Composition of fatty acids in tissues of broilers fed by-products of passion fruit

The fatty acids composition of broiler tissue was evaluated using two hundred male Cobb chicks. They were raised from 22 days of age with experimental diets based on corn and soybean meal supplemented with 4 or 8% of passion fruit peel and 4 or 8% of passion fruit seed. A completely randomized experimental design was used with a 2 x 2 factorial arrangement with an additional treatment (Control, 0% of passion fruit byproducts), with four replications and ten birds per experimental unit. A orthogonal contrast with two levels of supplementation and two types of byproducts., The birds were slaughtered at 42 days of age for fatty acids composition analyses. The use of passion fruit seed reduced the content of palmitic C16:0, estearic C18:0 and docosahexaenoic acid C22:6 in the breast. In the leg, passion fruit byproducts increased the content of linoleic C18:2, linolenic C18:3 and palmitic acid C16:0 and reduced the content of estearic acid C18:0.
