Abstract:
This study was conducted at poultry farm, Animal Resources Department, College of Agriculture University of Basrah from 4/4/2010 to 15/5/2010 for the first experiment and from 8/112010 to 19/12/2010 for the second experiment. The aim of this study was to investigate the effect of early (8 - 21) and late (21 - 34) day of feed restriction by partial 20% with adding IRAQI probiotic at level 0.3% for (first experiment) and propionic acid at level 0.3% for the (second experiment) in productive performance and some physiological of blood and small intestine. One day of 270 unsexed chicks of Ross 308 strain were used in the study. The chicks were randomly distributed into 6 treatments with three replicates. Each replicate contain 15 chicks. Results of first experiment indicated that : 1 - There was a significant (p<0.05) increase in control treatment with IRAQI probiotic on live body weight and body weight gain. While, there was a significant (p<0.05) decrease in the late feed restriction treatment with, or not adding probiotic.2 - There was a significant (p<0.05) increase for the control treatment with, or not adding probiotic in feed consumption.3 - There was a significant (p<0.05) improvement in feed conversion ratio of early and late feed restriction with, or not adding probiotic.4 - Late feed restriction and early feed restriction with probiotic cause significant (p<0.05) decrease in mortality comparing with control treatment.]b[5 - There was a significant (p<0.05) decrease in abdominal fat for the treatments early and late feed restriction with, or not addition probiotic as compared with the control treatment.6 - There was significant (p<0.05) reduction in Intestine PH for the treatment adding probiotic, but there was no differences between the treatments in Ceca PH.7 - There was a significant (p<0.05) decrease in total protein, albumin, cholesterol and glucose in blood serum for the chicken with early feed restriction (not adding probiotic), and there was significant (p<0.05) increase GOT and GPT levels in the same treatment at the age of 21 days, Addition of IRAQI prpbiotic showed a significant (p<0.05) reduction of serum cholesterol, GOT and GPT as compared with control treatment.8 - There was a significant (p<0.05) decrease in cholesterol, GOT and GPT by the addition IRAQI probiotic compared with control treatment at 42 days.Results of second experiment indicated that : 1 - There was a significant (p<0.05) decrease in the treatments (late feed restriction, early and late feed restriction with, or not adding propionic acid) on live body weight and body weight gain.2 - There was significant (p<0.05) decrease in feed consumption for the treatment early and late feed restriction with, or not addition propionic acid. 3 - There was significant (p<0.05) decrease in feed conversion for the treatment early and late feed restriction with addition propionic acid compared with the other treatments.4 - Late, early feed restriction with or not addition propionic acid cause significant (p<0.05) decrease in mortality compared with control treatment, and there was significant (p<0.05) reduction in production index for the treatment early and late feed restriction with addition propionic acid as compared with the other treatments.5 - There was a significant (p<0.05) decrease in abdominal fat for the treatments early and late feed restriction with, or not addition propionic acid compared with the control treatments.6 - There was a significant (p<0.05) decrease in total protein, globulin, cholesterol and glucose in blood serum for early feed restriction with, or not adding propionic acid, but there was significant (p<0.05) increase at the level of GOT and GPT in the same treatment compared with the other treatments at the age of 21 days.7 - Serum cholesterol showed significant (p<0.05) reduction in the late feed restriction with, or not adding propionic acid compared with the other treatments at the age of 42 days.
