How to Use This Calculator

Enter Bird weight (grams), Medication, and Drug concentration (mg/mL).
Set Doses per day.
Review Dose per administration (mg) and Volume per dose (mL).
Use Total daily dose (mg) and Total daily volume (mL) to inform your decision.

How the result changes with Bird weight (grams)

Bird weight (grams)	Dose per administration (mg)	Volume per dose (mL)
5,005	75.08	7.51
17,503	262.55	26.26
32,502	487.53	48.75
45,001	675.02	67.5

What each input means

Bird weight (grams): Body weight in grams. Budgerigar ~35g, Cockatiel ~90g, Amazon parrot ~400g, Macaw ~1000g.
Medication: 0 = Enrofloxacin (15 mg/kg), 1 = Meloxicam (0.5 mg/kg), 2 = Doxycycline (25 mg/kg), 3 = Metronidazole (25 mg/kg), 4 = Itraconazole (10 mg/kg), 5 = Butorphanol (2 mg/kg).
Drug concentration (mg/mL): Concentration of the drug solution or suspension in mg per mL.
Doses per day: Dosing frequency: SID = 1, BID = 2, TID = 3.

What each result means

Dose per administration (mg): Amount of drug in milligrams per single dose.
Volume per dose (mL): Volume of drug solution to administer per dose.
Total daily dose (mg): Total milligrams administered per day across all doses.
Total daily volume (mL): Total volume of drug solution per day.
Dose rate (mg/kg): Standard dose rate for the selected medication.
Est. BMR (kcal/day): Estimated basal metabolic rate using allometric scaling (non-passerine).

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Bird weight (grams) = 400, Medication = 0, Drug concentration (mg/mL) = 10, Doses per day = 2 = 4 input(s) provided
Calculate Dose per administration
Dose per administration = selected.mgPerKg * weightKg
6 = 6
Calculate Volume per dose
Volume per dose = dosePerAdminMg / concentrationMgPerMl
0.6 = 0.6
Calculate Total daily dose
Total daily dose = dosePerAdminMg * frequencyPerDay
12 = 12
Calculate Total daily volume
Total daily volume = volumePerDoseMl * frequencyPerDay
1.2 = 1.2
