Dosages and Information Chart for calories, calcium, vitamin D and more.
WTgr (lb) | SCLcm (in) | Cals | Ca dose,mg | Vit D dose, IU
50 (2oz) | 6.4 (2.5â€Â)* | 6 | 10.8 - 19 | 10 - 100
100 (4oz) | 8 (3.2â€Â)* | 12 | 21.6 - 36 | 20 - 200
250 (8oz) | 11 (4.3â€Â) | 20 | 36 - 60 | 50 – 5,000
500 (1lb) | 13.8 (5.4â€Â) | 32 | 57.6 – 96 | 100 - 1,000
750 (1.5lb) | 15.8 (6.2â€Â) | 48 | 86.4 – 144 | 150 – 1,500
1,000 (2lb) | 17.4 (6.9â€Â) | 64 |115.2 – 192 | 200 – 2,000
2,500 (5lb) | 23.6 (9.3â€Â) | 107 | 192.6 – 321 | 500 – 5,000
5,000 (11lb) | 29.7 (11.7â€Â) | 214 | 385.2 – 642 | 1,000 – 10k
7,500 (16.5) | 34 (13.4â€Â) | 290 | 522 - 870 | 1,500 – 15k
10,000 (22) | 37.4 (14.7â€Â) | 360 | 648 – 1080 | 2,000 – 20k
50,000 (110) | 64 (25â€Â) | 1200 | 2,165 - 3600 | 10k - 100k
WT- Tortoise’s weight in grams and (ounces or pounds).
SCL- The minimum recommended Straight-line Carapace Length for the weight, according to Dr. Susan Donohue’s formula of SCLcm^3 x 0.191 = mWTgr, presented in centimeters and (inches). [Pingleton]
*= Note- The SCL formula is not considered as accurate for very young tortoises.
Cals- Recommended daily calories for active reptiles, per the formula WTkg^0.75 x 32 (x2 for active tortoises) [Mader]
Ca- Daily recommended calcium dosage range based on the formula 1.8 to 3mg/kcal [Mader]
Vit D dosage range, based on 200-2000IU/kg/day [Mader]
To calculate other nutrients [Mader]:
- Phosphorous levels- for a Ca: P of 2:1, aim for ½ of the calcium level.
- Vitamins A and E- use the vitamin D dose as a base. Multiply by 10 for the A dosage, and divide by 10 for the E dosage to make a ratio of A/D/E of about 100:10:1
- Fat to Proteins to Carbohydrates levels- % of calories-
---- For herbivores (grassland and desert species): 5% fat – 20% proteins – 75% carbohydrates
---- For omnivores (forest species): 25% fat – 25% protein – 50% carbohydrates
---- 1 gram of fat is 9 calories, 1 gram of protein is 4 calories, and 1 gram of carbs is 4 calories.
---- 100 calories for a herbivore should be about 1/2g of fat, 5g of protein, and 19g of carbs.
---- 100 calories for an omnivore should be about 2.5g of fat, 6g of protein, and 12g of carbs.

This may be my geekiest post yet! I want to clean it up to a full article but I'd like to find a better way to format the chart and make it easier to understand.
So, my questions to you, my faithful friends, are...
1. Does it make sense. If not, what is confusing you?
2. Any ideas on doing a nice chart?
3. Would you like more information, documentation, etc.?
4. What would be a better way to present the amounts of fats, proteins, and carbs in the diet- just adding it to the chart maybe?
5. Would you want the phosphorous, A and E levels added as well? I think it would just make for a messier chart, but I can add them if you want.
