High levels of copper, up to 250 ppm, are commonly used as a growth promoter in animal feed. However, excessive copper can negatively affect pork quality by making the fat softer. This is due to an increase in unsaturated fatty acids and muscle copper content, which raises the risk of lipid oxidation and leads to off-flavors or stale taste in the meat. On the other hand, copper plays a vital role in the body's antioxidant defense system as a cofactor for superoxide dismutase, helping to neutralize free radicals. To balance these effects, it is recommended to use organic forms of copper in pig diets, which provide the necessary benefits without the negative consequences associated with inorganic sources. Iron is a key component of hemoglobin and myoglobin, both of which are essential for oxygen transport and muscle function, directly influencing meat color. It also acts as a cofactor for catalase, an important enzyme in the antioxidant system that helps prevent lipid oxidation and maintain meat quality. However, high levels of heme iron may promote lipid peroxidation, which can degrade meat texture and flavor. Therefore, it's advisable to regulate iron levels in the diet and prefer organic iron sources to optimize health and meat quality while minimizing potential drawbacks. Chromium is an essential trace mineral for pigs, offering multiple benefits in swine nutrition. Adding chromium to finishing diets can help pigs better cope with heat stress, improve lean meat yield, daily weight gain, and feed efficiency, while also reducing body fat. As part of the glucose tolerance factor (GTF), chromium enhances insulin sensitivity, supporting metabolic health. Chromium supplementation is especially beneficial during transport and pre-slaughter, reducing the occurrence of PSE (Pale, Soft, Exudative) and DFD (Dark, Firm, Dry) meat. It also improves carcass composition, increases lean meat percentage, and reduces abdominal fat. Organic forms such as chromium picolinate, yeast-bound chromium, and chromium methionine are most commonly used in modern swine feeding programs. Selenium is a critical component of the antioxidant enzyme glutathione peroxidase (GSH-Px), which protects cells from oxidative damage by removing harmful peroxides. GSH-Px works synergistically with vitamin E to preserve cell membrane integrity and prevent lipid oxidation. Supplementing pig diets with organic selenium has been shown to reduce meat drip loss and enhance meat tenderness. In addition, zinc and manganese also play roles in activating superoxide dismutase, further supporting the antioxidant system. Increasing dietary levels of these minerals can help prevent the formation of PSE pork, contributing to better meat quality and overall animal performance.
