[Microbial content of the air in poultry houses]

The industrial animal-breeding complex is characterized as an ecotechnical system the function of which is determined by the action of antropogenic factors. It has been demonstrated that up to now the stress of antropogenic activity has been laid on the optimization of the abiotic factors. The control and optimization of the biotic factors has constituted a problem for industrial poultry breeding, especially important being the microbial content of air. Investigations have shown that with the industrial raising of birds air microbism has assumed the importance of a factor that lowers the effectiveness of the technologies applied. The factors have been discovered that govern the extent of microbial contamination of air. Results of experiments in productional poultry houses and climatic chambers have led to the offer of measures aimed at limiting the microbial contamination of air in the industrial raising of birds.
