| Popis: | Circulating FSH levels of 13 Murrah buffaloes were investigated by a double-antibody radioimmunoassay using a homologous bovine system. The mean (± s.e.m.) peak FSH level on the day of estrus was if57.94 ± 12.84 ng/ml of blood serum during hotter months (June–August) and 65.23±10.54 ng/ml during cooler months (October–December). These were much higher than the FSH concentrations recorded during the rest of the cycle post-mating. There were sizable fluctuations in FSH levels on different days of the estrous cycle within animals. However, the mean values did not exhibit much variation. The occurrence of the FSH peak and the LH peak coincided during the cycle. |
