Effect of Nano Zinc Supplementation on Haemato-Biochemical Profile in Assam Hill Goat

Abstract

The present study was aimed to evaluate the efficiency of nano zinc (NZn) as feed supplementation on haematological and biochemical profile of Assam Hill Goat. A total of 24 numbers of 7 days post kidding doe, 2nd to 3rd pariety maintained at Goat Research Station, Assam Agricultural University, Burnihat, India were used as experimental animal and divided into one control and three treatment groups each comprising 6 animals. Control group of animals were fed with basal diet without zinc supplementation, treatment 1 group with 25 mg NZn, treatment 2 group with 35 mg NZn and treatment 3 group with 50 mg NZn/kg concentrate mixture with basal diet for a period of three months. Blood was collected from each doe upto 3 months before treatment, fortnightly thereafter and on the day of oestrus. Results indicated that supplementation of nano zinc had no effect on haematological parameter. However, among other biochemical parameter studied, serum zinc level varied significantly (P<0.01) among the groups. The serum zinc level was found to be higher in NZn-50 mg as compared to control, NZn-25 and NZn-35 mg. Catalase and superoxide dismutase (SOD) activity were higher (P<0.01) in 25 mg and 35 mg NZn/kg concentrate mixture supplemented diets as compared to the group fed with 50 mg NZn/kg concentrate mixture and control. Serum progesterone level varied significantly (P<0.01) on day 84th of observations in T-2 and T-3 groups whereas serum estrogen level did not differ significantly among the group.
