Pedigree still remains a primary tool in evaluating a Wagyu bulls genetic potential with Japanese breeders using 16/16 analysis of the pedigree as an indication of how a bull may potentially perform under progeny testing. This must correlate with the phonetical characters associated with the pedigree indicating the likelihood of the bulls ability to express its gene’s in a first cross, taking into account the phenomena of heterosis, especially with F1 breeding programmes.
Progeny Test –
Due to the relatively small Wagyu population as well as the variating results caused by gene expression in feeding techniques, EBV’s and Gene marker technology still remain a secondary tool in evaluating marbling performance with Wagyu sires. To accurately and or more reliably assess the genetic potential of the sire in question the progeny test should be carried out in conditions associated with production style. Due to these factors, well-established Wagyu breeding programmes in Japan still use the progeny test as a primary tool in genetic selection.
Sustainable Breed development –
As Wagyu Genetic’s Europe progress, our goal is breed development through progeny testing, pedigree analysis and careful attention to recessive genetic disease utilising methods of line breeding combined with rotational breeding techniques in maximising heterosis internally within the Wagyu breed insuring optimum hybrid vigour is achieve whilst maintaining high marbling performance
Epigenomics – The practice of feeding our breeding stock to optimise SCD (marbling gene expression ) is a new but well-established phenomena with experienced breeders. Using careful timing of the implementation of certain supplements we can positively alter gene expression which is then inherited in the heifer of sires progeny.
