In order to lower the cost of pig farming, farmers can integrate chicken raising into their operations. By collecting and properly processing chicken manure—such as drying it or sterilizing it—it can be used as a feed supplement for pigs. This method maintains the nutritional value while reducing feed expenses, making it an efficient and economical feeding strategy.
Another effective approach is using tofu residue and whey from soy milk as pig feed. These by-products are rich in crude protein and help pigs gain weight quickly, allowing them to reach market weight faster and be slaughtered earlier, improving overall productivity.
For full-featured feed preparation, farmers can utilize soybean meal, which is typically expensive. However, after oil extraction, the remaining cake can still be used effectively. Other alternatives like flaxseed, sunflower, peanut, and rapeseed cakes also provide similar nutritional benefits. Using these by-products in feed formulation significantly reduces feeding costs without compromising pig health or growth.
Planting grass for pig feed is another smart strategy. High-yield, nutrient-dense grass varieties such as Bermuda grass or clover can be grown and used as green feed. Mixing different types of grass ensures a balanced diet and makes silage easier to produce. If enough green feed is available throughout the year, it can replace up to 50–60% of concentrated feed, further cutting down on feed costs.
Lastly, distiller’s grains and vinegar residue from brewing processes can be turned into complete mixed feeds for pigs. These materials are not only palatable but also promote rapid growth, making them valuable resources for farmers looking to optimize their feeding strategies.
