Fermentation feed can significantly improve feed utilization, especially as agricultural practices evolve. With the adjustment of planting structures, large-scale livestock farming has become a dominant model. Traditional feeding methods have shifted from roughage to more concentrated feeds such as corn, barley, sorghum, soybeans, potatoes, wheat bran, and oil cakes. While these feeds are rich in nutrients, they often contain hard-to-digest components like seed coats, husks, and starches. Additionally, certain concentrates may include substances such as tannins, which can hinder nutrient absorption. Other factors, like antitrypsin and prothrombin, also act as inhibitors that reduce the efficiency of digestion.
To overcome these challenges, fermenting concentrated feed before use is an effective solution. This process not only enhances digestibility but also improves nutrient absorption. The following section outlines the method of fermentation modulation.
Fermenting concentrate feed is one of the most widely used techniques for pigs and cattle. It involves using professional feed starters—specialized microbial cultures that break down carbohydrates under optimal temperature, humidity, and oxygen conditions. These microbes produce lactic acid, acetic acid, and ethanol, resulting in a slightly acidic, aromatic fermented feed.
After fermentation, the feed becomes more palatable and easier to digest. It also increases the availability of crude protein and boosts the levels of vitamin B. Moreover, the fermented concentrate supports better appetite, overall health, and reproductive performance in livestock. By improving the quality of feed, fermentation plays a key role in modern animal husbandry, helping farmers achieve better productivity and sustainability.
