PRRS-Resistant Pig Program by Genus PLC: status and timeline

PRRS-Resistant Pig Program

Gene-edited PRRS-resistant pig approved in U.S., Canada, and four Latin American countries. PRRS is swine's costliest disease; resistant genetics would prevent major mortality and production loss.

Current obstacles

Regulatory approval for food from PRRS pigsBreeding animals approved in U.S. and Canada; pork meat approval awaits in some key markets.
Market adoption and pricingFarmers must pay for PRRS genetics. ROI and market acceptance unclear; retail premium unknown.

Physics limits

Resistance may not cover all PRRS strainsThe edited pig is resistant to the virus variants tested. Other strains or future viral mutations could partially or fully escape the resistance, though this is unlikely.
Single-gene resistance can be overcomeOver many infection cycles, viruses sometimes evolve to bypass single-gene defenses. Genus may need to stack multiple resistance genes or combine with other breeding strategies.

How it works

3 parts

Gene Editing

Targeted DNA modification for PRRS resistance

Gene editing creates a mutation that blocks PRRS virus entry. Mimics natural resistance found in some animals.

Breeding & Distribution

Elite boars, females, semen to farms

Genus breeds PRRS-resistant boars and females, selling semen and piglets so farms breed resistant offspring.

PRRS Protection

Immunity prevents swine's costliest disease

PRRS causes reproductive failure and respiratory illness. Resistant pigs avoid mortality, treatment, and lost output.
