Course abstract

Learning of the Study course gives an idea and provides insight into the economic importance of the cattle farming, describing general situation and perspectives of the development of that specific economical field in Latvian and other countries. In the study process insight about the most popular cow breeds will be given, characteristic features and influencing factors of the productivity will be analyzed, problems and solutions of the herd reproduction will be discussed, different uses of animal evaluation methods will be reviewed.

Learning outcomes and their assessment

Students will gain theoretical knowledge about suitability of different cow breeds for milk and / or meat production, breeding and feeding technologies, production and its quality assessment principles. Knowledge is assessed by the results of 1st, 2nd, 3rd and 4th tests.
Will acquire skills in organization of milk and/or meat production process, assessment of suitability of housing technologies for different breed, age group and different using direction cows. Students will acquire skills necessary for filling herd documentation, registration of quantity of obtained production and in assessment of the traits characterizing productivity. Skills are assessed according to the explanations and conclusions given during the practical work.
As a result of the study course students will be competent to assess the suitability of the animals of the particular cow breed to the chosen production direction, to evaluate the compliance of the applied holding technology with the welfare requirements and to independently analyze the productivity and reproduction indicators of the animals. Students will be competent to recommend for the farmers the most appropriate solution for the sustainable development of the farm. The acquired competencies are evaluated by the quality of conclusions and explanations in seminars and practical works, as well as by the answers on test and exam questions.

Requirements for awarding credit points

Successfully written 4 tests, completed and graded practical works, and passed written exam.

Description of the organization and tasks of students’ independent work

The student independently studies literature, collects the obtained information, publicly presents the results of practical work.

Criteria for Evaluating Learning Outcomes

Independent work is evaluated with the grade, depending on the presentation of prepared material. Tests are evaluated by the answers to questions. As passed are considered those knowledge and skill evidence that in 10 point scale scored at least 4.
Each individual practical work after its development is marked with “passed’ or “failed”. At the end of practical works is planned test that is evaluated with the grade in 10 point scale. The rights to write a test have those students that has passed all practical works in recent topics.
Students who have successfully passed tests and practical tests are admitted to the examination.
At the end of the course students take a written exam, the ticket consists of 4 questions, of which 3 are questions from topics in lectures and 1 question is from practical work topics. Each question represents 25% of the final grade.
