Biochemical status and composition of cow’s milk when feeding them with oil seeds

False flax (Camelina sativa (L.) Crantz) is a promising oilseed crop for use in animal husbandry. The aim of the work was to determine the physiological status of cows and the biochemical composition of their milk under the influence of feeding micronized seeds of Camelina sativa. In the Tambov region, 2 groups(control and experimental) of Simmental cows(live weight 500 kg, daily milk yield 18 kg) were formed in accordance with the requirements for the selection of analogues in a breeding reproducer. The experiment was carried out in the stable period after 1.5…2 months after calving of animals aged 2…3 lactation. For balancing the ration of cows of the experimental group in terms of protein and energy content were used seeds of Camelina sativa, previously heat-treated (by micronization), in the amount of 5 % by weight of the grain mixture. Biochemical parameters of animals’ blood and milk composition were studied in the experiment. In cows that consumed false flax seeds in the diet, protein-carbohydrate and fat metabolism were more intense. The concentration of glucose in their blood was higher by 0.26 mmol/l, total cholesterol – by 0.64 mmol/l, alanine aminotransferase activity (AlAT) – by 12.07 U/l, urea content-lower by 1.44 mmol/l. The mass fraction of fat in milk under the influence of feeding ginger seeds increased by 0.35 % compared to the traditional diet. At the same time, the content of such especially valuable unsaturated fatty acids as linoleic acid (up to 1.3 times) and linolenic acid (up to 2.7 times) increased in its composition.
