Nog een menig die de jouwe aardig onderstreept denk ik Frans.
From "Equine Clinical Nutrition" Lon D.Lewis
"Ascorbic Acid (Vit C) is synthesized from glucose in the liver of
all animals except - man, several primates, Indian fruit bat, guinea
pigs and a few birds, fish and invertebrates."
"For other species it is not an essential dietary nutrient, however
it is physiologically essential for all species".
Horses do not need Vit C in their diet, however it has been shown,
in some species, that some stressful conditions might increase the
requirement for ascorbic acid beyond the animal's ability to
synthesize it and although it has not been demonstrated in the horse
this does not say it can't happen.
"Ascorbyl palmitate is the prefered ascorbic acid oral supplement
for the horse."
The last quote is "However, remember that Vit C supplementation to
the horse under any conditions has not been shown, even in an
individual, to be of benefit, and although some studies in other
species under certain circumstances suggest a benefit, other studies
suggest harm from Vit C supplementation."
Vitamin C is certainly involved in collagen production and many of
the signs of Vit C deficiency reflect a lack of normal collagen - in
the species that require it in their diet.
In my opinion, Vit C deficiency is very unlikely to be involved in
the development of laminitis. In the stressed horse with laminitis
it could theoretically possibly be of benefit.
