Desempenho produtivo e qualidade da carne de frangos alimentados com ração contendo óleo de linhaça

Abstract

The objective of this work was to assess the effect of linseed oil as a substitute to soybean oil on yield performance and meat traits of broilers of both sexes. Three hundred and twenty birds were raised in a 4x2 factorial arrangement, consisting of four receiving periods combinations of soybean oil and linseed oil and two sexes, with four replications. Yield performance was evaluated by weighting feed and broilers aging 1, 21, 42 and 49 days, when they were slaughtered. After slaughtering, carcass yield and composition in main cuts, viscera and abdominal fat were quantified. Total lipids, moisture and cholesterol contents in meat were determined. Linseed diets improved the nutritional quality of the lipid fraction of broilers meat but were harmful to broilers performance.
