GLOSSARY

Condition score: An assessment of an animal’s condition based upon an estimate or measurement of the amount of fatty tissue under the skin on certain body parts.
Estimated Breeding Values (EBVs): These are predictions of an animal’s genetic merit, based on available performance data on the individual and its relatives.
Fertility: The ability of a bull to achieve, by natural service, a pregnancy rate of 60% and 90% in 50 normally cycling females, within 3 and 9 weeks of mating, respectively.
HD 50K and i50K: Commercially available DNA tests specifically designed for predicting performance and enhancing Estimated Breeding Values (EBVs) in black Angus cattle.
Serving assessment: Whether a bull can achieve a normal serve without problems being exposed under standard conditions (differing between temperate and tropical breeds).
Unsound bull: A bull that is not fit for breeding or a bull that has not passed a bull breeding soundness exam.
Veterinary bull breeding soundness examination: An exam developed to standardise bull fertility testing and evaluate whether a bull has met a set of standards for key fertility components indicating whether a bull has a high probability of being fertile.
Vibriosis: A sexually transmitted disease that causes infertility and abortions. It is commonly introduced to a clean herd by an infected bull(s).
