The aim of this study was to measure hair cortisol and dehydroepiandrosterone (DHEA) concentrations in naturally Taenia solium infected non-infected control pigs assess the effect an environmental change on aforementioned parameters. Three patches were obtained from 13 T. 15 controls sows, respectively corresponding 3 time points (prior to, at approximately two weeks after arrival research facility). Cortisol DHEA extracted using methanol analysed by radio immune assay. Mean significantly...
The aim of this study was to analyze the feasibility and reliability using hair as a matrix determine dehydroepiandrosterone (DHEA) sexual steroid concentrations cortisol/DHEA ratio in fattening pigs. results could be also used plan future research identify threshold values order set up strategies control allostatic load increase resilience pigs before slaughter. conducted on 107 commercial crossbred rearing samples were taken by shaving at age 36 weeks, hormones measured solid-phase...
To investigate how long relocation modified hair cortisol concentrations in New Zealand white rabbits, 19 rabbits were subjected to a change their breeding facility at the beginning of trial and then kept under stable environmental conditions. Hair samples collected time arrival nonhuman animal 40-day intervals from same skin area for up 440 days after animals' facility. A period effect on concentration was found (p < .01). The transfer new might have induced an increase...
The aim of the study was to perform an investigation on concentration 19 minerals and cortisol in red deer (Cervuselaphus) hair, a matrix that is easy collect with non-invasive painless sampling, able represent integrative values long-term substance concentrations, give useful information, also when performed dead animals, given its extreme stability over time. In thirty-five animals were included, coming from two different sides valley Stelvio National Park, where official water analysis...
The experiment was aimed to evaluate the usefulness of hair cortisol concentrations (HCC) in revealing activation hypothalamic-pituitary-adrenal (HPA) axis due passage young bulls from genetic rearing stations artificial insemination (AI) centre and influence this on testosterone (HTC). Hair samples 33 yearling were collected at time arrival (ST1) AI 3 more (ST2, ST3, ST4) monthly intervals. After end quarantine each animal submitted standard procedures for collection production semen....
Radioimmunoassay (RIA) methods have always represented a technique of choice for the determination steroids in biological samples. The Amplified Luminescent Proximity Homogenous Assay-Linked Immunosorbent Assay (AlphaLISA) is now emerging as new-generation immunoassay technology that does not require washing/separation steps. aim this study was to adapt Perkin-Elmer's AlphaLISA kit wool cortisol and compare it with RIA assay. Wool from lambs, 35 at birth (A0) 54 two months old (A2),...
The aim of the present pilot study was to determine allostatic load by analysing hair cortisol and dehydroepiandrosterone‑sulphate (DHEA‑S) commercial pigs belonging different farms having good overall animal welfare according CREnBA (Centro di Referenza Nazionale per il Benessere Animale - Brescia, Italy) assessment protocol. conducted on 86 three with a grade higher than 8 CReNBA evaluation system. Hair samples were taken shaving sows 1‑10 days after weaning (Farms 1 2) at age 8‑10 months...
Contents The aim of this research has been to evaluate the presence anomalies in ovarian cycle activity during postpartum and verify whether 72‐hr dietary fasting dominance phase, phase before ovulation, might modify follicle population. evaluated 30 Italian Friesian cows starting from 20 days until 211 lactation. Long oestrus brief dioestrus or scarce luteal have main found through measuring progesterone concentrations whey. Until 100 lactation, BCS values problematic animals significantly...
Importance of the work:The care calves on dairy farms between birth and weaning can improve their long-term development growth.In fact, a poor newborn health status high allostatic load may adversely affect in cows.To determine cortisol, dehydroepiandrosterone (DHEA) sulphate (DHEA-S) individually is useful for an understanding individual state, being biomarkers hypothalamic-pituitary-adrenal (HPA) axis activity.Objectives: As preliminary study, to investigate hair concentrations DHEA,...

During the last intrauterine fetal stage of development and neonatal period hypothalamic-pituitary-adrenal axis (HPA) is a key system. Apart cortisol, adrenals produce dehydroepiandrosterone (DHEA), major steroid produced by fetus itself, so that it could be considered as marker offspring HPA activity. Non invasive, long time-frame retrospective hormonal levels analysis were performed in hair humans animals, but not newborn puppies, DHEA never investigated puppies. This study was aimed to...
Adrenal hormones, ACTH plasma concentrations and the ultrasonographic evaluation of adrenal glands are considered complementary in clinical evaluations hypothalamic–pituitary–adrenal (HPA) axis function several species. In dogs, age, size weight have a significant effect on glands. neonatal foals, measurements been demonstrated to be reliable; however, individual variables features has not investigated, usefulness gland ultrasonography is still known. The aims this study were: (i) provide...
Adrenal gland ultrasonographic measurements are useful in clinical evaluation of patients with adrenal dysfunction several species. In human healthy neonates, the size glands decreases during first days life. Ultrasonography was demonstrated to be feasible neonatal foals. The aims this study were describe a technique for measurement test its reliability foals, and assess any variation five life foals.First, retrospectively obtained by three observers 26 images 13 sick interobserver...
