Effects of molasses and Lactobacillus plantarum on silage quality,microbial quantity and rumen degradation rate of hop branches and leaves
摘要
Abstract
[Objective]Effects of molasses and Lactobacillus plantarum on silage quality,microbial quan-tity and rumen degradation rate of hop branches and leaves.[Methods]In this experiment,hop branches and leaves were used as raw materials to study the effects of adding molasses and Lactobacillus plantarum on fer-mentation characteristics of hop branches and leaves silage and rumen degradation rate of sheep.The treatments were no additive treatment(CK treatment),5%molasses(Molasses,M0 treatment),5%molasses +105 CFU/g FM Lactobacillus plantarum combination(Molasses and Lactobacillus plantarum,M1 treatment).After 90 days of storage at room temperature(19-23℃),the sensory quality was evaluated,the silage quality and microbial quantity were analyzed,and after that,the rumen degradation rate was determined.[Results](1)The sensory quality evaluation of M0 and M1 treatments was better than that of the control treatment.The DM of M1 treat-ment was significantly higher than that of CK and M0 treatments(P<0.05).The CP of M1 treatment was sig-nificantly higher than that of CK treatment(P<0.05).The NDF of M1 treatment was significantly lower than that of CK and M0 treatments(P<0.05).The ADF of M0 and M1 treatments was significantly lower than that of CK treatment(P<0.05).The LA of M1 treatment was significantly higher than that of CK and M0 treatments(P<0.05).The AA of M1 treatment was significantly higher than that of CK treatment(P<0.05).The pH and NH3-N/TN of M0 and M1 treatments were significantly lower than those of CK treatment(P<0.05).(2)The lactic acid bacteria of M1 treatment was significantly higher than that of CK and M0 treatment(P<0.05),and the yeast of M0 and M1 treatment was significantly lower than that of CK treatment(P<0.05).(3)At 12 h of rumen degradation,there was no significant difference in DMD among the treatments.The OMD,AD-FD and NDFD of M0 and M1 treatments were significantly higher than those of CK treatment(P<0.05).At 24 h of rumen degradation,DMD of M1 treatment was significantly higher than that of CK treatment,OMD,ADFD and NDFD of M0 and M1 treatments were significantly higher than those of CK treatment(P<0.05).At 48 h of rumen degradation,DMD and ADFD of M1 treatment were significantly higher than those of CK and M0 treat-ments(P<0.05),OMD and DNFD of M0 and M1 treatments were significantly higher than those of CK treat-ment(P<0.05).[Conclusion]Molasses and Lactobacillus plantarum plays a good synergistic effect in the fermentation of hop branches and leaves silage,can effectively improve the quality of silage,inhibit the growth of harmful microorganisms during hop branches and leaves silage,and promote the activity of rumen microor-ganisms.关键词
