However, minerals should not be added to the diet haphazardly. Overuse can lead to serious consequences, including antagonistic effects between minerals and medications. Mineral deficiencies are more likely to occur in swine than in other farm animals. Body stores of minerals are used in emergencies, but these are insufficient for maximum production. Pigs have a rapid growth rate.
Pigs reproduce at an early age while still reaching mature body weight.
Certain trace minerals may also be needed. Tables 1 and 2 show minimum and practical mineral requirements for growing and reproducing swine. Cu as CuSO 4 have been shown to improve growth performance. These two minerals must be considered together when calculating the total amount of each needed to meet the requirement. The ratio of calcium to phosphorus is important to ensure optimum performance.
