And they're not supposed to?
2010-04-07 19:41   
how exactly is this a bug?
2010-04-07 22:45   
Bringing entire barrels full of blood does not exactly seem like intended behavior. Seriously, I don't think it's even useful.
2010-04-08 00:48   
I don't think this is a bug. but you have a point. Why do they bring blood? Are we supposed to buy this blood? Why? What would we do with it? It doesn't seem to serve any function.

I suppose its no different than them bringing unusable plant extracts as trade goods. But then, that doesn't really make sense either.
2010-04-08 01:36   
Barrels of cow blood: ok I can understand that. It's when they bring barrels filled with monarch butterfly ichor that I start to wonder.
2010-04-08 01:40   
Perhaps this will be a more useful feature down the line, when things like alchemy and magic are working and require reagents, so I would imagine it's intended.
2010-04-08 06:51   
Perhaps there was a vampire fort just down the road.
2010-04-08 07:40   
Perhaps used for cooking? Its a valid item used in foodstuffs for a very long time in the real world.

That being said, I don't know if blood is marked properly as an edible / cooking enabled item, but the forum project to clean up the raws addresses this i think.
2010-04-08 08:19   
Same thing encountered here...
Klingon bloodwine anyone?:P
Maybe this can be worked into a feature by enabling kitchen/still to use blood(Some cuisine use (processed)blood for cooking, But I have no idea if blood has ever been used for alcohols in reality...)
If blood's ever going to be made into food...there are still bugs with cooking liquid AFAIK...
2010-04-08 09:57   
If we had some way of removing the blood from the barrel we could make a blood bath or other "interesting" features but as it stands its just takeing up space that beer could be taking.
2010-04-08 10:02   
@GauHelldragon: Yeah, I got barrels of firefly ichor with my first caravan. Must have been a small barrel, as there were only 10 units of the stuff (or each unit took hundreds of fireflies to get).
2010-04-23 15:14   
(edited on: 2010-04-23 15:15)
Considering the fact that there are actual RL recipes that use blood (like blood sausage for example)I also donĀ“t see it as bug.

At least getting blood as trade objects (I hope that it really can get used in meals...if not, I would rather consider this to be a bug ;) )

As for getting butterfly ichor...
well, considering the fact that we get other strange things like, for example, firefly brains and are able to turn them into meals, I assume it seems to be rather normal in the world of dwarf fortress

Likely because blood is considered an animal extract such as venom and milk.
2010-05-04 05:10   
As a workaround for emptying the barrels; forbid the blood, then have the barrel be taken to the trade depot. A dwarf should then move the barrel and leave the blood in the stockpile. I accidentally wasted a stockpile full of gnomeblight this way.
2013-04-18 17:41   
I'm reasonably certain, from hearing Toady speak about it in at least one podcast, that this is UNINTENDED behaviour, a result of these items being classified as foodstuffs. Alas, there is no [trade-exempt] tag to prevent these things from appearing in strange quantities (like the barrels full of insect brains), so the materials are collected, just like everything else.
2014-11-14 07:13   
There are pages of different blood available on embark.
Not bad as such, but could take some adjustments. Like making it uncommon for traders (without request) and a few applications in cooking/brewing.

Also, could vampires drink animal blood when it's available in barrels?
2015-03-09 14:25   
Heh I still get "liquid" from my caravans even in 0.40

2015-03-09 16:23   
Reminder sent to: Terff

The bringing 'liquid' bug wasn't fixed until 40.06 - are you using a more current version?
2017-11-26 13:05   
This stopped for blood without attached syndromes in 43.something, but has started up again in 44.01.
2017-11-28 21:51   

I don't recall blood barrels ever being blocked. Here's a trading-test save I created in v0.43.05; the dwarven caravan is offering barrels of hamster blood and wombat blood, among others:

Still present in 47.03, the only jobs that handle extracts from animals particularly are animal dissectors which as Quietust remarked in 0001044 c24799 the [USE_ANIMAL_PRODUCTS] not using robust enough checks.

Dwarves have precedent to trade cave spider venom because they can extract it using the 'Extract from a dead animal' job in conjunction with a vial from trapped living cave spiders (the job's name is incorrect in this regard, perhaps referring to vermin small remains). The job also processes & butchers creepy crawlers, as to redeem seemingly any usable material or asset from the living vermin item without any kind of specified target.
