Major advances in analytical techniques and genomics have transformed our understanding of rumen microbiology. This understanding is of critical importance to livestock production since rumen function affects nutritional efficiency, emissions from ruminants (such as methane and nitrous oxide) as well as animal health. This collection reviews what we know about rumen microbiota and the role of nutritional strategies in optimising their function for more sustainable livestock production.
Part 1 summarises advances in understanding colonisation by rumen microbiota as well as advanced methods for analysing the rumen microbiome. Part 2 reviews recent research on the role of different types of rumen microbiota such as archaea, anaerobic fungi, viruses and the rumen wall microbial community. Part 3 discusses the way the rumen processes nutrients such as fibre and protein as well as outputs such as energy, lipids and methane emissions. Part 4 explores nutritional strategies to optimise rumen function, including the role of pasture, silage, cereal feed, plant secondary compounds and probiotics.
- Reviews advances in understanding the role of different types of rumen microbiota such as archea, anaerobic fungi, viruses and the rumen wall microbial community
- Covers both the way the rumen processes fibre and protein and factors affecting outputs such as energy (affecting animal health), lipids (affecting meat and milk quality) and methane emissions (affecting environmental impact)
- Comprehensive review of the range of nutritional strategies to optimise rumen function such as the role of pasture, silage, cereal feed, plant secondary compounds and probiotics.
What others are saying...
"An up-to-date reference text on the ruminal microbiota and its function is long overdue. The proposed volume will fill the gap admirably."
