Mark, just read last night that ABS is/has developed an EPD for shear test. Brent
hmm, that will be misleading, as the alleles are supposedly additive, so it will be interesting to see intervals less than 0.7 lbs.
imagine you have an animal like ali who is het for all three. wonder what his epd will be? using an epd, it would be better if the animal was homo for the alleles, again to guarantee transference of allele.
since T2 is the rarest, no epd is going to help you get it.
i guess i'll look at the ABS site.
i did notice THIS before

it would be so easy to study why. ugh.
so the best bull, FORESIGHT, is 0.5kg less shear force than say a 2.2 animal. math .5/2.2= 22% improvement. perhaps he has genes which are not additive and bovigen didn't include. wonder what foresight would be with the other allele of T2. any bets on additive, antagonistic, no change? there's some insight available with 234d not having T2 at all and look at his numbers compared to foresight.
man, i need some money.
personally, if i was going to redo the amaa, i know what i'd do.
forgot to say, the ABS thing depends on the cow base and what was transferred to animals under "test".
here's where i would like some more detail.
i want to know what the killed animals had, in addition to the bull.
it's easy to be confused by a cow base with a higher allele count. this is obvious looking at foresight versus alliance. 30 animals is only 5 over what is typically used for a "population" in statistics and is bogus since the cowbase is unknown, as is the animals slaughtered.
i put NO faith in this EPD.
