Description
Results of internal environment integrated production system research with the point of view of qualitative analysis and risk evaluation were casted in the article. In particular, model and method of calculation of integral index of production vertical line risk and improved data-flow model of effectiveness assessment of IPS with an account of risk constituent on the stage of creation of material flow are described. Reasonability of presentation of prognostic meaning of profit in the type of indistinct triangular number was substantiated.

Description
Application of peptide feeding additive from tanning production wastes (PFA) in volume of 3% to the ration and succinate in dose of 25mg/kg from net weight during the whole period of fattening influences on activity of ATPase of nuclear and cytoplasmic membranes of erythrocytes, processes of amino acids transportation, energy exchange, protein biosynthesis. Feeding with PFA doesn’t bring about to essential changes of physiological condition and is attended by increase of net mass on 7,6%.
