Abstract
This study was undertaken to characterize feed value and silage quality according to storage period and film layers for whole-crop barley silage. The crude protein (CP) content increased in all silage during the storage periods compared to those before silage, this content slightly increased over the prolonged storage period but it was not significant (p>0.05). Depending on the film layers of silage, 6 layers were higher than 4 layers. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents also increased in all silage during storage periods compared to those before silage (P<0.05), but they were maintained at similar levels during the storage period. Depending on the film layers of silage, 6 layers were higher than 4 layers. The total digestible nutrients (TDN) content decreased in all silage during the storage periods. However, it was maintained at a similar level for the duration of each storage period. Depending on the film layers of silage, 6 layers were lower than 4 layers. The pH value was decreased during the prolonged storage period and depending on the film layers, 6 layers were lower than 4 layers. In the organic acid contents during the prolonged storage period, lactic acid increased, acetic acid was lower, and butyric acid was significantly higher (p<0.05). Depending on the film layers, 6 layers showed higher levels of lactic acid and lower levels of butyric acid (p<0.05). Therefore, these results showed that 6 layer wrapping was advantageous for long term storage of whole crop barley silage, while also indicating that it is desirable to use 4 layer wrapping within a six month period.
