Strategic Supplementation of Antioxidant Micronutrients in Peri-parturient Murrah Buffaloes Helps Augment the Udder Health and Milk Production.

The experiment was conducted to study the effect of supplementation of designer dietary antioxidant micronutrients on udder health, milk yield, and its quality in buffaloes under field conditions. Sixteen healthy multiparous advanced pregnant graded Murrah buffaloes (around the last 3 months of gestation), identical in body weights, parity, and feeding conditions, were selected for the study. Feed offered and residues left of an individual animal were measured and recorded for 7 consecutive days with the sampling of feeds being offered to buffaloes and analyzed for dry matter and trace minerals Zn, Cu, and Se. Carotene and vitamin E content of offered feed samples were calculated based on reported values. The calculation was made to determine the deficiency of above micronutrients, and an antioxidant micronutrient supplement was designed to take care of the deficient micronutrients and supplemented in half of the buffaloes (n = 8) considered to be a treatment, while remaining half (n = 8) is considered to be control, fed as per the existing practice of farmer without additional supplementation. This supplementation study was continued for 2 months during advanced pregnancy and thereafter for 3 months post-calving. Dry matter intake recorded weekly during the pre- and postpartum period of study remained comparable (P > 0.05) between two groups. Udder health monitored fortnightly by modified California mastitis test, milk pH and somatic cell count indicated improvement (P < 0.05) of strategic antioxidant micronutrients supplementation. Milk yield started showing improvement (P < 0.05) as early as the first week after starting lactation with throughout enhanced (P < 0.05) values of milk protein, fat percentage, and fat-corrected milk yield. It may be concluded that strategic antioxidant micronutrient supplementation (Zn, Cu, and vitamins A and E) in the ration of peri-parturient buffaloes not only improved the udder health by reducing the occurrence of mastitis but also increased the milk yield as well as fat and protein percentage of milk.
