The Federal Antimonopoly Service (FAS) of Russia is conducting a study on the pricing of feed components for farm animals. This includes gathering information on production volumes, sales, cost price, wholesale prices, and profitability of sales. The agency will respond appropriately if antimonopoly legislation is violated. Websites of lysine producers have previously been contacted by the FAS. Soybean meal, a by-product of oil extraction from soybean seeds, and lysine, an essential amino acid used in feed, are under investigation.
