Fermenting cow dung for pig feed has been found to be a valuable 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 rich source of nutrients. When properly processed, it can be transformed from waste into a useful resource. This is largely due to the fact that cattle are ruminants. Their digestive system, particularly the rumen, hosts a complex community of microbes that break down plant material and release nutrients. Some of these nutrients are absorbed by the cow, while others are excreted in the form of microbial protein and rumen fluid. These components can then be utilized by monogastric animals like pigs.
However, raw cow dung is not suitable for direct feeding to pigs. It’s best to ferment it first, turning it into silage. The process involves mixing the cow dung with rice bran, wheat bran, or other feed materials. An appropriate amount of a microbial starter, such as "gold bait feed starter," is added—about 1 liter per ton of mixture. The mixture is then packed tightly into a cellar, silo, or plastic bag and left to ferment under anaerobic conditions. After fermentation, the cow dung becomes more palatable and can replace part of the regular feed, helping pigs gain weight more efficiently.
It's important to note that young pigs and piglets should not be fed large amounts of fermented cow dung. For finishing pigs, the inclusion rate should generally not exceed 10%-15%. Since cow dung is high in fiber, it should be introduced gradually into the diet to avoid digestive issues. Always monitor the pigs' health and adjust the feeding plan accordingly.
