摘要：

In this experiment negative effects of non-continuous daily draught were observed when newly weaned pigs were submitted to this regime in an unpredictable and uncontrollable way for 6 weeks. Negative effects were observed in production (decreased growth rate), clinical parameters (increased coughing, sneezing, diarrhoea, skin lesions) and subclinical parameters (more severe pneumonic lesions). Therefore it can be concluded that draught should be avoided under practical conditions. Thereby, production efficiency could be improved, as shown in this experiment in which daily gain under optimal conditions was extremely high (700 g/day between 5 and 10 weeks of age) and clinical and subclinical signs were minimal.
