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 (%) 226 604 4% of progeny were TB Reactors 36236 3% of herdmates were TB reactors Progeny had higher (worse) prevalance than herdmates
Sep 2025 Liver Fluke (%) 118 158 18% of progeny had damaged livers 1550 13% of herdmates had damaged livers Progeny had higher (worse) prevalance than herdmates
