ-GT、NAGase、AKP活力一般显著高于初乳和常乳，而LP活力显著低于常乳。

RESULTS (1) The content immuno-protein, addiment and protein in colostrure of premature delivery is more than that of term birth.

结果：1。早产初乳较足月产初乳含有更丰富的免疫球蛋白及补体，有利于提高早产儿的抗病能力；2。

GH concentration decreased to approximately the level in milk the second day of lactation, while PRL, INS, and IGF-Ⅰ maintained higher levels than in milk during the first several days at colostral period.

GH在泌乳第二天即下降至与常乳接近的水平，而PRL、INS和IGF-Ⅰ含量在初乳期前几天均保持较高水平。

An interview guide, entitled "Maternal Perception of the Onset of Lactation", was also used to obtain milk secretion data. Results found a mean onset of lactation of 78.2±18.7 hours (range=42 to 121 hours). The prevalence of delayed lactation onset was 43.6%(n=58). Slighly over half of participants (56.9%, n=33) were primiparous. Parity, total second stage of labor duration, duration of second labor stage beyond one hour, and perinea wound pain were the most significant predictors of delayed lactation onset.

研究结果发现：(1)首次泌乳时间的平均值为78.2±18.7小时（范围42至121小时）；(2)产妇自觉延迟泌乳的发生机率为43.6%(n=58)，其中初产妇占56.9%(n=33)，经产妇占43.1%(n=25)；(3)产次、第二产程时间、第二产程时间大於一小时、第一到第三天会阴伤口疼痛分数，是延迟首次泌乳时间的重要预测因子。

In this paper, by detecting on activity in bovine colostrum s in four days after calving, We have found the various law of activity in bovine colostrum , as well as the effects of freezing and low temperature long time pasteurizeing on it.

通过对产犊后前四天内牛初乳活性物质含量的检测，分析牛初乳中活性物质的变化规律及冻结、巴氏杀菌对其影响。

Early attempts at pasteurizing colostrum using the same time and temperature used in pasteurizing whole milk were largely unsuccessful due to the large reduction in immunoglobulin levels or the creation of a thick, pudding-like mass that was hard to feed and even harder to clean out of pasteurization equipment.

早期采用的初乳杀菌的方法是：采用与全脂牛奶巴氏杀菌的相同的时间和温度条件。但基本上不成功，这是由于初乳免疫球蛋白数量的大量减少，或形成了一厚厚的、布丁样的块状以致难以饲喂，甚至难以从巴氏杀菌设备中清除。

To purify high purity lactoferrin from bovine colostrums,a fast separation technique was established by ion-exchange process.

从牛初乳中分离提取乳铁蛋白，建立快速分离纯化乳铁蛋白的工艺。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
