Abstract
Objective of the present study was to compare the responses of Holstein Friesian
pre-weaned female calves confined in elevated metallic crates in closed-type of
housing and polyvinyl hutches in an open environment of
Kuwait.
A total of 176 newborn Holstein Friesian female calves were randomly distributed
to conventional confinement in closed-type calf houses (control) and individual
calf hutch in open environment (treatment). These calves were monitored upto the
weaning age of 90 days. The average daily live weight gain was significantly
higher in calves housed in hutches than conventional housing system (413 versus
113 g/h/d; P≤0.0001). Mean risk rates (RR) for mortality in hutch and
conventional housing were 0.017 and 0.23, respectively. The results showed a
significant positive impact of hutch housing with respect to growth, mortality
and incidence of diseases in
Kuwait’s
intensive dairy farming system.
