Abstract

The aim of this study was to investigate the effects of different cutting heights on yield, nutritional composition, silage fermentation quality and in vitro fermentation of hybrid paper mulberry. In this study, paper mulberry with a growth height of 1.6 m was harvested and three different cutting heights (20, 35 and 50 cm) groups were set, respectively. After harvesting, the paper mulberry nutritional composition and yield were measured. The paper mulberry was ensiled using polyethylene bottle with a density higher than 1 000 kg/m³ and preserved at room temperature for about 45 days. After ensiling, the nutritional composition, fermentation quality and in vitro fermentation tested of paper mulberry silage were conducted. The results showed that with the cutting height increased from 20 to 35 cm, the paper mulberry neutral detergent fiber (NDF), acid detergent fiber (ADF) and total phosphorus contents significantly decreased (P<0.05), crude protein (CP), calcium (Ca) and total tannin contents significantly increased (P<0.05), while the yield, ether extract (EE) and ash contents had no significant difference (P>0.05). Cutting height increased from 35 to 50 cm, paper mulberry yield and NDF content decreased significantly (P<0.05), EE, ash and total tannin contents significantly increased (P<0.05), while the CP, ADF and total phosphorus contents had no significant difference (P>0.05). The dry matter, lignin content and buffer capacity had no significant difference among the three different cutting heights (P>0.05). There were little effects of different cutting height on silage fermentation quality. The pH, ammonia-nitrate (NH₃-N), lactic acid, propionic acid and butyric acid contents had no significant difference among three groups (P>0.05). But acetic acid content of paper mulberry silage with 50 cm cutting height was significantly higher than that in other two groups (P<0.05). Compared with fresh sample, the NDF content of paper mulberry with a cutting height of 50 cm decreased significantly after ensiling (P<0.05). There was no significant difference in in vitro dry matter digestibility (IVDMD), gas production (GP), NH₃-N and microbial crude protein (MCP) contents among different groups (P>0.05). The acetic acid, propionic acid, butyric acid and total volatile fatty acid contents of fermentation fluid in 30 cm cutting height group were higher than those in 50 cm group (P<0.05). Therefore, it is concluded that 35 cm is the best cutting height for paper mulberry harvesting.
