how is that relevant?

> the animal was killed, so isn't it more respectful to use as much of it as possible

'respectful' - using that word about an animal you've killed is self-deceit. The animal is dead, and when it was alive it had no concept of 'respect'. Deluded talk.

I also don't get the point of your related aside. My post was about animal suffering, not use of the carcass so it looks like you're changing the subject.
