Some farming methods have ignored the pigs’ needs by treating them as production units rather than fascinating and intelligent creatures with innate behavioural and physical needs.
Pigs are sensitive to extremes of climate and have no sweat glands (except for on the tip of the snout) nor thick hair cover, relying on fat for insulation. In cold weather pigs often huddle to keep warm, whilst in warm weather they wallow in water and mud to keep cool. Pigs forage and root for food (a strong natural behaviour), and eat a wide range of vegetables and animal products, including carrion. In terms of senses, pigs rely on smell and hearing more than vision. They have a wide range of vocalisations and a good ability to locate odour sources.
Pigs prefer to live in stable families or small groups. However, they can be aggressive to each other, especially if unfamiliar animals are mixed. Boars are often solitary. Contrary to popular belief, pigs are clean animals and if given properly designed living accommodation, will always tend to use one particular area for dunging, thereby keeping their lying/sleeping area clean.

Introduction: Most common influenza A virus (IAV) control measures include sow vaccination using prefarrow, mass or a combination of prefarrow and mass vaccination protocols with either commercial, autogenous or both vaccines. Piglets prior to wean are important in the maintenance of influenza infections in breeding herds as well as in the dissemination of the virus into wean-to-finish facilities. The aim of this study was to evaluate the effect of sow vaccination...
Introduction: Airborne transmission of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) has been known for a long time. Most experiments were performed using type 2 PRRSV and fairly little information is available on the spread of type 1 PRRSV via aerosols. The aim of this study was to compare 3 different air sampling systems for their ability to detect aerosolized type 1 PRRS modified live vaccine virus. Materials and Methods: Three different air...
Introduction: Routine tail docking is not permitted in the EU. This is documented in Council Directive 2008/120/EC, which defines the minimum standards of welfare for pigs. Nevertheless tail docking is very common in all countries with a dense pig production as a precaution to prevent tail biting. Farmers’ organisations and the ministry of agriculture in North Rhine-Westphalia, Germany signed a voluntary declaration in 2014 to develop other means to avoid tail...
Introduction: Intradermal (i.d.) application of vaccines offers an improved hygienic standard compared to intramuscular (i.m.) injection. While previous studies confirmed similar immune responses in animals vaccinated i.d. and i.m., studies on consequences on animal behaviour are still lacking. Therefore, this study evaluated welfare aspects of i.d. and i.m. vaccination in suckling piglets. Materials and Methods: The study was carried out in three batches in a...
Introduction: The EU has prohibited the use of gestating crates for pregnant sows. However, keeping pregnant sows in an individual crate is still widely used in Asian countries. As modern type of group housed sows with individual feeding, electronic sow feeding (ESF) system is introduced in EU. However, a few studies were conducted to figure out the long-term and carry-over effects of static group during gestation to lactation on reproductive performance and physical activities...

Introduction: Effects of 5 to 150 ppm gaseous ammonia onto respiratory health and production data in pigs have been described in literature with varying results. Ammonia is known to cause oxidative stress in epithelial cells, to irritate nociceptors and to disturb the mucocillary clearance. In addition, a pH-shift within the epithelial lining fluid covering the airways with the consequence of an efficacy loss of pH-dependent natural antibacterial peptides is assumed. In...
Introduction: Cooperation and joint technical knowledge of vets and farm managers (experts) are needed for effective pig farming. They have a real influence on production indices and on manifestation and predisposing factors of Porcine Respiratory Disease Complex (PRDC). At the same time the ineffective farm management is responsible for imprudent overuse of antibiotics and economic losses. In this study we surveyed Hungarian, Czech and Slovak swine farm experts’ opinion...
Introduction: Animal welfare, has been traditionally evaluated by measuring level of aggression and stress parameters. However, feeding behavior can also provide a valuable indication of comfort or stress for gestating sows in large groups, when fed with ESF systems. Materials and Methods: The study was conducted at Albesa-Ramadera a 3300 sow, Site 1 farm, based in Catalonia, Spain. The farm has large group gestation (128 to 175 sows per group) and utilizes...
Introduction: Preweaning mortality of piglets remains a welfare as well as an economic concern in commercial swine herds. Post mortem examination can give insight in specific preventive measures. Materials and Methods: A thorough investigation of preweaning piglet mortality was conducted in 14 loose housed Norwegian piglet producing herds. All dead piglets from one batch of sows in each herd, in total 1216 piglets from 378 sows, were collected for...
Introduction: Claw lesions in piglets are common. The neonatal claw is sensible for factors such as floor temperature and roughness, and possible residuals from disinfectants. Also selenium (Se) intoxication and ergot alkaloids have been related to claw lesions. The present case describes the occurrence of hemorrhagic claw lesions in neonatal piglets of a commercial farrow-to-finish pig herd in Flanders. Materials and Methods: The herd consisted of 270 JSR...
Introduction: Improvac® (Zoetis, Florham Park, NJ, USA; marketed as Innosure® in Colombia) is an anti-GnRF vaccine for the immunological castration (IC) of male pigs for the control of boar taint. However, there is very limited information available about the effects of IC on female pigs by temporal suppression of estrus. The objective of this study was to compare performance and carcass quality of immunocastrated vs. normally maturing females raised in a...
Introduction: In 1998 the Dutch government issued that from 2013 sows must be housed in social groups within 5 days after insemination, in addition to EC directive 2008/120. In 2014, the government issued a project to aid farmers, which had reported, on request, negative effects of group housing in the first 4 weeks on welfare and reproduction (n=347), to overcome these effects. Focus of the project was on the interventions to chronic physical stress, as this is an important...
Introduction: Tail biting is a serious welfare problem in pigs, causing substantial economic losses. In the majority of the EU countries, tail docking is used to reduce the incidence of tail biting. However, many of the risk factors for tail biting are related to suboptimal management, and tail biting can be reduced by corrective management decisions. There are few studies on which preventive measures producers themselves value as most important. Materials and...
Introduction: Swine brucellosis outbreaks due to Brucella suis biovar 2 (B. suis 2) occur sporadically in continental Europe. Control and eradication is based on O-polysaccharide (O/PS)-based serological tests and full stamping out of infected herds. However, these tests frequently return false positive serological reactions (FPSR) due to infections with other gram-negative bacteria sharing O/PS epitopes. Previously we proved that a skin test using O/PS free cytosolic...
Introduction: Temporary Veterinary Inspectors (TVIs) detain slaughter pigs ante mortem (AM) for closer inspection if they have concerns regarding their health and welfare. In this study, we evaluated 164 detained pigs, all passed as fit for slaughter, to investigate if there is a relationship between the AM status of detained pigs and their condemnation level post mortem (PM). Materials and Methods: Data collection took place over 5 days in a single Irish...
Introduction: Hoof lesions, which are very common in modern sows, were associated with high risk of early culling and compromised welfare of sows. Some hoof lesions were also associated with decreased litter weight, increased pre-weaning piglet mortality and higher odds of stillborn and crushed piglets. Evidently, if hoof lesions negatively affect not only sow longevity but also the important reproductive parameters which determine the utilisation of breeding herd’s...
Introduction: Automatically collected feeder data may be used to predict tail biting in finisher pigs. Materials and Methods: Pen-level feeding behaviour and growth were investigated in relation to injurious tail biting (ITB), defined as visible wounds, from 10 weeks before to 4 weeks after the first ITB case in the pen. The data set included 36 pens of 10-12 intact boars between 43 and 148 kg, with average pen weight at ITB onset between 78 and 137 kg. A tail...
Introduction: During slaughtering procedure, every animal should be unconscious chiefly to avoid inflicting undue pain during bleeding. Exsanguination without prior stunning is an extremely controversial practice from the standpoint of animal welfare because some animals take a long time to lose brain function. CO 2 stunning can be reversible or irreversible; pigs may recover consciousness before dying, such that the time between stunning and exsanguination is a...
