摘要: Abstract Two short term studies of LH and testosterone secretory profiles were carried out to evaluate the effects stage sexual maturity on patterns secretion these hormones in Large White x Landrace boars. Four pubertal three post-pubertal boars subjected plasma sampling every twenty minutes for 24 hours. During puberty, varied a manner indicative highly pulsatile mode secretion. Likewise, large fluctuations levels noted at this age, but they not as frequent those LH. In contrast, showed fewer smaller hormone concentrations. The overall mean 0.82 1.04 ng/ml boars, 0.39 0.81 animals. At neither age was there any evidence diurnal variations
