Popis: This study was conducted to determine relative bioavailability (RBV) of basic zinc chloride (BZC) compared to zinc sulfate monohydrate (ZSM) for broilers. A randomized design involving a 2 × 3 factorial arrangement of the different treatment regimens plus one negative control was set up for this study. A total of 630 newly hatched male AA broiler chicks were randomly allocated to 42 different pens (15 chickens/pen) and assigned to 7 dietary treatments in a completely randomized design. The diet was supplemented with 0, 20, 40, or 80 mg of Zn mg/kg of feed in the form of ZSM or BZC. The results showed that zinc supplementation altered average daily gain (ADG) and feed conversion ratio (FCR) (P
