ABSTRACT This research aimed to evaluate the influence of a commercial prebiotic in different concentrations upon several parameters. To carry out the experiment, 640 male one-day-old broiler chicks were distributed in four treatments (0, 0.5, 1.0, and 1.5 kg/ton of yeast cell wall) with eight replicates of 20 birds per experimental unit, in randomized blocks. Prebiotic effects were assessed on performance, carcass yield and prime cuts, in addition to the litter quality (its content of nitrogen and phosphorus). There were […]

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, […]

Four hundred male Cobb chicks were used in an experiment to study the effects of different dietary levels of garlic and copper on the performance, carcass characteristics and serum and tissue cholesterol levels of broiler chicks. The experimental period was comprised between the first 21 days of age of the birds. A completely randomized design was used in a factorial 3 × 3 with the following levels: garlic (0, 1.5, and 3.0%) and copper (0, 125, and 250 mg/kg of […]
