Haemodynamic Changes of the Superovulated Follicle as a Cause of Superovulation Variability in Cattle

The aim of this study was to explore the real time changes in the vascularity of growing superovulated follicles and to establish whether the blood flow of growing follicles can affect superovulation… (More)

The effect of parity on the efficacy of ovulation synchronization ( Ovsynch ) protocol in buffalo ( Bubalus bubalis )

The aim of the present study was to study the effect of parity on the efficacy of Ovsynch protocol in buffalo. Out of 686 buffalo heifers (HE) and 273 cows (BC), 8 heifers and 9 cows were used to… (More)
