Animal feed and feeding (5 cr)

Evaluation scale

1-5

Objective

The students recognize the nutrients in feeds, principles of feed evaluation as well as the digestive systems of animals and understand their significance in feeding. They know the principles and objectives of feed planning, and are able to evaluate how a change in the proportions of the components of a diet affects the amount and content of nutrients. They can assess the results of a feeding plan and put it into practice and can calculate the amount of feed needed for the animals annually. They are familiar with the technology used in feeding.

Content

Nutrients, composition and feeding value of typical feeds, farm animal digestion systems, feed planning and its relationship with animal welfare and health, assessment of the results of feeding and feeding technology.
