Breeding for resistance to TB and Liver Fluke can help protect your herd from TB and Liver Fluke infection.
Each animal's breeding value is expressed as the predicted prevalence of TB or Liver Fluke for that animal's progeny.
Therefore, a lower PTA value is more desirable
|Date of Evaluation||Trait||Total Progeny Records||Average Progeny Prevalence||Total Herdmate Records||Average Herdmate Prevalence||Interpretation|
|Jan 2020||TB (%)||4||25% of progeny were TB Reactors||251||2% of herdmates were TB reactors||Progeny had higher (worse) prevalance than herdmates|
|Nov 2019||TB (%)||1||0% of progeny were TB Reactors||105||4% of herdmates were TB reactors||Progeny had lower (better) prevalance than herdmates|
|Jan 2020||Liver Fluke (%)||1||100% of progeny had damaged livers||4||0% of herdmates had damaged livers||Progeny had higher (worse) prevalance than herdmates|
|Nov 2019||Liver Fluke (%)||0% of progeny had damaged livers||0% of herdmates had damaged livers||Neither Progeny nor Herdmate records were used to estimate breeding values for this animal|
