Studies On Mixed Silage Of Dolichos Lablab With Different Gramineae

Lab\ab[Lablab purpureus(Linn.)Sweet] native to Australia, in our country, it is a new legume forage in recent years. Lablab resistant to stress, with late-maturing characteristics, content high crude protein, good palatability, but with more legumes high buffering capacity and low soluble carbohydrate content, typically single reservoir silage quality is not good. Gramineae typically have a high content of soluble protein and lower in carbohydrates, sugar is fermented silage substrate, and therefore easily silage grasses success. Lablab and Gramineae mixed silage can make up for lack of another, improve silage silage quality. In this paper, Lablab as silage material, and Lablab single reservoir as the control, with three kinds of Gramineae in different proportions (3:7,5:5,7:3,0:10) mixed silage, and in 30 days 60 days and 90 days after the determination of its fermentation quality and nutrition screening mixing ratio adaptation, and compare the impact of time on the silage mixed storage materials:(1) Lablab and Zea diploperennis mixed silage:each scale mixed storage material pH value, AN/TN were significantly lower than in Lablab single reservoir (P<0.05), sensory Grading and nutrients were significantly Lablab higher than single reservoir (P<0.05), after 90 days of silage fermentation system remains stable. Silage at 30 days 5:5 with the highest quality mix hoppers.(2) Lablab and Pennisetum mixed silage:the proportion of mixed hoppers each sensory and fermentation quality were significantly higher than single Lablab reservoir (P<0.05), lower than nutrients Lablab single reservoir.30 days to 60 days silage mixed storage material quality significantly decreased (P<0.05),60 days after the mixed storage material without significant change. Silage at 30 days 3:7 mixed storage material processing under the highest quality.(3) Lablab and Sorghum mixed silage:the proportion of mixed hoppers each sensory and fermentation quality were significantly higher than Lablab reservoir (P<0.05). Since sweet sorghum silage dry matter content and Lablab close, and the highest relative content of soluble sugar compound, mixed storage material differences between silage quality and Lablab single reservoir unlikely. Time on silage crude protein content on a significant other ingredients in the silage after 60 days no obvious rule. Silage at 30 days 3:7 mixed storage material processing under the highest quality.
