He sure looks stout, with plenty of thickness and adequate depth.
However, I must admit that I've been a little fooled by some long haired cattle (i.e. Highlands and Galloways). Some of them appear more muscular than they really are because the hair gives them the appearance of having more muscle than what they really do.
Are you going to have him breed the crossbred cow (HerefordXShorthorn ?) that was in the earlier email? If so, it will be interesting to see what the calf looks like.
