calcium-- in veterinary aswell

[madgeymoo]

i was just wondering when feeding calicum could this cause tying up as in normal muscle function, calcium is cycled within the cell. To contract the muscle, calcium is released in response to electrical stimulus from the nervous system. To relax the muscle, the mitochondria (the energy-producing centers in the cells) return the calcium to the small bodies where it is stored. When the mitochondria lose their ability to recycle the calcium, it begins to build up, leading to constant contraction.

would this cause a TB horse to tie up when he is normally fed one teaspoon a day

My understanding is that calcium is very well regulated and excess is excreted in the urine. I'd be more inclined to think that low dietary availability of calcium (through short supply or unavailability due to binding by other dietary components or a high P level) would be a potential player?

There will be others know way more about this than me, but i *believe* that magnesium and calcium need to be in correct ratio for them both to be utilised correctly.

Will watch this with interest
