The brutal winter storm dumped heavy snow on the northern part of Texas on December 26. Farmers have not yet fully assessed the damage.
"They're still trying to dig out, but at least it stopped snowing," Kirsten Voinis, a spokeswoman for the Texas Association of Dairymen, told AFP.
Texas ranchers typically let their cows graze in pastures rather keeping them locked up in barns. The storm hit too suddenly for them to get their cows inside.
Safely disposing of the carcasses will be a major challenge.

"We usually send them to rendering, but we're not sure if rendering will be able to handle a number this big," Voinis said.
"We're trying to figure out if there's wintering capacity, or if we do have to bury them. That opens up other issues... water quality and how it impacts your land."
Many of the surviving cows will also likely give less milk for months to come. They are typically milked twice a day, but the bad roads and blowing snow meant farm workers were unable to get some cows into their barns to be milked for as much as two days.
"That means the dairy cows in this region will give less milk for months to come. Less milk going to market will be felt by consumers, as well as by dairy farmers.
