Pork: It's Not Just Used For Food

By Lianne Derocco


While the animals raised at hog farms are used mainly as a source of food for people around the world, this is certainly not the only benefit derived from these animals. Their parts are used in many helpful and interesting ways. Here are just a few uses for hogs that go beyond the dinner table.

There are many pig byproducts that are used to create medicines such as insulin and heparin. The latter prevents blood clots, and one of its ingredients comes from pig intestine. Pig tissue can be used in many surgeries, such as a skin graft surgery or perhaps ulcer surgery, and many doctors have found that there is far less allergic reaction with pig tissue than with human tissue. Pig heart valves also are similar to human valves and can be used in valve replacement surgery.

When you think of pigskin, you might think of footballs. These items are no longer made from pigskin, but there are many other products created with the skin of pigs, including leather for clothing and horse saddles. Tons of products you use throughout the year contain pig parts, from antifreeze to weed killer to chalk and paint. Floor wax, plastics and adhesives contain hog parts, and even some brands of shampoo and cosmetics.

Of course, hogs also produce a great deal of agricultural waste or manure. If the manure is carefully maintained, it also can be used as a fertilizer. Using an agricultural waste product such as the Agra Sphere can be an easy, safe and natural way to improve the overall value of nutrients in the manure. This product contains safe proprietary microbial isolates which work to prevent crusting, foaming and to keep the nitrogen levels under control. There is an Agra Sphere designed specifically for lagoon waste systems and another designed for deep pit containment.

Not only will the nutrient value be improved, the Agra Spheres also reduce flies and odors, as well as preventing harmful crusting and excessive amounts of sludge. These products are simple to use, making them an easy swine waste management tool. You just toss them into the containment system or lagoon, and they will begin to biodegrade and continuously released microbes into the waste.

Currently, there are many scientists working to create bio-fuel out of pig manure. While this is clearly not utilized as a mainstream product, it may be in the coming decades. One group at Duke University has produced a system where methane gas from pig waste is harnessed and then used to generate electricity.
