Swine health
Pig diseases can be caused by bacteria, viruses, protozoa, nutritional deficiencies, poisonous substances, internal and external parasites.
Bacterial diseases include swine erysipelas, swine dysentery, infectious poly-arthritis etc. Viral and mycoplasma diseases include African swine fever, swine influenza, enzootic pneumonia of pigs, vesicular exanthema of swine, transmissible gastroenteritis etc. Helminthiasis as a health problem in pigs is mainly caused by worms like the lungworm, ascaris worm etc. Nutritional diseases include piglet anemia, parakeratosis etc. External parasitic infections include mange, lice, jiggers etc.
How to tell that a pig is in bad health:
General signs: dullness, loss of appetite, labored or rapid breathing, sudden deaths, loss of weight, low weight gain and fever usually manifested by shivering of the pig.
Signs expressed on the skin: reddening of the skin or skin discoloration, loss of hair and hardening of some parts of the skin, itching and cracking of the skin.
Other signs: lameness, cough, abnormal nasal discharges, diarrhea with a putrid smell, abnormal content and color of feces and abortions.
Trouw Nutrition Asia Pacific is excited to invite you to join us at the 8th International Symposium on Emerging and Re-emerging Pig Diseases (ISERPD) as we present at the poster session on the groundbreaking topic of "Plant Extracts Impact: Immunity Supplementing Sows for Improved Colostrum Quality and Offspring Performance." Our team of experts has been tirelessly working on this research, and we can't wait to share our findings with you.

Introduction: Worldwide there is growing concern about the increase of antimicrobial resistance. Antimicrobial resistance (AMR) could be considered as the result of (over)usage of antimicrobials (AMs) in human beings and animals. In order to reduce further increase of AMR the government of the Netherlands together with the livestock sectors and vets developed an action plan to reduce the use of AMs, in the assumption that reduction is associated with reduction in resistance. The...

Introduction: Italy is a large pig producer and a system to monitor active ingredients (AIs) consumptions of veterinary medicinal products (VMPs) at farm level is needed. The aims of this study were to develop a tool to record these consumptions and to compare AIs usages with production losses, biosecurity levels and health statuses. Materials and Methods: A data collection software, an XML database and an interactive dashboard were developed...

Introduction: Easiness of injections is an important parameter for animal welfare and operators. This study was done to compare viscosity and syringeability of 5 florfenicol injectable solutions marketed in Mexico or Brazil, under laboratory conditions. Materials and Methods: One 40% florfenicol injectable solution (Maxflor® LA, Virbac) was compared to four 30% florfenicol injectable solutions. Viscosity was measured at ambient temperature and 5°C by...

Introduction: Mycoplasma hyopneumoniae is the primary agent involved in porcine enzootic pneumonia (EP). Different genotypes of M. hyopneumoniae have been described using Multiple Locus Variable-number Tandem Repeat Analysis (MLVA). In our experience it is difficult to perform a MLVA from nasal swab samples due to the sensitivity of some PCRs. In this regard, we have reported the increasing of the sensitivity of p146 locus (Tamiozzo 2011, 2013) developing a...

Introduction: Multiple Locus Variable Tandem Repeat Analysis (MLVA) is a useful method to characterize bacterial strains and understand the transmission chains and sources of infection in order to implement more effective control measures. The present study is aimed to use MLVA technique to characterize M.hyopneumoniae (M.hyo) strains in pigs from wean to finish in the same herd. Materials and Methods: The study was carried out in a three-site herd in...

Introduction: For animal production sites (especially those of very high value, such as genetic production and breeding/reproduction sites), that are expected to be and remain negative for a particular disease agent, an appropriate detection plan for new introduction of undesired disease agents must include both continuous clinical observation and well designed diagnostic sampling/testing protocols. Whereas basic sample size determination methods for disease detection...

Introduction: Cranio-ventral pulmonary consolidation (EP-like lesions) and chronic pleuritis (CP) are common findings in slaughtered pigs. Pleural lesions involving dorso-caudal lobes are suggestive of pleuropneumonia due to Actinobacillus pleuropneumoniae (App). The aims of the present study were to investigate the prevalence of lung and pleural lesions at abattoirs in Italy and to identify major factors potentially associated with the prevalence and the severity of...

Introduction: Piglet mortality causes welfare challenges and economic losses in commercial pig production. Crushing is the most common cause of death, but as an empty stomach is frequently found in crushed piglets, starvation is often a precursor to be crushed. Piglets are born with a limited resource of energy in the form of glycogen and with very little body fat. Thus an abundant amount of sow colostrum and later sows milk is vital for the survival of the piglets. In...

Introduction: Production diseases usually originate from a complex interaction of pathogens, animal genetics and environment. They compromise animal health and welfare, can reduce product quality and increase environmental footprint of pig production and the use of antimicrobials. Production diseases impact farm economy and can result in loss of revenues and extra production costs. However, very limited synthesis on economic impacts of production diseases is available. The goal...

Introduction: Loose housing systems for sows may have increased the occurrence and importance of Ascaris suum. Anthelmintic treatments can result in resistance development. Therefore identification of risk factors and development of alternative control strategies is relevant. The objective of this study was to identify risk factors associated with Ascaris suum egg counts in sows and gilts from intensive farms with loose housed sows. Materials and...

Introduction: Foot-and-mouth disease (FMD) causes severe economical problems in livestock industry because of rapid spread and inducing low productivity. Thus, the administration of vaccines is a highly effective method for preventing FMD. In an effort to prevent and control FMD, Korea is currently implementing a vaccination policy. Despite all the hard work, Korea is suffering from recent FMD outbreaks of serotype O. FMD vaccines were evaluated characteristics, purity,...

Introduction: In 2014 in North Carolina, anecdotal reports of a particularly virulent PRRSV isolate (RFLP cut pattern 1-7-4) were reported by practicing veterinarians. Reports indicated that the isolate was more transmissible, had higher levels of viremia for longer time periods and was more virulent in comparison to other circulating PRRSV strains. The objective of this study was to evaluate PRRS 1-7-4 isolates under experimental challenge conditions. Materials and...

Introduction: Ulcerations in the skin of a pig may be painful and hamper the welfare of the animal if neglected. Serious and untreated ulcerations are reported to the police by veterinary enforcement officers, and often an examination carried out by a veterinary pathologist is requested. A retrospective study of forensic case files concerning ulcerations in Danish pigs from 2000 to 2014 was carried out. The aim of the study was to evaluate the number of cases, the number...

Introduction: Straw is one of the most effective routing materials to reduce tail biting in pigs. A so called foraging-tower (FT) enables to provide only small quantities of straw compatible with liquid manure systems. The focus was on the effect of providing straw by FT for the prevention of tail biting in tail docked pigs. Materials and Methods: The study was conducted from June 2013 to August 2014 in a conventional farrow to finish herd in Germany, which...
