INTRODUCTION
Proper nutrition is fundamental to good health and repro-
duction. There is an ethical responsibility to provide
captive animals with appropriate foods that will satisfy
their nutrient requirements. Nutrients also affect growth
and development, including having effects on epigenetic
processes. Thus, early nutrition can influence eventual
phenotype. In an extreme example, many nutrients are
methyl donors (e.g. folate, vitamin B 6 ). The levels of
methyl donors in the diet can affect the level of methylation
of susceptible genes, modifying their expression. For
example, both coat color and the propensity for obesity in
agouti mice is affected by the levels of methyl donors
(folate, vitamin B 6 , choline) in the maternal diet ( Waterland
and Jirtle, 2003 ). Thus, differences in nutrition can have
many and varied affects on animals, including significant
effects on phenotype across generations.
In the context of biomedical research, nutritional
considerations are very important for the outcomes and
interpretation of experimental data. Evolution has produced
regulatory mechanisms that allow animals to survive and
reproduce on a range of nutritional planes. That means that
