Keep animals’ sheds clean. There should not be any holes/cracks in the walls or roofs of the sheds, where these external parasites can hide or lay eggs. Spread limestone powder in sheds from time to time. Spray sheds with insecticides after removing the animals from their sheds. In case of ticks, get it treated by a veterinary doctor. Protect chopped fodder from dust and dirt and give the animals clean feed. De- worm animals regularly. Give a variety of de-worming medicines so that the worms cannot build immunity against any medicine. Whitewash the water troughs of the animals with limestone powder for protection against microbes.
