| ABSTRACT The objective of our study was to evaluate the effects of pineapple (Ananas comosus) leaf powder (PLP) on broiler performance. One hundred male broiler chicks (aged one day) were divided into five groups consisting of four pens as replicates, which were treated with basal diet (normal control); basal diet supplemented with 1, 2, and 3% PLP; or 50 mg/kg of zinc bacitracin (ZnB) as a positive control for 35 days. Body weights were significantly increased by 1.06, 5.67, 13.15, and 11.92%, respectively, and feed conversion ratios were decreased by 2.36, 8.49, 12.06, and 11.43%, respectively, in 1, 2, 3% PLP- and ZnB-supplemented groups, compared with the normal control group. Notably, the 2 and 3% PLP supplementations had beneficial effects on broiler... |
