Summary. Now extrusion processing of cereals and legumes is the most promising direction in the feeding of farm animals, which significantly increases the nutritional and biological value of the fodder. Authors studied the effect of the extruded fodder mixture SK-136 on the milk productivity of dairy Simmental cows formed on the basis of the pair-analogue pairs, equivalent in age, weight, productivity and physiological state. Positive effect of the use of extruded mixed fodder SK-136 was established in the course of the experiment. So, after 10 days of feeding with the extruded mixed feed, the difference in productivity was 2.3 kg, and after 20 days - 2.5 kg in favor of the experimental group. After 30 days, this difference was 5.3 kg, respectively. The fat content of milk during the experimental period was 3.5-3.6% in the control group, and 4.2% in the experimental group. During the entire experimental period, the live weight of the experimental group cows increased by an average of 26.4 kg, while the living weight of the animals in the control group decreased by an average of 11 kg. Thus, when feeding the extruded mixed fodder SK-136, the cows were quicker to gain average fatness, went on a hunt in time, fertilized and gave healthy viable calves. During calculating the economic efficiency of feeding extruded fodder SK-136, it was found that 16,80 rubles of net profit were received from each cow of the test group per day.
