Abstract

This experiment was conducted in order to evaluate effects of dietary PROTEIN level and BETAINE supplementation on performance and some blood parameters in BROILER chickens subjected to HEAT STRESS. For this purpose, two basal diets were formulated according to NRC (1994) recommendation (19.4 % CP) and 0.85% of NRC (16.63 % CP) for PROTEIN. Each of the two basal diets was also supplemented with beanie at 1.5 gr/kg of diet, resulting to 4 dietary treatments. The diets were fed ad- Libitum to six replicate groups of 18 mixed sex BROILER chicks of Ross strain from 21 to 49 days of age. The birds were exposed daily to HEAT STRESS for 8 hours (10:00 to 16:00h). Six birds in each replicate (3 birds from each sex) were wing banded in order to measure body temperature and blood parameters before and after HEAT STRESS. The results of experiment indicated that BROILERs were fed NRC PROTEIN diet with supplementation of betain had significantly higher weight gain (P<0.05) than those were fed low PROTEIN diets. Reducing dietary PROTEIN level resulted to decrease feed intake (P<0.05).Supplementing of BETAINE and dietary PROTEIN level had no significant effect on feed conversion ratio (P<0.05). BROILERs were fed NRC PROTEIN diet had higher tight weight and lower abdominal fat than those were fed 0.85% NRC PROTEIN diet. Dietary PROTEIN level had no significant effect on blood glucose and urea before and after HEAT STRESS challenge (P>0.05), but had significant effecting blood uric acid concentration before heating time (P<0.05). Supplementing betain have not any significant effect on blood glucose, urea and uric acid (P>0.05). Blood uric acid concentration was higher in female than male before heating time (P<0.05). HEAT STRESS challenge resulted to significantly increase of blood glucose, urea and uric acid concentrations (P<0.05).
