Veal calves are at high risk for disease and mortality in early life. Calves face several stressors before arriving to the grower, including long transport times, which may contribute to poor health. Our objectives were to (1) estimate the prevalence of poor health outcomes in veal calves on arrival to growers in Ohio, (2) determine risk factors for health outcomes on arrival, including auction site (spread across 5 states in the Northeastern US), and (3) determine if health outcomes on arrival predict early mortality. A physical examination was conducted on approximately 30 calves from 12 cohorts (n = 383 calves). Exams included a blood sample to determine packed cell volume (an estimate of dehydration using a cut-off >46%) and total protein (an estimate failure of passive transfer using a cut-off <5.5 g/dL). Diarrhea, respiratory disease, depression, navel inflammation, and a skin tent test (a second indicator of dehydration) were also recorded. Mortality within 4 wk of age was recorded from farm records. Descriptive statistics were used to describe the prevalence of calves with poor health outcomes upon arrival. Generalized linear mixed models were used to identify risk factors for poor health on arrival and assess if poor health increased the incidence risk of mortality. Upon arrival, 6% (95% CI: 4.4–7.6) of calves had failure of passive transfer, 14% (9.1–18.8) presented with diarrhea, 0.5% (0–1.3%) had respiratory disease, 14% (8.5–19.3) were depressed, and 27% (22.7–30.7) had inflamed navels. In addition, 35.1% (23.5–46.6) of calves were dehydrated using a skin tent test, but only 1.3% (0.0–2.9) were dehydrated based on the packed cell volume threshold. Auction site of origin was significantly associated with depression on arrival (P < 0.001), and tended to be associated with skin tent on arrival (P = 0.08). None of the health variables were predictors of early mortality; however, morality was generally low for all cohorts (4.3%; 1.7–6.8). These results provide evidence that veal calves experience dehydration, diarrhea, navel inflammation, and depression on arrival to growers, and some health outcomes are dependent on auction site.
