EFFECT OF ADDINING VITAMINS E AND C TO BROILERS RATION CONTAINED HIGH LEVEL OF TALLOW IN PRODUCTIVE PERFORMANCE

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 of 5 November 2022 t0 17 December 2022 for (42) days. The aim of the study 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 ratio. two hundred forty Ross 308 one day old unsexed Broiler chicks used in this study.

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 Weight gain in the treatments of adding Tallow and Vitamins as compared with control , also the adding of Tallow and Vitamins caused  highest dressing percentage. Significant improvement in feed conversion ratio for treatments adding Tallow and Vitamins as compared with control. No significant differences between treatments in in feed consumption and relative weight of heart and liver. Significant decrease relative weight of gizzard in digestive track for treatments of adding Tallow and Vitamins as compared with control
