Aims of the module
This module aims to provide the student with a basic understanding of the structure, function, and biosynthesis of the major organic constituents of living organisms, and the processes of growth, excretion and energy generation in animals. It will also provide awareness of biochemical changes and microbial activity in nutrient cycling/decomposition; composting, agriculturally important fermentations and the poisoning of farm animals. The ecological impact of some agricultural pollutants will also be examined.

Learning outcomes
On completion of this module students will be able to:

• describe the biosynthesis of organic macromolecules and their importance in living organisms;
• understand the biochemical aspects of growth, excretion and energy generation in animals;
• describe the biochemical aspects and role of microbial activity in a range of important agricultural processes;
• assess the ecological impact of some agricultural pollutants.

Syllabus / Curriculum design
This module will be presented as a lecture course with four practical sessions to complement and highlight parts of the lecture material. A visit to the Institute of Grassland and Environmental Research will give students an awareness of the practical applications of biochemical and microbial techniques.

Content: Description of molecules; Biosynthesis; Enzymes; Excretion; Energy; Growth; Nutrient cycling and decomposition; Anaerobic digestion of farm wastes; Composting; Silage and Rumen; Poisoning; Biodegradation of xenobiotics; Agricultural pollution issues
