Аннотация:It is necessary to estimate economic efficiency of operation in agricultural enterprise of mobile formula-feed unit in comparison with stationary enterprise for conditions of Russia. The required capital investment for the purchase of a mobile unit and its payback period is significantly less than for a stationary plant of the same capacity. Its economic efficiency is, however, lower than that of a conventional formula-feed plant. The operating costs of a mobile unit are 18% higher and the prime cost of feed is 0.7% higher than that of a stationary formula-feed plant. The profitability of production for the mobile unit is 0.7% and the net present value is 6.7% lower than for the stationary plant. Mobile units and stationary small-scale formula-feed plants have their own scopes of application in small-scale and medium-scale agricultural enterprises where they will be economically efficient. A mobile unit is cost-effective if there are several dispersed livestock farms and raw material storage places on the agricultural enterprise. If the agricultural enterprise has one livestock farm and one raw material storage place, a stationary conventional plant is more cost-effective.
