Hair may be a useful matrix to detect cumulative cortisol concentrations in studies of animal welfare and chronic stress. The aim this study was validate protocol for detection hair from dairy cattle by enzyme immunoassay (EIA). Seventeen adult Holstein–Friesian cows were used during the milking period. concentration assessed 25-day-old samples taken frontal region head, analysing black white coloured separately. Concentrations metabolites determined faeces collected twice week same period...
The measure of corticosterone (CORT) in feathers has been recently recognized as a valid and easily obtainable chronic glucocorticoids secretion avian species. This provides meaningful interpretations how individuals respond to environmental perturbations. growing interest the public toward animal-food production welfare shows need for improving expanding objective tools evaluate this issue. present study evaluates whether it is possible detect CORT broiler feathers, thus, assess if would be...
The study of fish stress is usually assessed by measuring blood cortisol.Nevertheless, provides only a snapshot the hormonal profile at one point in time.An alternative source cortisol may be found scales, providing new approach for assessing long-term levels.The present aimed to develop and validate methodology detecting scales goldfish (Carassius auratus).The highlights importance an initial isopropanol washing procedure completely eliminate external contaminations cortisol.Additionally,...
Ensuring high standards of animal welfare is not only an ethical duty for zoos and aquariums, but it also essential to achieve their conservation, education, research goals. While some species, assessment frameworks are already in place, little has been done marine animals under human care. Responding this demand, the committee European Association Aquatic Mammals (EAAM) set up a group experts on science, cetacean biology, zoo medicine across Europe. Their objective was develop comprehensive...
Ensuring welfare in captive wild animal populations is important not only for ethical and legal reasons, but also to maintain healthy individuals populations. An increased level of social behaviors such as aggression can reduce by causing physical damage chronic stress animals. Recently, cortisol hair has been advanced a non-invasive indicator quantify long-lasting many species. The sensitivity behavior concentration was evaluated several groups dorcas gazelles (Gazella dorcas). Four...
Contemporary zoos house polar bears (Ursus maritimus) to serve the conservation efforts of these institutions. However, evidence behavioural problems in captivity has highlighted need for methods assess bear welfare, why valid and feasible animal-based welfare indicators are a prerequisite. Qualitative Behaviour Assessment (QBA) been used emotional state various species. This study therefore aimed ability QBA discern zoo-housed bears, further investigate its validity through associations...
Cortisol levels in fish skin mucus have shown to be good stress indicators farm exposed different stressors. Its applicability free-ranging animals subject long-term environmental stressors though remains explored. The present study was therefore designed examine whether cortisol from a wild freshwater (Catalan chub, Squaliuslaietanus) are affected by the habitat quality. Several well-established hematological parameters and concentrations were measured blood compared variations values...
Horse transportation for temporary relocation during rest periods is a common and widespread practice among horse owners, either from sport competition or working tasks. This study aimed to determine the effect of period multiple factors associated with on hair cortisol concentrations (HCCs) in horses. Additionally, this reports seasonal HCCs growth over year. Thirteen police horses, Pure Spanish stallions various ages (5–13 y), were selected participate study. Hair sample collection was...
Long-term mark-recapture studies are essential for bat conservation. Over the last decades, millions of bats across Europe and America have been marked with forearm rings this purpose. Although it is considered a cost-effective method compared to Passive Integrated Transponders (PIT) tags, direct injuries from using reported since their very first use. Yet, impact on bats' welfare has not systematically evaluated remains highly controversial issue among scientific community policymakers....
Assisted reproductive technology (ART) can benefit from the features of microfluidic technologies, such as automation time-consuming labor-intensive procedures, possibility to mimic in vivo environments, and miniaturization required equipment. To date, most proposed approaches are based on polydimethylsiloxane (PDMS) platform substrate material due its widespread use academia, despite certain disadvantages, elevated cost mass production. Herein, we present a rapid fabrication process for...
Deflighting zoo birds is a practice that receives increasing criticism due to its presumed incompatibility with animal welfare. To our knowledge, this the first approach address problem in scientific way. do this, we compared feather corticosterone (CORTf) from Greater Flamingos (Phoenicopterus roseus, n = 151) of different flight status (i.e., pinioned, clipped, airworthy) twelve zoological institutions. complement hormone measurements, behavioral observations (scan samplings) were...
Concentrations of different steroid hormones have been used in cows as a measure adrenal or gonadal activity and, thus, indicators stress reproductive state. Detecting cortisol and progesterone cow hair provides long-term integrative value retrospective gonadal/placental activity, respectively. Current techniques for detection require hormone-extraction procedure that involves time, several types equipment, management reagents, some assay procedures (which can also be time-consuming destroy...
Society is showing a growing concern about the welfare of cetaceans in captivity as well wild threatened by anthropogenic disturbances. The study physiological stress response increasingly being used to address cetacean conservation and issues. Within it, newly described technique extracting cortisol from epidermal desquamation may serve non-invasive, more integrated measure cetacean’s welfare. However, confounding factors are common when measuring glucocorticoid hormones. In this study, we...
One of the conservation measures globally near-threatened cinereous vulture is restoring populations via translocations, with some vultures originating from breeding centers. These centers need to have reproductive success, and securing good welfare levels should be a priority due negative implications compromised has on reproduction. Thus, assessing in essential. Remote methods preferred, such as behavior analysis use space using camera systems. The study's first objective was develop an...
The most common feather sampling method for corticosterone measurement is by plucking the feathers from bird’s skin. This procedure performed on living, restrained birds qualified as an animal experiment according to German/European legislation, which has be applied competent authorities. Directive 2010/63/EU requires full implementation of 3-R Principle Russel and Burch in experiments, means not only replace use animals, but also reduce number animals used refine procedures whenever...
