Give students the knowledge of the fundamental principles of Animal Nutrition.
At the end of this course students should be able to:
1) Know the analytical methodologies for the determination of feeds constituents that provide nutrients to the animals;
2) Describe and quantify the supply and use of nutrients by animals, distinguishing among various animal species;
3) Know the basics of mineral and vitamin feeding;
4) Quantify the animals' nutritional needs for different purposes;
5) Know the factors affecting the voluntary intake of ruminant and non-ruminant animals and methods to estimate it;
6) Know the particularities of the nutrition and feeding fish, dogs and cats.
