These are used to boost mineral, salt and energy content of the daily ration. They are especially important when feeding concentrates in a ‘straight’ form in order to provide a balanced ration.
Most commercially produced pellets and mixed feed are balanced for mineral and salt content thus making further additions unnecessary. In growing young stock it is important not to cause imbalances in the mineral content of feed by over-supplementation, especially important for the calcium/ phosphorus ratios. Imbalances can be very harmful to healthy growth and development.
