FERMENTAÇÃO E COMPOSIÇÃO BROMATOLÓGICA DA SILAGEM DE CANA-DE-AÇÚCAR INOCULADA COM LACTOBACILLUS BUCHNERI, ASSOCIADA OU NÃO À ADIÇÃO DE FONTES DE CARBOIDRATOS

It was evaluated the fermentative and bromatological aspects of sugarcane silage with addition of Lactobacillus buchneri inoculant with or without the addition of wheat bran (20%), soybean hull (20%) or the mixture of wheat bran (10%) + soybean hull (20%), using a completely randomized design with four replicates. No significant effects of the treatments on the pH of the silage were observed, however, a higher temperature was observed in the treatment containing 10% of wheat bran + 10% of soybean meal in relation to the control treatment. The addition of carbohydrate sources provided an average increase of 145,86 kg of MV/m³ in the specific mass values and, together with the addition of biological inoculant, dry matter recovery averaged 20,5% higher than the control silage, in addition to increasing the dry matter contents in an average of 2,63% and crude protein in 1,92%. It is concluded that, in isolation, the addition of the biological inoculant was only able to reduce losses of the fermentative process in relation to the control silage and that the addition of carbohydrate sources, both soybean peel and wheat bran, improve the nutritive value of the cane silage.Keywords: silage, inoculation, fermentation characteristics, nutritional value
