Dan Grum (Purina Animal Nutrition) Tail docking of pigs is banned in many countries based on animal welfare concerns. An unintended consequence of the ban can result in the loss of tail integrity from bacterial pathogens causing inflammation, lesions, and necrosis which impacts pig welfare and results in significant monetary losses. Tail docking is used in many countries as a preventive measure; however, in these countries, an intact tail is a...

Diana Ayala (Purina Animal Nutrition) Post-weaning diarrhea (PWD) is a serious health and welfare problem for the global swine industry. PWD is a multifactorial condition occurring the first 10–14 d after weaning; it is generally associated with the proliferation of pathogenic Escherichia coli groups, specifically enterotoxigenic E. coli (ETEC); however, PWD is also associated with several viral infections. Antibiotics are commonly used as a control...

Caroline González-Vega (Cargill) This study was conducted to investigate the effects of medium-chain fatty acid blend (MCFA) and a phytogenic feed additive (Fresta® Protect, Delacon, Austria) on growth performance and gut health of Escherichia coli (ETEC)-challenged pigs. A total of 200 weaned pigs with initial body weight of 5.52 ± 0.17 kg were allotted to 40 pens (5 pigs/pen) blocked by BW and randomly assigned to 5 treatments: (1)...

Nick Gallina (Purdue University) Background: Intestinal barrier dysfunction, inflammation, and elevated expression of heat shock protein 60 (Hsp60) are features of the dysbiotic gut. Probiotics can alleviate inflammation but are ineffective due to poor adhesion and adaptation to the inflamed bowel. We hypothesize that enhancing probiotic adhesion to intestinal cells may augment the immunomodulatory response, mucosal healing, and tight...

Nick Gallina (Purdue University) Background: Enterotoxigenic Escherichia coli (ETEC) strains are the primary perpetrators of colibacillosis in piglets, resulting in mortality and agribusiness economic woes. ETEC expressing fimbrial antigens, F4 and F18, are the predominant contributors to colibacillosis. F4 is most prevalent in neonatal diarrhea. F18 is more common in post-weaning colibacillosis. Intestinal epithelial interaction and...

Brian Aldridge (University of Illinois) Biological health is a complex topic of discussion and is often misunderstood as existing as a binary state in terms of the presence or absence of disease. In many ways, it is useful to explain health at a population or system level as the existence of individuals in 1 of 3 states: those in a healthy condition, those with a prediseased status, and those in a diseased state. At a systems level, it is useful to...

Yihang Li (University of Delaware) Developmental plasticity during the prenatal and early postnatal periods allows animals to adapt quickly to their environment and efficiently construct organ systems crucial for survival. These adaptations, which may be irreversible later in life, can lead animals to develop beneficial survival strategies or predispose them to chronic diseases. The gastrointestinal (GI) tract is a highly adaptive organ, contending...

Young Dal Jang (University of Wisconsin–River Falls) This study was conducted to demonstrate the effects of second iron injection before weaning and iron levels in nursery diets on growth performance, hematological parameters, and fecal microbiome of pigs. A total of 70 newborn pigs from 7 sows were allotted to 4 treatments within litter, housed in farrowing crate without creep feed, and received the first dose (200 mg iron) at 2 to 3 d of age....

1. Introduction Artificial insemination (AI) in modern pig reproduction requires liquid-stored extended-semen. Extenders provide sperm with nutrients to maintain metabolic processes (1), prevent cold shock (2), control osmotic pressure and pH (3), and antibiotics present in extender inhibit bacterial growth (4). Despite the substantial improvements made on extender formulations in recent years, the quality of stored sperm decreases over time primarily due to the increased...

Introduction Some authors understand antimicrobial resistance (AMR) as an imminent “tragedy of the commons” (1), of anthropogenic nature and analogous to climate change in terms of its challenges (1–3). Although the resistance process is a natural defense mechanism of bacteria, it can be intensified by the misuse of antibiotics both in humans and animals. Inappropriate use of antibiotics (AMU) in human health is a powerful inducer of AMR. However, about 73% of the...

Mycotoxins are toxic compounds produced by certain types of fungi that can contaminate feed and feed ingredients with detrimental effects on pig performance. Effects of mycotoxins on swine include reduced feed intake, altered nutrient utilization, impaired growth performance, immune system suppression, reproductive issues, and organ damage. Mycotoxins can cause a decrease in feed intake. Affected animals may show reduced appetite, leading to lower nutrient intake and slower growth...

Safglucan® – Mitigating the negative impact of Lawsonia intracellularis on pig performance and intestinal wellbeing. Phileo by Lesaffre has shown that feeding its yeast (1.3)(1.6) beta-glucan, Safglucan®, can help pigs cope better with the negative effect of enteric disorders caused by Lawsonia intracellularis. This is a new (patent pending) application for Safglucan® to help the pork industry achieve profitable production while also reducing antimicrobial...

INTRODUCTION Livestock monogastric species, including swine and poultry, are the main sources of meat; therefore, they are, at the same time, the main livestock species reared under intensive conditions (Eurostat, 2022). The pressure to increasingly optimize breeding resulted in antimicrobials often being used for both prophylactic and metaphylactic purposes to counteract the diseases of these animals or as growth promoters. It is currently commonly recognized that the misuse of...
