Nutritionl Support Of The Nervous System Flashcards
What will malnutrition during pregnancy lead to
Reduction in brain cells
Reduction in myelin production
Reduction in number of synapses
Altered neurotransmitter systems
What part of pregnancy has the greatest effect on cell proliferation
Early
What is later pregnancy anancy nutrition important for
Cell differentiation (development of neuron synapses + dendrites)
Which macromolecule is essential for structural composition of the brain
Essential fatty acids
When is fat deposed in the foetus
Third trimester
What is the function of lipids in the brain
Cell membrane
Lipid signalling
Altering gene expression
What fatty acid is the brain very rich in
Omega 3
What is the effect of essential fatty acids in the brain
Gene expression
What is Docsohexaenomic acid (DHA)
An omega 3 fatty acid
What does DHA effect
Membrane fluidity
Transport in neural cells
How are DHA deficient animals treated
Given an n-3 fatty acid diet
This may adverse the effects on the DHA deficiency during neurodevelopment
What are the effects of a DHA deficiency
Suboptimal cognitive and visual function
What does increases omega 3 in a puppy diet cause
Improved cognitive function
Better memory and navigation
What does an omega 3 supplemented diet in pregnant/ lactating bitches
Puppies with higher retinal function
Better cognitive function
(Easier to train)
What is Arachidonic acid
Omega 6
What are the fatty acid levels in aggressive dogs
Higher omega 6
Lower DHA
What is a good source of omega 3
Cod liver oil
Where do herbivores get most omega 3
Forage
Where do herbivores get omega 6
Grains
What fatty acids does grass supply
EPA
DHA
What is the function of vitamin E
Maintaining normal neurological function
What is a source of vitamin E in herbivores
Pasture - however overgrazing causes obesity (over fed - undernourished)
What is the function of copper for lambs
Normal brain and muscle control
What reduces copper uptake
Iron
Molybdenum
Sulphur
AKA grazing pasture with High levels of iron and molybdenum
