USIMO to Showcase New Livestock Cooling Collar 'Moo-tto Cool' with Phiten Tech at Miyoshi Market on May 27

Press Release Overview Ohtsuki Co., Ltd., the developer of the livestock supply brand 'USIMO,' will host an exhibition booth at the Miyoshi Livestock Market in Hiroshima on May 27, 2026. The highlight will be the new 'Moo-tto Cool' contact-cooling neck collar, designed to combat heatstroke in calves and reduce heat stress in adult cows and horses.

The new 'Moo-tto Cool' integrates health science leader Phiten's relaxation and recovery effects into the existing cooling framework. This eco-friendly device requires no electricity; it uses water retention fibers and can be supplemented with ice or cooling packs to efficiently cool the neck's blood vessels and regulate animal body temperature.

Background and Urgency In the summer of 2023, Japan faced a record-breaking heatwave that severely impacted the livestock industry. According to the Ministry of Agriculture, Forestry, and Fisheries, 1,234 cattle died from heatstroke between July 1 and August 31, more than double the deaths recorded in the same period of 2022. While standard measures like ventilation are encouraged, they are often insufficient against extreme heat, creating a dire need for direct cooling solutions.

USIMO has been developing cooling products since 2020. Based on feedback from farmers—such as 'calves are especially vulnerable' and 'livestock failing to trade due to poor condition at market'—the brand continues its nationwide caravan to test and improve its products directly on farms from Hokkaido to Okinawa.
