ABSTRACT
Vanadium (V) has not been elucidated as an essential mineral in ruminants, though in lower organisms and rat model, its role is well known as insulin-a mimetic agent for catalyzing enzymatic activities. The objective of this study was to determine the effect of V supplementation on production performance, milk composition, and mineral profile in lactating goats. Twenty-four crossbred goats (body weight 34.83 ± 0.25 kg) were blocked in four groups and randomly assigned to four treatment groups (n = 6) on body weight and milk yield basis. All the animals were kept on similar feeding regimen except that different treatment groups were supplemented with 0, 2, 4, and 6 ppm inorganic V/kg DM. Feed intake, milk yield, milk composition, nutrient utilization, minerals in plasma and milk, and their balance studies post vanadium supplementation were observed during the 150-day experimental period. V supplementation did not change dry matter intake (DMI), milk yield, and composition during the experimental period. Calcium levels in plasma were improved (P < 0.05) on vanadium supplementation. Nutrient digestibility remained similar among goats fed on basal or V-supplemented diets. Blood and milk V concentration showed a positive correlation with supplemental V levels but no difference was observed in levels of other minerals. The results of present findings indicated that up to the supplemented level, dietary inorganic V does not affect the production and mineral profile in milk and plasma.
