![]() ![]() Major absorption of calcium takes place in the duodenum. 99% of Ca and 80% of P in the organism are found in bones and teeth. Minerals in this group include calcium, phosphorus, magnesium, potassium, sodium, chlorine and sulfur.Ĭa and P, which make up 70% of the total amount of minerals in the body, are usually examined together. On the contrary, the absorption percentages of divalent cations (Ca, Mg and Zn) are quite low. For example, monovalent cations (K and Na) have high absorption properties and there are important relationships between each other. Such useful classifications describe the physical and chemical properties of the mineral in feed. Apart from these, they are classified on the basis of their valence numbers and their positions in the periodic table of atoms. Macro and Minerals Essential for Livestock are also classified as cations (Ca, Mg, K, Na, Fe, Mn, and Zn) and anions or those in the anionic group (Cl, I, Phosphate PO4, Molybdate MoO4). However, it is known that Cr, Co, Cu, I, Fe, Mn, Mo, Se, and Zn are essential for all animal species. Minerals that are absolutely necessary to be taken with tests made on at least one animal species It has been demonstrated by tests that some of the microminerals reported in this chart are essential for only some animal species. There are 24 minerals needed by various animal species, in other words exogenous. Macro minerals are expressed as a percentage of the ration, microminerals as ppm or sometimes ppb. On the other hand, those that are above 50 ppm (mg/kg) per kilogram of lean body weight are defined as macrominerals and those that are found in lower amounts are defined as microminerals. Those required below this amount are called microminerals (trace minerals). ![]() In this context, those that require more than 100 ppm (parts per million) are called macrominerals. Minerals needed in high amounts are called macro minerals, whereas those needed in low amounts are called micro minerals (trace minerals). This single premix can be used in diets for all stages of production by adjusting the inclusion rate for sow, nursery, grower, and finisher diets.Ī sow add pack is also available for sow diets to supply the specific vitamins to enhance reproduction.The chart of classification of minerals is helpful in determining the nutritional role of these elements. Otherwise, VTM premix age must be monitored to ensure it is used before excess vitamin loss.įact Sheet: Mineral Sources for Swine DietsĪ suggested trace mineral premix is available at KSU Premix & Diet Recommendations. Trace minerals can be combined with vitamins in a VTM premix, but it is recommended to have separate premixes because trace minerals can affect the vitamin stability. ![]() In sow diets, a sow add pack is also included to supply the specific vitamins to enhance reproduction. This single premix can be used in diets for all stages of production by adjusting the inclusion rate for sow, nursery, grower, and finisher diets. Consequently, it is essential to balance the diets using supplemental mineral sources to meet the requirements.Ī suggested trace mineral premix is available at KSU Premix & Diet Recommendations. However, the intrinsic minerals are often found at low concentration and availability in feedstuffs is questionable. Grains and oilseeds commonly used in swine diets are sources of macrominerals and trace minerals. The requirements for and dietary concentrations of macrominerals are generally expressed as a percentage (%) of the diet, whereas microminerals are expressed as parts per million (ppm or mg/kg) or milligrams per pound (mg/lb) of diet. Chromium is also sometimes added to sow and finisher diets to improve performance. Microminerals or trace minerals need to be supplied in smaller amounts in swine diets, as is the case of zinc, copper, iron, manganese, iodine, and selenium. Macrominerals or major minerals need to be supplied in larger amounts in swine diets, as is the case of calcium, phosphorus, sodium, chlorine, magnesium, and potassium. Minerals are classified into macrominerals and microminerals according to the amount required in the diet. The mineral nutrition of pigs must be precise because adding excess minerals to the diet can be costly and cause toxicity while not providing enough minerals can result in deficiency and reduce productivity. Functions of minerals are extremely diverse, serving a variety of structural, metabolic, and regulatory functions in all body components. Minerals constitute a small percentage of swine diets, but their importance cannot be over-emphasized.
