IGS Contemporary Groupings Fact Sheet
The Importance of Correct Contemporary groups.
Every stud breeder should be familiar with this very simple equation: P = G + E.
Phenotype (P) is any measurable attribute or trait. Genotype (G) is the unique combination of genes each animal has and Environment (E) is any non-genetic factors that also influence the phenotype.
Different traits also have different heritability, meaning that the amount of the trait that is influenced by genetics varies from trait to trait. Importantly though, only the genotype can be passed on to an animals progeny, the environmental factors have no heritability at all.
To understand the effect of the genotype on an animal’s progeny, progeny are run under a similar environment within contemporary groups and their performance is measured. Given that the environmental component is similar for all animals in the contemporary group, the difference in the phenotypes (or variance), must be largely due to the effect of the genotype.
It is important that animals that have experienced different environmental factors, such as show cattle or sick or injured cattle, are grouped in their own contemporary groups, however breeders also need to ensure that they have strategies to maximise the size of their contemporary groupings.
So, here are 10 basic tips to help breeders maximise contemporary groupings:
Incorrect use of CG’s results in data bias. Ideally, the larger the CG, the more animals within your herd that are compared to each other. That is not to say that breeders should not use contemporary groups where needed, but the important thing is to structure your recording so as to limit contemporary groupings across each drop. The more you can do this, the better genetic evaluation will work for both you and your clients.
The Shorthorn breed is truly unique, from their distinctive roan colour, to their rich breed history and most importantly, the wonderful community of breeders, there is nothing else quite like a Shorthorn.
The key to the Shorthorn breeds advantage lies in their balanced genetic profile, driven by market participation that has been developed and refined, after more than 200 years of genetic selection under Australian conditions.
