APPLICATION OF THE PRINCIPLE OF ALLOMETRY TO CALCULATE THE GASTRIC MASS IN JAPANESE QUAILS

Using allometric equations, one can theoretically determine the anatomical constants of representatives of the class of birds and mammals, identify significant differences in the dynamics of these indicators, and determine which morphophysiological parameters do not obey these relationships. Thus, the principle of allometry allows, on the one hand, to identify and justify the general model of the structure and functioning of the animal organism as a whole, and on the other hand, it creates a basis for assessing the quantitative and qualitative deviations of individual species of birds and mammals from this model. The study was carried out in the experimental research laboratory and vivarium of the Department of Veterinary Medicine of the Agrarian and Technological Institute of the Peoples' Friendship University of Russia in the period from 2019 to 2022. The aim of the study was to develop an allometric equation of the stomach, reflecting the processes of its formation and allowing to reveal the relationship between its shape and structural elements that determine its internal architectonics. The article presents the results of experimental studies of weight indicators of the stomach (absolute and relative weight) in Japanese quails in early post-incubation ontogenesis, on the basis of which a new original allometric equation is proposed that takes into account the age factor. Allometric equations make it possible to non-standardly evaluate and calculate anatomical constants for a particular animal species. Thus, knowledge of the anatomical features of the digestive system of Japanese quails makes it possible to purposefully influence their growth and development, using breeding and selection in the right direction to maintain the health of the animal.
