Prenatal @entity342 exposure and growth and secretion of XXXX and @entity31008 in ewes postweaning.

@entity742 @entity12550 @entity31008 @entity342 @entity11335
Growth and secretion of @entity12550 ( @entity12550 ) and @entity31008 (PRL) in ewe @entity742 exposed to @entity342 during fetal development were investigated. @entity11335 was administered to the pregnant dams from approximately Days 28 to 84 of gestation. Ewe @entity742 from dams that received @entity342 exhibited masculinized external genitalia and some masculine behavioral characteristics. Intact androgenized ewe @entity742 grew faster (P less than 0.05) and were more efficient in conversion of food to body gain (P less than 0.05) than ewe @entity742 born to untreated dams over the period from 70 to 224 days of age. One-half of the ewe @entity742 in each group was ovariectomized at 58 days of age. Ovariectomy had no effect on subsequent growth or efficiency of growth in the control ewe @entity742 . However, ovariectomy of androgenized ewe @entity742 abolished the observed stimulated rate of growth and decreased the improvement in efficiency of food conversion. Blood samples were collected from the @entity742 at 85 and 136 days of age at 15-min intervals for 8 hr to determine parameters of @entity12550 and PRL secretion. Prenatal @entity342 exposure had no effect on any parameter of @entity12550 or PRL secretion. These data indicate that prenatal @entity342 exposure altered differentiation of growth potential in ewe @entity742 , but the growth response was not mediated through dramatic changes in secretion of adenohypophysial somatotropic hormones, @entity12550 and PRL.
