Prerequisites: Knownledge required:
plant and animal biology
general and organic chemistry, biochemistry
Target skills and knowledge: Knownledge:
1) Chemical and nutritional characteristics of feeds
2) Digestion and metabolism in monogastrics and ruminants
3) Methods for chemical and biological evaluation of feeds
4) Energy and protein values of feeds (Enenrgy and protein systems)
5) Nutrient requirements of farm animal
6) Control of feed intake
7) Formulation of diets and rations
1) Identification of feeds;
2) Computation of the chemical and nutritional composition of feed mixtures and rations from feed ingredients data;
3) Computation of nutrient requirements of monogastric and ruminant species;
4) Feed intake, prediction and control;
5) Formulation of mixed feed and rations for monogastrics and ruminant species
6) Computation of N intake, retention and excretion;
Examination methods: Two kinds of examination
10-12 practical exercises of computations (problem solving ability);
2-3 questions to evaluate knownledge and theoretical ability to put in connection the various issues studied during the course;
1 identification of feeds
4-5 practical exercices of computation to evaluate the acquired ability, success is required to have access to the oral part of the examination;
10-15 questions to verify knownledgeand ability to put in connection the various issues studied during the course.
Assessment criteria: Criteria for evaluation are:
1) status of acquired knownledge;
2) ability to solve practical problems about the characterization of the chemical and nutritional properties of feeds, feed mixtures and diets, and quantification of nutrient requirements.
3) ability to identify strategies for improving feed intake;
4) ability to formulate complete feed and rations;
5) ability to quantify nutrient intake, retention and excretion from simple technical indexes on farm basis.
Course unit contents: credit 1: Feeds: forages, concentrates and by-products, chemical evaluations, analysis of feed labels;
credit 2: Digestion and metabolism in ruminants and monogastrics
credit 3: Biological evaluation of feed for ruminants. The energy and the protein values of feeds. Methods for chemical and biological evaluation of feeds.
Credit 4: Biological evaluation of feed for monogastrics, energy and protein values of feeds;
Credit 5: Nutrient requirements for ruminants. Energy and protein systems. Computation of nutrient requirements of livestock;
Credit 6: Nutrient requirements of monogastrics. Enenrgy and protein systems. Computation of nutrient requirements of monogastric animals.
Credit 7: Feed intake, prediction, and strategies to control feed intake;
Credit 8: Feed formulation, feed mixtures, rations and feeding plans. Technical indexes of feed efficiency, computation of nutrient excretion from farm animals.
Planned learning activities and teaching methods: Frontal lessons, exercises and laboratory activity
1) Frontal lessons and exercises are integrated, so that after the theory the student have to solve practical problems with data coming from (i) actual farms; (ii) laboratory data, (iii) feed database, (iv) mathematical models.
2) The ability to solve problems at individual or group basis is routinary tested with specific exercises of computation with examples taken from the practice;
3) Toward the middle and at the end of the course simulations of final examination are proposed to the students.
4) Exercises, with or without solutions, are available in the web site.
5) Laboratory: practical lessons in a laboratory for chemical and biological analysis, practical lessons in animal farms (dairy and beef cattle, pig)
6) The teacher is available for individual or group meetings to solve dubts about the programs or for insight, even after that the course is concluded.
Additional notes about suggested reading: 1) power-point files presented during the course;
2) Files for computations of the chemical and nutritional composition of feeds and diets, developed with the student during the course;
3) esercises done dutring the course with solutions.
Thse materials are available in the web site of the course.
The book suggested has some lack of information, particularly on: the evaluation of protein value of feeds for monogastrics,and methods for predicting nutrient requirements.
