Estimation of the relative bioavailability of manganese sources for sheep.
The relative biological availability of Mn in reagent-grade (RG) Mn sources was tested using 41 Rambouillet crossbred wether lambs in a completely randomized design. Lambs were fed a basal corn-soybean meal-cottonseed hull diet (37.6 ppm Mn, DM basis) or this basal diet supplemented with 0, 1,500, 3,000 or 4,500 ppm Mn from RG MnSO4.H20 or 3,000 ppm Mn from RG MnO, MnO2 and MnCO3. Feed intake w...
متن کاملRelative Biological Availability of Manganese from Some Inorganic Sources for Chicks
An experiment was conducted to estimate the relative biological availability of manganese (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 b...
متن کاملGene expression of manganese-containing superoxide dismutase as a biomarker of manganese bioavailability for manganese sources in broilers.
The goal of this study was to determine whether Mn-containing superoxide dismutase (MnSOD) gene expression in heart tissue would reflect differences among bioavailabilities of Mn sources earlier than other indices. Broilers were divided into 5 groups and fed a Mn-unsupplemented basal diet (control) or the basal diet supplemented with 120 mg of Mn/kg as Mn sulfate or Mn methionine E (Mn Met E), ...
متن کاملUse of chemical characteristics to predict the relative bioavailability of supplemental organic manganese sources for broilers.
Twelve organic Mn sources and MnSO4 were evaluated by polarographic analysis and via solubility in buffers (pH 5 and 2) and deionized water. Fractions from solubility tests were evaluated by gel filtration chromatography for structural integrity. Organic Mn sources included five Mn methionine complexes (Mn Met A to Mn Met E), two Mn proteinates (Mn Pro A and Mn Pro B), and five Mn amino acids (...
متن کاملthe effect of nano manganese sources on performance and manganese bioavailability in broiler chickens
this study was conducted to evaluate the bioavailability of nano and micro sources of manganese in broiler chickens. two hundred and eight, 10-d-old male ross 308 broilers in a completely randomized design with 13 treatments, 4 replications and 4 chicks per replicate were studied for 35 days. during the experimental period, a basal corn-soybean meal diet containing 20 ppm mn (control treatment)...
