Experiment was carried out in 6 groups of Ukrainian dairy black-and-white cows of 5 animals in a group. Cows were divided into 2 subgroups of 15 animals, each of one formed 3 groups: 1 control and 2 experimental. The diet of the first subgroup contains a soybean meal, and the second – a similar amount of soybean cake. To the ration of cows of 2-nd and 3-rd group propylene glycol or new developed dietary supplement were added. The trial lasted during the last month of the dry period and the first month of lactation. Addition of propylene glycol increased the concentration of glucose in the cows blood plasma (P < 0.05). Adding propylene glycol to the diet with soybean meal reduces the triacylglycerol content in the plasma by 21.22% (P < 0.05), addition of complex supplement to this diet, on the contrary, increases the content of triacylglycerols by 21.21% (P < 0.05). On the diet with soybean meal, propylene glycol and complex supplement reduced the amount of non-esterified fatty acids by 14.29% and 21.43% (P < 0.05), while with the soybean cake diet these differences were 21.22 and 40.39% (P < 0.05–0.001). Under the influence of feeding propylene glycol and the complex supplement, the total amount of ketone bodies in the blood plasma of cows consuming the soybean meal diet decreased 1.65 and 1.75 times (P < 0.001), and in the plasma of cows fed soybean cake diet 1.71 and 1.80 times (P < 0.001).
