An ideal energy source for animals at risk of ketosis in cattle and twin lamb disease in sheep. No other supplement contains the four constituents of sodium propionate, niacin, sylibum marianum, (the active ingredient in milk thistle) and monopropylene glycol, making it more effective than propylene glycol only products. Niacin and sylibum marianum help break the energy deficiency cycle and speed recovery. Low volume, once a day dosage ensures ease of administration and less stress on the animal.
