Learning objectives
Nell'ambito del corso integrato, attraverso un approccio metodologico applicativo, verranno fornite nozioni relative alla presenza di residui di origine naturale o da somministrazione illecita e di contaminanti nei mangimi, ai principali indicatori biochimico clinici ed ematologici per il monitoraggio di disordini metabolici di origine nutrizionale negli animali di interesse zootecnico.

ATTENDING STUDENTS
Clinical biochemistry of nutrition
Course syllabus
OBJECTIVES OF THE TEACHING MODULE
To provide students skills in theory and practice for producing and interpreting results of laboratory analyses for measuring molecular markers of nutritional-related metabolic disorders in farm animals.

PROGRAM
Theoretical training (16 hours)
> Molecular basis of animal nutrition:
- Chemical and biochemical characteristics of nutrients (3h).
- Nutritional biochemistry: absorption, oxidation/reduction reactions in metabolism, gut fermentations (4h).
- Integration of metabolism and endocrine regulation of nutrient metabolism (3h).
> Clinical biochemistry methods for measuring molecular markers of nutritional diseases:
- Analytical techniques and instruments used in clinical biochemistry laboratories (5h).
- Source of error and variability of laboratory's test result (1h).

Practical training (16 hours)
Students will develop skills in calculation routinely used in clinical biochemistry laboratories.
- Different ways of expression of quantity and concentration (4h)
- Conversion between units of measurement (4h)
- From instrument reading to analyte concentration (4h)
- Laboratory mathematics, computer elaboration of raw data and graphical representation of clinical biochemistry analysis results (4h)

EXAMINATION PROCEDURE
Oral examination.

Toxicology and contaminating feed
Course syllabus
FEED TOXICOLOGY (3 CFU, 32hours)

OBJECTIVES OF THE TEACHING MODULE
The course will provide students with information about the presence of residues of natural origin or from illegal administration and of contaminants in the feed and main methods of detection.

PROGRAMME
Frontal Lessons (16 hours)
- Endocrine Disruptors: classification, definition, toxicity (6 hours)
- Phytotoxins in raw materials and in feed and species-specific toxicity (4 hours)
- Polychlorinated biphenyls (PCBs), dioxins and brominated organic compounds (4)
- Radionuclides (2 hours)



Practical excercises (16 hours)
After a two hours theoretical class about laboratory methods, students will execute, in two working days, quantitative analysis on pelleted feed for active ingredients of natural origin or from environmental contamination. From the screening analysis through ELISA tests to the HPLC/MSn confirmation analysis according to the dictates of the Commission Decision 2002/657 / EC.
