Kinda reminds me of those calves my 'Angus' bull provided me with the spring before last.
It's hard to tell from the photo if there's any beef breeding at all in its make-up. The red colour would be unusual in a (black) HolsteincrossJersey but perfectly normal from Jersey over crossbred or crossbred over crossbred.
In either case, more than 50% Jersey. Second breed Angus or Holstein.
