Breeding for resistance to TB and Liver Fluke can help protect your herd from TB and Liver Fluke infection.


Each animal's breeding value is expressed as the predicted prevalence of TB or Liver Fluke for that animal's progeny.
Therefore, a lower PTA value is more desirable

Progeny and Herdmate Performance

Date of Evaluation Trait Total Progeny Records Average Progeny Prevalence Total Herdmate Records Average Herdmate Prevalence Interpretation
Jan 2020 TB (%) 89 3% of progeny were TB Reactors 5181 3% of herdmates were TB reactors Progeny had same prevalance as herdmates
Jan 2020 Liver Fluke (%) 47 19% of progeny had damaged livers 463 18% of herdmates had damaged livers Progeny had higher (worse) prevalance than herdmates
