\"Still Hunter\" said:Do you think a mule deer feeding on sage will taste the same as one feeding on apples?
Do you think a mule deer who is shot, and falls dead on the spot will taste the same as one who runs for 2 miles, and is shot at again during those 2 miles?
Do you think a mule deer will taste the same during the rut in Nov, as one in Aug before hunting seasons start?
And the answer to all of these is \"Yes\". I do not think there is any evidence that apples or any other macro-nutrient influences meat taste (except the exception above, fish oil, which really changes metabolism) above and beyond simply the amount of calories. The only thing I really could say about nutrition and flavor is that I believe that animals eating higher amounts of simpler carbohydrates (corn) will have more marbling, and therefore taste better. But animals in the wild can do that, too. (Your berry-eating bear, for example, is fed on simple sugars).
The trouble with other correlations is this: bias. We humans don\'t realize that we are so influenced, but we are. We see what we expect to see, and we don\'t see what we expect not to see. The same is true with taste, smell, etc.
The worst whitetail I ever shot was a corn-fed button buck shot in January in the snow, and dead in <5 seconds. One of the best was a rutting 170-class buck that was hit 5 times with muzzleloader shots as it traveled over a mile. I\'ve had the unfortunate chance to eat quite a few animals shot poorly and recovered quite some distance from their original position, and I can\'t say I notice anything different about them. (But had I been biased to believe that there was a difference, I too would taste something \"bad\" with them. But that\'s psychology, and I don\'t think it\'d hold up to a blinded test.)
When we experience bad meat, we can\'t resist the urge to associate that with SOMETHING. So, we find a correlation. Maybe it was gut-shot, or maybe it was a time-of-year thing. That\'s not much more scientific than the old Monty Python \"She\'s a witch!\" scene in Holy Grail.
Personally, I suspect a porcupine shot near the dump and one shot in the woods and even one fed Cheerios for a month taste the same: bad. Kobe beef tastes good because they are over-fed with carbohydrates (which leads to marbling) and have restricted movement.
