A microbiome is described as a population of bacteria, fungi, protists and viruses that inhabit a specific environment. Animals, including humans, are composed of many microbiomes featuring trillions of microbes. There are different microbiomes found throughout the animal digestive tract, each with important roles in animal digestion, feed conversion, overall health. Dr. Mallory Embree is the co-founder and CSO of Native Microbials. Her company has explored relationships between microbial populations and important animal production and health metrics. They have devised custom mixtures of bacteria and fungi to supplement the diet, with positive results from cattle and chickens, and companion animals like dogs. Their pipeline features multiple products that specifically target aspects of animal husbandry. Their results verify that adjustment of the microbiome can have positive effects on animals, farmer profit, and even enhanced environmental sustainability.
