93971 - PRECISION FEEDING IN LIVESTOCK

Conoscenze e abilità da conseguire

At course completion, the student possesses knowledge on: the theoretical bases on which to model the needs of livestock; precision feeding of livestock; determining the nutrients available in feed and the precise formulation of diets in the application of nutritional needs of individual animals or groups of animals. In particular, the student possesses the skills to: quantify the changes in nutritional needs that occur over time and the variation in nutritional needs that exists among animals, as well as to minimize the use of productive resources; organize the combination of: 1) automatic collection of animal data, 2) data processing, and 3) control system actions of the practical satisfaction of needs

Contenuti

Traditional and modern precision feeding: general scopes and advantages. Nutrient contents of animal products and the theoretical bases of the partition of nutrients, of the feeding requirements and of the control of feed intake. General framework for the quantification of the variation in nutritional needs with the progression of the production, and to take into account of the changes due to different phenotypic and genotypic values of the animals. Feeding methods and distribution. Importance of punctual collection of productive animal data, data processing, and response actions to adjust the practical feeding to satisfy productive goals. Method of feed formulation and tools to improve the precision of the feed mixtures. Least cost feed formulation and pre and post-hoc tools to quality control. Feed additives and the optimization of their supply.

Metodi didattici

Lesson, visits to leading plants of animal production and feed compund plants, applications with software and practical exercitations.

Modalità di verifica e valutazione dell'apprendimento

The evaluation of the course PRECISION FEEDING IN LIVESTOCK takes into account jointly the level of knowledge and skills acquired by the student in relation to the contents of course.

The assessment of learning is done through an oral test during which the knowledge and skills acquired about each of the theoretical and practical teaching units application will be assessed. The assessment is expressed out of thirty, based on the average score obtained after a total of 3 question, and based on the correspondence of the responses to the training objectives of the course.

In details, here is the possible score grid for oral examinations I would like to adopt in the near future:

- a very thorough knowledge of the topics addressed in the course, together with high skills of critical analysis, connection and a sure command of specific terminology will be evaluated with the maximum score (30-30L);

- a thorough knowledge of the topics addressed in the course, together with good analytical and critical skills and the possession of a sure command of specific terminology will be evaluated with good marks (27-29);

- a technically adequate preparation and a sufficient analytical capacity, even if not particularly articulated, expressed in a correct language, will produce fair evaluations (23-26);

- sufficient preparation and capacity for analysis, expressed in a language which is barely formally correct, will determine the sufficiency (18-22).

All dates, times and locations of the examinations are published on the website of the degree course. To subscribe use the web application AlmaEsami.
