To assess the impact of acute caloric shortage on reproduction, rabbit does were either fed
ad libitum (control, AL), or fasted for 24 (STF) or 48h (LTF) before induction of ovulation with …

Contents Leptin may play a role in the endocrine‐metabolic processes that guarantee the
physiological course of lactation in dairy cattle. This study was aimed at determining the …

Early gestation may be the best period for sows to recover body reserve losses from
previous lactation. The aim of this study was to investigate the effect of different levels of …

Ghrelin is a peripheral circulating hormone, mainly released from the stomach, which can

Background: In vitro data have shown conflicting results in terms of the effect of leptin on
granulosa cells steroidogenesis. Aim: The aim of the present study was to investigate the …

We describe for the first time a 245 bp fragment of the porcine leptin gene promoter in the
proximity of the transcription start site. Altogether, 720 pigs were screened with the PCR …

Background Leptin has been measured in human in saliva samples. However, the low leptin
concentration found in this biological fluid makes necessary the use of high sensitive …

Introduction: The influence of ghrelin on different organs has been studied recently, eg in the
regulation of pituitary hormone release, regulation of energy homeostasis, glucose …
