Serum androgen levels in Duroc boars change significantly with age. Testosterone becomes the dominant androgen as the boar matures, correlating with testicular growth.

Area of Science:

  • Endocrinology
  • Animal Science
  • Reproductive Biology

Background:

  • Serum androgen concentrations are critical indicators of male reproductive development.
  • Understanding androgen profiles in swine is essential for livestock management and breeding programs.

Purpose of the Study:

  • To investigate the changes in circulating testosterone and androstenedione levels in Duroc boars from 5 to 27 weeks of age.
  • To determine the relationship between serum androgens, age, and testicular volume in developing boars.

Main Methods:

  • Jugular blood samples were collected bi-weekly from 11 Duroc boars aged 5 to 27 weeks.
  • Serum testosterone and androstenedione concentrations were quantified using radioimmunoassay.
  • Statistical analysis, including ANOVA and correlation, was employed to assess age-related changes and relationships.

Main Results:

  • Significant age-dependent variations in both testosterone and androstenedione levels were observed.
  • Testosterone levels initially decreased and then increased markedly by 27 weeks, while androstenedione peaked early and gradually rose later.
  • A significant positive correlation was found between testosterone and androstenedione (r=0.39) and between testosterone and testicular volume (r=0.48).

Conclusions:

  • Serum androgen profiles in Duroc boars exhibit distinct developmental patterns.
  • Androstenedione is the predominant androgen in early life, with testosterone becoming dominant as boars mature.
  • Testosterone concentration is closely linked to testicular development in growing boars.
