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.
The Swine Health Information Center seeks a second round of research proposals to investigate cost-effective and innovative technologies, protocols, or ideas to enhance biosecurity during the wean-to-harvest phase of pig production, due April 28, 2023. Funding for the selected proposals will be provided by SHIC, the Foundation for Food & Agriculture Research, and Pork Checkoff as part of SHIC’s Wean-to-Harvest Biosecurity Program to be implemented over 2023-2024. The first round of...

Introduction: Although current evidence suggests a relatively low prevalence of MRSA in pigs in the USA, concerns remain about spread of multidrug resistance bacteria from the farm environment to swine workers and the wider community. The aim of this study was to characterize antibiotic resistance profiles of SA isolated from growing pigs in the USA. Materials and Methods: Twenty nasal swabs were collected from 36 growing pig sites in 11states in the USA,...

Introduction: Piglets from gilts have poorer performance and health during later life. The objective of this study was to evaluate the effect of sow parity and other lactation parameters on pig welfare lesions in the weaner and finisher stages. Materials and Methods: The study was conducted on a farrow-to-finish commercial farm. At birth, the sex and bodyweight (BW) of 847 piglets was recorded as well as the parity of their dam and the number of piglets born...

Introduction: Tail biting outbreaks rate among the major threats in pig production. To prevent or at least minimize tail biting docking is routine practice in Germany, although it contradicts the Council Directive 2008/120/EC. Many factors, like climate, general health status, stocking density, food and water supply and especially insufficient environmental enrichment have a major impact on the tail biting incidence. In the present study, a straw-filled rooting tower...

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: Tail biting is a global welfare problem in the pig industry leading to significant tail injury and potential carcass rejection. The temporal effects of such injuries and subsequent healing are presently unknown, although limb amputation in humans can lead to abnormal neural activity and decreased nociceptive thresholds. In order to evaluate potential sensitisation following tail damage, we created a model by surgical amputation of tails, and assessed mechanical...

Introduction: To evaluate the effects of removing antibiotics (AB) from the diet of 1st and 2nd stage weaner pigs on the performance of negative behaviours. Materials and Methods: Weaned pigs in a total of 12 groups of 35 pigs each, had in-feed AB removed (NO; n=6) or maintained in the diet (AB; n=6). Groups were observed 1 day/wk between 0900 and 1300h for 3x5min periods each and all occurrences of fights, head knocks, tail, flank and ear biting...

Introduction: According to Danish regulations gilts and sows must be housed in groups from weaning until 7 days before expected farrowing. Mixing sows both after weaning and after mating may/will impair reproduction results and increase prevalence of lameness. A Danish study shows that approximately 90 % of medical treatments in gestation are attributed to lameness. The aim of the current study was to reduce the frequency of gilts and sows being treated for lameness in the...

Introduction: Piglet mortality, mainly within the first 4 days after farrowing, is still an important welfare issue and an economical challenge. Variation in piglet mortality between herds with similar genetic material and physical environment indicates that the herd`s management is a crucial factor. The objective of this survey was to assess the importance of different management routines around the time of farrowing and other farm qualities for piglet survival in...

Introduction: The objective of the present work was to collect preliminary production data on a newly-developed farrowing pen for individually loose-housed sows and to use these results to produce a pen for commercial practice which has a high piglet survival rate and improved sow and piglet welfare. Materials and Methods: The “Sow Comfort” farrowing pen” (7.9 m2) comprises two compartments: a “nest area” and an activity/dunging...

Introduction: Castration procedure is a painful method which reduces welfare and could reduce performance. Some trials demonstrated that meloxicam prior castration procedure in piglets could reduce acute pain decreasing behaviors relates to a lack of welfare. Any study using infrared thermography (IT) was found to evaluate the inflammatory process after castration procedure in piglets. This study aimed to evaluate inflammatory process using IT associated with behavior and...

Introduction: Sow body condition is a critical factor in all stages of the production cycle affecting health, welfare, performance and longevity. Additionally, the direct economic impact on annual costs of unoptimized feeding can be substantial. Therefore, it is important to monitor sows throughout their lifetime to ensure well-being, maximize production efficiency, optimize culling decisions and determine the adequacy of the feeding management practices. Multiple tools are...

Introduction: The farm was a closed herd using AI and comprised 430 breeding sows. Progeny were kept until 10 weeks of age when they were sent to a second unit for finishing. The farm was infected with PRRS virus, as well as enzootic pneumonia (EP) (Mycoplasma hyopneumoniae), pleuropneumonia (Actinobacillus pleuropneumoniae) (APP) and streptococcal meningitis/arthritis (SM) (Streptococcus suis). The farm was planning to replace the weaning...
