EFFECT OF ADDINING VITAMINS E AND SC TO BROILER RATION CONTAINED HIGH LEVEL OF TALLOW IN CARCASS TRAITS

Abstract

This study was conducted in poultry–Field which related to Animal production department – college of agriculture and forestry –University of Mosul. From a period From 5 November 2022 to 17 December 2022 for (42) days . The aim of the study the addition of fat to the feeding mixtures was identified the effect of adding Tallow as a source of energy instead of grains with addition of vitamin C or E or their combination to the ration on Carcass traits. Two hundred forty Ross (308) one day old unsexed chickens used in this study. Birds distributed to five treatments (Four replicate of each twelve birds in each replicate). Reared in semi- opened house and the treatments were as follows: T1 (control) without addition, T2: Addition 6% of Tallow to ration, T3: Addition 6% of Tallow to ration and 250 mg Vitamin E / kg feed, T4: Addition 6% of Tallow to ration and 250 mg Vitamin C / kg feed, T5: Addition 6% of Tallow to ration and 250 mg Vitamin E / kg feed and 250 mg Vitamin C / kg feed. Statistical analysis of data showed: Significant increase (P < 0.05) in Live body weight in treatments of Tallow and Vitamins as compared with control, also the adding of Tallow and Vitamins caused highest dressing percentage, High percentage of drip loss by cooling in treatments of adding tallow and adding Tallow and Vitamin C. No significant differences between treatments in the relative weight of the chest, thighs, back, two wings and neck. And reduce the speed of passing feed in digestive track for treatments of adding Tallow and Vitamins as compared with control. We can conclude the adding tallow as a source of energy instead of grains with addition of vitamin C or E or their combination to the diet significantly improved the broiler Carcass traits
