Histoarchitectonics of Retina of Chicken Embryos in Ontogenesis

Abstract

Development of industrial poultry farming allows obtaining a large number of quality products with effective payback period of feed in a short time. The growth in the poultry production has become significant and sustainable primarily due to an increase in grain production, as well as the creation of a solid forage base, which is used in poultry feeding. The main food poultry products are eggs and meat, and their production largely depends on genetically determined productivity. Fertility and viability of birds depends on changes that occur under the influence of environmental conditions. The article presents data on the histoarchitectonics of retina in chicken embryos studied on the 7 th , 10 th , 13 th , 15 th , 17 th and 20 th days of incubation of antenatal ontogenesis and 40 th day of postnatal ontogenesis. It was established that the effect of riboflavin on the retina in the eye contributes to an increase in the number of cells per unit area, which leads to an increase in the thickness of its layers. Keywords—chicken embryo, retina, riboflavin, antenatal ontogenesis.
