Preferably not to use refined sugar, but honey (raw) is better. I have used the following.:
2taespoons of salt, 1 teaspoon baking soda (bicarb) and 8 tablespoons of honey to 1 (American - 3.5ltrs) of warm water.
Taken from Storey's Guide to Raising Goats. It worked. The say never to use cane sugar, but a raw form of natural sweetener.
