Abstract

The aim of the research was to study the dry palm oil «Profat» effect on the young short-haired mink skins quality during the winter hair cover formation (OctoberNovember). The experiment was carried out on slaughter young animals in the Corporation «Saltykovsky fur farm» of the Moscow region. It was found that the introduction of a new vegetable fat source into the slaughter young animals diet in the amount of 0.75g per 100g of feed mixture provides an increase in the absolute and relative increase in live males weight of the experimental group by 80.4 g (2687.1 g vs. 2611.5 g in the control) and 3.1% (21.2% vs. 18.1% in the control), respectively. When assessing the internal organs condition of animals, no pathological changes in their development were detected. Based on the analysis of data on the size and quality of the slaughter young males skins, it was found that the inclusion of dry palm fat in the diet provides, in comparison with the control group, an increase in the skins area in the experimental group by 0.2 dm2 due to an increase in the proportion of skins of sizes 30 and > and 0-20 by 9.4% and a decrease in the proportion of smaller skins – 1 and 1+ by 9.4%, an increase in the size offset by 1.7%. The economic efficiency of using palm oil in the young mink diets during the formation of winter hair cover (OctoberNovember) amounted to 27.0 rubles per skin (in 2020 prices) at the drug cost 0.21 rubles.
