About 1/3 of the productivity improvements farmers have achieved in the last decade have come from better genetics – and most of this from using superior bulls. ADHIS has a number of tools that farmers can use to identify bulls suited to their breeding objectives.
Good Bulls Guide
The Good Bulls Guide is a simple way to choose bulls backed by strong, independent science. Bulls listed have been identified by ADHIS's independent, scientific assessment using the world’s best practice genetic evaluation. The guide helps you compare apples with apples regardless of the company or country from which the bull is sourced.
Using the Good Bulls Guide is simple:
Step 1: Choose your index:
To support farmers in breeding a more profitable herd ADHIS presents three breeding indices which reflect the breeding philosophies of Australian farmers.
Download your copy of the Choose your index support tool and then use the Good Bulls Guide to choose bulls on your index.
Step 2: Go to the table that matches your chosen breeding priority and pick bulls with confidence.
Genetic information for tens of thousands of bulls is available in Displayabull – the ADHIS database. ABVs for well proven AI bulls, newly released proven bulls, young genomic bulls and even recorded natural bulls can be found in one place.
Displayabull is handy for:
- comparing bulls in your short list for a full range of traits
- checking a bull’s unique name so your stock register is accurately maintained
- discovering sire and maternal grandsire information
- checking for genetic recessive genes like red coat colour in Holsteins
Semen Fertility Values
While conception rates are similar for semen from most bulls, some bulls have higher or lower conception rates. Farmers and herd improvement service providers can compare bulls based on the fertility of their semen.
Using hundreds of thousands of mating records collected through data centres around Australia, ADHIS produces a Semen Fertility Values for bulls with more than 400 matings. Semen fertility values relate to the ability of the bull’s semen to get cows in calf. The results are released with ABV releases and published on the ADHIS website.
