Some cattle sloughed 1 or more hoof walls while in lairage pens and were euthanized. Other cattle recovered after being rested overnight. Affected cattle had serum lactate concentration and creatine kinase activity increased from reference ranges. \r\n\r\nHistologic findings included diffuse necrosis of the epidermal laminae with degenerate collagen and perivascular infiltration of neutrophils in the underlying deep dermis, and were similar for digits that had and had not sloughed the hoof wall. With the exception of the sloughed hoof walls, the clinical signs and serum biochemical abnormalities observed in affected cattle were similar to those observed in pigs with fatigued pig syndrome, and we propose that fatigued cattle syndrome be used to describe such cattle. \r\n\r\nAlthough anecdotal evidence generated concern that cattle fed the \u03b2-adrenergic receptor agonist zilpaterol hydrochloride were at greater risk of developing mobility problems, compared with cattle not fed zilpaterol, this condition is likely multifactorial. Strategies to prevent this condition are needed to protect the\u00a0welfare\u00a0of cattle. \r\n\r\nThe study is from the College of Veterinary Medicine, Kansas State University, Kansas, USA; College of Agricultural Sciences and Natural Resources, Texas Tech University, Texas, USA; College of Veterinary Medicine, Iowa State University, Ames, Iowa, USA.\r\n\r\nThomson DU,\u00a0Loneragan GH,\u00a0Henningson JN,\u00a0et al. <em>J Am Vet Med Assoc<\/em>\u00a02015; 247(1): 66-72.
