Course abstract
Dairy husbandry as an important sphere of economics. Perspective of development of dairy husbandry in Latvia and other countries. Cow breeds, history of forming, directions of fertilization, prevalence. Factors, affecting milk and meat productivity. Reproduction of herd. Growing of heirs. Evaluation of cattle. Organization of pedigree record.
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 seminars and 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 in 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 during the discussions, the individual work presentations, the tests and the conclusions given at the end of the exam.

Requirements for awarding credit points
Successfully written tests, completed and graded practical works, public presentation of independent work in the classroom and successfully 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 and independent work.
Criteria for Evaluating Learning Outcomes
Independent work is evaluated with a mark after the presentation of the prepared material and tests, according to the given answers. Positive grade receives only those works that are rated at least 4 points.
Practical works are evaluated after their development with a mark pass or fail. . At the end of the practical works, students are writing test, which is graded on a 10-point scale. Successful evaluation in practical works can only be achieved if all the practical works developed have received a positive assessment.
Students who have a positive assessment in tests and practical works and also successfully presented the topics of independent work are admitted to the examination. Students who receive grade higher than 7 in all forms of examination during the study course, do not have to take the exam, their grade is calculated from grades in theoretical course (50%) and practical work (50%).
