Effect of Feed Restriction period and Vit. C. Addition on Some Physiological Blood Traits of Broiler

Abstract

This experiment was conducted at poultry farm, Animal Resources Department, College of Agriculture University of Basrah, within period from 20/11/2007 to 8/1/2008. The aim was to investigate the effect of early (10-42) and late (25-42) day by partial 80% of ad-libtum feeding feed restriction with different level Vitamin C (0, 100 and 200)mg/L of water on, some blood physiological . A total of 324 unsexed chicks of Ross strain aged one day, were used in the study. The chicks were randomly distributed into 9 treatments with three replicates. Each replicate contain twelve chicks. Each chick was given Vitamin C at the day 8 of age till 42 day of age. Results indicated that there were no significant effect of vitamin C and feed restriction on RBC , WBC, Hb and PCV% at the age of (28) day. However, there were no significant effect of Vitamin C on number of RBC, WBC, PCV, Hb, H/L, cholesterol, glucose at the age of 49 day. while there was no influence of feed restriction on WBC and Hb at the age of 49 day. There were significant effect of vitamin C and feed restriction on cholesterol and glucose concentrate at the age of (28) day. There was significant(p<0.05) reduction due to feed restriction in RBC and PCV% at the age of 49 days. There were a significant effect due to the interaction of feed restriction and Vitamin C on all studied characters at the age of 49 days.
