The present study was undertaken to ascertain the health-promoting effects of a phytoadditive (PA) having confirmed in vitro antimethanogenic potential. The PA was prepared by mixing fixed proportions of Withania somnifera, Boerhavia diffusa and Holarrhena antidysenterica. Eighteen Jamunapari kids of three months of age were used in a 180-day study. The kids were divided into three equal groups and supplemented with the PA at 0 (PA-0), 1.5 (PA-1.5) and 2.5 (PA-2.5) percent of expected mean daily feed (DM) intake. A metabolism trial conducted following 180-days of feeding trial indicated no variations (P > 0.05) in intake and digestibility of organic nutrients. The plane of nutrition and nitrogen retention was also similar (P > 0.05) across the treatments. Blood collected at 30-days intervals was assessed for erythrocytic antioxidants and metabolic indices. The PA improved (P < 0.05) the erythrocytic lipid peroxidation, and activities of superoxide dismutase, catalase and glutathione peroxidase. The serum levels of glucose, urea, total protein, globulin and alanine aminotransferase remained similar (P > 0.05) among the groups, whereas serum levels of albumin were improved (P < 0.05) in the PA-supplemented groups with a reverse trend (P < 0.05) for total cholesterol. The serum aspartate aminotransferase activity was reduced (P < 0.05) in both the PA-groups. The dietary treatments imparted no difference (P > 0.05) on the average daily gain (g) which was 35 ± 4.0, 31 ± 3.4 and 34 ± 4.0 for the PA-0, PA-1.5 and PA-2.5 groups, respectively. The feed conversion ratio was also comparable across the dietary groups. Overall, it is concluded that while the dietary supplementation of the PA had no influence on the nutrient metabolism or growth, it did stimulate the antioxidant status of growing kids and thus possess potential to be of practical value in stressful management situations.
