In order to assess the effect of condensed tannins (CT) through tanniferous tree leaves on erythrocytic antioxidant status and GI nematodes, indigenous kids (n=18) were randomly divided into 3 groups of 6 each and fed iso-nitrogenous diets to contain 0 (CT-0), 1.0 (CT-1) and 2.0 (CT-2)% CT through a dried and ground leaf meal mixture of Ficus infectoria, Psidium guajava and Ficus bengalensis. Blood-biochemical profile and erythrocytic antioxidant status was monitored in all the kids at 0, 40, 80 and 120d of feeding. Supplementation of CT upto 2.0% of diet for 120d showed a significant (P0.001) improvement on the performance of kids. Total BW gain and ADG were higher (P0.001) in both CT supplemented groups than control. Feed conversion ratio was higher (P0.001) in CT-2 followed by CT-1 and CT-0, respectively. Haemoglobin, PCV, serum glucose, total protein were similar among the dietary treatments except for a reduction (P0.01) in serum urea level in CT-fed kids. There was improvement (P0.05) in erythrocytic antioxidant status n the CT supplemented groups evident from increased concentrations of superoxide dismutase, reduced glutathione, catalase and total thiol groups concomitant to a reduction in lipid peroxidation as compared to the control. Feeding of CT containing diets up to 2.0% level significantly (P0.05) decreased the faecal egg counts when compared with the control group. It may be concluded that a mixture of tree leaves (containing 12% CT) has the potential to improve antioxidant status with an apparent negative impact on GI nematodes in kids.
