In the conditions of the Republic of Belarus there were presented the results of a veterinary and sanitary assessment and bacteriological investigation of sheep slaughter products, which showed meat serviceability for consumption after application of Triclafen suspension. Application Triclafen suspension did not render negative influence on an organism of animals. It was proved by organoleptic and laboratory research of meat of slaughter animals of experimental and control groups. The meat obtained from healthy sheep which were administrated the suspension in accordance with microbiological indicators proved to be of good quality and corresponded to the established norms (Sanitary regulations and standards 11 - 63 Republic of Belarus 98): it had the general bacterial content within admissible limits and did not contain agents of anthropozoonosts, alimentary toxicosis and toxinfections and it can be sold without any restrictions.

In the conditions of the Republic of Belarus there was studied the influence of electroactive solutions of anolyte neutral, catholyte alkaline and hypochlorite sodium on microbial flora of a gastro enteric path of calves and sheep. In course the realized research it was stated that more expressed action of anolyte neutral and hypochlorite sodium on beneficial microflora of animal intestines (namely, the decrease in quantity of some indexes) can probably be explained by an expressed antimicrobic action of the analyzed solutions. However, the quantitative changes occurring in composition of microbial flora were not so great and cannot cause radical changes of a microbial landscape of gastro-intestinal tract. Less expressed influence on microbial flora of intestines of calves and sheep rendered the solution of alkaline catholyte. Taking into consideration the expressed regenerative properties of the studied electroactive solution, it was possible to assume, that according to the mode of action of the preparation, its application will promote the increasing of protective forces of an organism without causing any radical changes of a microbial landscape of intestines of animals. The problem of influence of electroactive solutions on a microbial landscape of a gastro enteric tract of animals demands the further studying, however at the given stage it is possible to make a conclusion, that the quantitative changes of the microbial flora which were caused by application of the analyzed solutions, proved to be less fatal and did not render sharp negative influence on a microbial landscape as a whole. Taking into consideration data of the realized research it is possible to make a conclusion on possibility of application of the electro activated solutions of anolyte neutral, catholyte alkaline and hypochlorite sodium for treatment of gastro enteric tract diseases of agricultural animals.

Disinfection of cattle-breeding farms and their equipment is an action directed towards eradication of causative agents of infectious diseases in environment, towards the liquidation of the infection focal points as one of epizootic chains by means of application of various chemical substances. Study of the corrosive activity of developed in Belarus disinfectants and their comparison with the foreign analogues was realized. Cattle-breeding premises possess considerable metal consumption. Traditional disinfectants possess the expressed corrosive action and cause the substantial deterioration and damage of metal structures of premises. In recent years there were developed and recommended for application in veterinary science some new nontoxical, ecologically safe disinfectants, developed with the assistance of scientists of the S.N. Vyshelesskij Institute of Experimental Veterinary Medicine of Belarus, such as: Virkotsid (technical specifications BY 190245337.001-2007), Sandim-D (technical specifications BY 100917107.001-2007), combined disinfectant of surfaces, Valisan (technical specifications BY 101385752.001-2006), Belopag (technical specifications BY 100162869.059-2005), Belsteril (technical specifications BY 500027013.001-001-2003) and Vitmol (technical specifications BY 300047997.001-2003). Research results showed that the analysed disinfectants possessed less corrosive activity to metals in comparison with the foreign analogues (Glutex, Dezavid, Virkon C, etc.). The least severity of corrosion was stated in the disinfectants representing the compositions of the bactericide agents (Sandim-D, KDP, Belopag, Vitmol, Virkotsid, Valisan, etc)
