| dc.description.abstract | Present investigation was carried out to find out the effect of vitamin D3 on milk production, circulatory hormones and plasma minerals in Murrah buffaloes. Twelve lactating healthy buffaloes were selected for the experiment and was divided as control and treatment group. All the buffaloes were maintained and fed as per the routine practices followed in the farm. The treatment group buffaloes received vitamin D3 dietary supplementation @ 20,000IU/day from 32-122 days of early lactation. Daily milk yield was recorded during experimental period from both the groups. Blood samples were collected at fortnightly interval and was analysed for plasma vitaminD3, PTH, Osteocalcin and IgG level. Milk production was significantly increased by vitamin D3 feeding in the treatment group (p<0.01) in comparison to control group. Milk yield increased by 1.99 kg/day in vitamin D3 supplemented buffaloes over the control group. Plasma vitamin D3 level and Osteocalcin levels were higher in the treatment group of buffaloes (p< 0.01) in comparison to control group. However plasma PTH level decreased significantly (p<0.01) in the treatment buffaloes. Plasma IgG level was significantly higher (p<0.01) in treatment group buffaloes as compared to control group buffaloes. Milk yield was positively correlated to circulatory vitamin D3 (p<0.01) and Osteocalcin (p<0.05) and was negatively correlated with PTH (p<0.01). Plasma Calcium concentration were significantly higher (p<0.01) in the treatment group of buffaloes as compared to control, however plasma Phosphorus were not influenced by treatment during experiment. Plasma Magnesium level were increased significantly (p<0.01) in the treatment group concomitant to increase in Calcium level as compared to control group of buffaloes. Plasma Calcium, Phosphorus and Magnesium level was non-significant during autumn and winter season in Tharparkar (TP), Sahiwal (SW) and Karan Fries (KF) cows. However, milk yield varied (p<0.05). It was concluded that vitamin D3 supplementation improved milk production and persistency of lactation due to increase in plasma vitamin D3 and Osteocalcin level in Murrah buffaloes. Supplementation also improves immunity of animals as indicated by positive impact of treatment on animal health. | |
