[The growth of abdominal adipose tissue in various production-type of domestic fowl].
At hatching, the abdominal fatty tissue is less developed than the subcutaneous fatty tissue. However, it grows more intensively during the post-incubation period through both the hyperplasia and hypertrophy of the fat cells. In the cocks, hyperplasia reaches its peak at the age of 9 weeks, followed by a decrease; then hyperplasia continues until the age of 25 weeks. In the hens the peak of hyperplasia comes later, at the age of 14 weeks; then it decreases until the age of 25 weeks is reached. Hyperplasia and hypertrophy are more pronounced in the early period and are somewhat higher in the cocks. During the period of sexual maturation both processes are more intensive in the hens; owing to them, the total weight of the abdominal fatty tissue of hens increases both absolutely and relatively in comparison with the cocks. The cellularity of the first population of adipocytes is assumed to culminate at the age of three to five weeks. Then follows the cellularity of the second population which persists throughout sexual maturation. The pictures of hyperplasia and hypertrophy are qualitatively the same in different production types of fowl, but the size is twice as large in the broiler type than in the laying type of fowl.
