Fermenting cow dung for pig feed has been found to be a viable and sustainable practice. Dry cow dung contains approximately 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free extract, and 15%-30% crude fiber, making it a valuable feed resource when properly processed. This is largely due to the fact that cattle are ruminants. Their digestive system, particularly the rumen, hosts a complex microbial community that breaks down fibrous materials and extracts nutrients. Some of these nutrients are absorbed by the cow, while others are excreted in the form of feces, which still contain usable components for other animals. Pigs, being monogastric animals, cannot directly digest raw cow dung. However, with proper fermentation, cow dung can become a nutritious supplement in pig diets. The fermentation process involves mixing the dung with rice bran, wheat bran, or other feed ingredients, and adding a small amount of a microbial starter (about 1 liter per ton of dung). The mixture is then placed in a sealed container such as a silo, plastic bag, or pit and allowed to ferment under anaerobic conditions. This not only improves the palatability of the dung but also enhances its nutritional value. Fermented cow dung can replace part of the regular feed, helping pigs gain weight more efficiently. However, it's important to note that young pigs and piglets should not be fed large amounts of fermented cow dung, as their digestive systems are still developing. For finishing pigs, the recommended inclusion rate is typically between 10%-15%. Since cow dung is high in fiber, it should be introduced gradually into the diet to avoid digestive issues. This method not only reduces waste but also offers an economical and eco-friendly way to improve feed efficiency on farms.
