从选定的基因系的肉鸡饲喂高能量谷物饮食，以实现更大的货币回报。来自Tegel TM 70白色肉鸡的腹部脂肪垫的细胞生长的特征在于脂肪细胞的增生和肥大，直到鸡成年。14周龄，在此之后，现有的脂肪细胞肥大是唯一负责这些脂肪沉积物的质量增加。体脂百分比与腹脂重呈线性正相关。在身体脂肪百分比不变的情况下，雄鸟腹部的脂肪存款比雌鸟多。对于每种性别，预测身体脂肪的关系都不同。在成熟鸟类中，脂肪组织存款的质量通常反映在脂肪细胞的大小而不是脂肪器官中细胞的数量。
Broiler chickens from selected genetic lines are fed high energy grain diets to achieve a greater monetary return. Cellular growth of the abdominal fat pads from Tegel TM70 white broiler chickens was characterized by both hyperplasia and hypertrophy of adipose cells until the chickens were .apprx. 14 wk old, after which hypertrophy of existing adipose cells was solely responsible for increases in the mass of these fat deposits. The percent body fat was linearly and positively correlated with the weight of abdominal fat. At a constant percent body fat, male birds had a larger deposit of fat in the abdominal region than did females. A different relationship to predict body fat would be required for each sex. In mature birds, the mass of an adipose tissue deposit is generally reflected in the size of adipose cells rather than the number of cells in an adipose organ.
