title: Seminal plasma composition in budgerigars (Melopsittacus undulatus).
abstract: Seminal plasma composition was studied in budgerigars. Semen was obtained from adult male budgerigars by applying gentle pressure to both sides of the cloaca. Pooled samples were centrifuged at 15,000 g for 2 min, and the seminal plasma separated for biochemical analysis. Osmolality, Na+, K+, Cl-, pH, glucose and fructose values were determined. The biochemical composition of budgerigar seminal plasma obtained in this study was: Osmolality 329.9 +/- 14.5 mOs/kg; Na+ 158.6 +/- 8.4 mEq/l; K+ 16.39 +/- 6.24 mEq/l; Cl- 109.2 +/- 7.4 mEq/l; pH 8.20 +/- 0.18 glucose 4.25 +/- 0.96 mmol/l; fructose 0.59 +/- 0.29 mmol/l. The results are discussed in relation to the values reported for the domestic fowl. This forms part of a reproductive biology study of non-domesticated avian species.
