Introduction

Microbes are minute single-cell life-forms common to most habitats on Earth. Animals harbor microbes on and within their body, and these microorganisms can influence health and well-being of the animal host. Microbes can reside on the skin, in the airways, in the reproductive tracts, and in the digestive tract of mammals. The hosts have developed symbiotic relationships with these microbes in the gastrointestinal tract that can influence nutrient availability to the host and are an important part of normal function. In particular, ruminant animals have evolved to exploit a symbiotic relationship with microbes that allows the digestion of complex fibrous biomass in their rumen, a pregastric chamber of their gastrointestinal tract.

Collectively, the microbes
