Other than humane factors, how does the treatment of an animal affect the quality of the produce?

Answer 1

If animals are very stressed, they release hormones that make the meat not taste as good. For that reason, more humane slaughtering techniques have been developed to keep the animals relaxed and unaware of impending death.

And then for Kobe beef, the animals are massaged to get good marbling and to improve taste.

I understand that old milk cows, when slaughtered, produce beef that has less fat in it and that will affect the taste as well.
