CONTENT OF VETERINARY PREPARATIONS IN SEWAGE OF PIG FARMINGENTERPRISES
Introduction. Introduction of animal products intensive production technologies resulted in creation of potent industrial complexes that house significant livestock, especially pigs, on limited territory. The latter involves formation and accumulation of significant amount of liquid waste during pork production mainly consisting of urine, intestinal wastes and industrial water.Thus, arises problem of animal waste pollution control, as well as development of efficient measures for animal liquid waste processing to the extent of environmentally safe products.The goal of the work. To determine residual amount of pharmaceutical preparations in intestinal wastes and manure sewage of number of pig farming enterprises using different types of pigs feeding (concentrated and combined) and various systems of manure removal.Materials and methods. Researches were conducted during autumn and winter period of housing. Three technological groups of pigs were formed. Average samples of manure sewage were taken from each group and tested for residual veterinary preparations and animal productivity stimulants.Results of research and discussion. Research results showed that wastes of pig farming enterprises contain a range of veterinary preparations as well as bioactive compounds that areused as pig productivity stimulants. Moreover, certain amount of these compounds forms inside animals’ body to provide physiological functions and metabolic processes in organs and tissues.Conclusions and prospects for further research. It was established that wastes of pig farming complexes contain sulfanilamide, sulfamethazine, albendazole, tetracycline, boldenone and nandrolone.Considering that transfer of remaining veterinary preparations with antimicrobial properties into wastes of pig farming enterprises may have significant effect on processes of evolution of organic matter, study of microbial associations that provide aerobic biofermentation and biomass anaerobic fermentation and main ways of waste biological treatment is promising. Studies of effect of antihelminthic remains in manure sewage on waste composting processes while using vermiculture, as well as splitting dynamics of detected remains of veterinary preparations and hormones, their cumulation, migration and transformation ability in biological chains and ability to effect feeds and human food products safety is also important.
