In the conditions of the Republic of Belarus there was studied the effectiveness of the use of by-products of corn starch in the diets of dairy cows. Length of the first and second experiments was 60 days. Cows in the control group received the basal diet used in the farms, which consisted of hay, silage, hay and concentrated feeds. In the first experiment, the experimental group of cows in the diet part of the concentrates was replaced with raw corn feed, in the second experiment - dried corn feed. Inclusion of data feeds in the diet of dairy cows improved the average daily milk yield at 3.3–6.1%. The use of wet and dry corn fodder has led to a decrease in the cost of rations and the cost of milk. Reducing the cost of milk production rendered positive effect on the increasing of profits from the cows of the experimental group, which was based per a head on 252.7–345.8 thousand Belarusian rubles for the period of the experiment.
