摘要: The objective was to determine the effects of repeated injections PGF2alpha (Lutalyse; Pfizer) on semen and libido characteristics in terminal-line boars. Semen collected once weekly from wk 0 15 four consecutive days during 16. Boars received an i.m. injection 10 mg (n = 11) or 2 mL vehicle immediately before entering collection room. For collections, volume (220.3 +/- 3.2 mL; mean SE), gel weight (38.7 0.7 g), total sperm cells (65.4 1.2 billion), motile (67.4 0.6 %), velocity (125.9 microm/s), were affected by time (P 0.10). Sperm concentration (0.31 0.01 billion/mL) not > 0.10) treatment. percentage morphologically normal cells, assessed at 16, did differ 0.39) between groups (80.8 1.0).
