I've known a few people who had them (and seemed to like them), but we've never had them here; they're not climate-appropriate for us. Personally, I prefer cattle without horns at all, LOL.
The cattle we have are the descendants of DH's grandfathers' herd; they've been on grass only for nearly forty years, so the selection was mostly done for us. We just had to cull out the bad actors and concentrate on the lines that produced great beef . Because most farmers sell to a stockyard, they never know what they're producing in terms of quality - we know, so we can select for it. We operate a completely closed system (no cows or calves are brought to the farm), so it's not likely I'll ever meet a longhorn, and our equipment wouldn't work for them. Sorry I can't be of more help .
**editing to add - if you want to play with cattle, start by searching out books on cow psychology & handling. Read Temple Grandin's stuff, especially. They're BIG, and unlike birds, they can kill you; learn how to control and get along with them before you bring one home!
