Factors Affectıng Abdomınal Fat in Chıckens

In broiler chickens, 15-20% of the total body weight consists of fat. The most variable carcass component in broilers is fat. Abdominal fat accounts for approximately 2-3% of live weight. In broiler chickens, age and gender have a significant effect on fat deposition. there is a correlation between body weight and the level of fat deposition. The differences in abdominal and carcass fat content between genotypes indicate the importance of genetic effects on fat storage. Nutrition factors have a significant impact on the carcass composition of broiler chickens. Generally, high-energy diets provide advantages for live weight gain and feed efficiency, but can lead to excessive fat deposition. Environmental factors such as ambient temperature, housing systems, lighting programs, and physical activities are directly related to the life span and physical activities of poultry and affect fat storage. The caliper tool was first developed to estimate abdominal fat thickness in live broiler chickens, and significant phenotypic correlations were found between with this technique and abdominal fat weight.
