[Objectives] This study was conducted to further improve the utilization value of local chestnut leaves, improve the palatability of chestnut leaves and reduce tannin content in chestnut leaves. [Methods] Chestnut leaves and bran were evenly mixed according to different mass ratios, and the mixtures were sprayed and inoculated with a certain amount of prepared EM microbial liquid, and then compressed into 70 cm×40 cm×30 cm blocks by a fully automatic yellow-storage block compression and packaging machine. The obtained blocks were packaged and sealed with plastic film, and placed in a freely ventilated place for more than 15 d of anaerobic fermentation, so as to obtain compressed fermented chestnut leaf block feed. [Results] Through the detection and analysis of nutritional components in the compressed fermented chestnut leaf block feed in the laboratory, the protein content was equal to or greater than 10.2%, which was 44.68% higher than that of unfermented chestnut leaf feed; the tannin content was equal to or greater than 638 mg/kg, which was 18.41% lower than that of the original feed; and the crude fiber content was equal to or greater than 19.5%, which was 14.09% lower than that of the original feed. [Conclusions] This study improves the palatability of chestnut leaf feed, increases the use efficiency of feed and reduces feeding cost. It is worth popularizing. |
