Livestock Production and Management

Recording monthly body weight of an animalLivestock farm is always considered as an economic unit, where the inputs are transformed into outputs through an interaction between natural and man-made factors. To obtain maximum production from the mithun animal, the livestock production and management section is managing the available resources of the farm judiciously to generate more output besides, managing the daily or routine activities of the farm such as health care, feeding and watering of different category of animals, fodder cultivation, cleaning in and around the animal sheds etc. The section also maintaining different data of the farm to generate first hand information of mithun animals: growth and reproductive performance of different age group of Mithun. To encourage the mithun herdsmen and to use them as draught or pack animal, the section also trained the animal for pulling the cart, ploughing the field etc.
