Abstract

The aim of this project is identify the height of Guineagrass that provides a better fermentation pattern of fresh mass used to make silage, besides define the combination of additives that improve the aerobic stability. Two experiments will be performed in Ilha Solteira UNESP. In the first experiment will be evaluated six sward heights (50, 70, 90, 110, 130 and 150 cm) and two seasons (Spring/Summer and Autumn/Winter). It will evaluate the chemical, qualitative compositions and fermentation capacity of fresh mass for each treatment. In the second experiment the best height observed at experiment 1 will be assessed. At that time, the grass will be ensiled using or no combined (i) citrus pulp and (ii) homo and (iii) heterofermenters bacteria evaluating the chemical, qualitative composition and aerobic stability silage.
