Salt, along with other minerals, is necessary to sustain life in cattle. Much like with humans, they are essential building blocks for living beings to perform at their best. It is needed for the body to perform even the most basic of functions.
The interesting thing about salt is that cattle have a natural “urge” for it. This urge means that they will actually seek it out, unlike the other minerals. If they cannot find it, they will try to ingest it from different sources, such as tree bark, dirt, and even urine.
As mentioned earlier, salt is essential to the overall function of a cow. Along with aiding with milk production, it will assist with other functions. These functions are reproduction, blood flow, and even sweating (which should be obvious).
