Drinking water for liquid-fed pigs
Published in 2017
Liquid feed can provide pigs with sufficient water to remain hydrated and prevent prolonged thirst. However, any lack of permanent access to fresh water prevents animals from drinking when they are thirsty. In addition, individual differences between pigs in a pen can result in the uneven distribution of water from liquid feeds, preventing some pigs from meeting their water needs. In this review, we examine the need for and provision of water for liquid-fed pigs in terms of production performance, behaviour, health and welfare. We highlight factors that may lead to water ingestion above or below requirements. Increased water requirements can be caused by several factors such as morbidity, ambient temperature or competition within the social group, underlining the need for permanent access to water, also provided for in EU legislation. Drinking animals may be the target of redirected behaviour in response to feeding restrictions or in the absence of rooting materials, thus leading to water losses. Water supply systems and the design of water troughs are essential components in ensuring easy access to water, regardless of the physiological condition of the pig, and in reducing water use, which has no benefit for the pig.
