Feeding saponin-containing Yucca schidigera and Quillaja saponaria to decrease enteric methane production in dairy cows.
An experiment was conducted in vitro to determine whether the addition of saponin-containing Yucca schidigera or Quillaja saponaria reduces methane production without impairing ruminal fermentation or fiber digestion. A slightly lower dose of saponin was then fed to lactating dairy cows to evaluate effects on ruminal fermentation, methane production, total-tract nutrient digestibility, and milk...
متن کاملPredicting Methane Production in Dairy Cows
Methane is a potent greenhouse gas, to which enteric fermentation from ruminants contributes significantly. Reliable and accurate predictions of methane (CH4) production from dairy cows would be of interest to develop mitigation strategies and for national inventories. Thus, the overall aim of this thesis was to predict CH4 production in dairy cows by modelling approaches. Predicted in vivo CH4...

متن کاملDoes Dietary Mitigation of Enteric Methane Production Affect Rumen Function and Animal Productivity in Dairy Cows?
It has been suggested that the rumen microbiome and rumen function might be disrupted if methane production in the rumen is decreased. Furthermore concerns have been voiced that geography and management might influence the underlying microbial population and hence the response of the rumen to mitigation strategies. Here we report the effect of the dietary additives: linseed oil and nitrate on m...
متن کاملProduction, Management and the Environment: Environmental Quality
A total of 3 experiments (Exp), in vitro and in vivo, were conducted to investigate the effects of saponin extracts from Quillaja saponaria (QS), Yucca schidigera (YS) and Camellia sinensis (TS) on CH4 emissions from steers. The in vitro Exp was carried out to determine the effects of saponin inclusion on ruminal methanogenesis and fermentation parameters. Two doses (0.5% and 2.0% of substrate ...
