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.

Introduction Dairy cows are provided high allocations of grain following calving to meet high energy demands for milk production. However, increased grain consumption increases the flow of fermentable carbohydrates to the hindgut, increasing hindgut fermentation (Abdela, 2016). If excessive fermentation occurs, high osmotic pressure and a drop in pH induce inflammation and damage hindgut epithelial cells, thus increasing gut permeability and allowing...
1. Introduction Mycotoxins are harmful secondary metabolites produced by fungi that contaminate a wide range of food and feed products [1–3]. Depending on the frequency of occurrence and/or the severity of the disease that they produce, mycotoxins belonging to the aflatoxin, ochratoxin, and Fusarium toxin groups exert great impacts on animal/human health as well as on global trade [2,4]. Aflatoxin B1 (AFB1), zearalenone (ZEA), ochratoxin A (OTA), and deoxynivalenol (DON)...
Background Recently, a comprehensive review paper devoted to roles of nano-Se in livestock and fish nutrition has been published in the Nanoscale Research Letters [1]. The authors described in great detail an issue related to nano-Se production and its possible applications in animal industry and medicine. Indeed, it is well established that many molecules presented as nanoparticles have unusual behaviour due to the new properties of such particles. In fact, in most of the...
Introduction In swine industry, the weaning transition is a complex period during which the piglets have to cope with abrupt separation from their dam, mixing with other litters in a usually new environment and switch from highly digestible feed (milk) to a less digestible more complex solid feed; hence weaning is a stressful experience for the piglets involving nutritional, psychological, environmental, microbiological, and immunological stresses (Lalles 2008), which could...
Animal breeding is an old practice developed by humans for the production of dairy foods (cattle), transport (horses), rodeo or recreational events (dogs and bison for instance). The task of domestication and/or specific animal breeding at the industrial level includes controlled mating, successful reproduction of captive species and mass production of selected strains for our own consumption or pleasure. This dates back to the Neolithic period (about 7000 BC) when the men started to settle...
INTRODUCTION Pioneer colonization of intestinal microbiota has a major effect on driving the maturation and composition course of microbial communities over time (Juricova et al., 2013; Rodrigues et al., 2019; Wilson et al., 2019). Later, the cross-talk between microbiota composition and immune cells has been highly associated with the establishment of immune competence (Crhanova et al., 2011; Chung et al., 2012; Schokker et al., 2017; Duan, 2018). Germ-free mouse models have...

1. Introduction Weaning is one of the most stressful events in pig production [1]. Early weaned piglets face several nutritional and psychosocial stressors, including the transition to a solid diet and the abrupt separation of sows and piglets [2]. These events coincide with an immature immune and digestive system [3], which has consequences, such as the reduced activity of digestive enzymes, changes in intestinal morphology, and reduced nutrient digestion in the small intestine...
From Dr Ildar Nisamedtinov’s presentation at Lallemand’s International Selenium Yeast seminar (Grenaa, Denmark, 2007) Alkosel®R397 is made from a natural yeast strain, Saccharomyces cerevisiae NCYC R397, selected for its ability to incorporate large amounts of selenium into amino acids (selenomethionine in particular, selenocsyteine). To insure optimal selenium incorporation, S.c. R397 is grown in the presence of measured amounts of inorganic selenium, during a tightly controlled...
INTRODUCTION Saccharomyces boulardii as a probiotic yeast “Probiotics” were first conceptualized at the start of the 20th century by Elie Metchnikoff’s discovery of the immunological benefit of lactic acid bacteria in fermented milk. Today, lactobacilli and bifidobacteria are among the most important and widely consumed probiotics (Table 1). Species from other bacterial genera such as Escherichia, Bacillus and Enterococcus have...
The organizers of the upcoming Animal AgTech Innovation Summit spoke to Ben Holland (Director of Research at Cactus Feeders), Martin Borchert (Director Animal Health and Microbes Applied Research at Novozymes) and Alexander Segal (Vice President at Universal Stabilization Technologies) on feed and microbial solutions.

INTRODUCTION The egg industry is enjoying increased production as consumers have become more educated about the nutritive value of eggs. Eggs are relatively inexpensive per unit of protein and energy, therefore egg consumption has continued to increase in developing countries (Leeson and Summers, 2005). For several decades, antibiotics and chemotherapeutics in prophylactic doses have been used in animal feed to improve animal welfare and to obtain economic benefits in terms of...
Chr. Hansen Holding A/S has entered into an agreement with the owners of UAS Laboratories LLC (“UAS Labs”) to acquire 100% of the Wisconsin based B2B company specializing in clinically documented probiotics. The acquisition of UAS Labs will further strengthen and expand Chr. Hansen’s global microbial platform and Human Health...
In these past years, the concept of food safety has become increasingly more evident in the food production, mainly when it is related with the export of products of animal origin, which is a huge challenge to the industries to ensure food safety. The demand for healthier and more natural ingredients in food gains strength in Brazil and the world, with investment in technology and industry adhesion. The technology in the manufacture of the products is fundamental and integrates...
Top quality product development and high-level technical support goes hand-in-hand in enabling Phileo by Lesaffre to deliver valuable new yeast-based solutions to farmers across the world.

Lately we’ve been fielding lots of questions from manufacturers surrounding the use of probiotics in consumer food, companion animal and feed products, and it’s no wonder. The global demand for these “good bacteria” is growing...
