The condition for successful completion is active participation in practical exercises, submitted exercise protocols, successful completion of the written test (minimum 51%) and successful presentation of the semester work.

By completing this subject, the student will acquire basic knowledge in the field of technology for processing feed components and additives, as well as the industrial production of feed for companion animals. After successful completion of this subject, the student will have theoretical and practical knowledge of methods of processing feed components and their influence on nutritional and dietetic properties. He will gain knowledge about the technological procedures of industrial feed production for individual companion animals (dogs, cats, small mammals, reptiles, birds, horses) and the types of diets used.

The subject outline is aimed at achieving basic knowledge about the history of the industrial production of dog food, raw materials for the production of food, technological modifications of feed components, technologies for the production of wet, semi-moist and dry dog food. An important area is the question of the safety of feed production from the point of view of limitations in the production and storage of the resulting products. The subject also includes internal control of the production process using the system of risk analysis and determination of critical control points (HACCP), as well as external control by state authorities working in the field of feed production safety.
