I couldn't find your chosen feed either , but I did stumble across this:
The feed of choice is generally corn. Corn is economical, and whitetail deer love it. Is it good for them? Well, yes and no. It depends on the time of the year, and the condition of the available forage. In the fall and winter when cold weather begins to arrive, corn is an excellent source of energy for deer. It helps to keep their internal furnaces stoked up to help them face the cold, and often wet or icy weather. Corn only has about 7 or 8 % protein, but during the fall and winter, deer don't generally need a high protein diet nearly as much as they need it during the following months. They do need something in their bellies, though, and if a deer is hungry, corn sure beats the heck out of nothing.
I only use corn , let Mother Nature and the local farmers provide the nutritious stuff .
