The tropical environment constantly subjects heat-sensitive farm animals to stress under warm environmental conditions. Animals exhibit different behavioural patterns in an attempt to cope with the stress. However, the level of stress susceptibility varies from one animal to the other. The effects of heat stress are easily noticed in the physiology of the animal and it generally reduces productivity of the animal. In order to alleviate the problems associated with manual wallowing to reduce heat stress in pigs, an automatic showering system was designed, constructed and evaluated. The system is such that the movement of the pig through the entrance of the shower will trigger a pump with the aid of an infra-red electronic device. The pump will supply water to the shower head and subsequently effect cooling of the pig. The system is very efficient as the delay period only varied from 1.7 s to 2.59 s and the pump discharge was 0.2 litres/sec. The showering period to cool the pig was 4 minutes. It was concluded that the system could be adapted for use by pig farmers for reduction of heat stress and hence improve productivity.
