Boars housed in commercial conditions are often pens or individual crates, and subjected to low-stimulus environments, which may affect the expression of normal species-specific behaviors compromise its health welfare. Breeding boars’ has been poorly reported scientific literature, as well their physiology circadian rhythm cortisol. Moreover, an environmental enrichment for breeding boars, far we know, not studied lacking impact on how it can improve Thus, aimed evaluate behavior salivary...
Aggressive interactions, and their consequences, are the most important causes of poor welfare in piglets. behaviour can be modulated by prenatal neonatal environment several species. Commercially kept pregnant sows often subjected to food restriction, which compromise welfare. Limited information is available on consequences sow hunger during pregnancy outcomes for High fibre diets mitigate feeling and, consequently, it may improve productivity measures. The aim this study was assess...
Some effects of expressing stereotypic behaviour have not yet been elucidated. During gestation, the environment has potential to interfere with offspring development and prenatal or longer-term consequences. We tested hypothesis that occurrence during gestation could affect phenotype offspring. Twenty-eight pregnant sows were studied, by comparing two groups differing in amount stereotypy shown. analysed emotionality from showing high low frequency using open field novel object tests. In...
Introduction Boars are often housed in stressful environments on commercial farms, experiencing poor welfare. These conditions may cause epigenetic changes the boars' gametes, which could potentially be transmitted to their offspring. We aimed investigate effect of three different boars housing survival, aggression, and nociceptive responses Methods For four weeks, 18 were systems: crates (C;n=6), pens (P;n=6), enriched (E;n=6). The environmental enrichment was provided twice daily...
We hypothesized that sham-chewing expressed by the dam during gestation affects fetus programming. The goal of this study was to assess effects maternal on offspring welfare indicators, such as behavior and physiology. Sows exhibited consistent at least two 6 days observation (N = 7) were compared with sows had never performed (non-sham-chewing sows; N 4) these days. Salivary samples from piglets collected cortisol concentrations analyzed hypothalamic pituitary adrenal (HPA) axis activity is...
In commercial pig breeding farms, boars are often exposed to stressful situations, such as confined housing conditions, inadequate environmental temperature, food restriction, lameness, diseases, among other challenges. Confined crates, reported a major source of stress for pregnant sows, and were banned in the UK Europe, however there is limited information about impact this system boars. The goal study was investigate three different conditions consequence on testicles. We studied 27...
Abstract Experiences during gestation can alter the mother’s behavior and physiology, thereby potentially affecting behavioral physiological development of offspring. In livestock, one common challenge for pregnant animals is lameness: a multifactorial condition that causes pain, stress, resulting in poor welfare outcomes. Since maternal pain affect offspring development, we aimed to quantify response 142 piglets born from sows with different degrees lameness pregnancy. Gait scores 22...
The United Kingdom and European Union have banned crates for pregnant sows. However, animals are kept in a restrictive environment up to four weeks after mating, leading stress different responses of the animals' immune system. Here, we used vaginal flushing gilts investigate whether housing systems or an experimental inflammatory challenge with lipopolysaccharide (LPS) can modify gilt microbiome. Alpha-diversity indices showed differences microbiota housed under (q = 0.04). Shannon...
Epigenetic mechanisms are important modulators of neurodevelopmental outcomes in the offspring animals challenged during pregnancy. Pregnant sows living a confined environment with stress and lack stimulation which may result expression stereotypies (repetitive behaviours without an apparent function). Little attention has been devoted to postnatal effects maternal offspring. We investigated how pregnant affected neuro-epigenome their piglets. focused on amygdala, frontal cortex,...
The objective of this study was to evaluate the effects stereotypic behavior on productivity measures in sows. Frequent expression stereotypies by pigs has been reported, even when are not maintained crates. This is only observed animals kept captivity and a wide-range welfare indicator, since it considered develop situations chronic stress or frustration. When comparing groups sows showing low high frequency stereotypy expression, we found that did affect productivity. Moreover,...
The goal of this study was to assess whether or not a separation period 2 h is stressful for jennies and foals, as measured by changes in behaviour, salivary cortisol, milk production. This reviewed approved the Committee Use Care Animals Research (CEUA) School Veterinary Medicine Animal Science University São Paulo. Fourteen multiparous Pêga (245 kg average body weight) their foals were assessed from day 45 135 lactation. Dams separated prior milking. Behavioural assessments saliva samples...
Introduction The welfare of breeding boars is often overlooked, resulting in limited scientific data to foster discussion the topic. We aimed investigate effect different boar housing conditions on their offspring’s emotionality. Methods Eighteen were housed three conditions: crates (C; n = 6), pens (P; or enriched (E; 6). Boars distributed by semen quality (SQ; high, medium, low). Three pools used inseminate 13 gilts outdoor paddocks. At 25 days age, 138 suckling piglets subjected open...
The objective of this study was to reach a diagnosis the living conditions abandoned donkeys kept in restricted farm area through assessment their welfare level utilizing AWIN protocol as methodological tool. These animals were supposed be sent slaughter, but after activity temporarily banned, they by traders. associated with general environmental and sanitary conditions. Information regarding mortality rates also gathered. According results, these acceptable some areas, despite insufficient...
The anatomical variations of the maxillary septum and septal bullae can generate challenges during interpretation radiographs horses' heads make it difficult to accurately identify sites affected in sinus disorders. description radiographic appearance these structures is currently scarce scientific literature. This work aims describe characteristics horses. Six chemically preserved equine cadaver were used which, after being submitted osseous flap, its respective identified. Radiographic...
Abstract The dorsal and ventral nasal conchal bullae sinuses are part of the complex equine paranasal sinus system commonly affected by secondary sinusitis. However, radiographic anatomy is poorly reported in literature. present study aimed to describe anatomical characteristics mature horses. Six cadaveric heads without or dental disorders were studied. A maxillary sinusotomy was performed identify sinuses, allowing application radiopaque contrast medium these structures. Afterward, same...
Abstract Experiences during gestation can alter the mother’s behavior and physiology, affecting development of offspring, including organization their brains emotional system. In livestock, one common challenge for pregnant animals is lameness: a multifactorial condition that causes pain, stress, compromises welfare. Since pain experienced affect offspring development, we aimed to quantify outcomes 156 piglets born from sows with lameness pregnancy. Gait scores 22 group-housed were assessed...
