EFFECTS OF DIETARY L-CARNITINE TO DIETS WITH DIFFERENT FAT SOURCES ON PRODUCTIVE PERFORMANCE OF BROILER

Abstract

Abstract The study was conducted to investigate the effect of adding two levels of Carnitine (L-Carnitine) to diets differs with fat sources (vegetable or animal) on productive performance of broilers. A total of 288 broiler chickens (Ross308) were used in the study, randomly distributed to eight treatments with three replicates per treatment (12 chicks/replicate). The experimental treatments were involved T1: diet with sunflower oil (free of carnitine), T2: diet with animal fat (free of carnitine), T3: dietincluded sunflower oil with 100 mg carnitine/kg feed, T4: diet included sunflower oil with 300 mg carnitine/kg feed, T5: diet included animal fat with 100 mg carnitine/kg feed, T6: dietincluded animal fat with 300 mg carnitine/kg feed, T7: diet included a mixture of animal fat and sunflower oil with 100mg carnitine/kg feed, T8: diet included a mixture of animal fat and sunflower oil with 300mg carnitine/kg feed. The obtained results showed that there were no significant differences were detected between different treatments in productive performance traits at the age of 42 days, which included live body weight, body weight gain, feed consumption and feed conversion ratio.
