I need a review on what I have learned about black cattle. Recently I had a discussion with a co-worker on the farm where I work and they were telling me how there vet raises Gelbvieh. I asked red or black, they replied black. Now I thought that breeds that were originally red such as, Gelbvieh, and Limousin turned black because Angus was thrown in there for color, then bred out of them. This co-worker told me that the blacks came about much like how red angus did with red or diluted gene. Only these had a black gene. This animals were then bred to each other and bam you got another color animal. So someone pleas review me...lol DOC HARRIS??? Dun??? Anyone?
