Experiment I
Twelve multiparous Holstein cows, aged 4 to 6
years, were selected from a brucellosis free herd. To
confirm that they are pestivirus antibody-free, all
cows were bled before commencing the experiment.
The cows were checked to determine their body
condition scores (based on 1 to 8), all animals were
in a range of 4 to 5 of condition score two weeks
before breeding. After a general examination, the cows were randomly divided into two control and
treatment groups, and placed in two paddocks. The
cows were being fed by good quality pasture grass
and supplemented based on the pasture condition.
