Augmentation of postpartum reproductive efficiency in crossbred cattle by supplementation of ragi (Eleucine coracana) grain during transition period - a field study.

摘要

This study was undertaken to test the potency of ragi (finger millet) grain in augmenting the postpartum reproductive efficiency of crossbred cattle when fed during the first month postpartum (transition period). 21 crossbred cows in advanced stage of gestation were divided into 2 groups of 12 (treatment group additionally supplemented with ragi grain) and 9 (control group unsupplemented with ragi) animals each. A significantly positive correlation between the milk yield and day of conception was observed in the treatment group. Insignificant differences in the milk urea nitrogen (MUN) levels were observed between control and treatment groups. An inverse relationship of milk protein concentration and open days was observed in the control group, whereas a direct relationship was observed in the treatment group. Supplementation of ragi during the transition period advanced the onset of luteal activity and oestrus. It also reduced the open days, indicating that the feeding of ragi during the transition period could augment the postpartum reproductive efficiency in the crossbred cows under field conditions.
