This study aimed to evaluate the effect of four combinations of dietary linseed oil and
lysine mixtures on performance, fatty and amino acid profiles, oxidative stress biomarkers, cell
energy and meat quality parameters of broiler chickens. One hundred and sixty broiler chicks were
allocated into four groups. Birds of groups 1–4 were fed diets containing optimum lysine and 2%
of linseed oil, optimum lysine and 4% of linseed oil, high lysine and 2% of linseed oil, and high
lysine and 4% of linseed oil, respectively, for a period of 35 days. High linseed oil or lysine levels did
not affect the performance of the tested birds, but the high level of dietary linseed oil decreased the
concentrations of muscles’ saturated fatty acids (SFA). The highest values of !-3 polyunsaturated
fatty (!-3 PUFA) and arachidonic acids with lowest levels of monounsaturated fatty (MUFA) were
detected in the muscles of birds fed diets containing high linseed oils and/or lysine levels. High
linseed oil or lysine levels provided the best essential amino acid profile and improved antioxidant
components as well as cell energy, and tenderness and redness of the meat. Conclusively, high dietary
lysine and linseed oil combinations improved the nutritional value, antioxidant status and cell energy
of broiler chickens’ meat |
