Introduction: The antibiotic resistance of field strains of Brachyspira hyodysenteriae has increased in the last years in Spain as well as in other countries due to the high use of antibiotics for the control of swine dysentery (SD). For this reason, antimicrobial susceptibility tests are becoming essential for an effective control of this disease. Our objective was to study the antibiotic susceptibility of Spanish field strains of Brachyspira hyodysenteriae in...

Introduction: Mesocolon edema syndrome is recognized as a common cause of diarrhea in pigs less than 2 weeks of age, and has been associated with neonatal colonization by Clostridium difficile , C. perfringens , or often as a combined infection. In the United States, C. perfringens type A is increasing in prevalence, but C. difficile colonization and subsequent enterotoxemia is still an important cause of the syndrome. In this study, we directly...

Introduction: Infection with C. difficile may have subclinical signs and light manifestations of disease; its transmission is fecal-oral route, considered as the principal way of contamination. As bacterial infections have negative impact, on the roster, this study has relation with the ways of transmission of C. difficile in swine. This study was to evaluate the transmission of C. difficile via aerogen using PCR and histological section of...

Introduction: Clostridium perfringens type A enteritis is a frequent disease of the newborn piglets with a major economic impact in the Czech Republic and important swine producing countries as well. Different antimicrobials may be used for treatment of piglets affected by clostridial enteritis. There are only a few reports on antimicrobial susceptibility of C. perfringens from pigs. Overall, the most common resistance in C. perfringens is to...

Introduction: Cystoisospora (syn. Isospora ) suis is a leading cause of diarrheal disease in neonatal piglets and the disease is related to considerable economic losses. The metaphylactic treatment with toltrazuril 3 to 5 days after birth is a common control measure practiced in many countries. Another essential practice is the prevention of neonatal iron deficiency anaemia as piglets are born with small iron reserves (35 to 50 mg) and sow milk contains...

Introduction: The purpose of this study was to demonstrate the economic benefit and improved yield of groups of gilts vaccinated with SUISENG®, on a farm with a high prevalence of neonatal diarrhoea caused by E.coli/Clostridium . Materials and Methods: 49 clinically healthy, PRRSV-positive and ADV-negative gilts were selected on a farm with 800 sows, and divided into 4 groups, 2 vaccinated (V1 n=13; V2 n=12) and 2 not vaccinated (NV1 n=12;...

Introduction: Clostridium perfringens is a gram-positive bacteria that can cause diarrhea and is commonly transferred from the sow to the piglet. The objective of this study was to evaluate dietary addition of a Saccharomyces cerevisiae fermentation product during late gestation through a 21 d lactation on sow and litter performance, milk components, and fecal Clostridium perfringens. Materials and Methods: On d 93 of...

INTRODUCTION Phosphorus is an essential mineral for the formation and maintenance of bone structure, playing additionally a number of functions in the body. According to UNDERWOOD & SUTTLE (1999), phosphorus is found in a high concentration in bone tissue where together with calcium they form hydroxyapatite, which is the major constituent of the skeleton. Phosphorus portion not related to the structural function in the body is contained in high-value organic molecules,...

Introduction Porcine Epidemic Diarrhea Virus (PEDV) is an enveloped single-stranded positive-sense RNA virus that was first identified in the United States in May 2013. Epidemiological and controlled experiments have shown that complete feed or feed components can be one of many possible vectors of transmission of PEDV. 1 Previous research has shown that a 2% and 1% mixture of caproic, caprylic, and capric acids can reduce the risk of PEDV in a complete swine diet....

Introduction Manganese is an essential trace mineral that is a key component in carbohydrate, lipid and protein metabolism. According to the NRC, 2 the quantitative requirement for Mn for nursery and finishing diets ranges from 2 to 4 ppm. Assuming bioavailability is not a concern, many swine diets today meet the NRC 2 estimated requirement for Mn from the major dietary ingredients before a trace mineral premix is added to the diet. However, due to the...

1. Introduction With increasing public awareness regarding pig welfare, gestating sow housing systems are currently changing around the world to group-housing. While the legislation on sows’ group-housing was adopted in 2001 in Europe, the new Canadian regulation was enacted in 2014. The Canadian Code of Practice for the care and handling of pigs requires that all newly built facilities or those undergoing renovation must house sows in groups during gestation, or provide...

Introduction As many production systems are transitioning from individual gestation stalls to different styles of group housing, there are new challenges for data collection in the gestation barn. Commonly referred to as electronic sow feeders (ESF), computerized feeding stations have been available for more than 30 years as a method used to control the variability of sow intake (Trottier and Johnston, 2001), and now are becoming a powerful tool for sow...

A presentation prepared for the 24th International Pig Veterinary Society Congress and 8th European Symposium of Porcine Health Management at the Royal Dublin Society (RDS) Dublin, Ireland 8th June 2016. Porcine reproductive and respiratory Syndrome Virus (PRRSV) is the most economically significant infectious disease of swine worldwide. Due to the great impact of PRRS in many key swine producing areas of Asia, Europe and the Americas, the epidemiological situation created by...

There are several different genetic technologies that have been used to improve trait performance for pig farmers. Some examples would include: a) Terminal Cross Mating System: this is simply using a crossbred female composed of breeds that are best for reproduction as the maternal line animals. The most common examples are the use of a Landrace/Large White F1 female as the parent female. This allows the best breeds for reproduction to exert...

Introduction The present work addresses the use of data in improving decision making and farm productivity, one of the aspects that has generated more interest in swine production in recent years. In the current review, the limitations of data management and recently developed strategies in this sector have been revised, together with the need for new technologies and their use in the evolution of the precision livestock farming concept. The importance of traditional...

INTRODUCTION The selection of animals for improved production traits has been, for a long time, the major driver of pig breeding (1, 2). More recently, because of the increasing concern with environment, new selection criteria have been explored, such as nitrogen (N) or phosphorus (P) excretion, which are related to both feed efficiency and environmental impact (3). Residual feed intake (RFI) was also proposed as a possible selection criterion to simultaneously improve feed...
