Serum testosterone response in Holstein bulls after administration of luteinizing hormone.
Seven yearling Holstein bulls were given 0, 20, 40, 60, 80, 100 and 200 micrograms NIH-LH-B9 during a 7-day complete Latin square design experiment. Treatments were administered via jugular cannulas at 0900 hr, and blood was collected at 60, 30 and 0 min before treatment, at 15-min intervals for 3 hr after treatment and at 30-min intervals from 3 to 7 hr after treatment. Luteinizing hormone (LH...
متن کاملRelationship of growth hormone, prolactin and thyrotropin secretion to individual and progeny performance of Hereford bulls.
Six Hereford bulls from a line selected with an index of body weight and muscling score were compared with six bulls from a control line to determine if increased growth in the selected line was associated with changes in plasma levels of growth hormone (GH), prolactin (PRL) and (or) thyrotropin (TSH). The predictive value of sire hormone data for growth rate of progeny was also evaluated. Bull...
متن کاملGrowth-hormone and prolactin excess.
The treatment of acromegaly and hyperprolactinaemia has been improved by the availability of effective and well-tolerated slow-release somatostatin analogues and dopamine agonists with long-lasting activity, such as cabergoline. The use of these drugs has extended the possibility of treatment to patients who would have responded poorly to the previously available compounds, such as octreotide o...
متن کاملSerum prolactin and growth hormone response to thyrotropin releasing hormone in prepubertal heifers.
Prepubertal heifers were used to examine repeatabil i ty of prolactin (PRL) and growth hormone (GH) responses to thyrotropin releasing hormone (TRH) stimulation, and to determine effects of various doses and routes of administration of TRH on serum PRL and GH concentrations. Baseline concentrations of PRL and GH prior to intravenous (IV) injection of TRH in eight heifers were correlated (r = .6...
