There has been limited investigation of parturition in the bitch and there is little information published on clinical and obstetrical examination other than opinion and anecdote. While there are substantial data on haemodynamic and vascular changes during normal parturition in humans, little is known about the physiological events in the dog. This...
The objective was to evaluate the influence of varying plasma progesterone (P4) concentrations throughout the luteal phase in dairy cows on PGF2a production (assessed as plasma concentrations of 13,14-dihydro-15-keto-PGF2a; PGFM) following treatment with estradiol-17b (E2) or oxytocin (OT). In all experiments, time of ovulations was synchronized wi...

This study was done to verify if the lack of increase of milk fat content observed in Alpine dairy goats under once daily milking (ODM) compared to twice daily milking (TDM), results from disturbances of animals and/or milk ejection reflex. In this respect, we determined the milk yield and composition in the same 12 multiparous Alpine dairy goats w...

In vitro, nitric oxide (NO) inhibits the firing rate of magnocellular neurosecretory cells (MNCs) of hypothalamic supraoptic and paraventricular nuclei and this effect has been attributed to GABAergic activation. However, little is known about the direct effects of NO in MNCs. We used the patch-clamp technique to verify the effect Of L-arginine, a ...
