Abstract
The experiment was carried out using 300 unsexed chicks of a commercial broiler breed available in Syria, breeding started in 1/9/2018. The chicks were distributed into five groups, each consisting of 60 chicks. The chicks of the five groups were subjected to specific methods during the first 24 hours of age as follows: First group chicks which fasting for the first 24 hours and the second group chicks (traditional diet) feeding using technically modified diet (5% gel materials, 50% water and 45% basal diet without adding any food products studied), the third group (glycerin 5%) feeding using technically modified diet with the same composition of the diet in the second group with 5% glycerin, the fourth group (egg powder 5%) feeding using technically modified diet with the same composition of the diet in the second group with 5% egg powder, and the fifth group (glycerin 5% and egg powder 5%) feeding using technically modified diet with the same composition of the diet in the second group with 5% glycerin and 5% egg powder. for 24 h after hatching. After that, all chicks of the five groups were provided with a broiler diet for each age stage until the experiment was completed at the age of 42 days. Results showed a positive significant (P≤0.01) in the live body weight of the chicks of the groups fed technically modified diets at the end of the first week compared with the group chicks that had fasting the first 24 hours of age, while only live body weight in the birds of the second group (control technically modified diet) significantly (p≤0.01) compared to the first group which fasting first 24 hours at the end of the sixth week. The immunological results indicated a significant effect (P≤0.01) in the immunosuppressive antibodies of Newcastle disease in all groups that gave them technically modified diets compared to the first group which fasting first 24 hours of life. In addition, early feeding by using technically modified diets contributed to speed up the immune response of the Newcastle vaccine in chicks compared with chicks that fasting in first 24 hours and thus contribute to the evolution of the immune system in birds.
