Polymelia in Angus cattle

http://hereford.org/node/343 This is the article.  Starts on page 24 I think. It is a little light on hard and firm data.
I am not saying that I have the answer for what the Angus Association should do, but I do hope that they are very careful in their decision making. Strict, clear guidelines are needed, one way or the other.

Someone on CT posted a link as well.

Distilled down, there is a gene that confers resistance to Salmonella.  If you are heterozygous, you have less than if homozygous.  All cattle can have this gene.  What they have discovered that a gene that controls pigmentation black vs. red appears to complement the resistance gene, so red cattle have an enhanced effect.  They also state that they believe that there may be other genes that could complement the resistance gene in black cattle.  But they haven't found it yet.

I agree that there is a lot more to be done on the subject. Interesting though.

i knew it, black is a defect.

Brazil is not only Nelore.
I raise Shorthorn, Aberdeen, Hereford and Galloways.
I'm talking about Angus and Hereford from US and Canada bull listed on semen catalogues.
Last year Red Angus sold 541.000 straws; Angus sold 2.338.097; Polled Hereford sold 122.104 straws and Hereford sold 5.963 straws.
Nelore sold 3.320.598 straws. The other indian breeds sold together 287.461 straws....
So genetic defects are also an important matter here in Brazil.

I apologize for making that assumption. If the bloodlines are the same, the abnormalities need to be tracked.

No problem. I undrstand that people believe that Brazil is a zebu country, but we are not!
These genetics defects is an important matter as almost 80% genetics came from US and Canada. Here people show not same knowledge that North American breeders.
