ANIMAL MANAGEMENT
Combat lameness before it hits your pocket When there’s lameness in a dairy herd the impact on animal welfare, productivity and economic return can be crippling. Studies in New Zealand suggest that on average, 26 percent of cows in large herds have some form of lameness in a year. Lameness is estimated to cost $400$500 per cow per season, which can really add up. A 400-cow dairy farm with 10 percent of cows lame in a season would cost the farm $20,000. On a 1000-cow farm, direct and indirect costs could be more than $100,000 at average lameness rates. Given this, prevention, early identification and treatment can not only improve animal health and well-being but greatly benefit your business by reducing the cost of lameness. Spring and mating are when most lameness occurs in our dairy herds so now is the time to be thinking about your hoofcare management programme. Prevention How you manage your herd helps protect against lameness. Cows should walk at their own pace through welldesigned races. Nutrition also plays a part in hoof health, as does using hoof mats or foot baths at the entrance to the dairy shed to apply key minerals. Hoof claws should be trimmed regularly and before they can cause any problems. Treatment The best way to aid recovery will depend on the injury itself and the time the cow will take to recover. In all cases, remove pressure from the affected claw by applying a block or shoe to the healthy claw.

Where recovery will take 4 weeks or more and require sidewall support, use a low-profile shoe such as Hoofers ($33 per cow), applied to the healthy claw, to reduce the impact on the foot.
