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...

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...

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...

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,...

Heavy metals are known to be able cross the placental and blood brain barriers affect critical neurodevelopmental processes in fetus. We measured metal levels (Al, Cd, Hg, Li, Pb Zn) cord of newborns serum same children at 5 years age, compared between individuals with or without (controls) autism spectrum disorder (ASD) diagnosis. The samples were from a biobank associated All Babies Southeast Sweden (ABIS) registry. proposed Bayesian multivariate log-normal model for partially censored...

Shelters are frequently used for fish rearing to improve welfare conditions. In this study, whether Nile tilapia prefers specific shelter colors was evaluated. Thus, preference white, red, blue, green or yellow shelters tested. A high variation of individual responses the among found. Even so, while red clearly avoided by tilapia, a clear-cut could not be concluded. avoiding is recommended, assuming preference, non-preference, as important elements considering Moreover, variability should...

Donkeys (Equus asinus) face a global crisis. The health, welfare, and even survival of donkeys are being compromised as the demand for their skins increases. It is driven by production ejiao, traditional Chinese remedy believed some to have medicinal properties. estimated that ejiao industry currently requires approximately 4.8 million donkey per year. Since there no productive chain skin outside China, activity extractive has resulted in decimation donkeys. Gestation 12 months donkeys,...

Donkeys ( Equus asinus ) are facing a global crisis. Their welfare, and even survival, is being compromised as the demand for their skins increases. This driven by need to supply raw materials produce ejiao , Traditional Chinese Medicine made from collagen extracted donkey skins. Since there no productive chain skin production outside of China, trade an entirely extractive industry that has resulted in decimation some local populations. The demonstrably unsustainable, ethical issues...

Donkeys (Equus asinus) face a global crisis. Their health, welfare, and even their local survival are compromised as the demand for skins increases. Such donkey aims to supply ejiao industry. Ejiao is traditional remedy made from collagen of skins. Some people believe it has medicinal properties. It estimated that industry currently requires approximately 4.8 million per year. Although future donkeys still uncertain, we must guarantee life free suffering animals under our responsibility. The...

In confrontations, many behaviors are based on visual information. To establish the importance of signals in aggression cichlid fish, we observed behavior groups three juveniles Nile tilapia (six each condition), for 30 minutes under two extremes light condition: high luminosity and low (dark condition humans – only infrared light). The average number bites chases was lower than luminosity. We conclude that diminishes but does not eliminate fights, fish can rely nonvisual senses intensity to...

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...
