Abstract:
A total of 133 observations on mean daily mass gains from 19 calves reared on either whole milk (control)
or preserved colostrum (treatment) were estimated. The control group had a total of 104 observations
computed, while the treatment group had a total of 29 observations. There was no significant difference
in the overall mean daily mass gains between the treatment and control groups which were
0,2257 and 0,3607 kg, respectively (P < 0,1 ). Partial budgeting analysis estimated that with an annual
calf crop of 80 calves, the use of preserved colostrum would result in a direct saving of an estimated
US$1 ,800 per year for the farm.
