Abstract :

The present study was conducted on buffaloes that were non-cycling (heifers, n=32; lactating, n=13) or cycling (heifers, n=11; lactating, n=27) and in the buffaloes that conceived (heifers; n=11; lactating, n=23)or failed to conceive (heifers, n=32; lactating, n=17) subsequent to artificial insemination. Plasma samples were analyzed for thyroid stimulating hormone, thyroid hormones, glucose, total proteins, creatinine, blood urea nitrogen, total cholesterol and triglycerides. None of the plasma biochemicals were significantly different (P>0.05) between non-cycling or cycling and pregnant or non-pregnant buffaloes. However, non-cycling and non-pregnant lactating buffaloes had lower (P<0.05) plasma concentrations of thyroid stimulating hormone and thyroid hormones, respectively, compared to their counterparts. Thus, blood metabolite status is not the cause of differential fertility in buffaloes. However, a subtle thyroid activity in lactating buffaloes may have some impact on their fertility status.
