Abstract

Highlights • The effects of dietary supplementation of three Bangladeshi traditional medicinal plants (TMP) were evaluated on growth performance, digestibility of nutrients, hematological indices, immune index and antioxidant status in post-weaned bull calves. • Feed supplementation with TMP enhanced health indices such as augmentation of monocyte, platelet percentage, IgG and lymphocyte proliferation whereas a reduction of IGF was recorded. • An elevated level of TNF-α, total antioxidant and glutathione peroxidase activities were found in calves treated with medicinal herbs.
