A single-factor experiment was designed to research the effect of nutrition level on body weight of multiparous sows during gestation through investigating the effect of gestation nutrition on the reproduction performance of multiparous sows in subsequent 3 parities and based on regression analysis of feed intake as well as lactation weight loss and reproduction performance during gestation.

Eight healthy multiparous Chinese Holstein cows in early lactation were chosen. There were four high-yielding cows and four middle-yielding cows, separately with similar milk yield, parity and parturition date and body weight.

选择8头经产泌乳早期的中国荷斯坦奶牛，其中4头中产奶牛和4头高产奶牛(健康无病，中产奶牛和高产奶牛分别具有相近的产奶量、胎次、产犊日期和体重)，分别采用4×4拉丁方试验设计进行试验，研究日粮中补充染料木黄酮对奶牛的影响。

Experiment of the third part use the first part"s production as carrier, selecting Geotrich candidum and Candida tropicalis of higher production of protein also selecting producing the cellulose enzyme Bacillus subtilis FS and Lactobacillus bulgaricus by ourselves separated, design orthogonal test and a series of single factor experiment, finally assurancing the inoculation quantity of four strains germ, is Geotrich candidum 5%, Candida tropicalis 5%,Bacillus subtilis FS 5% of FS, Lactobacillus bulgaricus 3%, the most suitable development temperature is 30 "C , the development time is 15 days.

实验的第三部分是以第一步共培养所得的培养物为载体，选择产蛋白量高的白地霉、热带假丝酵母及本室筛选的产纤维素酶芽孢杆菌FS和自行分离的保加利亚乳酸杆菌，设计正交实验和一系列单因素实验，最终确定了四株菌的接种量，分别为白地霉5%，热带假丝酵母5%，FS5%，保加利亚乳杆菌3%，最适培养温度为30℃，培养时间为15天。

Based on the results of the previous Plackett-Burman design, four key factors was chosen, namely fermentation time, whey powder, saccharose and sodium acetate.

在使用Plackett-Burman设计试验的基础上，筛选出发酵时间、乳清粉、蔗糖和乙酸钠为鼠李糖乳杆菌Ls-8菌株发酵产抑真菌活性物质的4个关键影响因子。

METHODS The level of immuno-protein, addiment (C3 and C4) and protein in colostrum for 60 mothers are tested by single dimensionaldoffusion and binret test.

应用单向扩散法和双缩脲法分别测定30例早产产妇初乳和30例足月产产妇初乳中免疫球蛋白sIgA、IgA、IgG、IgM、补体C3、C4和蛋白含量。

Compared with the Giant panda in captivity, the predominantintestinal florae of Giant panda returned to wild were still enterobacteria(Escherichia coli, Enterobacter aerogenes, Proteus, Salmonella, Yersinia enterocolitica), enterococcus and lactobacillus after Giant Panda had been returned to wild for a week.

与圈养大熊猫相比，放归大熊猫在放归一周后，肠道正常菌群中优势菌群仍为肠杆菌(大肠杆菌、产气肠杆菌、变形杆菌、沙门氏菌、小肠结肠炎耶尔森氏菌)，肠球菌和乳杆菌，但细菌数量即开始发生了一定变化，表现在肠球菌数量明显增加，乳杆菌数量明显减少，肠杆菌数量有轻微减少，到采样后期，肠球菌数量超过肠杆菌；另外，放归大熊猫粪样中芽抱杆菌和酵母菌的检出率较高，分别为60%和40%。

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。

To carry out the process, one usually inoculate s milk with the desired starter culture, incubates it at, optimum temperature, and then stops microbial growth by cool, Lactobacillus spp.

这个生产过程中，人们通常是将发酵剂接种于乳中，然后在最佳温度进行培养，最后通过冷却终止微生物的生长，用乳酸杆菌和乳链球菌产酸。

As the problem in low concentration SO_2 exhaust disposal processes through spraying milk of lime in environment protection plant of Lead and Tin metallurgy factory,the technology reform has been done.

针对铅锑冶炼厂环保车间石灰乳喷淋处理低浓度SO2烟气存在的问题，对环保车间进行了技术改造，采用碳酸氢氨水溶液代替石灰乳喷淋处理低浓度SO2烟气，副产亚硫酸氨产品，取得了良好的效果。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
