Summary module description:

This module aims to develop students’ understanding of the requirements of farm and companion animals for energy, protein, minerals and vitamins, and how the ability of a feedstuff to provide these nutrients can be assessed. An overview of the important relationship between animal and human nutrition will be provided as well as the impact of animal nutrition on the environment will be provided. Exercises on diet formulation will be used to integrate nutrient requirements of animals and feed composition in practical, applied feeding scenarios. In addition there will be one practical exercise involving excision of a digestive tract, which will provide the students with an overview of different segments of a digestive tract and their roles


Aims:

This module aims to develop students’ understanding of the requirements of farm and companion animals for energy, protein, minerals and vitamins, and how the ability of a feedstuff to provide these nutrients can be assessed. An overview of the important relationship between animal and human nutrition will be provided as well as the impact of animal nutrition on the environment will be provided. Exercises on diet formulation will be used to integrate nutrient requirements of animals and feed composition in practical, applied feeding scenarios. In addition there will be one practical exercise involving excision of a digestive tract, which will provide the students with an overview of different segments of a digestive tract and their roles


Assessable learning outcomes:
By the end of the module it is expected that the student will be able to:
• Explain the physiochemical basis of requirements for energy and protein and factors controlling feed intake
• Describe methods for the evaluation of feedstuffs to provide energy and protein
• Explain the function of minerals and trace elements and key interactions with vitamins in animals
• Discuss the impact of animal nutrition on the environment and/or on human food composition
• Perform nutritional calculations and produce simple and software optimised diet formulations
• Describe and discuss the anatomical and physiological functions of a digestive tract and relate these to dietary adaptations

Additional outcomes:

Students will gain experience in dissection of a digestive tract and the presentation of practical dissection findings by oral and written means. Students will also gain an insight into the systems used to define energy and protein requirements for animals.


Outline content:

The lecture content covers:

? Definition and measurement of gross and digestible energy content of feeds and factors affecting digestibility

? Definition and measurement of metabolisable and net energy

? Energy requirements for maintenance, work, growth, lactation and gestation

? Protein quality for non-ruminants in terms of essential amino acids and biological value

? Nitrogen metabolism and microbial protein synthesis in ruminants

? Protein requirements for animals

? The evolution of digestive diversity and comparative nutrition in the animal kingdom

? Function of key minerals and trace elements and key interactions with vitamins in animals

? The role of computer software for optimising diet formulation

? Feed science and feed characterisation in the laboratory

? Relationship between animal and human nutrition.

? Animal nutrition and the environment


Brief description of teaching and learning methods:

There will be two 50-minute lectures per week, followed by up to two hours of tutorial time devoted to exercises for solving nutritional problems which lead to coursework. On one week there will be a practical exercise involving excising a digestive tract. A short presentation and a written report identifying the various anatomical regions of the digestive tract, their physiological functions and linking diet adaptations to anatomical and physiological functions will contribute to assessed coursework.

Formative assessment methods:

Penalties for late submission:
The Module Convenor will apply the following penalties for work submitted late, in accordance with the University policy.

  • where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

  • The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
    You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

    Length of examination:
    A one and a half hour examination requiring answers to all short answer questions in section A, the answer to one of two long answer questions in section B and the answer to one of two long answer questions in section C.

    Requirements for a pass:
    A mark of 40% overall.

    Reassessment arrangements:
    By re-examination.
