California startup Circularity Fuels has completed a six-month pilot converting raw manure biogas from a 5,000-head dairy farm near Madera into certified sustainable aviation fuel – the first demonstration of its kind.
The modular system achieved 98% methane conversion and 90% carbon dioxide conversion, producing fuel that met ASTM certification for blending with conventional jet fuel at up to 50%. The company says its approach bypasses costly gas-cleaning infrastructure, achieving capital costs roughly one-fifth of other facilities, and plans to break ground on commercial-scale installations in 2027.

A part of the Merck Animal Health portfolio, SenseHub® Dairy is a full-solution monitoring ecosystem that continuously analyzes calf and cow behavior and performance data. Learn more here.
A new startup has developed a non-invasive breath analysis device weighing under 15 pounds that can be operated cowside to detect cattle diseases without waiting days for lab results from nasal swabs.
The prototype reads the chemical makeup of breath and compares it against an AI database of more than 10,000 validated breath images from healthy and infected animals. The company (EnSenSys) is calibrating its device for up to 12 cattle diseases, with potential applications for examining fresh cows for illness, checking calves for respiratory illness on dairies and screening cattle during routine chute work.

eVerse.AI is helping smallholder dairy farmers monitor cattle health using smart collars that provide early disease prediction, GPS tracking for grazing animals and heat detection. The company’s Connected Cow app stores each animal’s health history and medical records, while CowGPT — an AI assistant available through WhatsApp in multiple languages — gives farmers instant access to advice.
The startup is also exploring carbon finance programs that would let smallholder farmers earn additional income through verified emissions reductions from their herd.

Vacavision, founded at Babson College by Colombian entrepreneur Bryan Ramirez Galindo, mounts cameras in barns and uses artificial intelligence to track cow movements and behavior for signs of fertility, illness, stress and calving. The approach offers a non-invasive alternative to on-animal sensors. The company has pilots running in three states and launched its first paid pilot this month after joining an agricultural accelerator in Alabama.
“Every cow tells you something long before a human notices,” Ramirez Galindo says. “We just make sure nobody’s listening too late.”

Russian neurotech company Neiry claims to have surgically implanted neural devices in five dairy cows that use neuromodulation to maintain feed intake and milk output. The system automatically adjusts stimulation when a cow’s appetite decreases, potentially overcoming the natural drop in feed consumption that reduces production. The company says the electronic unit attaches to the back of the animal’s head with electrodes reaching brain regions responsible for appetite and reproduction. The technology has not been independently verified, and neuroethicists have raised significant animal welfare concerns about controlling animals’ minds.

Projected profitability for the next 12 months for two dairy herd sizes DECLINED in recent profit projections from ZISK.
ZISK is a profit projection smartphone app that tracks individual dairy farm profitability based on current CME board prices. Projections for a 1,000-cow dairy producing an average of 80 pounds of milk per cow and a 2,500-cow dairy producing an average of 85 pounds of milk per cow are provided.
12-month dairy farm profit projections (as of July 3, 2026):
1,000-cow dairy = $238,500 (DOWN about $155,690 in the last two months)
2,500-cow dairy = $1.318 million (DOWN about $422,000 in the last two months)
