ABSTRACT:
This paper reposts the results of the study of the structural features of the enteric nervous system of a multi-chambered stomach in lambs of the Edilbay breed, which were grown using artificial feeding with the use of a sheep milk substitute. Neuromorphological and morphometric methods of research were used. The paper also presents comparative data on the development of neuronal processes (axons and dendrites) during the early postnatal ontogenesis of ganglia of the rumen, reticulum, omasum, and abomasum in ruminants due to adaptive rearrangement under the influence of the feed and growing conditions. The obtained data provides a better understanding of the specific features of the development of intermuscular ganglia in the multi-chambered stomach and allows to analyze their adaptive rearrangements during artificial feeding of lambs in combination with the traditional way of housing and feeding. This will help to determine the mechanisms of progressive and regressive development, as well as the maximum implementation of the biological capabilities of the body of ruminants.
