From 2010 to 2015, a short-haired mink from Denmark and Poland was imported to the Savvatievo Animal Farm, which is large in size compared to the domestic one. To preserve and further increase the size of the mink, in addition to breeding work, the feeding standards were revised. Since 2010, new non-traditional feeds have been introduced into the diet of animals, the nutritional value of which is not known yet, the caloric content in 2015-2017 was increased to 165-170 kcal and by 2018-2021 it was brought to 180 kcal per 100 g of feed, while at the same time gradually reducing the amount of protein: in 2015-2017 to 7.5 g and in 2018-2021 to 6.5-7.0 g per 100 kcal of feed for young animals during the growth period (July-October). Feed with a high fat content is introduced. In this regard, it was decided to conduct a detailed analysis of some non-traditional feeds by fatty acid composition and determine the effect of the introduction of these feeds on the growth of young animals.
