Effect Of Different Silage Additives On Eight Forage Species Silage

Take the Medicago sativa,Hordeum brevisubulatum,Lespedeza hedysaroides, Ceratoid -es arborescens, Astraglus adsurgens, Medicago ruthenica, Elymus dahuricus and corn stalk as silage raw materials,By studying different additives on quality of forage silage,and find suitable additive of silage. The results showed that:1. Additives played an important role to improved the sensory silage,decreased pH value, increased lactic acid content,improved the crude protein content and decreased all kinds fiber content, However,The role of various additives is not consistent because the different raw materials silage.The additive (Caihe) significantly increased the CP (crude Protein)content (19.90%)and decreased pH value of silage (4.18).Additives(Caihe) effectively inhibited the activities of the harmful bacteria and promoted the activities of the lactic acid bacteria. Caihe to significantly increased lactic acid content(77.31%)of Medicago sativa silage, Effect of three additives could be arranged as follows, Caihe>Yishengkang> Qingbao.2. Medicago sativa and grasses and shrubs mixed in storage, the effect of separate silage was better than Medicago sativa and other forage mixed silage,the weight rate of Medicago sativa and grasses and shrubs mixed in storage processing without any additives, Taking LA content as the major index to evaluate the quality of silage, and combined with other indicators could be drawn from the overall result of the treatment to silage quality were Medicago sativa and Lespedeza hedysaroides(2:1)>Medicago sativa and Lespedeza hedysaroides and Ceratoides arborescens(1:1:1)>Medicago sativa and Hordeum brevisubulatum(1:1)>Medicago sativa and Lespedeza hedysaroides and Ceratoides arborescens (3:2:1)> Medicago sativa and Hordeum brevisubulatum (2:1)> Medicago sativa and Ceratoides arborescens(2:1)>Medicago sativa and Lespedeza hedysaroides (1:1)> Medicago sativa and Ceratoides arborescens (1:1) .3. Sugar beet pulp and corn stalk,Elymus dahuricus mixed silage received very good results, lactic acid content was more than 80% and no butyric acid in all of threatment. Additive(Cai he) significantly decreased fiber content (P<0.05),and crude protein content of two mixed silage were higher than control.4. Effect of additives on dynamic changes of the quality fermentation of Astraglus adsurgens, pH value and lactic acid content significantly changed in 3 days to 15 days, and ease changed from 15 days to 60 days;acetic acid content significantly decreased in the whole process(P<0.05). propionate acid content change from few to many to few in the whole ensilage process, propionate acid content meet minimum at 45 days in all various stages.5. The fermention quality of Medicago ruthenicus silage could not be enhanced by Silage Guart with high density, lactic acid content and crude protein content of Medicago ruthenicus could not be increased .However, the effect was more evident along with the Lalsil Fresh density. quality fermentation of Medicago ruthenicus has significantly improved,of which 3% LF has significantly increased crude protein content and content of lactic acid was (9.24%)higher than control(P<0.05). It is concluded that the forage silages treated with additives can be to stored longer so that forage silage can be supplied steadily for animal husbandry.
