The results of the content of feed in ration of cattle in the Podillya region of Ukraine are presented. It was found that among the green fodders, the highest content of selenium was observed in alfalfa (0.073 mg / kg SR), peas and oats (0.060 mg / kg), oak vetches (0.057 mg / kg) and clover (0.057 mg / kg). In contrast to hay, a fairly high concentration of selenium - 0.135 and 0.114 mg / kg SR respectively - was observed in such rough feeds that are derivatives of sunflower, in particular baskets with the upper stems and husk. The higher content of this element is characterized by silage from a mixture of corn and sunflower (0,067 mg / kg), as well as silage from a hive of sugar beets. The least selenium is contained in silage from corn stalks without swollen - 0,039 mg / kg SR. The highest grain selenium in soya (0.101 mg / kg) and peas (0.098 mg / kg), and the least - in wheat and sorghum (0.054 and 0.060 mg / kg). Attention is drawn to the level of selenium in soybean and sunflower meal - 0.145 and 0.139 mg / kg, which is even higher than in soybean and sunflower meal and in grain feeds. The high content of selenium is noted in animal feeds, and from them - in meat-bone meal (0,231 mg / kg) and dry milk (0,112 mg / kg). Regarding the content of selenium in feed for cattle, it was on average 0.088 mg / kg. The dry pulp on the level of selenium yielded 0.012 mg / kg before the feed (0.076 vs. 0.088 mg / kg)
