How many cc give 300 lb calf?

You can't determine how many "cc" a 300 lb calf needs based on weight alone. "Cc" usually refers to cubic centimeters, which is a unit of volume.

Here's why you need more information:

* What are you measuring? "Cc" could refer to a volume of medication, a volume of fluid, or something else entirely.

* What is the purpose? Are you trying to figure out how much medicine to give the calf, how much water it needs, or something else?

To get the right answer, you need to be specific about what you're asking. For example:

* How many cc of antibiotics should I give a 300 lb calf? (This would require knowing the specific antibiotic, its dosage, and the calf's health status.)

* How many cc of water should I give a 300 lb calf? (This would depend on the calf's age, health, and the climate.)

It's important to consult with a veterinarian for any medical decisions regarding your calf. They can provide you with the correct dosage and advice based on the calf's individual needs.
