Learning outcomes of the course unit
The student must acquire knowledge for chemical and biological evaluation of feeding animals. Must have knowledge about the organizational and managerial aspects of animal feed and be able to possess the techniques for proper diet formulation. The student must show mastery of the factors that influence the digestibility and utilization of food as it should known additives and supplements according to criteria of necessity and function. Must also acquire concepts related to diet and nutritional requirements for different
domestic species in various moments of production and reproduction. Depth must be the knowledge of the laws governing the preparation and sale of all substances of nutritional interest for animals raised.
Course contents summary
The first part of this course takes into account the main aspects of a packet that regulate energy metabolism, protein, vitamin and mineral putting particular emphasis on all the factors that may affect the performance and health status of the animals.
In the second part vencono examined aspects of nutritional requirements and techniques of formulating rations for the main farmed species.
The third part of the course assesses the major occupational diseases resulting from dietary errors, incorrect use of animal feed as well as feed additives.

The course of ANIMAL FEEDING, NUTRITION AND TECHNICAL FEEDSTUFF provides for the holding of lectures by the projections of power point slides and other materials to help engage the student in the different phases of the educational activity. Classroom activities are designed to raise awareness of the current computer applications for animal feed as well as tutorials at farms with the aim of identifying practical solutions to the problems outlined theoretical.
Assessment methods and criteria
The oral examination is expected to ensure the achievement of the objectives of the course. The student must demonstrate expertise detailed issues that govern the basis of animal as well as demonstrate adequate mastery of nutritional factors that may cause and / or the cause of the main technopathies breeding. Through questions about the role of power in the process of optimization of performance and prevention of nutritional disorders will be determined whether the student has achieved the aim of applying the acquired knowledge.
