Much of the info on this page is obsolete because the grazing calculations were significantly changed in the 40.13 release. The description of the change was: "Reworked grazing formula, used fractional exponent to scale properly according to size."
In d_init.txt this was added:
Set this number to scale how often grazing animals need to eat. Larger numbers mean less food is necessary. Metabolism is always set according to the 3/4ths power of size.
[GRAZE_COEFFICIENT:100]
Further research is needed to determine what the pasture size needed for a given animal size.

- Toady posted the STANDARD_GRAZER formula in the FotF thread. It is 20000*G*(max size)^(-3/4), where G is the graze coefficient, and max size is the internal body size, so raw body size divided by 10. Knight Otu (talk) 18:18, 25 September 2014 (UTC)
Ok, that's helpful. Assuming G is normalized so that GRAZE_COEFFICIENT:100 means that G is 1.0, here are some sample animals:
| Animal | max size | New GRAZER | Old GRAZER |
|---|---|---|---|
| Rabbit | 50 | 106,366 | 120,000 |
| Sheep | 5000 | 3,364 | 1,200 |
| Alpaca | 7000 | 2613 | 857 |
| Donkey | 30000 | 877 | 200 |
| Cow | 60000 | 522 | 100 |
| Water Buffalo | 100000 | 356 | 60 |
| Elephant | 500000 | 106 | 12 |
Using the rule of thumb that 20000=Grazer*Required_tiles, then:
| Animal | New Tiles | New NxN | Old Tiles | Old NxN |
|---|---|---|---|---|
| Rabbit | 0.2 | 1x1 | 0.2 | 1x1 |
| Sheep | 6 | 2x3 | 17 | 4x4 |
| Alpaca | 8 | 3x3 | 25 | 5x5 |
| Donkey | 23 | 5x5 | 100 | 10x10 |
| Cow | 38 | 6x7 | 200 | 14x14 |
| Water Buffalo | 56 | 8x8 | 333 | 18x18 |
| Elephant | 188 | 14x14 | 1667 | 41x41 |
Those are significantly smaller for the larger animals, and look like they could be reasonable. I'll try reducing my pastures to the sizes based on this formula and see if they do OK. If so, I'll update the page with the new formula and values. Thanks for the info!
