Calculate doses for the following:

• 2 ounce chick
• 7 ounce chick
• 1 pound bird
• 10 pound bird

-Kathy

More conversions needed to get from ounces and pounds to mg/g/kg:

1 kilogram (kg) = 1000 grams (g) = 1000000 milligrams (mg) ( multiply kilograms by 1,000 to get grams or multiply 1,000,000 to get milligrams)

1 ounce (oz) = 28349.52 mg or 28.34952 g or 0.02835 kg (divide 28349.52 milligrams by 1,000 to get grams or divide by 1,000,000 to get kilograms)

1 pound (lb) = 16 oz

Lets first calculate bird weight in kilograms using the formulas above:

2 ounce chick = 0.02835 kg x 2 oz = 0.056 kg

7 ounce chick = 0.02835 kg x 200 oz = 0.19845 kg

1 pound bird (1 lb is 16 oz) = 0.02835 kg x 16 oz = 0.4536 kg

10 pound bird (10 lb x 16 oz = 160 oz) =  0.02835 kg x 160 oz  = 4.536 kg

Now for the amprolium at 20 mg per kilogram of bird. Easy... now you just multiply 20 times the bird weight in kilograms:

2 ounce chick = 20mg x 0.056 kg = 1.12 mg of amprolium

7 ounce chick = 20mg x 0.19845 kg = 3.969 mg of amprolium

1 pound bird = 20mg x .4536 kg = 9.072 mg of amprolium

10 pound bird = 20mg x 4.536 kg = 90.72 mg of amprolium

So how many ml's for each?

I was just starting to work on that before I saw you post this very question. As it dawned on me that someone reading that would confuse mg and ml.

Measuring 9.6% amprolium in mg = 0.096 mg x 1000 = 96g which is equal to 96ml (equal density 1 to 1 water mass/volume weight conversion). then the amount of amprolium in each dose in milliliters is...

2 ounce chick = dose of 1.12 mg of amprolium = 1.12mg divided by 96g = 0.011667g or 0.012ml

7 ounce chick = 3.969 mg dose of amprolium = 113.4 mg divided 96g = 0.041344g or 0.04ml

1 pound bird = 9.072 mg of amprolium = 9.072 mg divided by 96g = 0.0945g or 0.095ml

10 pound bird = 90.72 mg of amprolium 90.72 mg divided by 96g = 0.945g or 0.95ml

Ok figured out where I went wrong the first time and corrected it  .

Calculate doses for the following:

• 2 ounce chick
• 7 ounce chick
• 1 pound bird
• 10 pound bird

-Kathy

Edited to change 200 ounce to 7 ounce

The formula I use is weight of bird in kg, times number of mg per kg, divide by number of mg per ml = number of ml to give.

2 ounces is 56.6990463 grams, so I round up to 57 grams. 57 grams is 0.057 kg, the liquid has 96 mg  amprolium per ml, so it's

0.057 x 20 ÷ 96  = 0.011875 ml and I round up to 0.12 ml.

7 ounces is 198.447 grams, so I round up to 200 grams. 200 grams is 0.2kg.

0.2 x 20 ÷ 96 = 0.04166666666 ml - round up to 0.042 ml

For pounds I divide the pound by 2.2 to convert to kg.

1 pound bird -  1 ÷ 2.2 x 20 ÷ 96 = 0.09469696969 - round up to 0.095 ml

10 pound bird -  10 ÷ 2.2 x 20 ÷ 96 = 0.94696969697 - round up to 0.95 ml

• One gallon at the 0.024% level = ??? mg
• One gallon at the 0.012% level = ??? mg
• One gallon at the 0.006% level = ??? mg

-Kathy

Using these formulas to convert from ounces to milliliters to grams for each of the 3 solutions:

1oz = 29.5735ml = 29.5735g

16oz = 473.176ml = 473.176g

8oz = 236.588ml = 236.588g

4oz = 118.294ml = 118.294g

0.024%: 16oz amp/50 gal = 473.176g divided by 50gal = 9.46352g per gallon

0.012%: 8oz amp/50 gal = 236.588g divided by 50gal = 4.73176g per gallon

0.006%: 4oz amp/50 gal = 118.294g divided by 50gal = 2.36588g per gallon

Next convert g/gal back to milligrams by multiplying by 1000 (shown in to formulas below).

Then find out how much amprolium there is in each gallon of solution. Convert the 9.6% amprolium into a decimal by moving two decimal places to the left (0.096). Then multiply by the amount in milligrams of each solution.

0.024%: 9463.52mg x 0.096 = 908.49792 mg amprolium in one gallon

0.012%: 4731.76mg x 0.096 = 454.24896 mg amprolium in one gallon

0.006%: 2365.88mg x 0.096 = 227.12448 mg amprolium in one gallon

Should be correct this time  .

My brain is getting dizzy. I got to run to the feed store so I'll try again when I return. Maybe another member could give it a whirl before I get back.
