摘 要:【目的】感官评价不同比例籽用西葫芦皮瓤与玉米秸秆混贮效果,测定pH值、挥发性脂肪酸(VFA)和营养成分含量变化研究适宜添加比例。【方法】籽用西葫芦皮瓤与玉米秸秆为0∶1时作为对照组(DM 51.32),两者混合比例为1∶1、1∶2和2∶1分别作为A组(DM 40.32)、B组(DM37.56)和C组(DM 47.70)。两者按比例混合均匀后装入800 mL太空杯中,压实后密封确保无空气流通,室温避光保存。每组均设置6个处理组,60 d时取样评价青贮饲料的感官指标,测定青贮饲料pH、VFA和营养成分的变化。【结果】对照组和B组混贮尚好,A组合C组感官评价优。混贮饲料中pH值对照组极显著高于A、B和C组(P<0.01);B组极显著高于A组和C组(P<0.01)。乙酸含量对照组与B组和C组差异显著(P<0.05);A组与B组、C组差异显著(P<0.05);其他各组间差异不显著(P>0.05)。各组中均未测出丁酸含量,异丁酸含量对照组与A组和C组差异显著(P<0.05),与B组差异极显著(P<0.01)。总挥发性脂肪酸(TVFA)对照组极显著高于A组、B组和C组(P<0.01);C组显著高于A组合B组(P<0.05);其他各组间差异不显著(P>0.05)。随着籽用西葫芦皮瓤比例的增加混贮中干物质(DM)含量、酸性洗涤纤维含量(ADF)和中性洗涤纤维(NDF)含量降低,但粗蛋白(CP)含量升高。【结论】籽用西葫芦皮瓤与玉米秸秆1∶1混合混贮最优。【Objective】In this experiment,different proportions of Seed Pumpkin waste and corn straw were mixed for storage.Through sensory evaluation of mixed storage,the changes of pH value,VFA and nutrient content were determined to explore the appropriate proportion.【Methods】The control group(DM 51.32)was treated with 0∶1 of Seed Pumpkin waste and corn straw,and the mixture ratio of 1∶1,1∶2 and 2∶1 was used as group A(DM 40.32),group B(DM 37.56)and group C(DM 47.70),respectively.After the two were mixed in proportion,they were put into an 800 mL space cup,sealed after compaction to ensure no air circulation,and kept away from light at room temperature.Six treatment groups were set up in each group.The sensory indexes of silage were evaluated at 60 d,and the changes of pH,VFA and nutritional components of silage were determined.【Results】The control group and group B had good micro storage,while group A and group C had excellent sensory evaluation.The pH value of control group was significantly higher than those of A,B and C groups(P<0.01);Group B was significantly higher than those of group A and group C(P<0.01).The content of acetic in control group was significantly different from those in group B and group C(P<0.05);There was significant difference among group A,group B and group C(P<0.05);There was no significant difference among other groups(P>0.05).The content of isobutyric in control group was significantly different from that those in group A and group C(P<0.05),and significantly different from that in group B(P<0.01).The TVFA in control group were significantly higher than those in group A,B and C(P<0.01);Group C was significantly higher than that of group B(P<0.05);There was no significant difference among other groups(P>0.05).The contents of DM,ADF and NDF decreased,but the content of CP increased.【Conclusion】It is recommended that the seed be mixed with 1∶1 corn straw.
