METHODS: According to adherent + Thy1.1 antibody and complement-purification method, cranium was opened to expose olfactory bulb. Thereafter, two olfactory bulbs were obtained to remove cerebral pia mater, blood capillary, and peripheral tissues; additionally, olfactory nerve layer and olfactory bulb granular layer were sheared into 1-mm3 pieces for extract single-cell suspension. The cells were adjusted at the density of 1×107 /L and incubated with poly-l-lysine-coated culture bottle or culture plate in 5% CO2 incubator at 37 ℃. On the third day, cells were cultured with serum-free DMEM/F12 culture media.

The results showed that supplying lysine coated with the polyoxylateⅣand hydrogenated vegetable tallow in the rumen could significantly improve the concentration of plasma free lysine in the jugular vein (11.18ug/ml)(P＜0.05), which is about 66.61% of that with duodenal infusions of lysine(16.97ug/ml). The concentrations of free lysine were 7.31ug/ml and 8.00ug/ml with the basal diets and supplementing of Lys in the rumen respectively.

选用4头瘘管肉牛，采用4×4拉丁方设计，结果表明，瘤胃补充用丙烯酸树脂Ⅳ号和氢化植物油保护的赖氨酸26g(15g赖氨酸)，可显著提高肉牛血浆游离赖氨酸浓度(11.18ug／ml)，为十二指肠灌注15g赖氨酸(16.97ug／ml)的66.61％，基础日粮和瘤胃补充15g赖氨酸血浆游离赖氨酸浓度分别为7.31ug／ml，8.00ug／ml。

Alpha-1 antitrypsin is the most abundant circulating protease inhibitor in the body, Dr. Lomas said. Its most common deficiency mutation is the Z allele, where the amino acid lysine is exchanged for glutamic acid at position 342 in the polypeptide chain (Glu342Lys). About 1 in 1700 whites of northern European descent are homozygotes for this mutation and thus have plasma antitrypsin levels that are 10% to 15% below normal, he said.

Lomas博士表示，甲一型抗胰蛋白酵素是身体内最充分的循环蛋白酶抑制剂，最常见的缺损突变在Z对偶基因，该处的胺基酸 lysine与麸氨酸在多胜肽链的第342位置交换(Glu342Lys)；北欧血统白人每1，700人有1人是此一突变的同合子，因此血浆抗胰蛋白酵素值比正常低10%到15%。

Results Five hereditarily stable strains with high lysine production were obtained by four cycles of genome shuffling. A high lysine producing strain, F4-36, was obtained, which produced 16.95 g/dL lysine, 37.1% higher than that of the starting strain.

This experiment was designed to investigated the effect of energy and lysine content of thediet on maternal body gain, total number born, litter weight, serum biochemical indexes and hormone level, by means of saturation-D best regression design, so as to improve the reproductive performance of primiparous sow and offer theoretical basis for feeding during gestation.

本试验旨在研究日粮消化能(DE，Digestible Energy)和真可消化赖氨酸(TDLys，True Digestible Lysine)含量对初产母猪不同妊娠阶段母体增重、胎儿数、窝重、血液生化指标和激素水平等的影响，为提高初产母猪的繁殖性能以及在妊娠期进行合理饲喂提供理论依据。
