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.
|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|
