ABSTRACT
In modern farming practices, drugs are being used on a large scale. This is connected with the enormous increase and intensification of animal husbandry. In contrast to the traditional system of free-range husbandry, in which the animals were allowed to wander around wide areas of the farm in the open air to forage for food, the current intensive rearing of animals in restricted accommodation has inevitably increased the incidence and spread of diseases. Hence, there has been an increased need for using therapeutic agents.
