Invited review: Novel methods and perspectives for modulating the rumen microbiome through selective breeding as a means to improve complex traits: Implications for methane emissions in cattle

The rumen microbiome is responsible for methane emission in ruminants. study of microbes the has attracted great interest last decade. High-throughput sequencing technologies have been key expanding knowledge microorganisms that populate through metagenomic studies. There substantial evidence composition microbiota influenced by host genotype. Therefore, modulation poses an important tool breeding lower emissions large and small main challenges studies are addressed some solutions proposed when available, including incorporation information into statistical models regularly used animal breeding. To incorporate programs, particularities must be considered, from sampling to inclusion selection indices. latest advances this area discussed review.
