No, you wouldn't get any rat tails, they should all come out tan. But depending on the bull you use, you would possibly get roans or spots. Might not be a problem, but if you're selling commercial cattle, spots and roans might cost you something.
Rat-tailed calves are usually mouse grey, have short, curly and sometimes sparse hair and lack normal tail switch development . They are often seen when crossing Charolais with Angus (or other black cattle). Can also happen when using Simmental and very rarely Hereford crossed with Angus.

A. Homo black would give you various shades of grey. Anywhere from almost white to almost black.
B. Hetero black would give you various shades of grey AND various shades of tan.
C. Gelbveih would depend on what color. Homo black, same as...
Believe it or not, we don't. Every calf makes the trip through the barn. Most just get a quick trip into the barn on their way by. We have a pasture we calve in and once the cows have dropped their calves we move them to the newborn pasture for about a week or 10 days (both pastures/pens are...
Well, we started out using a bathroom scale. Then went to an old beam scale with a crate on it. Now, we have a single animal digital scale so we just put it in the barn at calving, set a piece of plywood on it and use it. Just toss the calf on it and it takes about 30 seconds.
I have absolutely NO tolerance for cows like this. Whether she attacks you when you catch her or not. She runs from the very sight of people. One wild cow will and DOES stir the entire herd up. You have to watch your back around her, and even walking through the herd when you pen them is taking...
Just remember that whenever you cross one breed with another your get hybrid vigor. This is why crossbred calves weigh more at weaning (in general) than purebred calves. It affects everything from growth to longevity. As far as hybrid vigor, it doesn't start at birth, this can make heavier BW's...
I use a lot of my own spreadsheets and tables too. I love the program I have, but there are some things it just doesn't do for me. But as as far as looking up an individual animal and anything to do with her in a second, Ranch Manager works great.
Most of my spreadsheets are things I can...
