Journal Title: Бюлетень "Ветеринарна біотехнологія" - Year 2018, Vol 32, Issue
Abstract
Introduction. Poultry eggs production intensive technologies is widely use antibacterial preparations of different groups to combat and prevent poultry diseases. These preparations excrete with droppings and accumulate in poultry products and thus, they are pollutant that carries risks for environment and people health. The goal of the work was determination of antibacterial preparations content in chicken droppings of industrial flock with intensive production technologies. Materials and methods. Research was conducted on the basis of State Research Institute of Laboratory Diagnostics and Veterinary and Sanitary Expertise. Subject of research was chicken droppings of industrial flock of high-line white cross from two different poultry farm of Ukraine. Sample of droppings were taken from three different places of each aviary. The mass of samples was 300-500 g. Content of antibacterial preparations in chicken droppings was determined by routine methods using of liquid chromatograph with the mass-spectrometric detector, Waters (USA) according to the manufacturer manual. Results of research and discussion. The conducted researches revealed that the chicken droppings of industrial flock contained residues of veterinary preparations. In chicken droppings from the first farm doxycycline was detected at aviary No. 1, 4, 5, 9 and 11 in concentration ranged from 11.22±0.14 to 18.82±0.06 mkg/kg. In chicken droppings from aviary No. 2, 3, 7, 10 and 13 as enrofloxacin detected in concentration ranged from 35.55±0.1 to 71.43±0.24 mkg/kg. At the same time in chicken droppings from aviary No. 6, 8 and 12 any veterinary preparation was not detected. In the second farm it was detected doxycycline in chicken droppings from all twelve aviaries in concentration from 21.61±0.08 to 318.82±0.19 mkg/kg. At the same time enrofloxacin was detected in samples from aviary No. 2, 4, 6, 8, 9 and 12 in concentration from 51.14±0.13 to 278.64±0.21 mkg/kg. It was shown that the most widely used antimicrobial preparations in chicken production are antibiotics of tetracycline and fluoroquinolone groups. Conclusions and prospects for further research. Residual content of doxycycline, enrofloxacin, and their mix in the chicken droppings varied, which could be related with used antibiotics, their duration of application, and the period of excretion from the organism. The residual amounts of veterinary preparations in chicken droppings are not regulated and that is why they are uncontrolled pollutant of the environment.
