Cutaneous application of SecurePig® FLASH, a Pig appeasing pheromone analogue, facilitates adaptation and manages social behavior during feeding in semi-extensive conditions Open
Background Farm animals face several challenges throughout their lives, which can affect both their welfare and their productivity. Promoting adaptation in animals is one way of limiting these consequences. In various animal species, the u…

A systematic approach to defining and verifying descriptors used in the Qualitative Behavioural Assessment of sows Open
Qualitative Behaviour Assessment (QBA) is a welfare evaluation tool that uses a holistic approach to capturing an animal’s emotional state. Lists of QBA descriptors validated to assess pig welfare exist, but their definitions are often not…

A trait or a state - how consistent are tail biting phenotypes in pigs? Open
The physiological, psychological and behavioural traits of tail biting/bitten pigs have been widely studied, with most research focusing on identifying traits to predict tail biting phenotypes (biters, victims, or uninvolved ‘neutrals’). H…

Investigating risk factors behind piglet facial and sow teat lesions through a literature review and a survey on teeth reduction Open
Introduction: Piglet facial and sow teat lesions are the main reported reasons why pig producers routinely practice teeth resection. This is a painful procedure performed on piglets, where their needle teeth are clipped or ground to resect…

A systematic review of the impact of housing on sow welfare during post-weaning and early pregnancy periods Open
Breeder animals are an important focus in farm animal welfare assessments as they typically live the longest lives and are at the greatest risk for suffering due to their longevity. For breeding pigs, the time between the end of lactation …

Cat owners’ perception on having a pet cat during the COVID-19 pandemic Open
Restrictions during the COVID-19 pandemic may affect the lives of pet animals. We aimed to assess the impact of the COVID-19 pandemic on the welfare of pet cats across countries, as well as the owners’ experience in relation to their cat(s…

A High Enrichment Replenishment Rate Reduces Damaging Behaviors and Increases Growth Rate in Undocked Pigs Kept in Fully Slatted Pens Open
One of the difficulties in complying with the prohibition of routine tail docking is a lack of effective alternative solutions to prevent tail biting, especially in fully slatted systems. This study compared three slat-compatible enrichmen…

53 Risk factors for facial lesions in piglets and teat injuries in sows – a review Open
Painful procedures performed on piglets are one of the most important welfare concerns of intensive pig production. For example, teeth resection is a common practice whereby the canine (needle) teeth are clipped or ground to prevent piglet…

Can increased dietary fibre level and a single enrichment device reduce the risk of tail biting in undocked growing-finishing pigs in fully slatted systems? Open
This study evaluated the effectiveness of combined dietary and enrichment strategies to manage tail biting in pigs with intact tails in a conventional fully-slatted floor housing system. A 2 × 2 × 2 factorial design was used. Pigs had eith…

Variations in the Behavior of Pigs During an Open Field and Novel Object Test Open
Tail biting is a serious welfare concern in pig production. It not only causes distress for victims, but may occur where pigs are unable to cope, and become biters. An animal's ability to cope with stressful situations may vary between ind…

Intra-Group Lethal Gang Aggression in Domestic Pigs (Sus scrofa domesticus) Open
Intraspecific coalitional aggression is rare among all species, especially within stable social groups. We report here numerous cases of intraspecific lethal gang aggression within stable groups of domestic pigs. The objective was to descr…

Strategies to manage tail biting in pigs housed in fully-slatted systems Open
EU Council Directive (2008/120/EC) prohibits the routine practice of tail docking to control tail biting in pigs, yet most pigs in Europe are still tail-docked. This is primarily due to a lack of effective solutions with the least economic…

Multi-Step Tail Biting Outbreak Intervention Protocols for Pigs Housed on Slatted Floors Open
Solutions are needed to keep pigs under commercial conditions without tail biting outbreaks (TBOs). However, as TBOs are inevitable, even in well managed farms, it is crucial to know how to manage TBOs when they occur. We evaluated the eff…

Rearing Undocked Pigs on Fully Slatted Floors Using Multiple Types and Variations of Enrichment Open
In fully slatted systems, tail biting is difficult to manage when pigs’ tails are not docked because loose enrichment material can obstruct slurry systems. This pilot study sought to determine: a) whether intact-tailed pigs can be reared w…
