Learning objectives
To provide imformation on food producing animal feeding, the final goal is to teach how to improve animal production efficiency through animal nutrition
Expected learning outcomes
At the end of the course the student will have to know the basics of animal nutrition, the characteristics of the feed used, the methods of treating feed in the feed mills and the nutritional interventions aimed at reducing the environmental impact of the farms. He must have acquired the ability to evaluate the nutritional characteristics of diets according to the physiology of the digestion of food producing animals, the composition of food and the technological treatments adopted.
