| 摘 要： | 试验采用Ｈｅ－Ｎｅ激光穴位照射供体母牛，并结合纯化ＦＳＨ超排处理，以研究激光照射对牛超排效果的影响机理。结果表明：①Ｈｅ－Ｎｅ激光照射可提高牛超排效果，增加胚胎数和可用胚胎数，试验组头均胚胎数比对照组多２．２枚，头均可用胚胎数比对照组多１．９枚，差异显著（ｐ〈０．０５）；②Ｈｅ－Ｎｅ激光照射通过神经和体液调节，可显著提高血浆中ＦＳＨ（促卵泡素）水平，而ＦＳＨ水平升高是促使供体母牛卵泡发育，增加胚胎

| Abstract: | s Based on the purified FSH, the effect and mechanism of laser on cow super- ovulation was studied with the help of laser point irradiation. The results were as follows: atLaser irradiation could improve super ovulation, increase the number of embryos (EN ) and the number of embryos available(AEN ). The number of embryos of each cow (EN/) in the experimental group was 2. 2 more than that of control group w bile the average number of embryos available for each cow (AENs/) in the experimental group was 1. 9 more than that of the control group, with sharp difference (p<0. 05). @ The concentration of FSH in serum could be increased by nerve and humor adjustment through laser irradiation; while the increase of FSH was the direct factor for follicular development of cows supplying embryos, and for the increase of embryo number and the number of embryos available. |
