The purpose was to search the change level of reproductive hormones in cage-fed female Crab-eating Macaque after copulation in Guangxi.

［目的］探讨广西地区笼养雌性食蟹猴配种后生殖激素的变化水平。

ResultThe results indicated that after copulation of Crab-eating Macaque from 1 to 60 day, the content of P declined slowly, reached the lowest level in the 60th day which was (0.22±0.06) ng/ml, and then rised up slowly to a big peak value of (1.15±0.12) ng/ml in the 105th day, after that, the concentration decreased gradually, the average was (0.66±0.08) ng/ml.

结果］结果表明，在配种后160 d孕酮的含量缓慢降低，第60天降到最低水平(0.22±0.06)ng/ml，其后缓慢上升，第105天出现一个大的峰值，为(1.15±0.12)ng/ml，峰值过后浓度呈下降趋势，整个测定时期的平均值为(0.66±0.08)ng/ml。

The radioactivity immune analysis was adopted to determine serum extradio-E2 (E2), progesterone and prolaction in Crab-eating Macaque after copulation.

方法］采用放射免疫分析法测定食蟹猴配种后血清雌二醇(E2)、孕酮和催乳素的水平变化。

Gilts were slaughtered on day 12, 25 and 35 of pregnancy, and serum, uterine flushings, embryos and endometria were collected. ELISA was adopted to determine the progesterone concentration in serum and uterine flushings, and RT-PCR was adopted to determine the genes expression in embryos and endometria.

母猪配种后随机分到3个组，按2.0倍、1.2倍和0.6倍维持需要供给饲粮（分别为采食高、中、低水平），妊娠12、25和35d屠宰母猪，收集血清、子宫液和胚胎、子宫组织，运用ELISA测定血清和子宫液中孕酮浓度，用RT-PCR测定目的基因在胚胎和子宫内膜中的表达。

Half-sib mating was used and one boar and five gilts were raised in a mating pen. Numbers of born alive per litter produced by G1 sows at 1.0, 1.5 and 2.0 years of age were 1.82+2.47 (N=36), 3.02+2.56 (N=30) and 5.02+2.26 (N=34) piglets, respectively.

再进行1公5母的半同胞并栏配种，第一代种母猪的分娩年龄为1.0、1.5和2.0岁时，其每胎活仔数分别为1.82±2.47(36胎)、3.02±2.56(30胎)和5.02±2.26头(34胎)。

In this study, we established the specialized raising model of reserved heifers, which can make weaning and mating earlier, decreasing the cost of feeding and management, increasing the quality of the whole cattle and the technique level of production management, and raising the returns of the specialized raising farm of reserved heifers.

本研究建立了后备牛专业化饲养的养殖模式，该模式的研究实施，使受试牛群犊牛断奶时间提前、育成牛配种时间提前，降低了转群成本和饲养管理费用，提高了奶牛场牛群整体水平与生产管理技术水平，并可使后备牛专业化饲养场的效益明显增加。
