ANSC30290 Grassland Management and Applied Dairy Nutrition

Academic Year 2022/2023

This undergraduate module targets students specialising in Dairy Science, and addresses the principles of dairy cow nutrition within grassland systems. It consists of a mix of lecturers, seminars, practicals and field trips on the theory and practice of grassland nutrition based on the latest research information. The dairy cow nutrition component will quantify the basic nutritional requirements of the pasture fed dairy cow, provide methodologies to evaluate nutritional status of dairy herds in practice and examine the opportunities for efficient strategic supplementation at grazing. The grassland component will provide an appreciation of the objectives and management technologies for grazing systems; examine the potential from reseeding and merits of new grass cultivars; investigate strategies to increase nutrient efficiency within pasture systems and identify key performance indicators for high productivity grazing systems.

Learning Outcomes:

On completion of this module the students should be able to:
Clearly and concisely explain the key success indicators of pasture based milk production and develop the techniques to critically evaluate the technical efficiency of a grass-based dairy farm;
Competently understand and apply a variety of modern grazing management technologies throughout the grazing season to achieve high animal performance;
Describe the nutritional status of a dairy herd at a point in time and accurately project the change in feed supply for that herd over time;
Understand and evaluate the nutrient efficiency of a dairy farm system, identify soil fertility limitations and potential mitigation strategies where poor nutrient efficiency is observed.
