Embryo bull stats

[Nesikep]

hey, I was wondering a while ago, when you have all these embryo transplant bulls around, and they all have great statistics on weight gain, etc, how do you know how they would have done if they were on their biological mothers? Whats to prevent someone from putting an embryo from a cow with poor milk into a dairy cow for an adoptive mother and still getting great numbers from it?, the same can also be said, you can have a bull which doesn't look so good on paper because it was on a cow with less milk..

I'm not much of a fan of embryo transplants, AI is as far as I would go

First, the fact that they are an ET calf affects their accuracy as calves and it's taken into account when calculating their first EPDs. Second, as soon as their calf results come in their EPDs will be corrected.

and that would take how long? the bull has to be close to a year old, plus 9 month gestation, plus a year growing for the calf, another year until you get a calf from it

thanks for the clarification on how they do it, it just seems like a system that could be abused in my eyes

Probably no worse abused then reporting fudged birth, weaning and yearling weights or if he had to be pulled.

that's true, I'm sure so many things can be fudged, at some point you have to trust, or have solid proof.
