Course abstract

The aim of the study course is to inform the students about milk, meat and egg production technologies including domestic animal selection, reproduction and handling, technological design of animal farms, animal feeding, animal breeding products and by-products as well as about collection and utilization of waste.

Learning outcomes and their assessment

Knowledges - about technological processes of milk, meat and egg production, as well as quality assurance of these products, using modern working methods. Knowledge is assessed in laboratory and practical work, as well as in tests.
Skills - the technological processes of livestock production, as well as to develop their modernization projects in order to improve the quality of the produced products and achieve high work results. Skills are assessed in practical work and tests.

Competences - to acquire knowledge and skills that are necessary for agricultural engineers, taking care of the improvement of the technological process of production and ensuring the quality of the produced products. Competences are assessed in laboratory work and tests.

Requirements for awarding credit points

The exam can be taken after listening to a lecture course, developing practical work and successfully writing both tests. Type of examination - examination with assessment.

Description of the organization and tasks of students’ independent work

Preparation for tests using the literature indicated in the study program and consulting with the lecturer of the study course.

Criteria for Evaluating Learning Outcomes

Assessment of the study course depends on the cumulative assessment of the examination task and study course tests.
Students can have a successful grade for the test and examination, if at least 50% of the test questions are answered correctly.
Examination grade is calculated as the mean average of the average results of the tests passed in the animal farming and plant growing mechanisation sections.
