Predicting 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 کاملMethane Production in Dairy Cows Impact of Feed and Rumen Microbiota
Greenhouse gas emissions from the agricultural sector represent about 14.5% of total emissions related to human activity. Approximately 40% of agricultural sector emissions derive from enteric methane (CH4) production by ruminants, due to their microbial digestion of feed. Level of CH4 production varies according to feed type, feed intake and even among individual animals raised under similar c...
متن کاملLong-term effects of feeding monensin on methane production in lactating dairy cows.
The objective of this study was to determine the long-term effects of feeding monensin on methane (CH4) production in lactating dairy cows. Twenty-four lactating Holstein dairy cows (1.46 +/- 0.17 parity; 620 +/- 5.9 kg of live weight; 92.5 +/- 2.62 d in milk) housed in a tie-stall facility were used in the study. The study was conducted as paired comparisons in a completely randomized design w...
متن کاملMethane Production in Dairy Cows Correlates with Rumen Methanogenic and Bacterial Community Structure
Methane (CH4) is produced as an end product from feed fermentation in the rumen. Yield of CH4 varies between individuals despite identical feeding conditions. To get a better understanding of factors behind the individual variation, 73 dairy cows given the same feed but differing in CH4 emissions were investigated with focus on fiber digestion, fermentation end products and bacterial and archae...
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...
