Thanks to analysis of microbes in cows' stomachs, meat and milk production in young cows could improve.

New research led by the University of Edinburgh's Roslin Institute and Scotland's Rural College (SRUC) focused on microbes found in a cow's rumen — the first of its four stomachs.

The study paves the way for research to understand which types of microbe — such as bacteria — are best at helping cattle to extract energy from their food, experts say.

It also identifies enzymes that are specialized for breaking down plant material, which could help in the quest to develop new biofuels.

The rumen houses diverse strains of microorganisms, such as bacteria, archaea and fungi, which help the animal to extract energy and nutrients from its food.

The team used an advanced technique called metagenomics, which involves analyzing the genetic composition all of the microbes that exist within an organism, in this case a cow.

They studied samples of rumen gut contents from 43 cows and identified 913 diverse strains of microbes.

Most of the microbes uncovered hadn’t been seen before and may have potential uses in the biofuels and biotechnology industries.

By analysing their genetic information, the team pinpointed previously unknown enzymes that can extract energy and nutrition from plant material.

Understanding how these animals convert plant-based diets into energy will be vital for securing the future of the world's food supplies, experts say.

The research, published in the journal Nature Communications, was carried out in collaboration with experts at The Rowett Institute at the University of Aberdeen.

"The newly identified microbial species in the rumen of beef cattle will greatly improve our understanding of how the rumen microbial ecosystem works. Using breeding and nutritional interventions, we will be able to use this information to help improve cattle health and performance throughout the world,” Professor Rainer Roehe from SRUC said.
