Nutritional signals are detected by the central nervous system (CNS) and translated by the neuroendocrine system into signals that alter secretion of LH and growth hormone (GH). Furthermore, these signals directly affect the activity of the pituitary

Estrus and ovulation responses in Matrix-treated gilts may affect ovulation synchrony in response to triptorelin. In experiment 1, estrus and ovulation measures at 12h intervals after last Matrix feeding (LMF) were analyzed. For the 398 gilts that di

The generic GnRH agonist, Fertilan (goserelin), was tested for the ability to induce an LH surge and ovulation in estrus-synchronized gilts. Three experiments were performed to 1) examine the effect of various doses of Fertilan on secretion of LH in

The goal of this study was to determine the immunohistochemical characteristics of peripheral adrenergic OBR-immunoreactive (OBR-IR) neurons innervating adipose tissue in a pig. The retrograde tracer, Fast Blue (FB), was injected into either the subc

Contents The relationship of neuropeptide Y (NPY), galanin (GAL), β-endorphin (β-END) and vasoactive intestinal peptide (VIP) to GnRH neurons were determined during the estradiol-induced LH surge. In experiment 1, 16 ovariectomized (OVX) gilts rece

Studies were conducted to determine whether there is an LH surge generator in the hypothalamus of the pig. In experiment 1, 157-day-old ovariectomized (OVX) gilts received 1.5 microg estradiol benzoate (EB)/kg BW i.m. every 12 h from 0 through 24, 48

The influence of glucose and free fatty acids (FFA) on LH and GH secretion from porcine pituitary cells was examined in culture. Cells were challenged with 10 -9 , 10 -8 , or 10 -7 M GnRH; 10 -9 , 10 -8 , or 10 -7 M [Ala 15 ]-h growth hormone-releasi

The objective of this study was to determine whether AIMAX (a dithiocarbamoylhydrazine derivative) is suitable for determining the effects of norepinephrine (NE) depletion on reproduction in domestic animals. Therefore, the effect of AIMAX (n = 6) on

The role of norepinephrine (NE) in the progesterone (P)-dependent endogenous opioid peptide (EOP) suppression of LH and prolactin (PRL) secretion in the pig was studied. Fifteen ovariectomized gilts treated with P (0.85 mg/kg b.w. i.m.) twice daily f
