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

PTAs are interpretative of the expected prevalence of TB or Liver Fluke infection in that animal's progeny.
Therefore, lower PTAs are more desirable.

Progeny and Herdmate Performance

Date of Evaluation Trait Total Herds Total Progeny Records Average Progeny Prevalence Total Herdmate Records Average Herdmate Prevalence Interpretation
Sep 2025 TB (%) 443 1170 3% of progeny were TB Reactors 74246 3% of herdmates were TB reactors Progeny had same prevalance as herdmates
Sep 2025 Liver Fluke (%) 430 595 15% of progeny had damaged livers 4823 13% of herdmates had damaged livers Progeny had higher (worse) prevalance than herdmates
