Optical effect of the red spectrum on the linear parameters of turkey embryos during incubation

Abstract

The relevance of the topic is determined by the growing scientific interest in the role of photobiological regulation of the processes of embryonic development of poultry. The red spectrum of visible light is able to influence the linear parameters of poultry embryos, the rate of organ formation and metabolism. Optimization of environmental factors, in particular lighting conditions, is becoming an important area of scientific research aimed at increasing the yield of healthy and viable offspring. Artificial egg incubation is widely used in modern farms, but traditional environmental control methods often ignore the influence of the lighting spectrum on the morphological and biochemical aspects of embryo development. Thus, an in-depth study of the effect of the red light spectrum on the growth and development of turkey embryos is relevant for practical implementation in modern technologies of industrial poultry breeding and increasing the economic efficiency of turkey meat production. The purpose of this work is to study the effect of the optical effect of the red spectrum on the linear length parameters of turkey embryos during incubation. The study is devoted to the analysis of the effect of red monochromatic light (wavelength 660 nm) on the growth of turkey embryos during embryonic development from 13 to 27 days. Embryo length measurements were performed on 13, 15, 17, 19, 21, 23, 25 and 27 days of incubation, which made it possible to track the dynamics of length changes under the influence of light exposure. According to the results of the study, it was determined that red monochromatic light had an effect on the length of turkey embryos on the 13th, 15th and 21st days of embryogenesis.
