WHENEVER CALVES leave the farm on a truck, working with your trucker to make their job as easy as possible will help to ensure your calves are treated with care. The position of your bobby calf pick-up point and slink collection point can improve onfarm biosecurity and reduce the risk of exposure to pests, weeds and disease. Use the red, orange, green system to map out zones on your farm. Bobby calf and slink pick-up point should be in the green zone, and the bobby calf and slink truck should remain in the green zone while on farm. Bobby calf rearing facilities are in the orange zone. If you have to load out of the bobby shed then ensure as little cross over as possible between the truck and drivers and the inside of your bobby calf sheds. Ensure all slinks are covered and out of public view. Red: No-go areas for visitors, tankers, livestock trucks, for example, paddocks and heifer rearing sheds. Red zones can only be entered after carrying out visitor biosecurity procedures. Orange: Areas that are accepted to have a mix of cows, farm staff, visitors and equipment, e.g. the milking shed. Green: Areas that have unrestricted access to visitors, their vehicles, tankers and livestock trucks but restricted access by cows, e.g. the milk tanker track and access tracks to houses on the farm.
consuming milk from infected cows. Farmers buying or selling calves or milk can take simple steps to reduce the risk of spreading M.bovis and other diseases. Stock movements are the highest risk for spreading M.bovis. DairyNZ’s advice is to buy from as few sources as possible; deal directly with the source farm or via an agent. Don’t hesitate to ask questions about any M. bovis test results available for the farm, or whether the farm has been subject to M.bovis tracing by MPI. Ask about the stock trading practices of the farm and whether all stock movement records are up to date and recorded in NAIT. Ask about cow and calf health
