STUDYING MEAT QUALITY TRAITS BYUSING REGULATORY FACTOR GENES EXPRESSION IN BROILER STRAINS

Abstract

This testing be carried in next to Poultry farm, poultry creation sector, Faculty of cultivation, Ain Shams University. The most important geals of the near study on the genetic studies for determining genes Poultry strains responsible for the quality of the meat. In general, studies trait of Ross and Indian River will be discussed later in details. The main results obtained could be summarized as follows. 1.Heat measurements 1.1. Respiratory rate The showed results that Indian River strain was high significant in this the age compared to Ross strain. Also, found that treatment was high significant in this the age compared to control group. 1.2. Rectal temperature Rectal temperature of Ross and Indian River strains was not a significant effect of strains. But, and treatment was high significant in this the age compared to control group. 2. Body weight It could observe that no effect significant between strains (Ross and Indian River) at 1,2and3 week of become old. But, found consequence to a great size heavier boring deceased substance at 4 also 5 weeks of older for Indian River weigh against to Ross strain. However, the heat treatment was a significant decrease body weight at different age from these studies. 3. body weight gain showed that body weight gain and of Indian river and Ross broiler chicks. The results revealed that the body weight gain at 14-28 day of age of Indian river broiler chicks was significantly heavier than that for Ross ones. However, at 28-42 day of age, the Ross broiler chicks were
