Abstract:
... High circulating progesterone concentrations decrease the responses to stressful situations in farm ruminants. We hypothesized that administering a single dose of long-acting progesterone formulation reduces the stress response of anestrous ewes to weaning. The aim of this study was to compare the behavioral, cortisol, and blood protein responses to weaning of anestrous ewes treated or not, with a ...
... Endogenous hydrocortisone causes detrimental effects on public health and domestic animal products, but the potential mechanisms remain elusive. Hydrocortisone was detected from seventy-two Guanzhong-Black pigs in three replicates (216 samples) (0.00 ± 46.38 μg kg⁻¹), indicating the existence of endogenous hydrocortisone. Herein, we investigated the effects of hydrocortisone on the metabolic signa ...

Abstract:
... Ensuring horse welfare is a central aim in equestrian activities. Training is an important context for welfare, as horses form long-lasting representations of people and actions at a young age. However, only a few studies have addressed horses’ emotional responses during early training with humans. In this study, we followed N = 19 young horses, including naïve yearlings and more experienced two- ...

Abstract:
... In the present study, we aimed to determine the effect of lift farrowing crates on piglet mortality by crushing and on sow welfare. Eighty-four sows were considered in the one-year experiment in three monitoring sessions. In each session, 14 sows were housed in a room with conventional crates (CC), and 14 sows were lodged in a room equipped with lift crates (LC). The sows, of the same genetics, wi ...

Abstract:
... The determination of cortisol concentrations in animal hair appears to be a relatively simple and non-invasive method of assessing chronic stress. This method has advantages but it also has some drawbacks. We discovered that there are specific coat properties and individual factors in animlas that can affect corisol levels and skew the interpretation of results. We removed horsehair from 8 differe ...
