OK, I can't remember where I read about it originally (probably some post on SB years ago), so I did some searching.

For those who are in tl;dr mode: Proton-antiproton reactions generate pions as a result, rather than the straight photons of electron-antielectron reactions. About 50% of proton-antiproton annihilation energy is 'lost' as neutrinos, due to the pion decay sequence.
