Each extra inch of girth gives an extra 37 pounds of red meat. A well-balanced animal will be a third neck a third back and a third rump. A bull with early hormone development should have a neck with a large hump and a neck that is at least two inches short one third at twelve months. Shorter is better. The larger the hump at twelve months of age which makes the neck shorter, the more mail hormones present.
Short necks are a good indicator for libido.
As the neck gets shorter his daughters' rump width gets wider producing more pounds of beef. Rump height indicates ability for ease of self-fleshing and ease of keeping as well as early maturity. Provides space for larger loin and eye. A bull's shoulders should be a minimum of two inches wider than his rump length. Wider is better.
