I have different thoughts on salt licks. Although some say they are necessary they are not dangerous (although true katnip, heart conditions you don’t want to be messing around with salt licks!)
But all livestock who are grazers require access to salt licks. Horses and cows must have salt blocks. They use them only when needed. They hypothalamus regulates cravings for food, and when you need salt you look for salt. If they don’t need them they won’t use them.
Sooo I offer them. Chuck uses his from time to time, Rupert and kahlua barely touch theirs. Most at the shelter do not use them, but some do seem to need them sometimes-especially the bigger hay eaters.
The pellets we feed are supposed to have salt contents in them, and they should provide enough. But grazers will use salt if it’s necessary and that’s why I prefer to offer them.
