AI Technical Summary
Fresh brewer's grains have a high water content and are rich in nutrients, making them susceptible to microbial contamination and spoilage. Furthermore, their complex coarse fiber structure affects digestion and absorption, resulting in low utilization rates when fed directly.
Fresh brewer's grains were anaerobicly fermented using a compound strain of Lactobacillus plantarum, Lactobacillus bryonicus, and Saccharomyces cerevisiae. The mixture was then combined with cornmeal, wheat bran, whole cottonseed, beet granules, and grass meal. Moisture content was controlled, and the mixture was sealed for anaerobic fermentation. With precise moisture control and cellar management, fresh brewer's grains fermented feed was prepared.
It improves the digestibility and shelf life of fresh brewer's grains, reduces the risk of spoilage, increases milk production in dairy cows and fattening efficiency in beef cattle, conforms to the green circular agriculture policy, and has high promotion value.
