Prolactin and luteinizing hormone secretion after bromocryptine (CB-154) treatment in lactating sows and ovariectomized gilts.
Robert R. Kraeling,Robert R. Kraeling,G. B. Rampacek,G. B. Rampacek,Nancy M. Cox,Nancy M. Cox,Terry E. Kiser,Terry E. Kiser +7 more
TL;DR: It is concluded that CB-154 depressed PRL secretion in the lactating sows and OVX gilts, but the data are inconclusive as to whether or not BC-154 influenced LH secretion inThe OVx gilts.
Journal ArticleDOI
Serum luteinizing hormone and estrogen profiles before puberty in the gilt.
James B. Lutz,James B. Lutz,G. B. Rampacek,G. B. Rampacek,Robert R. Kraeling,Robert R. Kraeling,Carl A. Pinkert,Carl A. Pinkert +7 more
TL;DR: The hypothesis that an increase in serum luteinizing hormone (LH) concentration occurs before the onset of puberty in the gilt was tested and serum LH and estrogen concentrations were quantitated by radioimmunoassay.
Journal ArticleDOI
Metabolic changes during the transition from the fed to the acute feed-deprived state in prepuberal and mature gilts.
TL;DR: The metabolic response to acute feed deprivation in ovariectomized prepuberal and mature gilts is compared, with the transition from fed to unfed state occurs more rapidly in P than in M gilts.

TL;DR: Cortisol and luteinizing hormone (LH) were measured in serum after the administration of adrenocorticotropic hormone (ACTH) to suckled (S) and nonsuckled (NS) beef cows and the number of cows having LH after saline was found to be lower than in S cows at all sampling periods.
