Educational objectives

D1 - KNOWLEDGE AND UNDERSTANDING

The main knowledge acquired will be:

principles of animal nutrition in farm animal species; knowledge of the classification and function of carbohydrates, proteins, lipids, minerals and vitamins. Knowledge of classification, chemical composition, physical and nutritional characteristics of forages, concentrates and by-product feeds. Knowledge of the anti-nutritional factors and how they can affect feed nutritive value; assessment of forage quality; knowledge of handling, processing and use of feedstuffs

D2 - APPLYING KNOWLEDGE AND UNDERSTANDING

At the end of the training the student must:

1) know how to recognize and evaluate the raw materials used for diets of farm animals and pets;
2) to know how to evaluate the chemical nutritional and health quality of diets administered to farm animals and pets;
3) know how to evaluate the correlation between the type of diet and the physiological and health state of the animals.

D3 – MAKING JUDGMENT
At the end of the training the student will be able to:
- assess the quality of raw materials and feeds destined for livestock and pets;
- assess the correctness of a diet administered to livestock and pets, also in relation to physiological status and health status;

D4 – COMMUNICATION
At the end of the training the student will be able to:

- know how to organize, prepare and exhibit, to an audience composed of
people of the same level of preparation, a presentation on a group of raw materials or on a diet intended for farm animals or pets with their own
assessments supported by appropriate arguments;

- support a cross-examination with people of both equal preparation and
experts in different subjects, of a regulatory and scientific nature,
procedural and / or technological;

- demonstrate language properties, including multidisciplinary ones, both in written and oral form, as well as the ability to use appropriate terminology for a correct approach to the profession, which is also important for job interviews.

D5 - LIFELONG LEARNING SKILLS
At the end of the training the student will be able to:
- consult and understand scientific texts, even innovative ones,
bibliographic updates, normative dictations, so as to employ them
in contexts not only usual for the profession, including research, but
also originals;
- possess a command of the subject such as to guarantee an acceptable basis to continue updating
throughout his life, through training
continuous continuous (ECM).

Prerequisites

For the exemption of Animal Nutrition and Feeding I the preparatory courses relating to the entire course of Animal Nutrition and Feeding are request:

Veterinary general and special physiology (all modules),

Agronomy and economics,

Special zootechnics and biotechnologies applied to zootechnical productions.
The above mentioned exams must already be passed and reported on “sol” before proceed with the online registration for the exemption.

Teaching methods

The teaching methods used are those set out below:
a) theoretical lessons on all topics of the course;
b) Exercises in the classroom for knowledge of foods and their use in the various species. During the exercises, the teacher remains available to the students, divided into working groups of 2-3 people, for clarification during the recognition of the foods. The results are discussed with the entire class. The exercises are conducted in four rounds (the students are divided into 4 groups, 2 h per each group), to enable better learning.
c) field exercises at farms of dairy cattle - beef cattle - sheep, horses, pigs, poultry and at the University Animal Husbandry (pigs - sheep - cattle) to enable knowledge of the production, storage and storage of raw materials and complete and complementary feed. During the visits, it is encouraged to compare with staff working at the company.
d) Field activities at private farms (dairy cattle - beef cattle - sheep) and at the “Azienda Zootecnica Didattica” of the University (pigs - sheep - cattle).
