Unique meat/nutrition system for carni's

Different kinds of meat give different growbuffs/nutrition bonuses. In example: eating Stegosaurus meat gives a bigger growth then eating meat from the same species as you (cannibalism). Harder to kill targets (Eotriceratops, Stegosaurus, ... ) give overall more growth then easy targets like Struthi or other carnivour species. Maybe even implement poisoned food for Mega and Metri so if they die or eat something, that meat gets poisoned. Each carnivore should have his own ideal prey species, wich gives the biggest growth and or quest, this will make players want to group up and target/hunt a particular species.

I think the game would benefit from this because it:
-Encourages same species pack hunting.
-Discourages cannibalism and carnivore on carnivore killing.
-Encourages herding for herbivores.
-New way of growing.
-Encourages exploring to hunt.
-Unique addition to ecosystem.

Im sure we can work this out more and better. Feel free to think about the pro's and cons of this system.
