Chemical composition and quality of conservation of corn (Zea mays L.) grain silages with differents levels of soy grains (Glycine max Merril)

Abstract

It was aimed to assess the effects of different percentages of soy bean grain, added to corn grain, on fermentation characteristic and chemical composition of silages. The treatments tested were: corn grain silage with 0, 10, 20, 30 , 40% different levels of soy bean grain. Experimental silos with approximate 12 kg of capacity were used. They were sealed for 12 months and after that they were opened to get samples for chemical analysis. It was used a completely randomized design, with three replicates per treatment. The addition of raw soy bean grain, increased the content of nutrients (Ash, CP and EE) of silages, without interfering the fermentation quality of the silage.
