This is a topic I've seen mentioned in the forums a few times before, and decided not to comment (for I've thought that this will be discussed again, once the need to feed livestock gets implemented in the game). So, not going to go into details of this discussion now, when plans for "the need to feed livestock" are just that - plans, and not yet in the works. Just a short mention, one point:
As a person living in the countryside, with decades of first-hand experience in feeding domestic animals like horses, cows and sheep, and as a person who has read something about the history of animal-rearing in Finland, and also has first-hand experience about the old traditional breeds like the Finnhorse and Finncattle, I'd like to make a point: "hay for food, straw for bedding" is a relatively modern invention. 1000 years ago it was more like "feed your animals with what ever you managed to gather in the summer", which meant things like dried bunches of broadleaved saplings, moss, straw, and yes - wild hay. (For bedding it was most likely peat and moss).
I've seen my own Finnhorses deliberately choosing to eat straw when hay is also available. Those old breeds have digestion all geared towards survival, they like to chew tree bark etc. Finncattle digestion is more like a reindeer, than a modern cow bred for maximum milk production.
Oh well. And in case someone disagrees and feels a need to continue this discussion, please do so in "general" or "off-topic" sections instead of dev.news which is for announcing features Sami is working on, not about going into details discussing future plans.
