VV,
In reading the page you provided the link to, I found this:
Prevention
Clearly, prevention of GDV is preferable to treatment. In susceptible breeds, feed two or three meals daily and discourage rapid eating. Do not allow exercise for two hours after a meal. As previously mentioned, some owners feel that certain bloodlines are at greater risk and choose to have gastroplexy performed as a prophylactic measure. ...

I did discuss this condition (twisted gut) with my vet. She actually brought it up and recommended small, more frequent feedings, thus the split normal feedings of morning and night. She noted that she's treated several cases where the dog was fed once a day a large meal.
I am very familiar with this life threatening condition (twisted gut) in horses, having dealt with several cases and having witnessed a loss of a horse to it.
So, per her recommendation and in line with what your link recommended, I have been feeding light the morning of the hunt, ensuring a few hours of inactivity (drive to the hunting grounds) after feeding before hunting. Is this different than other information you have?
One last thing the vet recommended, add water to the dry feed to ensure it breaks down in the intestine quickly and thus preventing large accumulation of food which can lead to a twisted gut.
