Different methods of preparing rumen and caecum content from reindeer (Rangifer tarandus tarandus) for the analyses of minerals

Different methods were used for preparation of samples of rumen and caecum content from reindeer. The mineral contents of the samples were compared. Rumen and caecum samples from three reindeer were centrifuged at sampling and the fluid was stored frozen. Further preparation of these samples caused...
