Purina® CX8™ Additive Technology Unlocks Reproductive Potential in Beef Cattle
ARDEN HILLS, Minn. (Sept. 4, 2025) -- Purina Animal Nutrition, an innovative leader in animal nutrition, is driving the success of reproductive health in beef cattle through the launch of CX8™, an additive technology designed to optimize reproductive performance for beef producers utilizing advanced reproductive technologies such as artificial insemination, embryo transfer and semen collection.
Purina’s value-added solutions empower beef cattle producers and nutritionists to unlock the full genetic and productive potential of their herds through precision nutrition and expert guidance. Purina® CX8™ additive technology incorporates eight nutritional components positively impacting rumen fermentation, trace mineral and energy utilization, and oxidative stress which optimizes fertility, increases first service conception and maintains a healthy pregnancy during the gestation period.
“In research completed at the Purina Animal Nutrition Center, in a well-managed herd, improvements in first service artificial insemination protocols determined mature cows saw an increase on first conception rates while consuming CX8™ 30 days before breeding and 90 days after conception,” said Ted Perry, Director of Beef Technical Services. “With the current cattle market, this data shows the opportunity to improve reproductive performance making every minute and dollar spent count during breeding season.”
How to Use CX8™?
It is recommended to feed CX8™ 30 days before artificial insemination; embryo collection from donor cows or embryo transfer into recip females; and natural service conception protocols. Continue feeding CX8™ 90 days following initiation of breeding. For bulls, it is recommended to feed CX8™ at least 60-90 days before semen collection. For natural service breeding programs, feed CX8™ 60-90 days prior to bull turnout and continue feeding through the breeding season.
CX8™ is designed to be fed at 1 lb./head/day. It can be hand fed to cattle daily or incorporated into a total mixed ration designed to deliver 1 lb. of CX8™ daily to cattle. Cattle consuming 1 lb. of CX8™ daily will receive equivalent mineral and vitamin supplementation as they would if consuming 4 oz. daily of Purina® Wind and Rain® All Seasons 7.5 CP ProCycle mineral.
