Abstract
The scientific work deals with the problem of the influence of limited motor activity (hypokinesia)
on the somatic systems of the animal body, in particular, Peking ducks were the biological object
of the study. The results of a study of the effect of 60-day hypokinesia on the skeletal musculature
of ducklings from birth to 2 months of age of postnatal ontogenesis are presented. In the course of
research, it was found that up to 15 days in most muscles, the relative mass index decreases with
age, and subsequently increases in correlation with the development of somatic and visceral systems,
which indicates the continuation of adaptive processes during this period of ontogenesis. At
the same time, the lag in the growth of the muscles of the ducks of cellular content, we noted only
on the 60th day. Walking ducks, having more space to move in space, additional movement in the
form of bathing in a pond, increased muscle mass more actively, compared with their experienced
counterparts who are in conditions of limited motor activity. Linear muscle indicators also respond
to the effects of hypokinesia and are expressed in the manifestation of a tendency of their lagging
behind the control ones, which eventually led to a significant difference in morphometric indicators,
at different times of the experiment.
The results obtained are basic in the formation of the concept of muscle morphogenesis in poultry
meat productivity and can be used by specialists in improving the technologies of breeding work.
