[The development and growth of subcutaneous adipose tissue in various production types of domestic fowl].
Hyperplasia and hypertrophy of fat cells of the subcutaneous adipose tissue were studied in different production types of fowl in the post-incubation period. The cocks and hens of laying type were found to have fewer and smaller fat cells than the birds of broiler type. The highest hyperplasia was recorded in the first nine weeks of age, then followed a decrease, lasting until the 25th week. Hypertrophy continued step by step throughout the period of study and increased when hyperplasia decreased. The differences between sexes increase during sexual maturation: in the hens the hypertrophy of cells increases and hyperplasia does not decrease so quickly as in the cocks. Before sexual maturity, hypertrophy as well as hyperplasia are somewhat higher in the cocks.
