This article presents studies showing that in order to reproduce the herd and obtain competitive furs, it is necessary to form a herd of breeding sable, mostly consisting of a herd of females aged 4-10 years and older. The studies were conducted on the sable farm of the fur farm ZAO "Biryuli" of the Vysokogorsky district of the Republic of Tatarstan. Five groups of females of different ages were formed: 1 year, 2 years, 3 years, 4-10 years and over 10 years. Males of the middle age category (4-10 years) were selected as producers. It was found that the duration of pregnancy in first-year females was shorter (277 days) than in all other age groups. Females with the shortest pregnancy period (one-year-olds) have a number of low reproductive indicators and a high level of barrenness (35 %). The largest total number of puppies is produced by females aged 4-10 years and older, although they are characterized by a large number of stillborn puppies (the proportion of dead puppies in these groups ranges from 6.5 to 12.5 %). The data obtained indicate that females aged 4-10 years have the highest fertility with the least number of absent females and females with dysfunctional childbirth. Reproductive indicators of sables depend on their age.
