Male and Female Orcs

(... from a later post...) Just a note– Alfirin, it's specifically the Isengarders who were crossbreeds, not Uruk-hai in general. Apologies if I sound pedantic here– it's just that this does have a bearing on this "unpublished manuscript" business– (...)

To add my pedantry, I would add the distinction that the Isengarders could be, as I think is the case, a mixed bunch: Uruk-hai (great soldier orcs) -- as well as Half-orcs (results of interbreeding).

The debate goes on, but my point is merely that Saruman's orcs need not be half-breeds -- these are aguably his Uruk-hai. And in general (not that anyone said otherwise) we don't necessarily need a hybrid to produce a larger orc, but selectively breeding larger orcs in general should do the trick.

At least there is an arguable distinction in the text concerning the half-orcs and the uruks (the half-orcs being taller for example, and some being man-like enough to serve as spies).

This is where the addition of human remains would be important to the creation of your "Man-Orc" or Uruk-Hai, but even this would take many generations. Maybe 20 years for five to ten generations, depending upon the quality of Orc wanted, the longer the time, the better the quality of Orc. So, Uruks would probably be four to five years per generation. That is still a very short time to breed Orcs, as a HUGE Army could be raised in relatively short times.

Also, many of the Orcs in a batch might not make it, or they might be cannibalized as food by those "Hatching" early.

Their cross-breeding with fungi allows them to reproduce asexually, which explains the lack of Ork females. This reproductive process basically involves the dispersion of spores from a decomposing Ork corpse, such that killing an Ork literally creates more Orks, explaining why Orks are such a difficult enemy to combat and how, along with their extreme physical hardiness, they can very easily infiltrate and build up large populations virtually anywhere. The only known solution to this problem is to incinerate the entire area to destroy all Orks and Ork spores. Because Orks are so genetically similar to plants and fungi, their diets are extremely flexible - Orks can be used not only as meat, but also as yeast and phytochemical-containing fibrous plantlike sides. Thus, Ork Pie is a staple of Ork diets, particularly on the battlefield, where little other food is available, and dead Orks are in abundance.
