COWS: Control of worms sustainably

Control of worms sustainably (COWS) has advised farmers to implement a management plan that includes monitoring cattle growth rates for weaned calves and grow cattle to reduce worm burdens.

Andy Forbes, COWS technical representative, said: “Weaned calves and cattle under two years of age are at the greatest risk of succumbing to worm challenges.

“Daily liveweight gain for growing cattle should average at least 0.8kg/day over the grazing season. When an animal falls below the target, or there is a loss of body condition, this may indicate worm control measures are needed to reduce the risk of the disease taking hold and growth rates being affected.

“Regular monitoring and, where possible, weighing cattle during the grazing season will help identify when animals may be in need of worming.
