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: Research has documented that non-steroidal anti-inflammatory drugs (NSAIDs) reduce pain and pain related behaviors in piglets. The use of analgesics at the time of piglet processing increases the amount of piglet handling and injections as well as increases the labor for the producer. The ability to give an injection of an NSAID at the same time as an iron product (compounded) would help minimize animal handling and labor. The objective of this study was to...

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: The objective of this study was to evaluate the effects of removing antibiotics (AB) from the diet of 1st and 2nd stage weaners on welfare indicators. Materials and Methods: The study involved a total of 12 pens of 35 pigs each where in-feed antibiotics were either removed (NO) or maintained in the diet (AB) during the 1st and 2nd weaner stages (9 weeks in total). Ten focal pigs were randomly selected from each group (AB, n = 60 and NO, n...

Introduction Numerous reviews have been written to describe the specificities and advantages of the pig model in studies focusing on behavior, nutrition and neuroscience (Kornum and Knudsen, 2011, Roura et al., 2016, Val-Laillet, 2019). Besides the fact that the pig is an animal species of obvious interest in agriculture and human food production, it also has incomparable advantages when it comes to studying the consequences of the nutritional environments, diets or feed in...

For many years reactive oxygen species (ROS) production in biological systems has been considered to be detrimental. However, a pleasant face of ROS has received recently tremendous attention. Indeed, it has been proven that ROS participate in cell signalling, transcription factors regulation and vitagene activation to maintain optimal cellular redox balance and to provide an effective stress adaptation [1]. In fact, redox biology is a very rapidly developing area of modern biological...

Introduction: Since 2001 GD Animal Health in the Netherlands runs a monitoring system on pig health. One pillar of this system is the recording of all telephonic questions concerning health issues. Since 2013 lameness turned out to be the main subject of these questions. A detailed telephonic survey in 2014 revealed that most of the questions on lameness concerned finisher pigs between 3 and 5 months of age. The symptoms reported were acute lameness in more than one leg and...

Introduction: Traditionally, bacteriological diagnostics are based upon colony-morphology and biotyping. During the later years, MALDI-TOF-identification has broadened the spectrum of bacteria that can be identified in laboratory submissions. Four case-stories on potentially important pathogens are presented. Materials and Methods: Case 1: Massive problems with arthritis around weaning. 4 piglets were examined. Deeply cut teeth and swollen joints with...

Introduction Animal welfare has been increasingly included in business agreements and with humane slaughter is a key area of interest (von Keyserlingk and Hötzel, 2015). Retailers, restaurants, and food service companies seek kinder and more responsible farm animal practices (Grandin, 2010; Bayvel et al., 2012). Yet, it is a consensus that changes in attitudes and practices of stakeholders are required to improve farm animal welfare at slaughter (Paranhos da Costa et al.,...

Introduction: Piglet weaning is an interesting model of oxidative stress (OS), but due to large inter-individual variations, there is a need to standardize in vivo response by applying usual challenges, such as vaccination (vacc) and heat stress (HS). The objectives of this trial are the development of a reproducible model of OS and the determination of the most accurate blood biomarkers. The effect of a combination of antioxidants was also investigated. Materials and...
