Course abstract

The study course will give for students the opportunity to familiarize themselves with the growth and development characteristics of different animal species, classification of livestock breeds, body constitution, productivity traits, breeding methods, animal selection and its importance in animal breeding. Students will acquire knowledge about feed nutrients and their role in nutrition, feedstuffs and their quality, their role in production and provision of health as well as about principles of forming balanced and economically justifiable feed ration for different species, age and productivity level livestock

Learning outcomes and their assessment

After completion of study course, students will acquire:
• knowledge about classification of different livestock breeds, speed and intensity of growth, different types of constitution and methods of body conformation trait evaluation as well as the effect of body conformation traits on livestock productivity traits, students will find out about role of selection work in animal husbandries effectivity increase. Students will acquire knowledge role of nutrients in livestock ration, production and norming of feed ration (developed and defended practical works, passed tests and exam about theoretical course)
• skill to evaluate growing peculiarities of different animal species, productivity level, understand livestock selection principles and importance of animal breeding as well as to choose more suitable feedstuff for specific animal species and plan feed ration depending on animal productivity level (developed practical works, passed test).
• competence choose livestock species and breeds suitable for farms direction and housing technologies, plan balanced feeding and to use obtained knowledge for development of term papers and bachelors thesis. (passed tests and passed theoretical exam)

Requirements for awarding credit points

The study course consists of two parts: animal breeding (1.-8.) and animal nutrition (9.-16.). Recommended attendance to lectures, mandatory attendance to practical works. Passed tests, developed and positively graded practical works. Written exam about topics, covered during course.

Description of the organization and tasks of students’ independent work

During semester student individually studies literature, prepares for tests, if necessary, uses office hours.

Criteria for Evaluating Learning Outcomes

Evaluation in the course is possible obtain only when are developed and passed all practical works, passed all 3 tests. Written exam.
Summed grade is calculated as mean average from animal breeding and animal feeding test results.
