An experiment was conducted using Bovans White layers to investigate the effects of 30% whole-wheat inclusion in a standard layer diet supplemented with xylanase, on laying performance, digestive organs and ileal mucosa development. Three dietary treatments were used: 1) control diet (30% ground wheat); 2) 30% whole wheat; 3) whole wheat+wheat xylanase. Xylanase was added to whole wheat at 150g/ton. Including the pre-experimental period the trial lasted for 13 weeks. Xylanase supplementation to whole wheat significantly (P

The experiment was conducted to evaluate the effects of organic acid mixture and/or mannanoligosaccharides (MOS) on growth performance, blood parameters and intestinal microbiota in 120 Ross 308 male broiler chicks, over a period of 21 days. Birds were maintained in battery brooders confined in an environmentally controlled experimental room. There were 4 dietary treatments, each consisting of 6 replicates. Dietary treatments were: (i) basal diet (as a control), (ii) basal diet + MOS 2 kg/ton feed, (iii) basal diet + organic acid mixture 3 kg/ton feed and (iv) basal diet + MOS 2 kg/ton feed + organic acid mixture 3 kg/ton feed. Weight gain of the broilers in this study was significantly influenced by the addition of organic acid mixture (P
