However, "this past winter presented farmers with some of the most challenging weather conditions faced in decades. The prolonged, extreme cold temperatures presented unprecedented demands on normal operations," Tuls said. "In spite of these difficult circumstances, this video shows our workers handling animals in a way that indicates they were attentive to their needs and following proper guidelines."

He said the company is having the Summit Calf Ranch operations reviewed by outside experts and will provide additional training and improve protocols if necessary "to ensure that our staff continues to provide the highest animal care standards in the industry."

According to Animal Equality, Tuls is a major supplier to Bel Brands, producer of Babybel and Laughing Cow dairy products.

The group in its news release encouraged Bel to adopt "meaningful animal welfare standards" for cows and calves.

In a statement, Bel Brands' U.S. Milk Purchasing Manager, Brian Zook, said the company does not do business with Summit Calf Ranch and received only 0.2% of its U.S. milk supply from Tuls Dairies in the past 12 months.
