TriCross Dairy was cofounded by Californian brothers-in-law Tom Koolhaas and Wes Bylsma.
Their dairy facilities, which were completed in November 2017, include a 1,100 by 600-foot cross ventilated free stall barn and a 100-cow rotary parlour.
TriCross Dairy is home to 5,000 head of dairy cows.
Their ProCROSS crossbreeding system began with VikingRed bulls on Holstein cows. The resulting heifers were bred with VikingRed bulls.
“My father-in-law, Willie Bylsma, has used ProCROSS for 20 years, so we already knew the system,” Koolhaas says and continues: “When we decided to build our new dairy in South Dakota, there was no doubt that we would have ProCROSS cows”.
