AS143/AN143: Feeding Food Wastes to Swine
The feeding of food waste or garbage to swine and other livestock animals is a common practice throughout the world and is often concentrated around metropolitan centers. Food waste can be defined as any edible material or byproduct that is generated in the production, processing, transportation, distribution, or consumption of food. The primary waste products fed to swine are plate and kitchen waste, bakery waste, and food products from grocery stores. For the purpose of this article, the term food waste will be used to refer to all food wastes, including plate waste, kitchen or table scraps, garbage, or swill, and all food residuals discarded after serving. Feeding food waste to swine has been common in the United States, especially in rural areas adjacent to major metropolitan areas. It is the presence of meat in food waste that necessitates cooking; all table or plate scraps resulting from the handling, preparation, cooking, or consumption of food require cooking before feeding to swine. Texas, a leading food waste feeding state, has recently banned the feeding of food waste because of FMD. The recent outbreak of FMD in the UK originated on a “Food-waste-feeding” swine farm where contraband meat had been fed. When fed properly, food waste can be a nutritious food source for swine. Most swine fed exclusively on food/plate waste attain maximum gains of about one pound per day, but to achieve this, swine must consume food waste in larger quantities than they would commercial swine feed. These farms collected food waste from institutions and often supplemented with other food wastes such as bakery, fish cannery, or vegetable processing wastes. Development of new technologies to process food waste is a major need for food waste feeding. The variability of food waste composition highlights the difficulty in including food waste in contemporary swine diets. Some of the issues that will influence new processing techniques are regulatory in nature, such as whether processed food waste meets the requirements of the Swine Health Protection Act, or whether the Food and Drug Administration should regulate these processes. 1.01d. 1.36d. a Pigs given Treatment 1 received a corn and soybean-meal diet ad libitum; Treatment 2 received ad libitum food waste plus a corn premix limited to 50% of Treatment 1 intake; Treatment 3 received ad libitum food waste plus a corn premix limited to 25% of Treatment 1 intake; and Treatment 4 received only ad libitum food waste. The dietary treatments were formulated assuming protein needs would be met by food waste and energy would be limiting in food waste diets.
L-5392 10-02 Keeping Show Pigs Healthy Bruce Lawhorn Associate Professor and Extension Swine Veterinarian The Texas A&M University System how pigs can bring many disease organisms into a farm and spread them to other swine. You can take several steps to help prevent your show pigs from contracting and spreading diseases. The precautions include: S Remember: The greater the exposure, the greater the likelihood Take care that the pigs are healthy of disease problems. Use isolation practices to prevent dis- When buying show pigs, it is best to buy them directly from one farm of origin that has a history of excellent herd health. Provide rations containing medication to prevent specific diseases that kill or cripple pigs. Start with healthy pigs Isolate pigs coming from off the farm To prevent disease outbreaks in show pigs, start by preparing before you produce or buy them. If you buy show pigs directly from several farms, keep the pigs from each farm isolated in separate pens even while hauling them, and prevent them from contacting each other through the fence for 60 days. Follow good health management practices As a general rule, it is much easier to prevent swine diseases by using good management practices than to successfully treat the pigs after they have become sick. Treating healthy pigs with an injectable antibiotic in an attempt to prevent diseases as a result of poor management usually does not work! For example, if pigs are purchased from multiple sources, mixed on a trailer and subjected to the stress of hauling, injections of antibiotics during this time may only postpone or delay the development bacterial diseases. Vaccines are not available for all swine diseases, and vaccines must be given long before pigs are exposed to work. Do not change rations quickly; sudden ration changes can cause edema disease, which can kill pigs. Vaccinations are recommended for these important diseases because they may kill the pig or make it unfit for exhibition. About 2 weeks after the second erysipelas/APP combination bacterin is administered, the pigs develop an immunity that should make these diseases less severe if they occur. Recognize risks on the farm Even if you use the best management techniques to minimize the exposure of your show pig to disease, you must understand that the pig’s dam, or the sow, can pass disease-causing bacteria and viruses to each pig in the litter. Carelessly using an approved or unapproved product on your show hog may disqualify you from exhibition!
