不同粗饲料在水牛瘤胃中的降解特性研究
The Degradation Characteristics of Different Roughage in the Rumen of Water Buffalo
摘要
Abstract
This study aimed to compare the nutritional value of three roughage types-sweet potato vine,corn stalk silage,and peanut vine-and their degradation characteristics in the buffalo rumen,and to provide a reference for their utilization in the buffalo farming industry.Three healthy crossbred buffaloes with sim-ilar body weights(680.0±25.2 kg),fitted with permanent ruminal fistulas,were selected.The nylon bag technique was used to determine the ruminal degradation rates of dry matter(DM),crude protein(CP),neutral detergent fiber(NDF),and acid detergent fiber(ADF)of the three feed ingredients.The results showed that:(1)The CP and Ash contents of sweet potato vine were higher than those of the other two roughages(P<0.05),while its DM,NDF,and ADF contents were the lowest.(2)The ruminal DM deg-radation rate of corn stalk silage was significantly lower than that of sweet potato vine and peanut vine at all time points(P<0.05).(3)The CP degradation rate of sweet potato vine was significantly higher than that of corn stalk silage and peanut vine from 48 to 72 hours(P<0.05).(4)Except for at 12 hours,where no significant difference was observed between sweet potato vine and peanut vine(P>0.05),the NDF and ADF degradation rates of sweet potato vine were significantly higher than those of corn stalk silage and peanut vine at all other time points(P<0.05).The experiment indicates that sweet potato vine has high CP content and high ruminal degradation rates of DM,NDF,and ADF in buffalo,demonstrating its po-tential as a high-quality unconventional roughage for dairy buffaloes.关键词
