基于隶属函数法分析不同类型添加剂对饲草谷子青贮品质的影响OA

This study aimed to investigate the effects of different types of additives on the silage quality of forage foxtail millet.Three varieties of forage foxtail millet,namely Cao 6,Cao 28,and Zhangqinggu 5,were used as experimental materials.Each variety was divided into five treatment groups,the control group(group CK)without any additives,and the additive treatment groups were added 0.1%EM complex microbial inoculant(group EM),0.1%cellulase(group C),0.5%urea(group U),and 0.1%cellulase+0.5%urea(group CU),respectively.Each group was replicated three repetitions.After 60 days of fermentation,the nutritional quality of forage in each group was measured.The results showed that the sensory scores of each group of silage were all good.Compared with group CK,the pH value of group EM decreased across all varieties,while the pH value of group U increased.Group CU exhibited the highest crude protein(CP)content and the lowest acid detergent fiber(ADF)and neutral detergent fiber(NDF)levels among all varieties.The water-soluble carbohydrate(WSC)content of group U for Cao 6 and group EM for Cao 28 was significantly lower than those of their respective group CK(P<0.05).Based on the comprehensive evaluation using the membership function method,group CU achieved the highest scores for both Cao 6 and Cao 28,with scores of 3.967 and 5.355,ranking first and third overall,respectively.In contrast,group CK of Zhangqinggu 5 had the highest score(3.281),ranking fifth overall.The study shows that Cao 6 and Cao 28 are suitable for silage treatment with a composite additive of cellulase and urea,while Zhangqinggu 5 can be ensiled directly or with the addition of the EM complex microbial inoculant.
