to assess the potential relationship between prostaglandin release from the ovarian follicles and emg activity in egg-laying hens , we determined the concentrations of pgf2 alpha , 13,14-dihydro-15-keto-pgf2 alpha ( pgfm ) , and pge2 in brachial , ovarian follicular and uterine venous plasma and tissues in relation to uterine muscle emg activity at the first ovulation and at a midsequence oviposition .
