[Characterization of straw pellets. 4. Degradation of 15N-labeled straw pellets in the digestive tract of the sheep]

[Feed value of straw materials in the in vitro system. 3. Measurement of in vitro protein synthesis on the basis of the incorporation of 15N in the TCA-precipitable fraction of rumen fluid]

For several reasons the utilisation of 15N for the characterisation of the microbial protein synthesis in the artificial rumen seems to be, in contrast to the incorporation of 35S, not very suitable in order to characterise the feed value of straw materials.

A selected bibliography of biomedical and environmental applications of stable isotopes. III--15N 1971-1976

A compilation of selected references of the use of 15N in biochemical, pharmacological, clinical and environmental applications for the period 1971--1976 is presented. Author and subject indices have been compiled to enable the reader to make further use of this information.
