Abstract
This study was conducted to find out the health status of the internal organs of birds and some characteristics of the carcass using the system of gradual increase in the intensity of illumination in the chicks of the broiler. 224 Ross 308 chicks were used in this study at the age of one day. The chicks were randomly distributed to 4 treatments with 4 replications for each treatment (14 chicks/duplicate). The transactions included the following: T1 lighting program according to the guide for 308 ROSS company (control treatment). T2 Lighting program according to the guide and a gradual increase in the intensity of lighting and a gradual reality of light every 20 minutes. T3 Lighting program according to the guide and a gradual increase in the intensity of lighting and a gradual reality of light every 40 minutes. T4 Lighting program according to the guide and a gradual increase in the intensity of the lighting and a gradual reality of the light every 60 minutes. Both the characteristics of the carcass and the internal organs of the experimental birds were studied, and the results showed a significant increase in the grooming ratio of all experimental treatment birds compared with the control treatment, and a significant increase in the relative weight of the duodenum for the fourth treatment compared with the third and second treatment without a significant difference with the control treatment The relative weight of the spleen was significantly superior to the fourth and second treatment compared to the treatment. The rest of the traits did not show any significant differences, the different parameters, the back, the thigh, the drum stick, Abdominal, wings, legs, heart, liver, stomach, glandular, pancreas, pod of Fabricia, bile, jejunum, ileum, cecum is full, cecum is empty. Thus, we conclude that the intensity of lighting has a positive effect in raising the percentage of netting in the carcass of birds exposed to the gradual intensity of lighting.
