Equine Veterinary Journal, EarlyView.Abstract Background In‐hand breeding involving restraint methods is likely the most common practice in the horse breeding industry worldwide. However, welfare issues that arise from such management have not been investigated in detail. Objectives (1) To investigate whether the mares show increased stress responses during in‐hand breeding using (a) a ...

Estrous cycle manipulation in dogs
Clinical TheriogenologyDomestic dogs provide a unique challenge to the veterinary practitioner to manipulate estrous cycle. Due to an obligatory 120-day anestrus, dogs cycle much less frequently than other domestic species. This can pose a problem for owners and breeders wishing to produce pups at a certain part of the year or temporarily prevent pregnancy due to competition,

Mouse Estrous Cycle Identification Tool and Images
PLoS ONE, 2012 The efficiency of producing timed pregnant or pseudopregnant mice can be increased by identifying those in proestrus or estrus. Visual observation of the vagina is the quickest method, requires no special equipment, and is best used when only proestrus or estrus stages need to be identified.

TRPM3 activation causes CGRP release in trigeminal neurons: Implications for migraine mechanisms
Headache: The Journal of Head and Face Pain, EarlyView.Abstract Background The transient receptor potential melastatin 3 (TRPM3) ion channel has been implicated in sensory modulation and pain transmission and may contribute to migraine pathophysiology through calcitonin gene‐related peptide (CGRP) release in the trigeminovascular system. This study aimed to investigate TRPM3 activation and its role in CGRP

Hypothalamic Expression of KiSS1 and RFamide-related Peptide-3 mRNAs during The Estrous Cycle of Rats [PDF]
International Journal of Fertility and Sterility, 2013 Kisspeptin and RFamide-related peptide-3 (RFRP-3) are known to affect GnRH/luteinizing hormone (LH) in several species, including the rat. It has been hypothesized that GnRH/LH changes during the rat estrous cycle may result from changes in the ...

Reinforcement learning across the rat estrous cycle
Psychoneuroendocrinology, 2019 Reinforcement learning, the process by which an organism flexibly adapts behavior in response to reward and punishment, is vital for the proper execution of everyday behaviors, and its dysfunction has been implicated in a wide variety of mental disorders.

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Twin births in dairy cattle are rare but present significant challenges for animal welfare, as both the health of the cow and the calves are affected. This causes economic losses, which prompts breeders to select against twin births and identify associated risk factors.
