Hello there,
Narasin is an ionophore used in animal production that can enhance weight gain and feed efficiency in growing-finishing swine by modifying hindgut fermentation. In this episode, I talked to Dr. Michael Shields about his research on a meta-regression analysis that was conducted to evaluate the effects of narasin inclusion in growing-finishing pig diets to predict average daily gain and feed efficiency. Dr. Shields enlightens us on the benefits of narasin supplementation in swine di...
Hello there,
Manganese (Mn), a vital trace mineral, supports metabolism and bone structure, functions as a component of several enzymes, and is involved in carbohydrate, lipid, and protein metabolism. In this episode, my conversation with Hilario Cordoba unveils his research on the effects of manganese in growth performance and carcass characteristics. Delving into Cordoba's enlightening discussion, we glimpse the challenges in defining optimal manganese use in swine nutrition.

Optimizing branched-chain amino acid (BCAA) to lysine ratios in swine diets could improve the growth, muscle development, and overall health of pigs. In this episode, I interviewed Dr. Ryan Samuel, an Assistant Professor of Monogastric Nutrition at South Dakota State University. We discuss Dr. Samuel's research on the effects of different BCAA to lysine ratios on carcass data, growth, performance, and economics. His study aimed to improve the amino acid ratios and balance in order to enhance the...
In swine nutrition, both mash and pellet feed are crucial to provide essential nutrients to pigs. However, their physical form, processing methods, and associated challenges differ. That means that deciding which form to use depends on various factors such as herd size, nutritional requirements, production goals, and available resources. In this episode, Dr. Roman Moreno discusses the challenges and differences between mash and pellet feed in swine nutrition.

When it comes to plant feed ingredients, pigs can effectively digest phosphorus (P) bound to phytate provided that phytase is supplemented. Feed phosphates can also enhance the digestibility of P, as they possess a high level of P digestibility and are devoid of phytate. Regardless of that, it is possible that phytate present in plant-based ingredients may form complexes with the P derived from feed phosphates, thereby reducing P digestibility. In this episode, I talk with Diego Lopez, M.Sc., ab...
Despite playing a significant role in the fermentation of dietary nutrients, the cecum and its effects on the metabolism and health of pigs are poorly understood. With that in mind, in this episode, Dr. Burkey discusses a study he worked on aimed at developing a cecectomized pig model in order to evaluate the cecum microbial community structure in cecectomized finisher pigs which were fed a high-fiber diet (soy hulls).

In swine, arginine participates in important functions related to the maintenance of intestinal health. However, nutritional practices for weaned pigs today may make the mistake of ignoring such crucial regulatory roles played by it regarding gut health and function. So in this episode, Dr. Jorge Perez Palencia discusses the research he has been working on that provides different levels of arginine to weaning pigs and analyzes their performance responses.
