Effect of dietary supplementation of linseed (Linum usitatissimum) on the growth performance and lipid profile of broiler chickens

Abstract

Broiler diets frequently include fats and oils to improve energy density, feed palatability, and functionality associated with Ω-3 PUFA. The purpose of this research was to examine how dietary supplementation of linseed affects growth performance and lipid profile of broiler chickens. The study was carried out at the poultry farm of the Banaras Hindu University, Varanasi. The experiment is approved by the Central Animal Ethics Committee of the University (IAEC/3036). Total 200 male Cobb-400, 7-day-old broiler chicks were randomly distributed into 5 treatment groups and fed with different levels of LS (0, 2.5, 5, 7.5, and 10%), respectively. The chickens fed rations supplemented with different levels of LS resulted in significantly decreased body weight and significantly increased feed conversion ratio. In blood lipid profile, CHO, TRI, LDL-C, and VLD-C concentrate levels decreased when fed with different level of LS, while HDL-C increased significantly.
