Learning objectives
To understand that the use of machinery in livestock husbandry is necessary for the environment and for socio-economic reasons. To understand how machines work, their performances and limits while taking into account health and safety regulations. To learn how to choose machinery and installations. To learn how to plan and design structures and plants in relation to the problems of agricultural waste management. Special reference to livestock waste management in relation to environment safeguard will be done.To understand that the use of machinery in livestock husbandry is necessary for the environment and for socio-economic reasons.

To learn how to plan and design structures and plants in relation to the problems of agricultural waste management. Special reference to livestock waste management in relation to environment safeguard will be done.
Students successfully completing the program will be able to: choose and define the most suitable forage harvesting and cattle feeding mechanization chain; design and control milking plants, renewable energy supplies and implement health and safety regulations for machinery and installations. In addition they will know functional and design criteria of structures and plants for agricultural waste management and they will be able to use simulation and calculation tools to support the correct management of agricultural waste, with special focus on animal manure, for environment safeguard.Students successfully completing the program will be able to: choose and define the most suitable forage harvesting and cattle feeding mechanization chain; design and control milking plants, renewable energy supplies and implement health and safety regulations for machinery and installations.
