Aim: The present study was carried out to compare the associated role of micro minerals and hormones in repeat breeding animals with the normal crossbred cows.
Materials and Methods: Blood samples were collected from 10 normal cycling and 10 repeat breeding crossbred cows of Ramakrishna Mission Ashram, Narendrapur to study the plasma mineral profile and hormonal activities.
Results: Zn was found to be highly significant (p<0.01) between the two groups. Follicle stimulating hormone (FSH) and progesterone showed significant (p<0.05) difference in repeat breeding animal from the normal cyclic animal, whereas no significant differences were observed in Ca, P, Cu, Se, Co, luteinizing hormone and estradiol level.
Conclusion: It may conclude that repeat breeding condition of crossbred cows in farm condition is mainly due to the low level of progesterone, FSH and zinc.
Keywords: crossbred cow, hormone, mineral profile, normal cyclic, repeat breeding.
