During the summer months, we will generally see a sow’s discomfort at the high temperatures reflected in her behaviour – resulting in decreased appetite, a reduction in feed intake, and a drop in milk production, which causes negative effects on piglet performance and maternal performance.
Two different microclimates are maintained in farrowing rooms – one for the piglets (between 30 °C and 35 °C during the first week of life), and another for the sow (ideally between 18 °C and 20 °C). It is, therefore, very difficult to control and maintain the temperature for each, so the sow is often subjected to temperatures well above the recommended range.
To achieve this balance, a farm called HoCoTec, located in the Colombian tropics, has implemented the FRESHNOSE system to improve the thermal comfort of the sows. The FRESHNOSE system uses a small air stream at the sow’s nose so that the area surrounding her head is at a temperature of 22 °C, while in other parts of the pen it can be around 33 °C. This contributes to improving the sows’ thermal sensation, feed intake, and litter performance, among other things.
