Journal ArticleDOI
Effect of forage conservation method, concentrate level and propylene glycol on diet digestibility, rumen fermentation, blood metabolite concentrations and nutrient utilisation of dairy cows
TL;DR: Differences in rumen fermentation associated with the ingestion of forages conserved using different methods were sufficient to suggest an important role on subsequent nutrient utilisation.
Journal ArticleDOI
Effects of diets with increasing levels of Spirulina platensis on the performance and apparent digestibility in growing rabbits
TL;DR: The results show that the final weight, weight gain and feed efficiency did not differ significantly (P > 0.05) among the dietary treatments, but an SP inclusion level of 10% gave the highest feed intake.
Journal ArticleDOI
Manipulation of ruminal fermentation and methane production by dietary saponins and tannins from mangosteen peel and soapberry fruit
TL;DR: It was shown that the roughage-to-concentrate ratio, as well as the supplementation of SM pellets containing condensed tannins and saponins, caused changes in ruminal microorganisms and their fermentation end-products.
Journal ArticleDOI
Effects of the Ratio of Ruminal Propionate to Butyrate on Milk Yield and Blood Metabolites in Dairy Cows
Harri Miettinen,Pekka Huhtanen +1 more
TL;DR: An increase in ruminal butyrate supply at the expense of propionate adversely affected milk yield and the repartitioning of nutrients between milk components, as indicated by the increased production of long-chain milk fatty acids and increased plasma concentrations of acetate, Gly, and branched-chain AA.
Journal ArticleDOI
Studies of apparent digestibility in horses and the use of internal markers
TL;DR: In this paper, the authors compared indigestible internal markers (acid-insoluble ash (AIA) and acid detergent lignin (ADL)) and total collection techniques for apparent digestibility estimation in horses.
