Learning objectives
The course aims to provide students with knowledge of the feeding and breeding techniques for various animal species of zootechnical interest (dairy and beef cattle, small ruminants, pigs, and poultry). It involves studying some of the impacts of breeding systems on the production and quality of animal products, the environment, and animal welfare. Another objective of the course is to clarify the role of zootechnical systems in agriculture, defining types of breeding for sustainable animal husbandry.
Expected learning outcomes
Upon passing the exam, the student will have gained fundamental skills in animal nutrition and feeding, including basic abilities in rationing for major livestock species and tools for the technical evaluation of breeding systems with different production address.
Single course

This course can be attended as a single course.

Course syllabus
Module 1 - Breeding systems of the main income species

- Cow's milk production: factors influencing milk production and quality; milking; breeding techniques for dairy cows; reproduction and fertility; breeding of replacement animals.
- Beef production: main beef cattle breeds; chemical, physical and nutritional characteristics of the meat; growth and development; main factors influencing meat production and quality; breeding techniques of the main categories of beef cattle (white veal, light and heavy beef); meat production according to the cow-calf system.
- Pigmeat production: main pig breeds; sow rearing and reproduction; breeding of replacement gilts; rearing techniques for light and heavy pigs.
-Quality and safety elements of products of animal origin (measurable parameters or to be managed in the process)
- Modern animal husbandry for environmental sustainability
- Notes on: poultry production, sheep, goat and buffalo production.


Module 2 - Feeding of the main income species

- Chemical constitution of feeds: carbohydrates, lipids and nitrogenous substances. The main chemical analyzes for the determination of: dry matter, ashes, proteins, lipids, fibers and starch. Summary of mineral and vitamin nutrition. Factors regulating feed intake. Fibre: dietary and nutritional function for ruminants and monogastrics. Digestibility and factors influencing it. The basics of energy and protein metabolism in ruminants and monogastrics.
- Evaluation of the analytical-nutritional characteristics of the main zootechnical foods and techniques for their production. Feeding techniques of the main species of livestock interest (dairy and beef cattle, pigs, poultry, sheep and goats) in the various types of farming, with particular reference to pigs and dairy cattle in intensive farming.
- The major pollutants deriving from farms: nitrogen, phosphorus, heavy metals, ammonia and "greenhouse effect" gases. How to calculate an animal's nitrogen balance. Evaluation of some feed strategies aimed at reducing the excretion of the main pollutants: importance of the best intake/requirement ratio; the "multiphase" power supply; the concept of limiting amino acids; the use of commercially available additives and amino acids in rationing.
- Main nutritional requirements of livestock, in the various growth and physiological stages. Rationing techniques, practical examples of diets for ruminants and monogastrics with the use of IT packages.

Assessment methods and Criteria
The exam consists of an oral test. The evaluation criteria are based on adherence to the question, on the ability to identify the salient aspects of the subject, on the correctness of the technical language. The vote is expressed in thirtieths. Students with SLD or disability certifications are kindly requested to contact the teacher at least 15 days before the date of the exam session to agree on individual exam requirements.
