Sexual development of female prairie voles does not occur unless females are exposed to stimuli from an unfamiliar male. Three experiments were conducted to determine whether a saturable high-affinity estradiol binding site (ERN) is present in cell nuclei of brain tissue from females exposed to male stimuli and whether serum estradiol and brain ERN are(More)
In female prairie voles, behavioral estrus is induced by exposure to an unfamiliar male and ovulation is induced by mating. Experiments were conducted to determine whether a saturable high-affinity progestin binding site (PRC) is present in cytosols of brain tissue from females exposed to male stimuli for a period of time which is sufficient to bring most(More)
Japanese quail selected bidirectionally for adult mating frequency were utilized to study in vivo aromatization of testosterone (T) in relation to masculine copulatory behavior. Functionally castrated high (HM) and low mating (LM) line quail were injected with 75 microCi of [3H]T. One hour after the injection, all radioactivity recovered in(More)
Two hundred and six female breeder turkeys were fed on maize-soybean diets of equal energy content, containing 100, 120 or 140 g crude protein (CP)/kg to which DL-methionine was added at 0, 1, 2 or 3 g/kg diet in a factorial design. Serum albumin concentrations were found to be more sensitive measures of dietary protein adequacy than were total serum(More)
In female prairie voles ovarian estrogen secretion is stimulated by exposure to males. The present study determined that social stimuli can also enhance the neural response to estrogen. Ovariectomized female voles given a fixed amount of estradiol and exposed to males had higher levels of estrogen receptor binding in cell nuclei in the preoptic area than(More)
