Effect of inorganic chelate of zinc and restaurant residual oil added to feed mixture on the biochemical traits of thigh muscles in male broilers

An experiment was planned to study the influence of restaurant residual oil (RRO) and inorganic chelate of Zn (ZnO) on triglyceride (TRG), cholesterol (CHOL) and malondialdehyde (MDA) concentrations of thigh muscles in male broiler chickens. In the present research, three hundred and twenty four 10-day-old male broiler chicks (Ross 308 strain) in nine treatments including three levels of experimental oil (0, 2.5 and 5%) and three levels of ZnO (0, 50 and 100 mg/kg of feed) were fed until 42 days. The results showed that using RRO, total biochemical traits (TRG, CHOL and MDA) of muscles increased, MDA (p < 0.01), CHOL (p
