Swine management

Pig production is the systematic rearing of pig breeds on scientifically based management principles for economic benefit. The main objectives of pig production are to provide consumers with pig meat and related products and to generate income for farmers. Pig production plays a significant role in the livestock industry, providing an important source of protein and other valuable products. The systematic approach to pig rearing ensures that the pigs are healthy and well-cared for, which in turn leads to better quality products and higher yields. The focus on scientific principles and efficient management helps to reduce waste and increase profitability for farmers. A swine producer who masters the art of good management has excellent profit opportunities. This is especially true with disease prevention and control. A healthy herd of good-growing, quality breeding animals — adequately fed and housed — provides maximum profit opportunities for the owner who does not over-spend for facilities and/or feed.

Introduction: Porcine epidemic diarrhea virus (PEDV) and porcine deltacoronavirus (PDCoV) represent new threats to the swine industry. To aid in early detection of virus, monitor shedding, or differentiate viral species, real-time PCR has proven a useful diagnostic tool. The aim of this study was to measure the sensitivity of real-time PCR assays for the detection of PEDV and PDCoV on field samples at different times of the infection. Materials and...

Introduction: Approximately 40 % of Danish swine herds are positive for PRRSV. PRRSV is secreted in nasal and oral fluid and can be detected in serum for weeks after infection. To control PRRSV it is critical to monitor the PRRSV status in different production stages. Information on ongoing PRRSV infection is normally obtained by test of serum which is laborious and stressful for the pigs. The aim of the study was to test if test of oral fluids can replace serum for PRRSV...

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: 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: Postweaning multisystemic wasting syndrome (PMWS) is still one of the major economic problems for the pig industry. To confirm PMWS, it is necessary to fulfil the following diagnostic criteria: 1) specific clinical and necropsy findings; 2) specific histologic lesion and 3) presence of moderate to significant amount of PCV2 by immunohistochemistry (IHC) or in situ hybridization (ISH). The fact that the virus is ubiquitous in pig populations worldwide,...

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: The wean-to-farrow interval is comprised of two stochastic periods, the wean-to-service interval and gestation length. Variation in the wean-to-farrow interval can be affected by many biological factors as well as by management strategies like induced farrowing, multiple weanings/week and products which facilitate single, fixed-time AI like OvuGel®. The opportunity cost consequence of variation in a sow group’s wean-to-farrow interval is the...

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...
