Quality Assurance01:19

Quality Assurance

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...
Quality Control01:05

Quality Control

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Area of Science:

  • Veterinary Science
  • Animal Reproduction
  • Andrology

Background:

  • External quality control programs are established in human andrology to improve semen assessment accuracy.
  • Boar semen assessment in artificial insemination (AI) stations presents complex demands for identifying poor ejaculate quality and monitoring storage differences.
  • Semen assessment is crucial for controlling the security and efficiency of semen processing.

Purpose of the Study:

  • To evaluate the effectiveness of external quality control for boar semen assessment in AI stations.
  • To compare flow cytometry with light microscopy for detecting sperm damage in stored boar semen.
  • To identify influences of semen processing on sperm quality and explore potential for fertility estimation.

Main Methods:

  • Centralized studies involving stored semen from 11 AI stations.
  • Flow cytometric assessment of plasma and acrosome membrane integrity.
  • Comparison of flow cytometry results with light microscopy for detecting sperm damage.

Main Results:

  • Flow cytometry was more sensitive than light microscopy in detecting sperm damage from ageing and temperature stress.
  • Significant differences in membrane integrity were observed between AI stations, indicating processing influences.
  • Sperm quality varied, suggesting a need for monitoring individual boar responses to storage.

Conclusions:

  • External quality control can monitor AI station internal controls, identify males with poor semen quality or storage response, and verify sperm counting precision.
  • Flow cytometry offers a more sensitive method for assessing boar sperm viability and damage.
  • Centralized assessment could potentially identify sperm subpopulations for improved fertility estimation.
