If you are using Anthelcide EQ paste, which contains 22.7%
oxibendazole, and if your vet has authorized a basic dosage of 10
mg of oxibendazole per kg of rabbit, take the rabbit's weight in
pounds and multiply by 0.02 to get cc (or ml) of paste.

Volume of paste (cc) = Rabbit's weight in pounds x 0.02

Details:
Say the rabbit weighs P pounds.
First, calculate his weight in kilograms, using a conversion
factor of 1 lb = 454 g, or 1 lb = 0.454 kg
Weight in kg = P lb x 0.454 kg/lb
= (P x 0.454) kg
Then the weight of oxi in mg that he should get is
Weight of oxi = (P x 0.454) kg x 10 mg/kg
= (P x 4.54) mg
As the Anthelcide EQ paste contains 22.7% oxi, the weight of
paste in mg that he should get is
Weight of paste = [(P x 4.54)/0.227] mg
= (P x 20) mg
This weight of paste expressed in grams is
Weight in grams = (P x 20) mg x 0.001 g/mg
= (P x 0.02) g
Finally, assuming 1 cc weighs 1 g, the volume of paste in cc is
Volume of paste = (P x 0.02) g x 1 cc/g
= (P x 0.02) cc
The step called "Weight of paste" above shows why the company
making the paste chose that funny percentage of 22.7%. It's
because 22.7 divides exactly into 454, to give a round number of
20.
Note: The above calculation corresponds to the info given on the
Anthelcide EQ box, which says that for a horse of 1200 lb, you
give paste to the syringe mark of 1200; that's the entire tube,
or 24 grams, or 0.02 cc of paste per pound of horse.
