“…Even though it remains unclear as to the exact mechanism through which NPY influenced hypothalamic-release of GHRH in the animal model used in this study, it appears that the site of action may be within the hypothalamus. In previous studies, NPY had no direct effect on GnRH-induced release of luteinizing hormone from bovine anterior pituitary cell cultures [51]. …”

“…Em animais de boa condição corporal, as concentrações séricas de hormônio luteinizante (LH) são mais elevadas que naqueles que apresentam perda de escore corporal (GIL, 2003). Em animais que passam por longos períodos de restrição alimentar, a liberação do hormônio LH pela hipófise é reduzida devido à supressão da liberação do GnRH (DENNISTON et al, 2003 Vacas com maior balanço energético positivo apresentam maior número de folículos grandes nos ovários, portanto maior potencial para produzir estradiol, hormônio que estimula o centro pré ovulatório de LH e que está associado com ovulação e luteinização (PIRES et al, 2010).…”
