Abstract
The article examines the impact of domestication and selection of fur-bearing animals on live body weight and the absolute and relative weight of some internal organs of three representatives of the mustelidae family (Mustelidae): mink, ferret and sable. During the work, the parameters of the liver, spleen, heart, lungs and kidneys were studied in females and males of each species. It was established that over the past period of domestication in minks (both females and males), the parameters of the considered internal organs increased manifold (from 1,84 to 2,70 times). In farm ferrets, regardless of gender, enlargement of the studied organs was also noted, but to a lesser extent (from 1,35 to 2,20 times). In farm sables, during cage breeding, the size of the liver (1,6 times in females and 1,1 times in males), heart (1,1 times in females and 1,2 times in males), lungs increased slightly – in females (1,2 times) and kidneys in females and males (1,2 times). The size of the spleen did not change and a decrease in the lungs was noted in males (0,9 times). Thus, it can be stated that in the species of fur-bearing animals under consideration, the process of domestication has an impact to varying degrees: the greatest in American minks and the least in sables.
