with a corpus luteum (CL) present on the right ovary.

She was bred via artificial insemination on day 82 post-partum. Which one of the following would be a cardinal sign of the suspected pregnancy at this examination?
corpus luteum
ballotment of the fetus
identification of fetal membrane slip

Answer 1

PG to identification of fetal membrane slip. RScott

Answer 2

Going to a dairy farm and hearing the farmer shout to his herd, "OK girls time to shed your load" and watching the cows head towards the milking shed at a rapid pace I would say not. Most girls like their udders fondled and twice a day I reckon they would be up for it.
