Fatty acid composition of cow milk fat under the influence of humic acids

Abstract

The article investigates the effect of an organic feed mixture based on humic acids on the mass fraction of fat and the fatty acid composition of cow milk. It was found that the introduction of the mixture into the diet at a dose of 20 g/100 kg of body weight contributes to a significant increase in the fat content in milk 65 days after the correction of feeding. Changes in the composition of saturated and unsaturated fatty acids were detected, in particular an increase in the content of heptadecanoic and stearic acids, which may be associated with the activation of rumen microflora under the influence of humic acids. The results obtained indicate the possibility of correcting the quality indicators of milk by using organic feed additives.
