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 (%)	645	1537	4% of progeny were TB Reactors	78247	4% of herdmates were TB reactors	Progeny had same prevalance as herdmates
Mar 2023	TB (%)	636	1523	4% of progeny were TB Reactors	76344	4% of herdmates were TB reactors	Progeny had same prevalance as herdmates
May 2023	Liver Fluke (%)	640	749	23% of progeny had damaged livers	4329	22% of herdmates had damaged livers	Progeny had higher (worse) prevalance than herdmates
Mar 2023	Liver Fluke (%)	628	737	23% of progeny had damaged livers	4246	22% of herdmates had damaged livers	Progeny had higher (worse) prevalance than herdmates
