It is a Jersey cross... someone mentioned Brown Swiss and I tend to lean that way as well... the hair is a bit too long and darker than a pure Jersey... the face is very Jersey
He's adorable! And I'm very close to you! We're practically neighbors!
You should be able to feel for little horn buds to know if he's polled, I 'think' most jerseys are horned. One thing to keep in mind about the horns, most those farmers that don't, also don't raise them up as pets. You can get the horns tipped, which helps. My cow is horned and can easily hurt you by turning her head to quickly when you are near (she was a bottle baby, so 'pet' raised), but it hasn't been as bad since they were tipped, if I had it to do over again I'd have disbudded her.
He's adorable, I feed my bottle calf 3 times aday, but started out w/ 4 times a day, baby calves act like they are always hunger, but be careful not to over feed.
