In the conditions of the Republic of Belarus there was analysed the problem of methionine deficiency and determined the efficiency of application of a fodder additive MHA (TM) (containing 84% of calcium salt of methyl-phosphonic acid of 2-hydroxy-4-methylthiobutanoic acid) for broiler chickens feeding. The research results showed that the fodder additive MHA (TM) possessed a wide spectrum of fermented activity, promoted to the increase of uptake of forage fibers and activated its synthesis in organism of chickens, as well as stimulated the process of digestion, promoted fuller uptake of forages nutrients, reduction of their expenses. The average energy value made 2.06 mJ/kg. After administration of the analysed fodder additive there was marked tendency of increase of crude protein level in blood serum of broiler chickens on 1.7%. Together with increase in the content of crude protein in chickens of the experimental group there was marked the increase of albumen on 9.5%. Albumins were synthesized in chicken liver and increase of their quantity (within the limits of physiological norm) can prove the positive effect of the fodder additive on function of a liver. Application of the fodder additive caused the increase additional weights. The difference in weight gain between groups has made more than 3%.
