Effect of Dietary Xylanase enzyme Supplementation on the Performance of Growing Crossbred Pigs

AbstractA study examined whether xylanase enzyme supplementation could improve performance in growing crossbred pigs fed diets with lower energy content. The experiment used eighteen crossbred pigs (Large White Yorkshire × local pig crosses), 4 months old, divided into three equal groups of six animals each based on average body weight. The pigs were fed according to BIS (2023) standards (18% crude protein, 3170 kcal ME/kg), with the following treatment groups: T0: Standard pig grower diet (Control), T1: Control diet with energy reduced by 100 kcal ME/kg (Negative control) and T2: Negative control diet supplemented with xylanase (100 g/t). The feeding trial was conducted for 60 days during which daily dry matter intake, weekly body weight changes and body weight gain were recorded. The results indicated no significant differences in body weight, body weight gain, feed conversion ratio, or dry matter intake among the groups. The initial and final body weights were similar across all groups and the body weight gain remained consistent. Hence, the supplementation of xylanase did not significantly improve the growth performance in growing crossbred pigs.
