Effect of inclusion of lysolecithin or multi-enzyme in low energy diet of broiler chickens

A total of 672 one-d-old Ross 308 (mixed gender) broiler chicks with an average initial body weight of 34.1 ± 0.2 g were used in a 28-d feeding trial to investigate the effect of supplementing low energy diets with an emulsifier or multi-enzyme complex on broiler. Chickens were allocated to one of six treatments with seven pens/treatment and 16 birds/pen. Treatments were (1) PC (basal diet), (2) NC (PC-100 kcal ME/kg), (3) L05 (NC + 0.05% emulsifier), (4) L10 (NC + 0.10% emulsifier), (5) E05 (NC + 0.05% multi-enzyme), and (6) E10 (NC + 0.10% multi-enzyme). Results showed that supplementing low energy diet with 0.10% multi-enzyme or 0.10% emulsifier improved (P
