发酵剂对紫苏秸秆发酵饲料品质及营养成分的影响
Effect of different treatments on the quality and nutrition of fermented Perilla frutescens straw
摘要
Abstract
As the first batch of medicine,food,and traditional multi-purpose economic plants promulgated by the ministry of health,Perilla frutescens has high nutritional value.The aim of this study was to determine the effects of different treatments on fermentation of P.frutescens straw.The experiments were divided into 5 groups including thecontrol group,group Ⅰ(with 20% corn flour 20 g+1 g·kg—1Qiangwei 99 starter cul-tures+0.1 g·kg—1crude fiber degradation agent+50 mL·kg—1Trichoderma fermentation solution added), group Ⅱ(with 20% corn flour+1 g·kg—1Qiangwei 99 starter culture added),group Ⅲ(with 20% corn flour+1 g·kg—1crude fiber degradation agent added),group Ⅳ(with 20% corn flour+50 mL·kg—1Tri-choderma fermentation solution added).All groups had 3 replicates.The results showed that the sensory score, pH,and contents of organic acids(acetic acid,propionic acid,and butyric)and ammoniac nitrogen in groupsⅠ and Ⅱ were significantly lower than that of the control group and the other groups(P<0.05).Compared with the control group,the contents of crude fiber(CF)and acid detergent lignin(ADL)decreased significant-ly and the opposite occurred for crude protein(CP)and crude fat(EE)in the four different treatment groups. Neutral detergent fiber and acid detergent fiber decreased significantly in group Ⅰ and Ⅲ(P<0.05).Howev-er,the content of ash between the control group and different treatment groups was not significantly different. The above results showed that adding 20% corn flour 20 g+1 g·kg—1Qiangwei 99 starter cultures+1 g·g—1 crude fiber degradation agent+50 mL·kg—1Trichoderma fermentation solution was the best treatment for fer-mentation of P.frutescens straw.关键词
