Scanning cows reveals an unexpected pregnancy

A cow had previously undergone 3 superovulation programs, with a yield of 60 embryos. The client was shocked by the fact that the cow was pregnant. The cow had been administered prostaglandin to induce oestrus after the superovulation program. 22 embryos were recovered after the superovulation program. Scanning revealed that the complete luteolysis did not take place, and 7 small corpal luteal were still present on the right ovary and none were present on the left ovary. This is the 1st incidence that I have witnessed incomplete luteolysis, following prostaglandin treatment.
