Injection of FSH and HCG to the anestrous female minks may induce the animals to come into an estrus state.On the 11th day of treating with FSH+HCG and on the 7th day of treating with HCG alone,the animals were observed to express the signs of sexual excitement:the serum level of progesterone increased and that of estradiol declined.At that time,the follicles developed into the mature state;the uterus became hypertrophied;the wall of vagina turned thickened;there were cornified epithelial cells in the vaginal smears.The signs mentioned above were quite similar to those of sexual excitement which occured in estrous minks in their breeding season.\; 水貂 休情期 发情 生育力 mink anestrus estrus fertility Q492 湖北省科委基金 1999-06-01 2021-04-01 6
