In order to evaluate the feeding value of sugarcane bagasse as roughage for ruminant, three sugarcane bagasses were comprehensively evaluated from the nutritional composition, total sugar content, gross energy, mycotoxin content and feed relative value (RFV). The results showed as follows: 1) based on dry matter(DM), there was no significant difference in the nutritional component of three sugarcane bagasses (P < 0.05).2)There were significant differences in the mycotoxin contents of aflatoxin(AFB1), vomit toxin(DON) and zearalenone(ZEN) (P < 0.05),but contents of three mycotoxin were within the limited range.3) There was no significant difference in the gross energy, total sugar content and RFV(P < 0.05). The gross energy contents of three sugarcane bagasses were 16.34,16.41 and 16.40MJ/kg, respectively.The total sugar contents of three sugarcane bagasses were 4.33%, 4.46%, and 4.51%, respectively. The RFV of three sugarcane bagasses were 52.89,53.25, and 54.74, respectively. In conclusion, the level of CP, EE, Ca and TP was low in Panxi area, while the contents of CF, NDF, ADF and ADL were high.The contents of AFB1, DON and ZEN were all within the limited range. In general,the feeding value of bagasse in Panxi was low. |
