Nutrition

Objectives

The discipline aims to domain the knowledge in the digestive mechanisms interpretation in metabolic interrelationship of absorbed nutrients and diet formulation for major domestic animal species exploited for zootechnical purposes and the study of feeding strategies for the different production systems.

It is intended that the student to complete this course is able to equate concrete situations and to propose a practical solution to food management, which is based on the basic principles of livestock production in general and particular in Nutrition. In addition students must be familiar with the most investigated topics in Animal Nutrition.

Teaching Methodologies

The teaching methodology is based on theoretical classes (20 hours) theoretical-practical (26 hours), in the last, the student should elaborate an individual project, based on a scientific paper published last year in an International Journal of specialty, which is presented and discussed in the classroom.
