This one. Seriously. There are alot of folks out there who know a great deal. I know just enough to know that I don't know enough, LOL. There is a great deal of info right here if you take the time to read through it all. You'll also note that we are all opinionated and never totally agree about everything.
Cows have their own personalities just like people. Each one is different, yet they are all the same in some way. There are die hards from each breed over in the breeds forum and there are folks like me who just raise plain old cows. A good cow is just that, no matter what breed she belongs to or is crossed out of. If she does her job with what I am willing to give her, she's a keeper.
To answer the question over in the other board, that calf should fetch about $200 now. If she works out, turns out to be a good looker, you could sell her, as a cow calf pair, in about 20 months, for anywhere between $800 to $1350, at current prices at auction in my proximity. I don't know what your local auction barns pay. If you go that route, you should get her vaccinated for brucelosis etc. Your vet can help you with that.
Just when you think you've heard it all, a new trick shows itself. Sometimes I don't have time for the bunk I read here and other times I find myself completely fascinated.
You can google subjects like, "bottle calves." You'll get someone's opinion there too. People just like you and I write books. Some know what they are talking about and some don't. If you read enough, experience enough, eventually you will be able to debunk things yourself. When i don't know, I try to get a deversified opinion & weigh the pro's N cons. You'll also have to bear in mind that folks here are just plain good ole folks, bless their hearts. You'll see things in my writing such as the words, "there", "their" and "they're" all out of text. I don't have to pay an editor to keep me straight.
