Morphological changes of eye lens in chicken embryos on day 5, 7 and 10 of incubation

Abstract

Today, poultry farming is the most dynamic sector of the entire agro-industrial complex. The increase in agricultural production is one of the most important national economic tasks. In order to successfully accomplish this task, it is necessary to improve the organization of cultivation, to develop on-farm and inter-farm specialization, to introduce intensive production methods. Vision is an important physiological process by which birds get an idea of the size, shape and color of objects, their relative position and distance and, thus, acquire the ability to move in the surrounding space. The simplest form of developing a visual analyzer is the start of a reaction to light. The anatomical features of the bird's visual analyzer indicate that vision plays an important role in their life. Using the organ of vision, birds receive up to 80% of information from the outside world. The effect of a solution of vitamin B2 (riboflavin) with a concentration of 0.002% was studied. The aim of our study was to study the use of vitamin B2 (riboflavin) morphological, morphometric and histological methods for the development of the lens in embryos at 5.7 and 10 days of incubation. For laboratory studies, these methods were used: morphometric, histological, anatomical, and variation-statistical. 600 hatching eggs were divided into experimental and control groups. In the experimental group, eggs were lowered into a solution of riboflavin with a concentration of 0.002%, and in the control group of the egg, preincubation treatment was not carried out.Keywords: Chicken embryo, visual analyzer, lens, riboflavin, antenatal ontogenesis.
