most important thing to remember when obtaining a urine sample
from a cow is to only touch the cow with the hand that you will
use to stroke the vulva or perineum. This means no one
else should be touching the cow. Note that if no urine is
obtained after 3 - 5 minutes of stimulation, then stop and move
on to the next procedure.
The urine will be used to measure
ketone bodies. (See
Insert a well lubricated
thermometer into the rectum of the cow. A large animal
thermometer is required for this procedure. This will
allow for complete insertion through the anal sphincter and into
the rectum. Rectal temperatures vary according to
season. Temperatures range from 101.5° to 103.5°F.
The pulse can be obtained from the
coccygeal vein by placing index finger on the ventral midline aspect of the
tail at the level of the vulva. It is normally faint and intense
concentration is needed to feel this pulse. The normal pulse is
60 - 80 bpm.
The vulvar mucous membranes
should be moist, shiny, smooth, and pale pink. To
assess the mucous membranes, gentle separation of the vulvar
lips using both hands is preferred.
