Abstract
Ginger seed (Camelina sativa (L.) Crantz) is a promising oilseed crop for use in animal husbandry. Ginger seed oil contains a large amount of fatty polyunsaturated acids, which are an indispensable component of nutrition, as they participate in many biochemical reactions of the animal body. The study of the content of fatty acids in ginger seeds after their heat treatment by micronization, which were later used in experimental feeding of dairy cows. An advanced device for heat treatment of grain and beans was used for micronization of seeds. Several processing modes were used depending on the number of halogen lamps included. A study of the quantitative composition of fatty acids in the milk of cows fed with heat-treated ginger seeds was carried out. When using one or two cassettes with halogen lamps during temperature treatment, the ratio of the total amount of saturated and unsaturated fatty acids in seed oil does not change significantly. The content of palmitic acid after treatment increased by about 8%, stearic acid – by 3%, linoleic acid – by 2%. The content of oleic acid decreased by 3%, eicosenic acid – by 1%. The feeding of heat–treated ginger seeds to dairy cows as part of the feed mixture did not significantly change the species composition of fatty acids in milk, but contributed to an increase in the amount of some particularly valuable fatty acids for the body - linoleic (1.3 times) and linolenic (2.7 times).
