According to the University of Maryland Medical Center, fats are «crucial for
normal growth and development and for brain function,
and they help to stimulate hair
and skin
growth, regulate metabolism,
and maintain bone health
and the reproductive system.»
Humane Canada believes that experiments
and activities involving live animals should be limited to observations of the
normal living patterns, behaviour,
growth,
and development of domestic animals, or wild animals in the free living state or in those zoos or aquaria which
maintain animals in suitable naturalistic environments which meet the health, emotional
and behavioural needs of each species of animal.
