Swine gut health

Pigs are exposed to various challenges such as weaning, environmental stressors, unhealthy diet, diseases and infections during their lifetime which adversely affects the gut microbiome. The inability of the pig microbiome to return to the pre-challenge baseline may lead to dysbiosis resulting in the outbreak of diseases. Therefore, the maintenance of gut microbiome diversity, robustness and stability has been influential for optimum intestinal health after perturbations. Nowadays human and animal researches have focused on more holistic approaches to obtain a robust gut microbiota that provides protection against pathogens and improves the digestive physiology and the immune system. The swine gut microbiome is a complex and dynamic ecosystem harboring immensely diverse microbiota including bacteria, viruses, archaea, and fungi that ideally reside symbiotically in the gut of host animals. Among the microorganisms, the number of bacteria outnumbers other microorganisms. The microbiome robustness, the maintenance of diverse and functional microbiota in GIT is crucial for effective swine production. The microbiome robustness depends on the diversity of the microbiome, so it is not enough just to have the presence of a few different beneficial microbes. Accordingly, new strategies are required to manipulate the gut microbiome to prevent or revert unhealthy states caused by perturbations.

Introduction: Gastric ulcerations are a special challenge in modern pork production. Stress can be a reason but in particular the existing milieu conditions have an impact on the development of gastric lesions. The dietetic effects of fibre sources in pigs’ gastrointestinal tract are well known. In some cases fibre sources are used as material for the pigs to root and manipulate. The present study was focused on the amount ingested when fibre sources are offered and...

Introduction Globally, industrial coproducts from the dry and wet milling of cereal grains are often included in swine diets to reduce feed cost; however, they contain greater levels of non-starch polysaccharides (NSP) than their parent grain (Jaworski et al., 2015). It has been well established that pigs lack the enzymes required to digest NSP, and that increased dietary NSP can reduce nutrient and energy digestibility, impair hindgut fermentation, and increase digesta...

1. Introduction The small intestine is a highly differentiated and complex organ with many nutritional, physiological, and immunological functions [1–8]. First, the small intestine is responsible for the terminal digestion and absorption of dietary nutrients and is, therefore, essential to health, growth, development, reproduction, and sustaining life in organisms. Second, the neonatal small intestine can absorb immunoglobulins from milk before gut closure, which is...

1. Introduction Standardized ileal digestibility (SID) has become the accepted standard to measure amino acid (AA) digestibility (Stein et al., 2007a; Levesque et al., 2010). In nutrition, apparent ileal digestibility (AID) increases with dietary AA concentration while true ileal digestibility (TID) and SID are assumed to be independent of AA concentration (Stein et al., 2007a). The digestibility of SID AA in feed ingredients is important to the swine industry, and many...

INTRODUCTION “Ideal protein” means that no amino acid (AA) is to be supplied in excess of requirements as compared to any other AA in pig diet: i.e., an exact balance of AA, without deficiency or excess. As a consequence, protein retention (protein gain in relation to protein intake) is maximized and nitrogen excretion is minimized. This is possible through an adequate combination of protein concentrates and synthetic AA supplements (Leclercq, 1998). The use of the ideal...

INTRODUCTION The pig’s weaning period is possibly the most stressful time of its productive life and is the foundation of a thriving lifetime of growth performance [1]. During this critical period, weaned piglets face a variety of problems, including post-weaning diarrhea and reduced feed intake due to an immature immune system and limited enzyme secretory capacity [2], both of which are economically significant in today’s pig industry. Therefore, it is critical...

Introduction: Post-weaning complications in piglets are characterized by heightened susceptibility to infection, diarrhoea, atrophy of small intestine structure and reduction in body weight. The ban on prophylactic antibiotics and environmental concerns with usage of excessive zinc demands for identification of safer alternatives to treat post-weaning complications. Feed additives that maintain homeostasis between the intestinal epithelial layer, intestinal microbes and the...

Introduction: Diarrhoea during the first week of life is a big concern in many Danish pig herds - not least since the suspected introduction of “New Neonatal Diarrhoea Syndrome.” The study investigates pathogens and management-factors associated with these problems. Materials and Methods: A total of 107 herds including 55 Case-herds with diarrhoea during the first week of life and 52 Control-herds without diarrhoea as a herd problem filled in...

Introduction: The widespread use of antimicrobial agents in human and veterinary medicine has favoured the spread of resistance. In view of the transmission risk of highly antibiotic-resistant strains between animals and humans, controlling resistance is essential to safeguard the future efficacy of antimicrobial agents in veterinary as well as in human medicine. The ban on antibiotic growth promotors in the EU was a first step in the strategy to deal with antibiotic resistance....

Introduction On August 28, 2021, the United States Department of Agriculture (USDA) confirmed that African swine fever virus (ASFV) had been diagnosed in the Dominican Republic (https://www.aphis.usda.gov/aphis/newsroom/news/sa_by_date/sa-2021/asf-confirm). This poses a tremendous threat to the swine industry of the United States (U.S.) given the proximity to the mainland. When ASFV emerged in China, the virus was able to move rapidly and easily throughout the country due to movement...

Guanidino-acetic acid supplemented to pig feed optimises the creatine status of the cells and enhances cellular energy efficiency.  Creatine plays a central role in the cellular...

1. Introduction Traditionally, beer industry by-product (brewer’s grain) is used as a feedstuff intended for swine in the central region of Argentina. Worldwide, fungal contamination of foods and feeds, with consequent mycotoxin production, is a significant problem. Previous studies performed in Brazil determined the fungal flora as well as the presence of different mycotoxins in brewer’s grain and barley rootlets [1, 2]. Aflatoxins (AFs) are highly carcinogenic and...

Introduction In Canada, barley is rarely fed to young pigs due to its relatively high fibre content that is associated with lower energy and nutrient digestibility (Che et al., 2012). Carbohydrates that are not digested in the small intestine may be fermented in the large intestine, and so provide energy and stimulate gut health (Fouhse et al., 2017). Barley cultivars with increased fermentable carbohydrates may enhance gut health in weaned pigs (Jha et al., 2019). Intestinal...

Ewa Sujka talks about a natural biosurfactanct for monogastric diets that ensures an excellent digestibility of fats and availability of energy as it acts as a natural emulsifier. It also improves the digestibility of other nutrients in the feed and promotes the absorption of fat soluble vitamins. *Certain information associated with products, their composition and claims may be different depending on the geographical region and may not be applicable in all countries.

In order to increase the performance reproductive sow, premature weaning of piglets has become common practice, generating stress and retarding the postweaning growth of the pigs. The stress generated by separation from the mother, the abrupt change in food, the inclusion of raw vegetative material in the diet, and the poor development of the gastrointestinal tract in piglets result in a disruption of the mucosa integrity and a reduction in the digestion and absorption of nutrients at the...

In the countries with the higher levels of pig production, piglets are weaned 14 to 28 days after being born (Marion et al., 2002). As a result, piglets are lighter and the digestive system is less developed during weaning, particularly the gut. This renders these animals more susceptible to digestive problems in the post-weaning period (Reis et al., 2007). Besides its digestive functions, the gut of piglets forms a physical barrier that prevents toxic compounds and pathogens from...
