摘要: This study compared serum and follicular fluid inhibin gonadotropin profiles between chronic cystic ovarian diseased (CCOD) normal cyclic dairy cows. Blood samples were collected from CCOD cows (n=15) in the phase of estrous cycle (control, n=6) analyzed for inhibin, follicle stimulating hormone (FSH) luteinizing (LH) concentrations. There was a significant increase decrease FSH LH concentrations with those (P 0.05), however, there tendency to be higher lower animals < 0.1). The pulse frequency also than 0.05). These data suggest that increased production follicles alters pituitary secretion subsequently reduces concentration fluid. As result, decreased stimulation at level could ultimately lead reduction receptor concentrations, resulting abnormal steroidogenesis
