Mustering and other cattle management operations are a significant cost for beef producers on extensive properties in northern Australia. As a result, a range of cattle handling equipment has been developed which uses animal behaviour patterns to simplify some tasks. Two "animal-powered" devices were developed to automatically apply parasite control chemicals to cattle as they passed through one-directional spear gates. Both applicators were based on wheel-driven pumps, and dispensed chemicals in proportion to the length of contact between the device and the animal's body. Application rates were within 10% of existing recommendations for animals in the most common weight range of 250-500 kg. The applicators were simple to install and remove, allowing easy transfer between sites. © 1992 Silsoe Research Institute.
