Juarez Donzele Thank you Prof. Donzele for your question. My understanding of the literature would indicate that when establishing Ca and P levels in the diet, the first step is to ensure that the STTD or available P level is above requirement. If it is close to or below requirement, then the ratio of Ca:STTD P or Ca: aP is very, very important. As P rises above requirement, then the ratio becomes ...

Introduction Calcium (Ca) and phosphorus (P) are the two most abundant minerals in the body of the pig and are required for many important physiological functions (Oster et al., 2016). The vast majority of Ca—about 99%—is not only present in skeletal tissues (Nielson, 1972), but it also fulfills other very important roles involving blood clotting, nerve impulse transmission, muscle co ...

INTRODUCTION The weaning process exposes pigs to a multitude of stressors such as dietary and environmental changes, social stress, and an unpredictable array of pathogens. The combination of these stressors typically results in reduced growth rate and feed intake as well as impaired function and integrity of the gut (Lallès et al., 2004; Pluske, 2013; Li et al., 2019). Further, the immu ...

Background  Xylose, as a major constituent of plant xylan polymers, is one of the most abundant carbohydrates on the earth, second only to glucose [1, 2]. This abundant pentose sugar, along with arabinose, makes up a majority of the hemicellulose backbone as arabinoxylan in the cell walls of cereal grains fed to pigs [3]. Cereal arabinoxylans (also known as pentosans) are composed of a linea ...

Background Indigestible markers are commonly used in animal nutrition studies to calculate digestibility coefficients, with chromic oxide, titanium dioxide, and acid insoluble ash being the most common in swine research [1]. Physiological aspects associated with gastric emptying or rate of passage are complex and affected by a variety of factors [2, 3]. Rate of passage can be affected by BW [4], ...
