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 The growth, development and functionality of the gastrointestinal tract (GIT) is a dynamic and evolving process that prepares the young pig, both before and after parturition, for its future growth, development and ultimately, survival. The perinatal development of the GIT can be divided into three phases: the prenatal phase, characterized by minimal stimulation from the GIT lumen; the neonatal phase, associated with changes caused...

It is now possible to train the first line of defence system of animals. This will not only help to be better protected against diseases, it also creates a stronger and better vaccine response. This immune training can be done with beta-glucans from yeast. What are the benefits for pigs? We are more...

By Fred Miller / University of Arkansas System Division of Agriculture FAYETTEVILLE, Ark. — Arkansas Agricultural Experiment Station scientists have developed bacterial cultivation methods to isolate different bacteria from pigs. These methods could be used to culture beneficial bacteria in swine intestinal, or gut, microbiomes that can serve as probiotics to protect or improve the health of pigs. ...

The characterization of the microbiota diversity inhabiting particular mucosal surfaces or other body sites has been an active topic of research in recent years, due to the involvement in many vital processes. In the gut, the high microbial diversity has the potential to provide metabolic activities that the host lacks. Specifically, the gut microbiota of mammals has been shown to confer health benefits to the host through the production of digestible food components, inhibition and...

Feed oxidation: What are the dangers? In pig diets, various sources of lipids are added to increase caloric density, provide essential fatty acids, improve feed palatability, improve pellet quality, and reduce dust (Keer et al., 2015). Some of the feed ingredients...

Introduction Nursery pig diets have been conventionally formulated with animal protein sources and dairy products (e.g., fish meal, plasma meal, and whey protein). However, this has resulted in a complex diet composition and high feed costs. Many attempts have therefore been made to simplify the conventional complex diet by increasing the proportion of soybean meal as a way to save on feed costs in nursery pig production. Previous studies (Skinner et...

Introduction Advances in genetics has certainly produced commercial strains of poultry and pig with greater performance (e.g. growth, reproduction) with minimal feed input. For example, over the last 5 decades, the body weight of broilers at 42 days has increased by 25-50 g per year and the feed conversion ratio to 2 kg body weight has improved 2-3 points annually (Havenstein et al., 2003; Gous, 2010; Aviagen, 2019). With the introduction of crosses in...

Introduction Although bacteria are too small to be seen without the aid of a microscope, their abundance by mass has been estimated to be 1,166 times larger than the mass of all humans. All animals contain populations of bacteria on outer and inner body surfaces such as the skin and the gastrointestinal tract, with the gastrointestinal tract being by far the most densely populated. It has been estimated that cattle, sheep, goats, pigs, chickens, ducks...
