Salt, NaCl, of any kind does not melt at common temperatures.
It dissolves. Salt is slightly hygroscopic, that is it absorbs water from the air.
So a block of rock salt left in the field for the animals, will gradually dissolve from absorbing moisture. But moisture absorbed at the surface will be absorbed further into the block, thus lessening the dissolving at the surface.
Hopefully it dissolves much slower than the animals lick it.

How does salt make ice melt on roads?
Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 F (-6 C), and a 20-percent solution freezes at 2 F (-16 C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it. The saltdissolves into the liquid water in the ice and lowers its freezing point.
