The relevance of work In conditions of intensification of sheep husbandry, the requirements for obtaining the greatest amount of high-quality wool, sheepskin and meat are substantially increasing.The most complete realization of the potential for sheep productivity is possible only under conditions of optimal feeding, balanced in all nutrients, including amino acids. When feeding sheep, methionine is the most important essential amino acid. It was found that amino acids undergo partial degradation under the influence of rumen microorganisms. [Aliev A.A. 1997, Dvalishvili V.G. 1989, Zlydnev N.Z. 1993, Kryazheva V.L. 2002, Sevastyanova N.A. 1974, Tkachenko M.A. 1985]. This problem can be solved by feeding methionine to ruminants in a “protected form in order to prevent splitting.
