Do rat tail cows have rat tail calves?

Rat tail is the effect of the diluter gene for color, the hair is different then normal also. Feedlots discount them. I was alwasy told it's because rat tails don;t do well in feed lots. But it may just be that they can discount them so they do.

Good article, but basically, all it proves, is that cattle with very little hair don't gain as well as haired cattle in cold weather. BW & WW were normal. I'm sorry to admit, but I don't know KG to LBs. Can someone give the difference in pounds? Not that it makes any difference - they gained less during the winter months - that's a given. And, I have never heard of an animal referred to as a rat tail other than greys, also.jnowack":18t0d8f7 said:The rat tails don't do well in the cold. It is caused by interaction of different gene pairs. This article says that they must carry at least one black gene and be heterozygous at the other locus (I assume this is the locus where the rat tailed gene is located). This article does not talk about the diluter gene, but I was told that they had to carry a diluter gene also which would be a third locus. I have never heard of a rat tail that was not grey.

a rat tail will have a small amount of striat hair's were the switch would be. and kinda taper out to a pointed end . one that lost it too damage like that would have a blunt look too ithillsdown":3epl63sm said:Yesterday when walking through the calves I noticed one had no switch at the end of the tail.I pointed it out to my husband and he said she must have lost it or froze it.But now you have got me thinking that it might be a rat tail.I never noticed it before but perhaps that's what it is.After checking out the links on this post makes me think it possibly is.She is at Gelbstein (our vet calls her the new kosher Jewish breed).The dam is a holstein that we flushed and couldn't get her rebred to AI holstein semen so I put her in with my GV bull.Maybe the combination of the two breeds is what caused that.She is a beutiful heifer solid chocolate brown and huge a good 75lbs heavier than the other calves in her group but then she does get alot of milk.

Frankie, I don't have the article and my old brain would NEVER remember where I read it. Shouldn't have said PROVED. I read a university article saying it was not true. I have had some awesome rat tail's in years past.
