Variations in hypophyseal responsiveness to synthetic GnRH-induced LH release and reproductive performance in dairy buffaloes with luteal activity during early postpartum period

Elevated luteal activity immediately following parturition reduces the reproductive performance in terms of prolonged anestrus that results in serious economic constraints to buffalo breeders. The present study was undertaken with the objective to investigate the changes in pituitary responsiveness...

Description
Summary:Elevated luteal activity immediately following parturition reduces the reproductive performance in terms of prolonged anestrus that results in serious economic constraints to buffalo breeders. The present study was undertaken with the objective to investigate the changes in pituitary responsiveness to synthetic GnRH in 15 lactating buffaloes at 25_35 days post-partum. On the basis of progesterone profile for at least 2 consecutive samples, they were categorized into 2 groups i.e. with elevated luteal activity (plasma P4 1.0 ng/ml; n = 9) and reduced luteal activity (plasma P4 1.0 ng/ ml; n
