The popularization of "microbial fermented feed" reduces pig farming costs by 30% and is more environmentally friendly.

Feed costs account for 70% of the total cost in the pig farming industry, and a 'feed revolution' is quietly taking place. The 'microbial fermentation feed technology' developed by Shandong Biotechnology Company converts kitchen waste, straw, and other waste into high-protein feed through black water fly breeding and compound microbial fermentation. Specifically, black water fly larvae can efficiently decompose organic waste, with a protein content of 42% in the insect body. After replacing part of the soybean meal, the feed cost is reduced by 30%. At the same time, the fermentation microbial agent can improve the digestion and absorption rate of feed, reducing nitrogen and phosphorus emissions from pig manure by 25%. In a cooperative pig farm in Guangxi, the fattening pig slaughter cycle was shortened by 10 days using this technology, and the comprehensive profit per pig increased by 150 yuan. The more profound impact is that this model has established a closed-loop industrial chain of 'waste resource utilization - feed production - breeding emission reduction', reducing land occupation and carbon emissions. Currently, over 100 feed enterprises across the country have deployed this technology, and the Ministry of Agriculture and Rural Affairs has listed it as a key promotion project to help the pig farming industry break through the bottleneck of feed costs and achieve a win-win situation of economic and ecological benefits.
