The body uses zinc to process food and nutrients. When animals do not have enough zinc in their systems, they need to consume 50% more food to match the weight gain of an animal with enough zinc in its body. About 0.003% zinc is needed for proper health. Zinc is relatively non-reactive in air or water. Consequently, it is applied in …
