INFLUENCE OF SUPPLEMENTING DIFFERENT LEVELS OF VITAMIN E IN THE RATION ON SOME PRODUCTIVE AND PHYSIOLOGICAL CHARACTERISTICS IN BROILER CHICKENS

Abstract

This experiment was carried out in the . Animal Production Department – Technical Institutel AL- Musaib . to investigate the effect of supplemeting four levels of vitamin E 0 , 100 , 200 , and 300 mg kg which represent four treatments is 1st , 2nd , 3rd and 4th respectively on some productive and physiological trats of broiler chickens strain Arbor – Acres at age 3 and 6 weeks. The results refered to dominance the treatment 4th upon treatment 1st in body weight , while there is no recorded significant different among treatments 1st , 2nd and 3rd . Feed consumption we notice a significantly dominant of treatment 3rd and 4th upon 1st and 2nd also no signifieant difference in feed conversion ratio at 7 week age among all treatment in this study concerning plasma glucose concentration we notic asignificant dominant of treatment 4th upon treatment 1st also treatments which contain vit . E (2nd , 3rd and 4th ) recorded asignificanty dominant upon the treatment 1st in plasma cholesterol There is no significan differences among all treatments in plasma total protein concentration .
