- Abstract
This study was conducted to evaluate the effect of different levels of inorganic chromium (Cr) on nutrient intake, nutrient utilization, milk mineral contents, and blood biochemical in lactating Murrah buffaloes. Twenty-four multifarious Murrah buffaloes were blocked into four groups having six animals in each group and fed for 150 days post-partum. Feeding regimen was same in all the groups except that treatment groups were supplemented with 0.0, 0.5, 1.0, and 1.5 mg inorganic Cr/kg dry matter (DM) in the four respective groups. Group fed on basal diet supplemented with 0.0 mg Cr/kg DM served as a control. Adding inorganic Cr to the diet of lactating buffaloes increased feed intake, milk yield, and nutrient digestibility. Nitrogen (N) and Cr balance were significantly increased ( P < 0.05) by adding Cr. Milk and plasma Cr concentration could be increased by adding Cr ( P < 0.001), while no significant differences were found between the four treatments in milk and plasma concentration of calcium (Ca), copper (Cu), and zinc (Zn). Feeding of diet supplemented with inorganic Cr decreased plasma insulin concentration ( P = 0.016). Concentration of blood glucose and the ratio of blood glucose to insulin were increased by adding Cr ( P = 0.037 and P = 0.011, respectively). Adding Cr to the diet of lactating buffaloes did not show any effect on blood hemoglobin (Hb), while plasma concentration of progesterone and antioxidant status was increased ( P < 0.05). It could be concluded that adding Cr to the diet of lactating buffaloes improved nutrient intake, nutrient utilization, and lactation performance.
