Animal Nutrition and Feed Technology

A feeding trial of two months duration was conducted on ten male kids, randomly divided into two equal groups. Group-I was supplemented with mineral mixture containing Mn, Cu and Zn which were deficient in their feeds. While group-II was un-supplemented control. Animals of both the groups were grazed eight hours daily, without any concentrate supplementation. Hematological parameters and trace mineral status of blood in animals of supplemented and un-supplemented groups were estimated. The hematological values were within the normal range in both the groups before and after the experiment. Mineral supplementation significantly (P<0.01) improved the hemoglobin concentration and Packed cell volume. There was significant (P<0.05) improvement mean corpuscular volume, mean corpuscular hemoglobin concentration values in the supplemented group after the experiment. Status of Mn, Cu and Zn in blood was within the normal range in both the groups. The concentration of trace minerals in plasma tended to increase upon supplementation.
