Abstract

In this study, the effect of different levels of fat with antibiotics and probiotics on blood biochemical traits and performance of broiler chicks was investigated. In a factorial experiment, 288 Day-old Ross broiler chicks treated with two level of fat (3 and 6 percent) and three additives (Flavomycin, Protexin and none-additive). The birds were allocated randomly in six treatments with four replicates and 12 birds per replicat. Results showed that the chicks fed on diets containing 3 percent of fat + Flavomycin had higher feed intake and body weight gain compared to birds fed with fat + Protexin (P< 0.05). The concentration of cholesterol, HDL and LDL in serum of birds of 6% fat was more than of those fed diets with 3% fat. Birds fed diets containing protexin had lowest cholesterol, HDL and LDL (P< 0.05). It was concluded that supplementing the rations containing fat with probiotics decrease feed intake and body weight gain in broilers chicks and their performance decrease by increasing fat in diets.
