Of Mice and Mammals: The GenomicUpgrade Coming to Your Food Supply

What does genomics have to do with the meat and dairy on your plate - and why are investors increasingly treating livestock genetics as a platform play rather than an agricultural niche? The global animal genetics market is a nearly $7 billion industry growing at approximately 7 percent annually. Small gains in feed efficiency, disease resistance, and reproductive performance compound across billions of animals - making livestock genomics one of the most economically consequential, and underappreciated, applications of DNA science.

There are approximately 1 billion cattle on earth. About 700 million pigs. Roughly 25 billion chickens. Together, these animals represent the primary source of animal protein for most of the world's 8 billion people.

Improving how efficiently those animals convert feed into protein by even a few percentage points is not a niche agricultural improvement. It is a trillion-dollar lever on the global food system.

Genomics is that lever. The companies that own it occupy a position in the food supply chain that most investors have never seriously mapped.

The Market Infrastructure

The global animal genetics market was valued at approximately $6.98 billion in 2025 according to Mordor Intelligence, growing at 6.23 percent annually toward $9.44 billion by 2030. The top five suppliers collectively hold 55 to 60 percent of global revenue.

Key publicly traded companies include Genus plc (GNS:LSE), the global leader in swine and bovine genetics through its Genus PIC and Genus ABS divisions; Zoetis (ZTS:NYSE), the world's largest animal health company with significant genomic testing exposure; and Neogen Corporation (NEOG:NASDAQ), which provides DNA typing and genetic trait testing to livestock producers globally.

In April 2025, Genus achieved a landmark milestone: FDA approval for its PRRS-resistant pig - a CRISPR-edited animal engineered to resist Porcine Reproductive and Respiratory Syndrome, a disease that causes an estimated $664 million in annual losses to the U.S. swine industry alone. It was the first FDA clearance of a gene-edited pig for commercial food production in the United States - a regulatory precedent that could open the door to other gene-edited livestock traits.

What Genomic Selection Has Already Delivered

The gains from decades of systematic genomic improvement are embedded in the food most people eat every day. Modern dairy cattle produce more than three times the milk per cow than their counterparts did in 1950. Modern broiler chickens reach market weight in approximately 47 days on feed conversion ratios that would have been considered impossible a generation ago.

Genomic selection accelerated all of this. By reading an animal's DNA at weaning - before it has produced milk, offspring, or carcass weight - breeders can predict which animals will perform best as adults with far greater accuracy than traditional pedigree analysis. Generation intervals collapse. Genetic progress compounds faster.

The technology is now spreading to species and regions that have seen little systematic genetic improvement - aquaculture, tropically adapted cattle breeds, and indigenous livestock with climate resilience traits. China's National Bioeconomy Development Plan includes state-funded programs focused specifically on swine breeding, disease-resistant poultry, and aquaculture genomics.

Gene Editing Enters the Commercial Herd

Beyond genomic selection, gene editing is beginning to enter commercial livestock production. The Genus PRRS-resistant pig is the most commercially advanced U.S. example. Using CRISPR-Cas9, Genus edited a receptor that the PRRS virus uses to enter pig cells, producing animals with demonstrated high resistance to the disease.

Argentina and Japan have created regulatory pathways treating certain CRISPR edits - those that do not introduce genetic material from other species - as equivalent to conventional breeding outcomes, potentially accelerating commercial adoption in those markets ahead of the U.S.

Hornless cattle, heat-tolerant breeds, and disease-resistant shrimp are all in development. Each represents a gene editing application that eliminates a specific, measurable production loss.

The companies that own pedigree genetics at the top of the breeding pyramid sit upstream of billions of animals and one of the most fundamental challenges of the century: feeding more people from less land, with fewer environmental consequences.

Of mice and mammals - the mammals are where the money is.
