Many veal calves arrive to growing facilities with diseases, including diarrhea and navel inflammation. Observing neonatal calf behavior, such as lying behavior, can be used to better detect and determine the implications of these diseases. The aim of this study was to determine the effect of navel inflammation and diarrhea on lying behavior in neonatal veal calves. This study was part of a larger experiment that included a total of 360 male Holstein calves from 3 cohorts; from these calves, we selected a subset of 125 calves (every third calf as they entered the barn) to be fitted with 3-dimensional accelerometers (Hobo Pendant G data loggers; Onset Computer Corp., Bourne, MA) on 1 hind leg to continuously measure lying time, number of lying bouts, and lying bout duration. Calves were housed individually on slatted flooring (Tenderfoot; Tandem Products Inc., Minneapolis, MN) in 3 rooms of a mechanically ventilated barn. Health exams were conducted twice weekly for 2 wk starting the day after arrival. Exams included rectal temperature, navel score (0 = normal, 1 = mildly inflamed, 2 = moderately inflamed, 3 = severely inflamed), and fecal score (0 = normal, 1 = semiformed, 2 = loose, 3 = watery). Calves were considered to have navel inflammation (n = 22) or diarrhea (n = 15) if they scored ≥2 during at least 3 of the 4 health exams. The lying behavior of these calves was compared with that of normal calves (n = 18) that had no signs of illness and rectal temperatures <39.4°C during at least 3 of the 4 health exams. Data were analyzed using a repeated-measures ANOVA; models included cohort (1, 2, or 3), health status (normal, navel inflammation, or diarrhea), week (1 or 2), and a health by week interaction. There was an effect of health status on lying time, whereby normal calves spent more time lying compared with calves with inflamed navels and tended to spend more time lying compared with calves with diarrhea. There was no effect of health status on the number of lying bouts per day or on the duration of lying bouts. There were no health by week interactions. Results indicate that neonatal veal calves with navel inflammation and diarrhea may be less comfortable than calves without these conditions. Veal producers should consider adapting their facilities to create more comfortable lying environments to help calves better recover from disease, such as by adding a hospital pen with comfortable bedding.

许多小牛到达具有疾病的生长设施，包括腹泻和肚脐发炎。观察新生儿小腿行为，例如躺卧行为，可用于更好地检测和确定这些疾病的影响。这项研究的目的是确定肚脐发炎和腹泻对新生儿小牛躺卧行为的影响。这项研究是一项较大实验的一部分，该实验包括3个队列的360只雄性荷斯坦犊牛；从这些犊牛中，我们选择了125头犊牛（当它们进入谷仓时每第三只犊牛）的子集，以在1条后腿上安装3维加速度计（Hobo Pendant G数据记录仪；马萨诸塞州伯恩市的Onset Computer Corp.）。连续测量卧推时间，卧推次数和卧推时间。小牛分别饲养在板条地板上（嫩足；位于明尼苏达州明尼阿波利斯市的Tandem Products Inc.）位于机械通风的谷仓的3个房间中。从抵达后的第二天开始，每周两次进行健康检查，每周2周。检查内容包括直肠温度，肚脐评分（0 =正常，1 =轻度发炎，2 =中度发炎，3 =严重发炎）和粪便评分（0 =正常，1 =半成形，2 =松弛，3 =水状）。如果小牛在4次健康检查中至少有3次得分≥2，则被认为是肚脐发炎（n = 22）或腹泻（n = 15）。在4次健康检查中至少有3次将这些小牛的躺卧行为与没有疾病迹象且直肠温度<39.4°C的正常小牛（n = 18）进行了比较。使用重复测量方差分析分析数据。模型包括群组（1、2或3），健康状况（正常，肚脐发炎或腹泻），每周（1或2），以及每周互动的健康状况。健康状况对躺卧时间有影响，正常的犊牛与肚脐发炎的犊牛相比，躺卧的时间更多，与腹泻的犊牛相比，躺卧的时间倾向于更多。健康状况对每天卧床次数或卧床持续时间没有影响。每周互动都没有健康状况。结果表明，带有肚脐发炎和腹泻的新生小牛犊可能比没有这些情况的小犊牛更不舒服。小牛肉生产者应考虑改造其设施，以创造更舒适的卧姿环境，以帮助犊牛更好地从疾病中恢复过来，例如添加带有舒适寝具的围栏。因此，与肚脐发炎的犊牛相比，普通犊牛躺着的时间更多，而腹泻的犊牛则倾向于花更多的时间躺着。健康状况对每天卧床次数或卧床持续时间没有影响。每周互动都没有健康状况。结果表明，带有肚脐发炎和腹泻的新生小牛犊可能比没有这些情况的小犊牛更不舒服。小牛肉生产者应考虑改造其设施，以创造更舒适的卧姿环境，以帮助犊牛更好地从疾病中恢复过来，例如添加带有舒适寝具的围栏。因此，与肚脐发炎的犊牛相比，普通犊牛躺着的时间更多，而腹泻的犊牛则倾向于花更多的时间躺着。健康状况对每天卧床次数或卧床持续时间没有影响。每周互动都没有健康状况。结果表明，带有肚脐发炎和腹泻的新生小牛犊可能比没有这些情况的小犊牛更不舒服。小牛肉生产者应考虑改造其设施，以创造更舒适的卧姿环境，以帮助犊牛更好地从疾病中恢复过来，例如添加带有舒适寝具的围栏。健康状况对每天卧床次数或卧床持续时间没有影响。每周互动都没有健康状况。结果表明，带有肚脐发炎和腹泻的新生小牛犊可能比没有这些情况的小犊牛更不舒服。小牛肉生产者应考虑改造其设施，以创造更舒适的卧姿环境，以帮助犊牛更好地从疾病中恢复过来，例如添加带有舒适寝具的围栏。健康状况对每天卧床次数或卧床持续时间没有影响。每周互动都没有健康状况。结果表明，带有肚脐发炎和腹泻的新生小牛犊可能比没有这些情况的小犊牛更不舒服。小牛肉生产者应考虑改造其设施，以创造更舒适的卧姿环境，以帮助犊牛更好地从疾病中恢复过来，例如添加带有舒适寝具的围栏。
