Concept of some more livestock!!
All of them, of course, are harvested for their blood, milk, pelts, meat, and bone, but some offer more highly valued product by quality and quantity.
Runt Livestock - valued most for their "eggs", a mutation in their ovaries has cause some of those dormant eggs to get engorged like a pimple, but instead of puss it’s a unique mix of proteins and fats, resembling yolk. These inflated eggs get rejected by the ovaries and forced into the unused uterus, collecting until it basically starts to trigger contractions to expel what is essentially a hoard of tumors. A cycle of their bodies endlessly growing and expelling red, squishy, mildly transparent, delicious, cancerous tumors. Their meat is very soft and their milk sour, used mostly for strong cheeses. They can choose to nest anywhere, no matter how inconvenient, they'll defend those spots like their life depends on it, even if those spots are on the backs of bigger livestock, butchee livestock often being the target, which unfortunately leaves their fur matted in blood and sticky eggs.
Worker Livestock - valued most for their accessibility. Even the most youngest and weakest of colonies are able to alter one of their own into the role of livestock (knowlege of the most advanced engineering and sciences are instinct to all mites, even if they aren't consciously aware of it. This skill is another reason they're regarded as ancient-bioweapons to many of the galaxy). They can still contribute to a colony as fellow worker (many who didn't get a choice in becoming livestock are often the ones who live as workers) but their creation is intended to be fed, pampered, milked, drained and harvested over and over again, their regeneration keeping this cycle going for as long as the livestock is still kicking, the moment they are brain dead from the pampered life, they are harvested COMPLETELY.
Soldier Livestock - valued most for their leather, blood, and bone. Their meat is the tough, their milk in particularly low supply and bland, but their blood - practically an aggressive drug that mites use as a stimulant before or during combat. Their leather often used for common mite attire and even armor, their bone also being quiet the valuable material for its ability to withstand insane levels of force. Aside from their product, they are utilized especially as guardian and draft animals (despite still being v e r y sapient), guarding livestock, pulling heavy carts, and being ridden into battle. Though all mites of any caste - including those not livestock - are also used as draft animals, soldier livestock is preferred due to their ability to work and run for days non-stop, pain or anger only making them that much more rabid compared to the average soldier.
Butcher Livestock - Valued most for their rarity and IMMENSE quantity in product. The sign of a powerful colony that is capable of feeding a butcher enough to be livestocked, their soft coat, and damn near adamantine tusks add to their value. Their meat is the toughest of all variants, but the most juiciest teaming with so much flavor that consuming it raw still brings satisfaction. Their milk is extraordinarily nutritious and sourced in such large quantities its often fed to other livestock. Now, their bones, they're not only an especially valuable material, but their bone marrow is to die for, and many do! Harvesting butchers are always bountiful, the only possible downside being their inactivity, always sleeping if not searching for new places to sleep. This inactivity, unfortunately, has made them content to neglect their coats, farmers needing to keep them clean and groomed, ESPECIALLY when runt livestock enjoy matting the sleeping butcher's coats with their sticky eggs and fluids.
