Benefits of live feeding?

Not much loss but loss just the same.

And variable based on freezing technique, length of storage, storage temp, and even the individual prey animal being frozen and thawed. Also, when calculated on a Gaussian gradient, the difference falls with-in the circular error probable of the data presented...meaning, there may be a slight difference, and, there may not be. Also, if I'm not mistaken, the study you found and posted was done without a control group.

*EDIT: In the interest of accuracy, I re-ran the data from the 2003 USDA study and the only factor that falls outside of the Gaussian error gradient is Vitamin C. I do not believe rats are a significant source of Vitamin C, so I'll let you draw your own conclusions about that part of the data.

Watching a snake stalk, strike, and constrict (in a reasonable time frame too). You know the exciting day of the week where it's more than a pet rock.

Mine stalk, strike, and constrict F/T, so I wouldn't see a real difference with live. I'm old enough to have had a pet rock, and I can assure you, no BP of mine is a pet rock.
