title: [Calcinogenic plants and the incubation effect of rumen fluid].
abstract: This paper describes incubation effects of rumen fluid on aqueous extracts of Trisetum flavescens, Solanum malacoxylon, Nierembergia veitchii, and Cestrum laevigatum. Investigation was performed by the rachitic chicken test, parameters determined were the serum levels of Ca, P, and alkaline phosphatase. Extracts of S. malacoxylon, and C. diurnum as well as 1,25(OH)2-VitD3-25-O-glucoside gave (without incubation) an increased activity, while with incubation a small additional effects could be observed. The extracts of T. flavescens and N. veitchii did not show any alteration with or without incubation. Comparable effects were obtained with 1,25(OH)2VitD3-1-O-glucoside, as well as 1,25(OH)2VitD3-3-O-glucoside.
