Eat everything, aka the rule of rations

 Aka vilecult abuses math


An adventurer needs about 4000 calories a day. An iron rations contains this. Meat and carbs are the most energy dense. Plants have very little in the way of calories. You can't survive wild foraging plants.

Nuts are the most realistic food source. 4000 calories of acorn meat = 2.2 pounds. Plus it takes days to soak and dry the nuts to make them edible. But they're only available for about two months of the year.

It would take 20 pounds of berries to meet an adventurer's food needs. They'd have to eat the equivalent of fifteen potatoes in wild tubers. Just forget about salad - most leaves contain less calories than it takes to digest them.

So hunting it is. How much meat is in a wild animal?



This article has a lot of great info about this subject. I get all my numbers below from it.

A deer is about 40% meat. This doesn't include the guts, which you would definitely want to eat in a survival situation. In the article they say you can get close to the live weight of the deer by multiplying the field dressed weight by 1.28 - field dressing just means taking out the organs and blood. So if you have a 125 pound field dressed you've thrown away about 35 pounds of viable food.

So that's like, what, 60% of the deer is edible?


I'm pedantic enough to figure out how many iron rations are in a deer, but I'm not pedantic enough to figure out how many calories are in deer liver (885/lb) versus meat (675/lb).

Okay maybe I am.

Actually this is pretty easy. You can just multiply the organ meat weight by 885 and the venison weight by 675, add them together and divide by 4000.

But who wants to do that at the table? Let's just go with 60%. That's a nice clean number for our back of the napkin calculations.


Does weigh between 80-120 (average: 100)

So that's 60 pounds of meat *675 = ~40,000, divided by 4000, or 10 rations

Bucks between 120-160 (average: 140)

84 pounds of meat *675 = 56,700 calories or 14 rations

Beat that, vegans.



According to this chart most game animals have pretty close to the same number of calories per 3.5 oz portion. Close enough to our magic 675 above that I feel comfortable using that as the number of calories in all meat.

The thing is that different kinds of animals have different amount of meat on them. But we're not gonna do that, we're just gonna assume all animals follow the same ratio as deer. We actually want people to come back to our game.

Male alligator, 500 - 1000 (76 rations)

Reticulated python, 170 - 250 (21 rations)

Rattlesnake, 3 - 5 (5 rattlers make 2 rations)

Boa constrictor, 20 - 30 (2 rations)

Note on snakes: you could probably get more rations out of a snake. Might double it.

Female water buffalo, 400 - 700 (55 rations)

Male water buffalo, 600 - 1200 (91 rations)

Female bison, 800 - 1200 (100 rations)

Male bison, 1000 - 2200 (162 rations)

Domestic cow, 800 - 2400 (162 rations)

Domestic bull, 1000 - 4000 (253 rations)

Calf, 25 - 100 (6 rations)

Domestic sheep, 100 - 220 (16 rations)

Domestic sheep, 100 - 350 (22 rations)

Female giraffe, 1200 - 2600 (192 rations)

Male giraffe, 1800 - 4500 (318 rations)

Female elephant, 6000 - 8000 (708 rations)

Male elephant, 4000 - 14000 (911 rations)

Stegosaurus, 6800 - 11000 (901 rations)

Triceratops, 12000 - 16000 (1417 rations)

Ankylosaurus, 11000 - 18000 (1468 rations, but maybe less, they don't look like they've got much good meat on em)

Apatosaurus, 36000 - 49000 (4151 rations)

Argentinosaurus 110,000 - 220,000 (16,706 rations holy shit)

Tyrannosaurus, 11,000 - 15,500 (1341 rations)

Pteranodon, 55 (5 rations)

Quetzalcoatlus, 550 (55 rations)

You get the idea.


Do you have a faster way to calculate?

5 rations per 50 pounds

So how much do these meat rations weigh?

The magic meat number is 675 calories per pound, making a 4000 calorie fresh meat ration weigh 6 pounds. If its dried into jerky for iron rations it'll lose 2/3s its weight and be 2 pounds. Organ meats tend to lose more water but let's not be fussy.

How long does it take to butcher an animal?

It takes about 20 minutes to pluck and cut up a chicken. Rabbits are faster. It takes me about an hour to skin and butcher a deer. Several people working together on a cow might take a couple hours - we're using old fashioned bone saws at best, or knives. I estimate an hour per 500 pounds. This is mostly for palatability and for drying the meat. Nothing's stopping the party from indiscriminately hacking off chunks and roasting it.

How long does drying meat take?

You have to cut it into thin strips and hang it. That takes a long time, see above. Humidity has to be low or meat will spoil. 8-14 hours in the sun.

Smoking it?

Ideally you salt it first. 1 day per 10 rations.

Salt?

10% salt per weight. 10 rations = 60 pounds = 6 pounds salt.

What else?
