Anyway, I hadn't thought of saying *vighro'ghu*, *ngavyaw'ghu*, *qovIjghu*, or *bo'Deghghu* before. I remembered reading that -Hom was the standard way to name the young of animals (on this mailing list, I believe). -Hom creates some problems, though: if *SarghHom* is "foal", then how do you say "pony"? I don't know what all of you think, but I think a *SarghHom* would be a pony and a *Sarghghu* would be a foal.
Then we have KLV Klingon/Standard Vocabulary - KLV, which uses *SarghHom* for "donkey".
