Bacteriological Examinations of Air in Sheep Folds,
Abstract
Studies were made to define the degree of bacterial air pollution in sheep folds in differentiating microclimatic conditions. Bacteriological and microclimatic examinations of the air were performed in Feb 75 in 12 halo-type sheep folds in which merino sheep were kept. The following are among the authors conclusions: (1) The number of microbes in the air of the folds increases in parallel to the increase in temperature and relative humidity; (2) In folds equipped with working exhaust and gravitational ventilating systems, the number of microbes in the air is somewhat lower in comparison with folds having approximate microclimate conditions, not having ventilating systems; and (3) In folds with optimal air temperature, high humidity and large number of microbes, the index of morbidity and fatalities in sheep is considerably higher than in folds with lower temperature and humidity as well as a smaller number of microbes.
