    abstract = {The objectives of this study were to determine whether provision of additional water via wet/dry feeders, and use of chains as distractors, improves performance and reduces ear biting in nursery pigs. The study was based on a 2 ? 2 factorial design, with provision of additional water in wet/dry feeders and chains as the main factors. A single nipple drinker was provided in each pen of 35 to 40 pigs. In 36 of the 66 pens, wet/dry feeders were not connected to the water line, and in 30 pens, wet/dry feeders provided additional water. Chains were provided in alternate pens. Pigs were individually weighed and assigned an ear score at weaning (approximately 3 wk of age) and at approximately 8 wk of age. Piglets in 48 pens were videotaped for 24 h on days 7, 14, and 21 post-weaning, using black-and-white time-lapse video equipment. The numbers of pigs drinking, feeding, and interacting with the chain were recorded. There was less variation in ADG (P<.001) in groups with additional water. The incidence of ear lesions was lower in pens with a chain (P=.01) and higher in heavier pigs (P<.01), but was not affected by use of wet/dry feeding (P=.53).}
