INTRODUCTION Mycotoxins are secondary metabolic products of fungi with toxigenic effects in other living species. Worldwide, about 88% of animal feed and feedstuffs are contaminated with at least one mycotoxin [1]. Fusarium toxins are the most prevalent, where deoxynivalenol ranks at first with 64% of occurrence, followed by fumonisins and zearalenone [1]. In pigs chronically fed deoxynivalenol contaminated diets, it is observed increased expression of interleukin 8 and...

What are consequences of the ban for farmers? The ban will increase the risk for the development of digestive problems in piglets after weaning. Most pig producers already have very high standards of hygiene and management practices, but the ZnO ban means we have to even better take care of these things. This could mean that we have to re-evaluate for example the state of the weaning facilities. Are the feeders and drinkers still ok? It is also important to have the right pig...

1. Introduction The microbiota plays important roles on the maturation of the intestine and immune system and consequently affects the health of the host [1,2]. The physicochemical properties and the direct interaction with intestinal cells lead to a distinguishable composition of the microbiota along the gastrointestinal tract [3–5]. The microbiota in the intestinal lumen is more related to dietary compounds, whereas the mucosa-associated microbiota directly interacts...

Issues involving the environment, social and corporate governance in swine production will be highlighted at the event
With the theme "Pork production from an Agribusiness perspective", the sixth session of the IPVS2022 Pre-Congress, which takes place on June 21st at the RioCentro, Rio de Janeiro (RJ), will address issues involving environmental, social and corporate governance (ESG), as a link between science and the demands of the global...

How important is the pig’s microbiome? The intestinal microbiota plays a major role in the development of the immune system, the stability of the digestive process and intestinal health. All of these are prerequisites for the overall performance and animal health. The microbiome should therefore be nurtured. The microbiome is a highly dynamic process and changes drastically in its composition from the day the piglet is born. Right...

How does the ban change the way we look at feed formulation? Zinc oxide (ZnO) has often covered up mistakes within our piglet feed formulations. When we remove ZnO, excesses or imbalances in our formulation become visually obvious in the form of higher incidences of diarrhoea, variability within a batch, secondary diseases, higher feed costs, higher cost of production, higher mortality and more. The ZnO ban forces us to reflect on some of the often-overlooked aspects of our...

Main text Porcine circovirus type 2 (PCV2) was first described in 1998 [1], and since then, it has become one of the most important pig pathogens, contributing to considerable economic losses by a syndrome called porcine circovirus disease (PCVD). The virus has demonstrated the highest evolution rate among similar DNA viruses, resulting in genetic shifts even over the rather short period of time since its recognition [2]. Today six genotypes of PCV2 are known, PCV2a-f [3]. PCV2d...

The intestinal morphology can be compromised in pigs when exposed to heat stress (HS), partly due to increased production of reactive-oxygen species. Because methionine (Met) functions as intracellular antioxidant, requirement of Met may be increased in HS-pigs. The effect of dietary supplementation with DL-Met above requirement on performance and serum concentration (SC) of free AA in HS-pigs was evaluated. A basal wheat-soybean meal diet was formulated to meet 100% Met requirement...

INTRODUCTION Antibiotics have given significant contributions to the human food production chain during their almost 80 years of use. Such contributions include a reduced incidence of bacterial disease, improved animal health status, and an overall enhancement in production efficiency (1, 2). However, due to concerns of antimicrobial resistance and its consequences to human health, the entire food-producing industry is under pressure to remove antibiotics from animal production...

Introduction Post-weaning diarrhoea ( PWD ) is a significant enteric disease causing considerable economic losses for the pig industry. Among several etiological risk factors, enterotoxigenic Escherichia coli ( ETEC ) is considered to be a major cause, i.e. colibacillosis. The use of antibiotics at subtherapeutic concentrations was routinely used as growth promoters for several decades, but has since 1 January 2006 been banned in the European Union due to the...

Introduction There are four forms of phytic acid (inositol hexakisphosphate, InsP 6 ), which have been identified in nature, myo, neo-, scyllo- and D-chiro-, that differ in their stereochemical conformation (Fig. S1) and association with metal ions as phytates in different soils (Turner et al., 2002). Among these, myo-inositol hexakisphosphate (InsP 6 ) garners the most attention from plant scientists. It is the principal storage form of phosphorus in plants,...

What is the incentive for the EU ban? The EU ban entails the use of high levels of ZnO (known as veterinary levels), which can be defined as levels above 150 parts per million (ppm). High levels of ZnO increase the risk of heavy metal accumulation in the environment and the potential for antimicrobial resistance. We should not forget that zinc is an essential part of swine diets, at nutritional levels (below 100ppm). Zinc is needed for various enzyme to work properly and it...

Introduction: Healthy pigs carrying Streptococcus (S.) suis on their tonsils are known to be a source of S. suis transmission in pig herds. S. suis can cause severe clinical disease, especially if co-infection with other pathogens occur. As a precautionary measure in experimental infection trials with other pathogens, pigs are treated with antibiotics to eliminate as much as potentially pathogenic bacteria as possible. The effect of cefquinome...

Introduction: This abstract describes usage of antimicrobials in Finnish swine herds in 2014. Materials and Methods: In 2014 Finnish swine health program (Sikava) collected information from its system from 1282 pig herds. This data consists of 250 519 recordings from 1204 farms. Results: The most commonly administered antimicrobial was procaine benzylpenicillin. It´s active ingredient, benzylpenicillin, was used 1199 kg. The...

Introduction: Increasing antimicrobial resistance is one of the major problems concerning both veterinary medicine and human health. There are but few reports on antimicrobial susceptibility of C. perfringens from pigs. The aim of this study was to evaluate the susceptibility of porcine isolates of C. perfringens to antimicrobial agents commonly used in swine diseases therapy. Materials and Methods: A total of 159 C. perfringens...

Introduction: The objective of this study was to evaluate the effect of providing a special feed preparation with a new feed additive based on probiotics to newborn piglets in the first day of life, on their performance during the lactation period. Oral administration of porcine lactic acid lactic bacteria in the first hours of life permits an early colonization of the intestine by beneficial microorganisms that can hinder or prevent a later colonization by pathogens. An...

Introduction: Brachyspira pilosicoli is the etiologic agent of porcine colonic spirochetosis, a diarrheal disease in growing pigs. Colitis associated with Brachyspira pilosicoli is less severe than swine dysentery caused by Brachyspira hyodysenteriae , however, antimicrobial therapy is needed on some farms to treat diarrhea in weaners and in young finishing pigs. According to principles of prudent use of antimicrobials, only effective drugs should be...

Introduction: Brachyspira hyodysenteriae is the primary etiologic agent of Swine Dysentery. The disease causes severe mucohaemorrhagic diarrhoea, and thereby severe economic losses to swine production. This study aimed to evaluate the genetic diversity, epidemiology and phylogeny among Brazilian isolates of B. hyodysenteriae obtained from outbreaks in 1990s and from 2011 to 2015. Materials and Methods: Forty-eight Brazilian isolates of...

Introduction: Outbreaks of bloody diarrhea in swine herds in the late 2000s signaled the re-emergence of swine dysentery in the U.S. Diagnostic investigations confirmed the emergence of a novel pathogen “ Brachyspira hampsonii ” with two distinct genetic groups circulating in U.S. swine. It has since been detected in swine and migratory birds in North America and Europe. Objective: The aim of this study was to develop and implement a...
