Jd. Quigley et al., EFFECTS OF HOUSING AND COLOSTRUM FEEDING ON SERUM IMMUNOGLOBULINS, GROWTH, AND FECAL SCORES OF JERSEY CALVES, Journal of dairy science, 78(4), 1995, pp. 893-901
Ninety-six Jersey calves were used to evaluate the effects of housing
and method of colostrum feeding on serum Ig concentrations, incidence
and severity of scours, intake, and BW changes from birth to 35 d of a
ge. Calves were separated from the dam and fed 2 L of colostrum in nip
ple-bottles or allowed to nurse the dam for 3 d. Calves were housed in
individual hutches or wooden pens in a barn. Intake of colostrum by c
alves allowed to nurse the dam was not controlled. Serum IgG and IgM c
oncentrations at 24 h of age were greater for calves that nursed the d
am. Scours were less severe when calves were housed in hutches, but nu
mber of days scouring was unaffected by treatment. Calves fed colostru
m in nipple-bottles and housed in the barn consumed more starter than
did other calves from 3 to 5 wk of age. The BW were greater for calves
allowed to nurse the dam and housed in hutches. Feed efficiency over
the 35-d study was improved when calves nursed the dam. Optimal transf
er of passive immunity and housing in hutches appeared to maximize hea
lth and growth in this study.
