Effect of linseed and rapeseed or linseed and rapeseed oil on performance, slaughter yield and fatty acid deposition in edible parts of the carcass in broiler chickens

The objective of the study was to investigate the effect of linseed and rapeseed or respective oils on performance indices, nutrient digestibility, metabolizable energy of diets, digesta viscosity, and yield and chemical composition of edible and non-edible parts of the carcass of broiler chickens,...

Description
Summary:The objective of the study was to investigate the effect of linseed and rapeseed or respective oils on performance indices, nutrient digestibility, metabolizable energy of diets, digesta viscosity, and yield and chemical composition of edible and non-edible parts of the carcass of broiler chickens, with particular attention to n-3 PUFA. Two experiments were performed on 134 female broiler chickens, randomly allocated to 3 groups of 22 birds (Experiment 1) or 2 groups of 24 birds (Experiment 2) and 10 birds to a zero group. The chickens were kept in individual cages. Five wheat-based and xylanase-supplemented diets containing about 80 g crude fat per kg were prepared. The source of added fat was in control diet lard (61 g/kg) in experimental diets half of the lard was substituted by: linseed oil (LO) or full-fat lin-seed (L), rapeseed oil (RO) or full-fat rapeseed (R). Chickens were given the control or experimental diets from days 8 to 42 of life, then they were slaughtered, the carcasses were divided into edible and non-edible parts, and their chemical composition determined
