Popis: Due to increasing litter size at weaning, the stocking density in the nursery phase has increased and feeder space reduced. Understanding how both factors work is potentially relevant to reduce the negative implications for piglet growth performance and welfare. A 3 × 4 factorial arrangement with 2160 pigs was used in a 42-day study to investigate the effects of floor space allowance (0.15, 0.25, and 0.35 m2/pig) and feeder space (1.6, 3.2, 4.8, and 6.4 cm/pig) on growth performance, and tail and ear lesions in nursery pigs at a commercial farm. Pen dimension provided 0.35 m2/pig, and divider fences were used to provide 0.15 and 0.25 m2/pig, with 20 pigs per pen for all treatments. More pigs were removed in 0.15 than 0.25 and 0.35 m2/pig (P 380 g/day, > 22.5 kg, and > 440 kg, respectively) were obtained with floor space ranging from 0.25 to 0.35 m2/pig, and feeder space from 4.0 to 4.4 cm/pig. Furthermore, low ADG (
