Learning Outcomes

On successful completion of this module students should be able to:

1. Evaluate current and future silage production systems.

2. Review and evaluate scientific literature in relation to silage fermentation and microbiology and apply results to the evaluation of inoculants and other silage production additives.

3. Discuss the various systems used in silage evaluation and be able to use the information to help design optimal diets for ruminant livestock.

4. Assess the potential environmental impacts of silage production and evaluate strategies to reduce the risk to the wider environment.

Brief description

This module explores the way in which research is used to develop more efficient ensilage systems for forage and grains fed to farmed livestock. The module will detail practices involved in pre-ensiling crop management, harvest and storage, and effective feeding strategies. In addition the environmental impact of silage production will be considered along with practical measures for mitigating against potential harm
Through the distance learning programme of students will evaluate the role of ensiling conventional and novel forage crops and investigate the factors underpinning the development of such systems. Current research being carried out in IBERS will have a significant impact on the precise module content.


This module will comprise 20 hrs of formal input and will cover the following areas:
  • Silage production and ensilage systems
  • Silage evaluation
  • Silage fermentation and microbiology
  • Inoculant development
  • Ensilage and preservation of a alternative feed crops and its potential to affect future livestock feeding practice
  • Pathogen transfer and food safety in silage fed animals
The module will feature a range of lectures, interviews with key researchers and some film material that will teach students about current advances in silage. The fundamental principles of each of topic will be conveyed to the student in a lecture format. In addition, key research publications and interviews with researches will form the basis of a 'case study' demonstrating how research is driving innovation in each area. An assessed 'forum post' associated to each unit of study will ensure students understand the key information presented and can synthesize and present their arguments to other students. Students will also be expected to reply to other student forum posts to encourage further dialogue around each topic. In addition students will be asked to produce a assessed presentation aimed at conveying the information gathered from the module and publications to the wider farming community. This activity will assess both the students understanding of the subject matter, and their ability to communicate difficult concepts. An assessed report will test the students ability to research and build their own 'case study' mirroring and building on the information contained within the module.
