Course abstract
The aim of the study course is to get to know the situation of animal breeding mechanization in Latvia, the system of animal breeding machines, its formation and characteristics, modern milking machines and robots, milk meters and flow adaptors, milk cleaning and cooling equimentanimal feed preperation animal breeding management system.
Learning outcomes and their assessment
Knowledge - about the state of livestock mechanization in Latvia and its development trends, modern technologies and equipment used for milking cows and pre-processing of the obtained milk, preparation of fodder, as well as about dairy farming management. Knowledge is assessed in Test 1 and laboratory work.
Skills - to know and evaluate various technological equipment for milking cows, milk pre-processing and fodder preparation, based on their construction and technical parameters. Skills are assessed in test 2 and laboratory work.
Competences - to acquire knowledge and skills necessary for agricultural engineers, taking care of modernization of animal husbandry technology and mechanization. Competences are assessed in tests.
