Relative biological availability of managanese from some inorganic source for chicks [electronic resouce].

Includes references.

An experiment was conducted to estimate the relative biological availability ofmanganese (Mn) .from some inorganic sources compared with that from reagent grade Mn sulfate. Three hundred developed local strain "Golden Montazah" male chicks 4 weeks old were used. They were randomly distributed into 10 groups (3 replicates / group) (10 male chicks / replicate) according to the average replicate body weight. Chicks were fed J0 experimental diets: the basal diet (without supplemental Mn) and 9 dietary treatments consisted of 3 supplemental Mn levels (100, 200 or 300 mg Mn/Kg basal diet) provided .from each of three Mn sources: Mn sulfate, Mn oxide or Mn chloride. The experiment extended J2 weeks in 3 intervals of4 weeks each. At the end of each 4 weeks interval, parameters ofgrowth performance were calculated. At the end of the experiment, manganese concentration in tibia bones and livers were determined.
