Durabull® bulls are sires that produced trouble-free, fertile and long lasting cows.
ABS has met farmers' needs by creating the DURAbulls program to identifying proven dairy sires that meet the health and fitness standards demanded today.
The key building blocks of DURAbulls are:
- Calving Ability, Sire and Daughter - Stillbirth, Calving Ease
- Fitness and Management - Longevity, Daughter Fertility, Udder Health
- Functional Conformation - Udders, Feet and Legs, Body Condition
Actual daughter deviations for Longevity (PL) are required for DURAbulls eligibility.
The top 25% of the ABS sires for health and fitness traits carry the ABS DURAbulls logo.
