High levels of copper, up to 250 ppm, have been widely used as a growth promoter in livestock production. However, excessive copper can negatively impact pork quality by making the fat softer. This occurs due to increased levels of unsaturated fatty acids and muscle copper, which accelerate lipid oxidation and may lead to off-flavors or rancidity. Despite these drawbacks, copper is also a vital cofactor for superoxide dismutase, an essential enzyme in the body's antioxidant defense system that helps neutralize harmful free radicals. Therefore, it is advisable to use organic forms of copper in pig diets to balance its benefits and minimize potential risks. Iron plays a crucial role in the formation of hemoglobin and myoglobin, which are responsible for the color of meat. It is also a cofactor for catalase, another important antioxidant enzyme that helps prevent lipid oxidation and maintain meat freshness. However, high levels of heme iron may actually promote lipid peroxidation, potentially affecting meat quality. To avoid this, the iron content in feed should be carefully managed, and organic iron sources are often preferred to ensure better absorption and reduced oxidative stress. Chromium is an essential trace mineral for pigs, with multiple benefits in swine nutrition. Adding chromium to fattening pig diets not only helps them resist heat stress but also enhances lean meat yield, daily weight gain, and feed efficiency while reducing body fat. As a key component of the glucose tolerance factor (GTF), chromium boosts insulin activity, supporting better metabolic function. Chromium supplementation has also been shown to reduce stress-related issues during transport and slaughter, lowering the occurrence of PSE (pale, soft, exudative) and DFD (dark, firm, dry) meats—especially in more sensitive or hyperactive pigs. Using organic forms like chromium picolinate or yeast-bound chromium ensures better bioavailability and effectiveness in improving carcass quality. Selenium is a critical component of the antioxidant enzyme glutathione peroxidase (GSH-Px), which helps remove harmful peroxides from cells and protect lipids from oxidative damage. GSH-Px works synergistically with vitamin E to preserve cell membrane integrity and prevent cellular damage. Organic selenium added to pig diets can significantly reduce meat drip loss and improve meat tenderness. In addition, zinc and manganese act as activators of superoxide dismutase, and increasing their levels in the diet can further help prevent the formation of PSE pork. Ensuring adequate intake of these minerals through balanced and bioavailable sources is essential for maintaining both animal health and meat quality.
