Several technologies have been tested to reduce enteric methanogenesis, but very few have been successfully used in practical conditions for livestock. Furthermore, the consequences of reducing rumen methane production on animal performance and milk quality are poorly understood. The aim of this work was to investigate the effect of feeding bromochloromethane (BCM), a halogenated aliphatic hydrocarbon with potential antimethanogenic activity, to dairy goats on rumen archaea community by pyrosequencing. Sixteen goats giving birth two kids were used. Eight goats were treated (Pos) with bromochloromethane after giving birth over the lactation period. The other 8 goats were not treated (Neg). Rumen samples from goats were collected from both experimental groups at weaning (8 weeks). Nutritional intervention with BCM affected the structure of methanogenic archaea species. Relative abundance of the family Methanobacteriaceae was modified with BCM. The genus Methanobrevibacter slightly increased and Methanosphaera decreased in Pos compared to Neg. Further research is needed in this field.
