Evaluation of Fe, Cu, Mn and Zn in manure of weaned pigs receiving high levels of organic or inorganic supplementation

Consulter le resumé

A 40 days experiment has been undertaken to evaluate the Fe, Cu, Mn and Zn excretion of piglets given the upper concentrations allowed by European legislation in compound feeds. 40 male and female piglets blocked at an average weight of 8.0 kg (28 days of age) received ad libitum up to 28.6 kg control or experimental diets formulated without phytase. Inorganic (sulfates and oxide) or organic sources were respectively used in control and experimental diets as a supplementation of 110, 150, 50 and 110 mg of Fe, Cu, Mn and Zn elements per kg.
