Journal of Dairy Science, 1998 The optimal time of artificial insemination (AI) was determined from data for 2661 AI in 17 herds utilizing a radiotelemetric system for estrus detection that has the potential for continuous 24-h surveillance to monitor behavioral events associated with estrus.

Luteinizing hormone receptor knockout mouse: What has it taught us?
Andrology, EarlyView.Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

The Influence of Selected Factors on Changes in Locomotion Activity during Estrus in Dairy Cows
AnimalsThe objective of this study was the evaluation of the locomotion activity of heifers and Holstein dairy cows during estrus. We have analyzed the locomotion activity using the Heatime RuminAct device on 180 cows (32 heifers and 148 dairy cows) and we ...

Andrology, EarlyView.Abstract The exploration of gender differences in non‐andrological fields was the core focus of a series of discussions, which took place at the Endocrinology Unit in Modena, Italy in the form of the aporetic dialogue of ancient Greece. This second episode reports the transcript of the actual debate on testosterone's role in defining empathic behavior ...

Andrology, EarlyView.Abstract Background Predicting male fertility in farm animals remains a challenge. Seminal plasma (SP) contains a high amount of heterogeneous seminal extracellular vesicles (sEVs), believed involved in reproductive processes and maybe key to understanding male fertility.

Proper detection of estrus is critical in dairy husbandry. Loss of profit due to extended calving intervals, milk loss, and veterinary costs are related to incorrect detection of estrus. Despite enormous progress in the knowledge of reproductive physiology and the development of estrous detection aids, detection of estrus remains a major problem.

Preclinical models for evaluating psychedelics in the treatment of major depressive disorder
British Journal of Pharmacology, EarlyView.Psychedelic drugs have seen a resurgence in interest as a next generation of psychiatric medicines with potential as rapid‐acting antidepressants (RAADs). Despite promising early clinical trials, the mechanisms which underlie the effects of psychedelics are poorly understood.
