Concentrations of agmatine and polyamines in uterine flushings. a Agmatine was less abundant than any of the polyamines in uterine flushings. b Concentrations of agmatine in uterine flushings were not affected by a day × treatment interaction. c Concentrations of spermidine in uterine flushings were unaffected by a day × treatment interaction. d Concentrations of spermine in uterine flushings were not affected by a day × treatment interaction. e Concentrations of putrescine in uterine flushings were not affected by a day × treatment interaction. f P4-treated ewes had lower concentrations of agmatine in uterine flushings than CO-treated ewes (P < 0.01). g P4-treated ewes tended to have lower concentrations of spermidine in uterine flushings than CO-treated ewes (P < 0.1). Only uterine flushings from ewes which were considered pregnant with normally developed conceptuses were utilized for these analyses
