Determination of the positive aspects of application of a feed additive on the basis of sodium humate and malt sprouts fortified with oaky extract in diets of high-productive cows in dry period was realized in the conditions of the Republic of Belarus. Cows of black-and-white breed with average body weight 600 kg and milk-yield 6000-7000 kg were used in the experiment. Cows of experimental groups in addition to their main diet were fed with the resolved additive in doses 10-20 ml/100kg of live weight. Formula of humic additive with draft name Ehkolin-3 was developed on the basis of Ehkolin additive. Ehkolin additive in its composition contained the following compounds: organic substances; mineral substances; humic substances; melanoids; reducing agents; phenolic compounds; organic acids, and total nitrogen. Research results showed that application of the analyzed additive promoted the increasing enzyme activity in blood serum. Body weight of new born calves in experimental groups was higher than in control group. Symptoms of diseases of the digestive tract disappeared in 4-5 days in the experimental calves. Cows of the experimental groups had good colostral milk with density 1056 kg/mE3 and 55% of immunoglobulins. Impregnation capacity of in one experimental group was 50% after the first insemination, and only 33,3% and 20% in the control and the second experimental group, respectively
