Effect of gastrointestinal nematode and liver fluke infections on weight gain and reproductive performance of beef heifers.
This is particularly the case for dairy heifers in the present study.
Teat and udder skin swabs were collected from imported heifers upon arrival at the farm, but prior to the heifers being co-mingled with resident cattle.
Additionally, foremilk samples were collected from cattle at parturition and skin swabs were taken from the udder of primiparous heifers.
One exception was a milk sample from a heifer at calving, which yielded two morphologically distinct colony types and two strains.
Approximately 20 weaned heifer calves were selected each year as replacements for dams culled from the herd.
Selection of immature heifer oocytes using the brilliant cresyl blue test (abstract).
