Supplementation of sucupira oil in broiler diets

ABSTRACT The objective of the present study was to ascertain the effect of sucupira oil in diets of broilers on gut development, dry matter and nitrogen metabolizability and broilers performance. A total of 350 one-d-old, male, Cobb500® broiler were allotted in seven treatments with five replicates, totaling 35 experimental units with 10 birds each. The dietary treatments consisted of a negative control diet, four diets with different levels of sucupira oil (100; 500; 900 and 1,300 mg/kg), diet with mannanoligosaccharide and control diet with antibiotic. The inclusion of 900 and 1,300 mg of sucupira oil impaired gut development and metabolizability of nutrients (P<0.05). The inclusion of 100 or 500 mg of sucupira oil in broiler feed was similar to negative control, MOS and antibiotic treatments for performance variables (all phases studied) and also for nutrient metabolizability (P<0.05). It can be concluded that high levels of sucupira oil is not recommended in broilers diet.
