Breeding Worth
Breeding Worth (BW) is an index that ranks cows and bulls on their ability to breed profitable, efficient replacements. This page explains how BW is used to create herds resilient to changes and disease, therefore increasing farm profits.

Breeding Values
A breeding value is an estimate of an animal's genetic merit for a particular trait. Using breeding values to select cows and bulls to be the parents of the next generation is the most effective way to achieve genetic improvement.

Inbreeding
Inbreeding in cattle is when an animal's DNA is identical because it comes from a common ancestor on both parents' sides. This page explains how inbreeding coefficients estimate the expected degree of inbreeding, but these aren't always precise.
