| Abstract |
Eight pigpens were visited twice during winter and once during summer to measure the concentrations of biological and chemical contaminants. For each of the premises, the cleanliness, number of ventilators, air temperature, number of animals and building size were noted. Air samples were taken to measure relative humidity, CO2, ammonia, total dust, microbiological counts and endotoxin levels. Significant decreases in bacterial levels, dust, ammonia and CO2 were observed during summer sampling when compared with winter levels. Mould counts were positively correlated with dirtiness scores, while bacterial counts were negatively correlated with this parameter. Bacteria and endotoxins were correlated with the number of animals. Ambient gases (CO2 and ammonia) correlated with each other. Bacteria were the most important contaminant in swine confinement buildings, and endotoxin levels found were also very high. |
