Utilisation of a sperm quality analyser to evaluate sperm quantity and quality of turkey breeders

British Poultry Science, 2002
1. A relatively new instrument known as a Sperm Quality Analyzer (SQA) offers a rapid assessment of sperm quality and quantity by providing a sperm quality index (SQI). The SQA measures a combination of the intensity of sperm activity and motile concentration by determining the number and amplitude of sperm movements per second in a capillary tube as ...

Use of the Sperm Quality Analyzer (SQA II‐C) for the Assessment of Dog Sperm Quality

Reproduction in Domestic Animals, 2002
ContentsIn the present study, an automated system for sperm analysis, the Sperm Quality Analyzer (SQA II‐C), was tested as a potential tool for the assessment of dog sperm quality. In the first experiment the device displayed a good repeatability of measurements for semen of medium and high quality, as evidenced by a low coefficient of variance (CV; 0 ...
