| Abstract | ||
| The present study was carried out to investigate the effect of using 10 % and 20 % corn distiller's dried grains with solubles (CDDGS) as partial replacement for yellow corn and soybean meal with or without adding 0.05 % Galzym powder on productive performance, some blood plasma parameters and the immune response of broiler chicks. A total number of 240 day-old, unsexed broiler chicks were randomly assigned to six treatments 40 chicks each. The first group was fed basal (starter and grower-finisher) diets without supplements and considered as control (T1) group, the second group was fed as T1 plus 0.05 % Galzym (T2), the third group was fed 10 % CDDGS (T3), the 4th group was fed as T3 plus Galzym addition, the 5th group was fed 20 % CDDGS (T5), the 6th group was fed as T5 plus Galzym (T6). The obtained results showed that final live body weight values increased by CDDGS replacement. The highest final live body weight, total feed intake and total body weight gain values were recorded by the birds fed 20 % CDDGS level with Galzym as compared to other experimental treatments. Also, the lowest total feed conversion values were recorded for the birds fed 20% CDDGS plus Galzym as compared to other experimental birds. The results showed that there were significant increase in the experimental treatments in plasma total protein and total triglycerides values compared with the control treatment. Moreover, there were insignificant increases in total cholesterol values compared with the control group. Also, there were significant decreases in plasma inorganic phosphorus values as compared to the control treatment. The specific immunity against avian influenza disease virus (AIDV) titer was significantly increased when using 10 % CDDGS with Galzym supplementation in the diets after vaccination as compared to other experimental samples. Also, there were insignificant differences in the Newcastle disease virus (NDV) titer after vaccination among all the experimental treatments. It is concluded that using CDDGS up to 20% in broiler diets as partial replacement for yellow corn and soybean meal with or without Galzym supplementation improved growth performance of broiler chicks and enhanced the specific immunity against avian influenza disease virus titer, with no adverse effects on their physiological blood parameters. | ||
