    Summary

    Canine semen analysis reveals sodium and aminotransferase levels may indicate sperm health. Acid phosphatase in seminal plasma could serve as a useful indicator of prostate function in dogs.

    Area of Science:

    • Veterinary Science
    • Reproductive Biology
    • Biochemistry

    Background:

    • Assessing canine semen quality is crucial for breeding programs and reproductive health evaluations.
    • Understanding the biochemical composition of seminal plasma and sperm fractions can provide insights into male reproductive function.

    Purpose of the Study:

    • To determine the concentrations of key biochemical components in seminal plasma and sperm fractions of beagles.
    • To investigate the relationship between these components and semen quality parameters like sperm motility.
    • To evaluate the potential of specific biochemical markers for assessing sperm damage and prostate function.

    Main Methods:

    • Weekly semen collection from eight mature beagles over six weeks.
    • Separation of seminal plasma and sperm fractions via centrifugation.
    • Biochemical analysis of sodium, potassium, alanine aminotransferase, aspartate aminotransferase, acid phosphatase, and alkaline phosphatase concentrations.

    Main Results:

    • Sodium ion concentration was highest in seminal plasma.
    • Aminotransferase levels were highest in sperm fractions, potentially indicating damaged spermatozoa.
    • Acid and alkaline phosphatase activity was significantly greater in seminal plasma compared to sperm fractions.
    • Sperm motility showed independence from seminal plasma potassium but suggested a correlation with seminal plasma enzyme and sodium content.

    Conclusions:

    • Seminal plasma acid phosphatase may serve as a valuable index for canine prostate function.
    • Biochemical markers like sodium and aminotransferases in different semen fractions could be useful indicators of sperm health and integrity in dogs.
