Abstract

This experimental study was carried out to assess the effect of condensed tannins (CT) through a leaf meal mixture of Ficus infectoria and Psidium guajava, on erythrocytic antioxidant status, immune response and gastrointestinal nematodes in lambs. Twenty-four non-descript lambs were randomly divided into four groups, consisting of six lambs in each, in a completely randomized block design, and randomly allocated to 4 dietary treatments: CT-0, CT-1, CT-1.5 and CT-2 containing 0, 1, 1.5 and 2.0 percent CT, respectively. The erythrocytic antioxidant status was monitored in all lambs at 0, 45, 90, 135, 180 days of feeding, however, humoral and cell mediated immune responses were determined at the end of the feeding trial. Hemoglobin was found to be highest (P<0.05) in CT-1.5 followed by CT-1, CT-2 and CT-0, respectively. CT supplementation significantly (P<0.05) improved the antioxidant status, as indicated by increased levels of glutathione peroxidase, catalase, reduced glutathione, glutathione-S-transferase, superoxide dismutase, total thiol and protein bound thiol group and decreased lipid peroxidase in the lambs. Supplementation of CT significantly (P<0.05) improved the cell mediated immune response in lambs. The fecal egg counts (FEC) in lambs were significantly (P<0.01) higher in the control group (CT-0), followed by CT-1, CT-1.5 and CT-2. The pooled fecal cultures of the lambs revealed that the majority of the infective larvae were from Haemonchus contortus. The FEC in the control was significantly higher (P<0.05) throughout the study period compared to the CT-1.5 and CT-2 groups. It may be concluded that dietary supplementation of CT (1-2%) through LMM improved the erythrocytic antioxidant status and immune response, and reduced FEC in lambs.
