Effects of Molybdenum and Sulfur on Minerals in the Digestive Tract of Steers

Abstract

Gor-prraeN, L. S. ,qNo Borla, R. J. 1990 1975 Ivan and Veira 1981, 1982 (Hecker 1974) in each ofthe proximal duodenum (within 10 cm of the pyloric sphincter, but before entry of the bile duct), and in the terminal ileum (10-15 cm from the ileal-cecal valve). Cannulation of the proximal duodenum and terminal ileum divided the digestive tract into three regions: (l) the reticulo-ruminal-omasal-abomasal or stomach region; (2) the small intestine; and (3)

Copper, iron, zinc and tannin concentrations throughout the digestive tract of tropical goats and sheep fed a high‐fibre tannin‐rich diet

“…This divergence was also different for every micromineral, since the concentration profiles throughout the digestive tract differed distinctively between Cu, Zn and Fe, and species differences in these profiles were not uniform between these three microminerals. For instance, the absorption of Fe is largely dependent on animal body needs: animals of low Fe status or receiving diets deficient in Fe will absorb and retain more Fe in accordance with physiological needs (Golfman, 1988). Similarly, Cu and Zn are absorbed according to the requirements and homeostasis in ruminants, which are regulated by their dietary concentrations and the availability of other antagonists (Rehman, 2017), which primarily interfere with their bioavailability and absorption from the gut and subsequent utilization for metabolic processes (Gooneratne et al, 1989;Rehman, 2017).…”

Therefore, the overall process of microminerals absorption is regulated by their dietary concentrations, endogenous secretion and related to the animal's absolute requirement and status of the body (Golfman, 1988;Gupta, 2014).…”
