EFFECT OF SPRAY THE FERTILIZED HATCHING EGGS WITH VITAMIN C AND AIBUMIN, DEXTRIN INJECTION ON THE HATCHED TRAITS AND POST HATCHED CHICKS OF BROILER ROSS 308

Abstract

This study has aimed to improve characteristics of hatching and quality of hatched broiler chicks by spraying fertilized hatching eggs with vitamin C or/and injection with Albumin and Dextrin on. One hundred sixty-two fertilized eggs were randomly assigned to 9 treatments with 3 replications, each with 6 eggs. The eggs were subjected to the treatments as follows: T1 control group, without spray or injection, T2 injected with 0.5 mL of distilled water, T3 injected with 0.5 ml 12% Albumin egg, T4 injected with 0.5 mL of 20% Dextrin, T5 injected with 0.5 ml mixture of 12% Albumin egg + 20% Dextrin, T6 spraying of vit C only, T7 injected with 0.5 ml of 12% Albumin egg + spray with vit C, T8 injected with 0.5 ml of 20% Dextrin + Taurine Ascorbic acid powder, T9 injected with 0.5 ml mixture of 12% Albumin egg + 20% Dextrin + Spray vit C. the results showed there were no significant differences on hatching rate of fertile eggs, late embryonic mortality, alive pipped, dead pipped, length of the chick, Tuna traits and percentage weight of liver. The body weight of chicks increased significantly in T9 compared to T3 and T4, without any differences among other treatments. However, the percentage of remains yolk was decreased in T4 as the lowest of percentage weight of remains yolk among treatments. The percentage weight of heart was significantly increased in T5 among other treatments. The T4 was higher than T1, T3 and T7 in term of gizzard percentage weight, T8 was superior in percentage weight of glandular stomach among all treatments. Significant difference was observed in percentage weight of fabricia gland and intestine for T5 compared to others. High significant differs in length of villa for intestinal tissue in T8 and T9 compared with other treatments. We conclude from this study that injection Dextrin + spraying with vitamin C has significantly improved the rate some relative weights of internal organs, the most important of which is the relative weight of bursa.
