Abstract

After 14 h of confinement in a stationary trailer, sheep were found to have lost proportionately a mean of 0·057 of their body weight. Two experiments, one with a heterogeneous flock (28·6 to 93·2 kg body weight) and the other with a more homogeneous flock (32·4 to 46·6 kg) showed very little recovery of this loss after 1 h of ad libitum food and water. When offered familiar concentrates, sheep ate on average 1·2 kg per animal in the 1st h, water only being taken in quantity (>5·01 per animal) in the next 6 h. Hay was taken at a much lower rate (0·25 kg per animal) and less water drunk (1·51 per animal). Competitive social interactions were five times more frequent during hay feeding than during concentrate feeding. After 14 h of confinement a break of Ih is evidently insufficient for feeding and watering and could result in poor welfare. If concentrates are offered, the resulting water deficit will not be redressed within 1 h, resulting in a strong motivation to drink when no water is available. If hay is offered, the heightened level of competitive social interaction could also result in poor welfare.
