Abstract

The present study was aimed to illuminate the nutritional value of the micro-storage mushroom bran, and further to explore a new way for improving its utilization. Silage additives were added to ferment mushroom bran for different days (45 and 60 days), and then the ether extract, crude protein, crude fiber and organic matter contents in the original and micro-storage mushroom bran were detected. Three buffalo with permanent rumen fistulas were used to detect the effective degradation rate of various nutrients in the rumen at different time. The results showed as follows: 1) the contents of crude protein, ether extract, crude fiber and organic matter in micro-storage mushroom bran for 45 and 60 days were 10.47% and 11.04%, 3.10% and 3.24%, 26.99% and 27.49%, 90.21% and 89.53%, respectively. The crude protein content in micro-storage mushroom bran was significantly lower than that in the original mushroom bran (P<0.05), and the contents of ether extract, crude fiber and organic matter were significantly greater compared with the original mushroom bran (P<0.05). 2)The effective degradation rate of dry matter, crude protein and ether extract in micro-storage mushroom bran for 45 days was significantly higher than that in the original mushroom bran (P<0.05), and the effective degradation rate of crude protein in micro-storage mushroom bran for 60 days was significantly higher than that in the original mushroom bran (P<0.05). The micro-storage treatment of mushroom bran can increase the nutrient contents. Micro-storage mushroom bran for 45 days can improve the effective degradation rate of nutrients, and comprehensively use various indicators, micro-storage can be used as a new method for preservation and utilization of mushroom bran. It provides a theoretical basis for the conversion of idle mushroom bran to ruminant feed.
