Abstract
The objective of this study was to evaluate the dietary supplementation of Phyllanthus niruri L. powder (meniran powder, MeP) on the productivity, haematology profiles, and intestinal morphology of broilers. A total of 200 female, one-day-old chickens were allocated to five treatments randomly, with four replications (10 birds per replicate): control, without antibiotic and MeP; T2, Zn-bacitracin 0.05%; T3, MeP 0.02%; T4, MeP 0.03%; and T5, MeP 0.05%. A completely randomized design was employed. The results showed that MeP supplementation at 0.02%, 0.03%, and 0.05% did not affect the body weight, feed intake, feed conversion ratio, haemoglobin, packed cell volume; and lymphocyte, red blood cell, heterophil, monocyte, eosinophil, and basophil counts, but at 0.03% and 0.05%, appeared to reduce white blood cells (WBCs) compared to those in the control and Zn-bacitracin groups. Microscopically, MeP supplementation in the diet increased the height and cellular growth of the mucosal villi of the duodenum, jejunum, and ileum, but the villi appeared fragile as mucosal epithelial cell necrosis was noted in the taller villi. Thus, it is concluded that MeP did not affect broiler performance and haematology profiles, except that the number of WBCs at 0.03% and 0.05% was less than that in the control and Zn-bacitracin groups
期刊介绍:
The South African Journal of Animal Science is an open access, peer-reviewed journal for
publication of original scientific articles and reviews in the field of animal science. The journal
publishes reports of research dealing with production of farmed animal species (cattle, sheep,
goats, pigs, horses, poultry and ostriches), as well as pertinent aspects of research on aquatic
and wildlife species. Disciplines covered nutrition, genetics, physiology, and production
systems. Systematic research on animal products, behaviour, and welfare are also invited.
Rigorous testing of well-specified hypotheses is expected.
