BIOLOGICAL REGULARITIES OF MUSCLE MASS CHANGES IN THE PERIPHERAL REGION OF TSIGAI LAMBS
The article deals with the study of specific features of growth and development of the basic sectors and individual muscles in the peripheral region of Tsigai lambs at different age periods. The young rams, ewe lambs and young wethers were included in the study. It is found that different intensity of the pelvic and thoracic limb muscles increase is mostly conditioned by different average monthly growth of muscle tissues mass. The standard muscle groups differ in growth rate with different age periods of the animals' development. The growth dynamics in a given group is determined as the total of growth parameters of individual muscles of a certain group, though some muscles have their own specific growth pattern, which is distinguished from that of other animals of the group.
