PLASMA LEUTINIZING HORMONE PROFILING IN NORMAL AND REPEAT BREEDING KANKREJ COW

摘要

The present investigation on plasma leutinizing hormone (LH) profile of 12 Kankrej cow (6 normal and 6 repeat breeding) was carried out on the day of estrus. The mean plasma LH concentration at 2 hours intervals from 8 hours to 36 hours post estrus was significantly (p<0.05) higher in control as compared to repeat breeder group at all the period of sampling except during first two collection where nonsignificant higher level was observed. Further, in control group the level of plasma LH was increasedfrom 8 hrs. after onset of estrus and reached a peak level at 20 hours (4.62 ± 0.52 mlU/mL) and thereafter it declined. Whereas, no such trend was observed in repeat breeder group.
