Veal calves' clinical/health status in large groups fed with automatic feeding devices

Abstract

Aim of the current study was to evaluate the clinical/health status of veal calves in 3 farms that adopt large group housing and automatic feeding stations in Italy. Visits were scheduled in three phases of the rearing cycle (early, middle, and end). Results showed a high incidence of coughing, skin infection and bloated rumen particularly in the middle phase while cross-sucking signs were present at the early stage when calves' nibbling proclivity is still high. Throughout the rearing cycle, the frequency of bursitis increased reaching 53% of calves at the end. The percentage of calves with a poorer body condition than the mid-range of the batch raised gradually as well, likely due to the non-proportioned teat/calves ratio that increases competition for feed and reduces milk intake of the low ranking animals. The remarked growth differences among pen-mates and the mortality rate close to 7% showed by the use of automatic feeding devices for milk delivery seem not compensating the lower labour demand, therefore its sustainability at the present status is doubtful both for the veal calves' welfare and the farm incomes.
