Evaluation of mixing silage of Musa paradisiaca stems and leaves and Stylosnthes guianensis
摘要
Abstract
This experiment was excuted to exploit the quality of fermentation of mixed Musa paradisiaca stems and leaves and Stylosnthes guianensis .Four treatment groups were set according to the proportion of S .guianensis ,100% M .paradisiaca stems and leaves,100% S .guianensis ,75% banana stems and leaves with 25% S .guianensis ,50% M .paradisiaca stems and leaves and 50% S .guianensis ,each treatment con-tains 3 replicates.After 5 weeks of fermentation,the sensory evaluation and laboratory test of silage were car-ried out.The results showed,100% M .paradisiaca stems and leaves group got the best quality in sensory evaluation,100% S .guianensis group got 6 in sensory evaluation,the lowest in all groups,mixed silage groups were in the middle of all groups,the quality of mixed silage were evaluated with the growing ratio of ba-nana stems and leaves.The 100% M .paradisiaca stems and leaves group got the lowest pH value,with the rising ratio of S .guianensis ,the value of pH (P ﹤0.01)and the colony count of lactobacillus (P ﹤0.05)were improved.The acetic acid of 100% S .guianensis group was the lowest,no significant differences were ob-served in the lactic acid and butyric acid of all groups(P >0.05),no significant differences in fermentation qual-ity due to the content;75% M .paradisiaca stems and leaves and 25% S .guianensis group improved the con-tent of lactic acid and acetic acid and the colony count of lactobacillus.With the improving ratio of S .guianen-sis ,the content of water and water soluble carbohydrates (WSC)were depressed(P ﹤0.05 ),the content of crude protein and crude fiber were improved significantly(P ﹤0.05).With the sensory evaluation and laboratory tests,mixture of M .paradisiaca stems and leaves and S .guianensis reduced the water content,increased the content of WSC of S .guianensis ,improved the quality of fermentation of mixed silage,and the best quality is 75% M .paradisiaca stems and leaves and 25% S .guianensis .关键词
