Good for you for doing the necropsy! It's not a pleasant task, but to me it's a lot better than sitting around trying to guess why the animal died.
How digested was the clump of grass? A good way to tell if it was blocking is to feel the intestines below the clump. Is there matter in there? If so, it probably wasn't blocking and just sort of stopped there when digestion ceased at the end of his life. Matter will evacuate the intestines in a couple of hours, so the contents of the lower intestines below the supposed blockage is a good measure of how severe it may have been.
Even if it was blocking then it would not have been a quick nor painless death. It would probably have taken a couple of days to kill him as toxins built up from the bowel blockage.
You mentioned the lymph nodes were larger than you expected. Do you have an accurate basis for measuring that? I mean, have you seen normal healthy goat lymph nodes? If the lymph nodes were indeed swollen it means he was fighting off some infection that probably killed him. The clump of grass was just a clump of grass in that case.
Finally, 12 weeks seems to be about the dying point for livestock. A lot of people feel that if you make it to the 6 week point then the animal is in good health, but I haven't found that to be the case with goats and sheep. At 3 months, the animal is entering puberty and subtle birth defects start to come into play as the growth rate rapidly accelerates. That's when the most mysterious deaths also happen. I suspect that a lot of those mystery deaths where the animal suddenly drops dead are due to aneuryisms and heart attacks.
We should realize that almost all of the livestock we know today were domesticated over 10,000 years ago. Since then all we've really done is create individual breeds and variations, not all of them to the benefit of the species. Since industrialization and the decline of our reliance on livestock, most of the breeding has been done haphazardly and with no eye towards improving the health of the species. There are all sorts of hidden time bombs lurking in the health of these animals that the casual eye could never detect.
