Central Valley dairy operators take steps to protect cattle as triple-digit heat persists

TULARE, Calif. (KFSN) -- Triple-digit temperatures continue across the Central Valley, prompting agriculture operations to manage the impacts of extreme heat while preparing for continued hot weather.

Christopher Greer, interim agricultural commissioner, said heat-related concerns often affect the dairy industry.

"A lot of the animals that we have to deal with when it comes to heat usually affect the dairy industry more so within my department, and just normal mortality rates in the summer months are higher," Greer said.

Veterinarian Dr. Crystal Heath said conditions such as crowding, limited shade and poor air movement can worsen the effects of heat on animals.

"So out on the farm you will see panting, open mouth breathing, salivation and drooling, decreasing germination, soot chewing, reduced feed intake," Heath said.

Lawrence Family Farms, named Tulare's 2026 Dairy of the Year, has been operating in the dairy industry for nearly 20 years. Owners Lisa and Matt Lawrence said preparations for hot weather begin months in advance.

The family said the design of its facilities helps keep barn temperatures about 10 to 15 degrees cooler during extreme heat.

"The pitch of the roof and the height of the roof are very important because heat rises to the center of the barn where there is a gap and the idea is for the heat to leave the barn through that gap," Matt Lawrence said.

Lisa Lawrence said animal welfare is a top priority during the hot summer months.

"And we try to do the best for them as well. Comfort is our number one priority for them. Comfort and nutrition," she said.

Protecting cattle during periods of extreme heat remains a major concern for dairy operators. The issue gained heightened attention during the 2017 heat wave, when thousands of cows were lost across the Central Valley.

"Everyone was impacted by that, and we remember that summer. How can we forget, it was brutal. You have to remember we are working right alongside these cows and so whatever they go through we suffer through it with them," Matt Lawrence said.

As high temperatures continue, farmers and outdoor workers are being reminded to stay hydrated. Meanwhile, the Lawrence family said it is already preparing and planning for the winter season.
