Chicken Skin of the Dominant CZ Cross System

Abstract

Sustainable development of agricultural systems and livestock sectors includes the raising of productive poultry, including chickens, as an important aspect. To increase the efficiency of egg and meat poultry farming, the genetically determined viability and productivity of chickens should be ensured with optimal feeding and maintenance programs. The skin of the epidermis, dermis and subcutaneous layer protects the body of chickens from external damage, exposure to extreme temperatures, and the penetration of pathogenic microorganisms. Knowledge of the skin condition as a system of tissues and plumage, depending on the species, age, breed, cross and housing conditions of the bird, allows you to optimize the production of high-quality eggs and meat. Histology makes it possible to reveal the principles of the structural organization and development of tissues and their systems in order to control the life processes of the bird’s body: metabolism, development, growth, heredity, reproduction, productivity. In this regard, the purpose of the study was a histomorphological assessment of the features of the chicken skin structure of the Dominant CZ cross system when reared on the floor. We used skin samples from the back of chickens “Sussex D-104” (“D-104”), “Blue D-107” (“D-107”), “Black D-849” (“D-849”). In a special laboratory, generally accepted pathomorphological and histological techniques were used. We found that significant differences in the skin structures of chickens were only at 28 days of age.
