Raising the right size cattle

for better feed efficiency and profitability


Frame score.

Hip height converted to frame score is a linear measurement that helps cattle producers evaluate lean-fat ratio potential of an individual animal in a performance program. No one frame size will be best for all feed resources, breeding systems, and markets. Large-framed animals tend to be heavier at all weights, leaner, and later maturing. Small framed animals tend to be lighter, fatter, and earlier maturing.

Frame scores can be monitored to maintain body size, fatness level, and maturing rate within the optimum ranges dictated by the resources, breeding system, and market specifications of a herd.

Frame score is a convenient way of describing the skeletal size of cattle. With  appropriate height/growth curves, most animals should maintain the same frame score throughout their life, regardless of when they are evaluated. However, frame scores may change for animals that mature earlier or later than average

for their breed.

There are different frame score charts in the industry having different height categories. The Miniature Herefords have an official chart that covers categories between 0000 and 1. American Hereford Association has their official chart that covers categories between 4 and 9. There are other charts but most of them use the same formulas for their calculations.

Between the two different Frame Score charts, there is a hole that does not have a description of those Frame Score categories.  Below is the chart we will use to describe “Classic Size” cattle. This will be used for our Herefords
