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
May 2023	TB (%)	318	915	6% of progeny were TB Reactors	35515	5% of herdmates were TB reactors	Progeny had higher (worse) prevalance than herdmates
Mar 2023	TB (%)	317	914	6% of progeny were TB Reactors	35336	5% of herdmates were TB reactors	Progeny had higher (worse) prevalance than herdmates
May 2023	Liver Fluke (%)	194	210	30% of progeny had damaged livers	1114	30% of herdmates had damaged livers	Progeny had same prevalance as herdmates
Mar 2023	Liver Fluke (%)	190	206	30% of progeny had damaged livers	1103	31% of herdmates had damaged livers	Progeny had lower (better) prevalance than herdmates
