Dairy cows undergo dramatic changes in physiological, biochemical and metabolic homeostatic mechanisms during the transition period leading to stress and negative energy balance to the animal which in turn leads to decreased fertility. The objective of the current study was to evaluate the effect of supplementation of fermented yeast culture (FYC) on the metabolic profile and reproductive parameters of healthy t Murrah buffaloes during the transition period. Fourteen Murrah buffaloes with no history of reproductive problems under field conditions were selected and divided into two blocks (supplemented group and control group) based on yield, parity, body condition score, and predicted calving date. In the supplemented group, each animal was supplemented with 24 g/day FYC mixed in concentrate from −15th day pre-partum to 90th day post-partum in addition to basal ration. Energy balance of animals was assessed by estimation of blood metabolites (glucose, non-esterified fatty acids[NEFA], beta-hydroxybutyric acid [BHBA]), plasma lipid profile, viz., cholesterol, HDL, VLDL, and triglycerides at 15 days interval. Post-partum fertility was assessed to determine the onset of first post-partum heat, number of inseminations per conception, conception rate, and service period. Significantly higher plasma levels of glucose (p < 0.05) were observed in the supplemented group compared to the control at 45th, 60th, and 90th day post-partum, thus indicating positive effects on glucose level by FYC supplementation. Significantly (p < 0.05) lower levels of NEFA were observed in the supplemented group at 15th and 75th day post-partum than the control group. Significantly lower (p < 0.05) plasma levels of BHBA were observed in the supplemented group from 15th day post-partum till the end of experimental trial than in the control group. The supplemented group showed improved conception rate of the order of more than 10% compared to the control group. The service period was significantly (p < 0.05) less in the supplemented group (117.25 ± 4.81 days) in comparison to the control group (146.25 ± 4.81days). Overall post-partum conception rate was 85% in the supplemented group and 72.52% in the control group. [ABSTRACT FROM AUTHOR] |
