Abstract
|
|
|
|
The Purpose of this study was to determine the serum content of LH, FSH and prolactin. Blood samples collected from day 20 prepartum to 20 postrtum in 8 sows. LH, FSH and prolactin were assayed by radioimmunoassay methods. LH levels increased from 2.3 mIU/mell day 6 prepartum to 5.8 mIU/mell by day +2 and remained quite constant thereafter. The mean serum FSH increased from 7.5mIU/mell day 6 prepartum to 10.0 mIU/mell at the time of parturition, but the difference in LH and FSH patterns reported here provide further evidence that the controlling mechanisms for the two gonadotropins are independent. Prolactin reached a peak mean level of 68.5ng/mell at day 0.
