| Re: Should I put Vitamin C drops in Water or can I put Tang in the water? The only time supplements like Oxbow C tabs or other plain chewable vitamin C or a liquid C that you syringe directly to the pigs should be given is if the pigs won't eat veggies or they are ill and off their food or have scurvy. If a person provides 1 cup of fresh veggies per day containing enough C, they really won't need a supplement. |
