Prostaglandin after ET

[Sostra]

My embryologist has been doing ET on horses in Western Europe for many years. I managed to convince him to try ET on cattle. So he has the following question.
After ET, do you have to give Prostaglandin to the recips from the time of ET to day 40?

NO!
You're thinking PROGESTERONE, not prostaglandin.
And, no, it should not be necessary for cows.

With Bovine recips you put the embryos in and then leave them - nothing else needed except decent nutrition.

As Lucky P said you probably mean Progesterone in your question. Prostaglandin is to make the females cycle and if you gave that post implantation you might cause the recip to abort the embryo and cycle again.

My question would be - If you are going to the effort to do ET work why not use someone who is familiar with Bovine work? I think most can probably flush embryos out, but my experience has been that when it comes to implanting and freezing there is a wide range of ability and attention to detail.

I think I would be finding an embryologist who was more familiar with cattle and didn't have to ask that question.
