Feed ration planning in dairy cattle herds


Graduate School of Science and Technology at Aarhus University


Objectives of the course:

The objective of the course is to qualify the students to plan, evaluate and discuss feeding rations in commercial dairy herds. The teaching, student forum and the teacher collegium will be international with a focus on a Scandinavian setting.

 

Learning outcomes and competences:
At the end of the course, the student should be able to:

  • Describe and generate plans of feed supply: crop rotation, crop production, allocation of feeds among animal categories
  • Describe and discuss feed production: quantity, quality, conservation, processing
  • Describe and combine feed analyses and evaluation: energy, protein, input parameters for different systems
  • Describe and discuss elements of ration formulation: nutrient requirements, response curves, individuals/groups, feed intake
  • Describe and compare math models describing digestion and metabolism
  • Describe and compare feed planning and evaluation tools (NorFor and others)
  • Apply the NorFor tool in a real life situation of feed budgeting and planning
  • Discuss and relate feed ration optimisation to optimal production level, cost minimisation, diminishing return

 

Course parameters:
Language: English
Level of course: Combined Master’s and PhD course
Time of year: August 2019 (Summer University)
No. of contact hours/hours in total incl. preparation, assignment(s) or the like:
The workload is distributed as follows:

  • Preparation for the course: Self-study (20 h)
  • Course: Lectures, exercises, group work, excursions (100 h)
  • After the course: Report writing under supervision (30 h)

Capacity limits: 25 participants

 

Compulsory programme:
Presence at all course activities and active participation in the course and in the group work is obligatory.

 

Course contents:
Before the course, students individually prepare a report (2 standard pages) and presentation (10 min) about their current and previous national feed evaluation system for dairy cattle. During the course students are trained to plan, evaluate and discuss feeding rations in commercial dairy herds using the NorFor system, and to discuss elements of this based on lectures, literature, farm data and cases, excursions, individual and group discussions, exercises and report writing. After the course students will prepare a group report (3-4 standard pages per student) on feed budgeting and planning in commercial dairy herds with a focus on ration optimisation to optimal production level and cost minimisation. At the end of the course the groups present their report outline and status.

 

Prerequisites:
Enrolment as PhD student. B.Sc. including courses in livestock animal physiology and nutrition.
