) Keto-Nia Drench is an energy and vitamin supplement for use in fresh cows, sheep, and goats. It contains propylene glycol, niacin, and certain vitamins to help maintain normal energy and vitamin levels at freshening. Cattle: provide 200 ml orally with a drench gun at the first sign of freshening; repeat 6 to 12 hours post calving. Sheep/goats: provide 1 oz. at the first sign of kidding; repeat 6 to 12 hours after kidding. If the first feeding is missed, a post delivery feeding is still beneficial.
