Free‐choice Feeding
Cattle, sheep and goats tend to self‐regulate free‐choice consumption of Thorvin to levels consistent with recommended rates. In some cases, animals will consume larger than normal quantities, but this binge typically only lasts 30‐60 days, depending on the animal’s mineral status. If higher consumption continues beyond 60 days, mix Thorvin with salt, one‐to‐one, to reduce intake, and consult your nutritionist. When feeding Thorvin free‐choice, provide one covered mineral feeder* for every 25‐30 cows and every 40‐50 sheep or goats. Also make sure animals have access to salt and clean water.
* For cattle: The classic blue Thorvin Mineral Feeder is 30 inches in diameter and 12 inches tall and weighs 40 lbs. The feeder has two compartments and holds 100 lbs. of Thorvin for Animals. The flap on top protects the contents and promotes longer usage. The unit can be anchored for additional security. For more info, contact Thorvin.
