My cows lactate oil instead of milk, how do I stop them from igniting?
Starting off, these domesticated herbivores, much like cows, exist on a terrestrial world 15-20% larger than Earth. With a higher gravity of 11.2 G, Earth-like atmosphere, and if it existed in our solar system, would be positioned behind Earth like Mars but 1.5 AU from the Sun rather than Mars 2.0 AU. Lastly, 38% of the surface is landmass. 255
I figure I provide this extra information if it helps at all.
These "dairy cattle" in my idea, partially for "economic balance" reasons relative to nothing in particular, produce 4 liters of oil in a 1-2 week timespan versus our cattle that produce 4 liters in a single day.
In one major part of this world, these oil-cattle are native and incredibly valuable specimens for the early industrialization of this mountainous continent. They're often the casus belli between large tribal kingdoms and city-states inhabiting these regions and the rising bourgeoisie are as much as oil-cattle barons as they're the new nobility.
My problem is, how do you prevent the ignition of their oil product? Human raiding since time immemorial would probably make them extinct if torches, farmstead fires, forest fires, black powder firearms would render them crispy.
Knowing nothing about oil even after reading numerous things, I came up with several possibilities, I hope?
-Petroleum Pasteurization? Farmsteads have minor refineries that render the oil usable for consumption perhaps. Even though these oil-cattle would need to nurse their calf, I guess their stomachs process oil just fine too.
-Instead of oil byproduct, these oil-cattle resemble Rimworlds Boomalopes, with large blubber sacs around their body, that can be fleeced like sheep wool periodically and then processed like Whaling in pots. I really like this idea, but regenerating blubber seems so hard to explain naturally even though this is science fiction.
-Their oil contains the nominal amount of hydrocarbons, but also large percentages of protein and fat that render the oil much harder to ignite between being in its body mass ready for lactation, and being pumped out.
Please help me, thanks. 1022
