I’m not for a second justifying needless animal suffering, but you’re picking on the wrong thing, presumably due to a lack of understanding of the area under discussion. A solidly established concept in regulated animal trials (e.g. of human drugs in early development) is to prevent further suffering, once a line has been crossed, by way of killing the animal quickly and cleanly. It isn’t palatable but this fundamental concept, and the term ‘sacrifice’, aren’t issues here.
