Magnesium absorption in sheep infused with potassium in different parts of the digestive tract
Two metabolism trials were conducted with 12 crossbred wether lambs, each surgically prepared with a rumen catheter, and abomasal and ileal cannulae to study the effect of K infusion in the different sites on site of absorption and flow of minerals. The treatments consisted of the infusion of 33.6, …

CHARACTERIZATION OF PROTEIN SOURCES AND THEIR EFFECTS ON BROILER PERFORMANCE, DIGESTIVE TRACT MORPHOLOGY AND CAECAL FERMENTATION METABOLITES
… evaluate their effects on broiler performance, digestive tract morphology and caecal fermentation. Understanding the digestion kinetics of high protein ingredients is an important step in elucidating the impact protein sources have on poultry performance and health. An in vitro assay was used to …

COMMUNITY STRUCTURES OF GUT MICROBIOME UNDER DIFFERENT DIETS IN ANGUS BEEF CATTLE
The microbiota of animals’ digestive tract plays important roles in health, nutrient utilization, and performance. For ruminants, the digestive tract, including rumen and other gastro-intestinal regions, hosts a unique and diverse microbiome that aids feed fermentation, digestion, and absorption. …

Digestive metabolism of glucosinolates: a novel approach using urinary markers for estimating the release of glucosinolate breakdown products in the gastro-intestinal tract of mammals.
… of the production of isothiocyanates in the digestive tract of monogastric animals has been achieved. Initially, a range of isothiocyanates were administered to rats and their excretion as mercapturic acids was quantified. Relative recovery of different isothiocyanates was found to be …

Consuming Brazil: Afro Brazilian Religion as a Base for Actor Training
… culture by another; and, more specifically, the digestive tract. The anthropophagy movement in Brazil framed the country's thought throughout much of the 20th century; the digestive tract is a closer examination of the consuming process that epitomizes this system of actor training.

Pseudoalteromonas sp. strain C4 as a probiotic for farmed South African abalone, Haliotis midae
… of bacterial strains were isolated from the digestive tract of Haliotis midae that are capable of degrading a wide variety of different polysaccharides (Erasmus, 1996). Strain C4 was selected for further investigation as a result of its ability to degrade alginate since H. midae is …

Early liver formation in zebrafish: a molecular and morphological approach
The digestive tract and its accessory organs - liver, pancreas, and the inner lining of the swim bladder - are derived from the endodermal germ layer. In zebrafish the digestive system starts out as a rod at the embryonic midline, which subsequently becomes patterned and outgrowth of its associated …
