Relationship between Reproductive Hormone Levels and Fecundity in Timed Insemination during the Contemporaneous Rut of Sika Deer
Reproductive hormones are hormones produced by the hypothalamus,pituitary gland,gonads and placenta,which are directly related to reproductive functions.In order to explore the effects of reproductive hormone levels on the number of conceptions and fetuses in timed insemination during the same period of estrus in sika deer,40 sika deer were selected for this experiment and put into estrus at the same period of time by using vaginal suppository,and were inseminated at the same time of 58 h after the suppository was taken,and then the levels of reproductive hormones in the serum were detected and analyzed in the number of conceptions and fetuses in the serum after the timed insemination for comparative analysis.The results of the test showed that there were no significant differences in FSH,E2,LH and PRL in the serum of the nulliparous,singleton and twins groups(P＞0.05);the P changes were significant,and there was a highly significant difference between the nulliparous group and the conception group(P＜0.01).The results of the study concluded that serum P levels have an effect on pregnancy and conception in sika deer.The aim of this study was to explore the effects of reproductive hormone levels on the number of conceptions and pregnancies during timed insemination in the same period of estrus in sika deer,and to further identify the reproductive hormones that affect the number of conceptions and pregnancies in sika deer and to provide data to support them.
