Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 4, Issue 4
Abstract
The peculiarities of accumulation of antibiotics in chicken manuare of industrial and repair herds are established when they are used for therapeutic purposes. It was revealed that the residual amount of amoxicillin in the litter of hens of the industrial herd is at the level of 12.22 to 121.96 μg / kg, in the manuare of the repair herd of cocks - 19.45 mkg / kg and the repair herd of chickens - 28.94 mkg / kg. Keeping the manuare of commercial hen herds under mesophilic conditions promoted an increase in the concentration of amoxicillin to 276.3-337.3 μg / kg of litter, which practically reached one level in samples taken at the ends and center of the poultry house. The presence in the manuary of commercial herds of a residual amount of oxytetracycline, amoxicillin and colistin promotes an increase in the level of amoxicillin in the litter during its mesophilic storage in 1,2 - 7,5 times in comparison with the initial concentration. The presence in the chickens manuare of the repair flock amoxicillin in conjunction with colistin helps to ensure a stable concentration of amoxicillin for 17 months of storage under mesophilic conditions. If there is only amoxicillin in the manuare of the repair herd of cocks, its residue has decomposed in the environment for 3 weeks.
