Vitamin E (Vit E) is included at high doses in commercial broiler feeds to boost performance because of its antioxidant function. Phytogenic feed additives with antioxidant properties might be used to spare or replace Vit E as antioxidant and reduce costs. Previous studies with an encapsulated product based on spices…

Essential oils are often used to improve palatability of swine feed. As a natural product, their composition varies, leading to inconsistent results under experimental conditions. Reconstituted versions that mimic the properties and allow standardized blends could clearly demonstrate their effects.

This study aimed to investigate the effects of supplementing broiler chicken diets with an encapsulated product based on capsicum and other spice (black pepper and ginger) extracts on growth performance, nutrient digestibility, digestive enzyme activity and antioxidant response. To this end, 480 1-day-old male chicks were randomly assigned to two…
