Extract

Cooperia punctata is the most prevalent parasitic intestinal nematode in Brazil and its site of fixation is duodenum and jejunum that are also the sites of greatest dietary phosphorus (P) absorption. Studies of phosphorus metabolism often involves balance trials and use of isotopes. When combined with mathematical modeling, calculation of flows between several pools becomes a possibility. The objective of the study on calves employing isotope and balance techniques was to apply and compare two models of P metabolism for resolving data generated by these techniques.
