Journal ArticleDOI
Investigation of chromium, cerium and cobalt as markers in digesta. Rate of passage studies
TL;DR: A new liquid marker, cobalt-ethylenediamine tetraacetic acid (EDTA), and two solid markers, chromium (Cr) and cerium (Ce) mordanted plant cell walls, were investigated and Co- EDTA was found to be comparable to Cr-EDTA.
Journal ArticleDOI
The measurement of liquid and solid digesta retention in ruminants, equines and rabbits given timothy (Phleum pratense) hay.
TL;DR: Solids retention decreased with decreasing body-weight in the ruminants, but sheep had longer retention times than goats of similar size, and Equines exhibited large individual variation in retention of the liquid or solid markers, seemingly unrelated to size.
Journal ArticleDOI
Comparative digestion of timothy ( Phleum pratense ) fibre by ruminants, equines and rabbits
Peter Udén,Peter J. Van Soest +1 more
TL;DR: Increasing body-weight was associated with higher digestibility in ruminants, but no such trends were seen in the non-ruminants, and no appreciable digestion of the generated microbes by the host was suggested by the values obtained for the equines.
Journal ArticleDOI
Investigations of the In Situ Bag Technique and a Comparison of the Fermentation in Heifers, Sheep, Ponies and Rabbits
Peter Udén,Peter J. Van Soest +1 more
TL;DR: Fiber fermentation using the in situ bag technique was studied in a hay-fed cow and showed that plant fiber containing approximately 50% lignin and 2.9% N entered even 20-micron pores, that rumen contractions increased fiber disappearance and that obstructing liquid exchange limited fermentation.
