Summary
We developed an efficient 10-plex PCR test for pig parentage control using microsatellite markers. This method offers automated, cost-effective, and time-saving genotype analysis for improved pig breeding programs.
Area of Science:
- Animal Genetics
- Molecular Biology
- Livestock Breeding
Background:
- Accurate parentage control is crucial for livestock breeding programs.
- Traditional methods for pig parentage testing can be time-consuming and costly.
- Microsatellite markers offer high polymorphism for genetic analysis.
Purpose of the Study:
- To develop an efficient and cost-effective parentage control system for pigs.
- To establish a multiplex PCR assay for rapid genotype analysis.
- To determine the combined exclusion probabilities (CEPs) for important Austrian pig breeds.
Main Methods:
- Utilized ten polymorphic microsatellite markers.
- Developed a single 10-plex PCR reaction for simultaneous analysis.
- Calculated combined exclusion probabilities (CEPs) for paternity and parentage control scenarios.
- Designed an additional 5-marker battery for enhanced accuracy if needed.
Main Results:
- Achieved high combined exclusion probabilities (CEPs) for Landrace, Piétrain, and Large White breeds.
- CEPs reached up to 99.76% for paternity control and 99.99% for parentage control.
- Demonstrated the feasibility of automated, cost- and time-reduced genotype analysis.
- An additional 5-marker panel was developed for cases requiring higher CEPs.
Conclusions:
- The developed 10-plex PCR assay provides an efficient tool for pig parentage control.
- This method significantly reduces costs and time associated with genetic analysis in pig breeding.
- The system offers high accuracy and flexibility with an optional supplementary marker set.
