The definition of feed nutrients assumes the following: assessment of its chemical composition; estimate of the amount contained therein of digestible nutrients; estimate of the amount of energy released by them. We estimate the chemical composition of the components of the indices, which balanced diet. This seemingly simple requirement is not always fulfilled. In the practice of forage production are cases when during the chemical analysis of the finished feed is a discrepancy between the estimated and actual nutritional value, and with the same probability of deviation from the declared value of both in one and in the other direction. The database of contemporary programs for compiling feed rations contained digestibility coefficients of nutrients for all types of raw materials for all kinds of animals from the program of special factors, allow to balance feed rations on digestibility of nutrients and energy value component count. The paper proposes a mathematical tool for assessing the margin of variation of content of biologically active substances in the party regarding the premix recipe data. The reasons for the variations are considered random error methods of quantitative chemical analysis of biologically active substances (BAS) and random error estimates of the masses of carriers of active substances when they are dosed into the mixer.
