Extensive Livestock Feeding and Grazing
A.Y. 2024/2025
Learning objectives
The course aims to provide the student principles of livestock nutrition in free range-based farming systems and of grazing management. In this respect, the course provides insights into the evaluation of nutritive characteristics of different feed and pastures, monitoring of feeding behaviour,, and guidelines for feed supplementation. Moreover, the course provides basic information on grazing methods and techniques to maintain and restore productive grassland.
Expected learning outcomes
Knowledge and understanding: the student, at the end of the course, will have to demonstrate knowledge and understanding of the principles of nutrition management in free range and pasture-based farming systems and management and maintenance of grazing resources. Applying knowledge and understanding : the student will have to demonstrate ability to apply knowledge of animal nutrition and maintenance of grazing resources management to simple simulated cases. Making judgments: the student will have to demonstrate the ability to critically present the information acquired, by means of discussions in class and specific seminars. Communication: the student is expected to use scientifically appropriate language, in particular terminology referring to animal nutrition and grazing management. The practical activities and seminars are intended to stimulate the ability to use specific terminology and the ability to discuss scientifically with peers. Lifelong learning skills: the student must gain the ability to use acquired knowledge to interpret new scenarios , for instance searching scientific databases and critically organising new information.

Teaching methods
Lectures (40 hours, 5 CFU). Practical activities (16 hours, 1 CFU). Lectures and seminars will be presented with the support of Power Point slides.
Teaching Resources
Lecture notes on each topic will be provided online (in PDF format) prior to each class session.
Assessment methods and Criteria
The methods and criteria for assessing the student's performance are made available by the professor at the beginning of the didactic activities. The exam consists of a written final test with three open-ended questions and an optional partial ongoing test. The time given for the written test is 30 minutes. The score is expressed in thirtieths. The assessments are designed to test students' retention of core knowledge and measure their ability to apply this in different contexts. The results of the written exams will be available on Ariel. .
