Object of research: dry forages for unproductive animals, laboratory animal (white mice), infusorians (Tetrachіmena pіrіformіs, Colpoda steіnіі). Purpose of research: veterinary-sanitary and quality standard of dry forages for unproductive animals who are realized in a trading network, during their storage and realization, improvement of methods of veterinary-sanitary examination of dry forages for unproductive animals in conditions of the state laboratories of veterinary-sanitary examination, system engineering of monitoring of quality and safety of dry forages for unproductive animals and a substantiation of its economic efficiency. Methods of research: organoleptical, biochemical, microbiological, research on the contents of toxic elements and radionuclide, mathematical. Scientific novelty: for the first time quality and safety of dry forages for unproductive animals who are realized in a trading network during their storage and realization is investigated. For the first time classification of dry animal forages for unproductive animals is developed in view of their fodder and biological value, a toxicological express train - method of monitoring of safety of dry forages for unproductive animals with use of infusorian Colpoda steіnіі. The system of monitoring of quality and safety of dry forages for unproductive animals, according to the international requirements of system of parameters of safety НАССР is developed and offered. Degree of introduction: for quality assurance and safety of dry forages for unproductive animals in laboratories of veterinary medicine to use the complex system of the veterinary-sanitary control advanced and scientifically proved by us. The suggested monitoring system includes three interconnected steps of the control. At the first step carried out the following researches: organoleptical, with use of test of cooking; microbiological, with use of the suggested express trains - methods of definition GBO, enterobacteria and salmonella; researches on the general toxicity, with application of the advanced microbiological express train - method with use of infusorian Colpoda steіnіі; research on the contents radionuclide. An estimation of results of researches to spend as follows: at conformity of all researched parameters to sanitary norms to count a forage qualitative and safe and to suppose in realization. If by results of organoleptical researches the forage is attributed to a category of doubtful quality, to pass to the second step - to carry out biochemical researches, with definition of the general acidity, amino-ammoniac nitrogen and carrying out of reaction with reactant Nesler. At definition by results of biochemical researches of a forage as qualitative or doubtful quality, research to continue according to the circuit of the first step of the control. If the forage by results of biochemical researches is determined as poorquality, research to stop and all party of a forage to send for processing. At revealing at the first step of the control of a forage of the general toxicity to pass to a third step of the control - to carry out research on the contents of separate toxic elements - lead, cadmium, arsenic, mercury, copper and zinc, for definition of the reason of toxicity. But irrespective of result of researches to count a forage poorquality and to send on recycling. Sphere (field of using): veterinary medicine.
