Recip Cow Question

[OH HSC]

We are going to flush a couple of cows and put thier eggs into some of our other cows. The donors in this case consistently have large calves from the matings we are going to use. (100-130) These cows have very little trouble with this size of calf. However, I am worried about the size of some of our recips. My question is, will the donor or the recip determine the size of the ET calf? These recips rarely have calves over 100. What is your opinion on this?

The flush mating will determine the size of the calf.  The recip can add or take away pounds by environmental causes like lack of nutrition or overfeeding.
