Composição química e degradabilidade ruminal de silagens da cana-de-açúcar tratada com aditivos químicos e bacteriano

Abstract: ResumoObjetivou-se avaliar o efeito da inclusão de aditivos químicos e bacterianos na ensilagem de canade-açúcar sobre a composição, pH, fracionamento e cinética de degradação in situ dos componentes nutritivos. Utilizaram-se cinco bovinos ½ Simental + ½ Zebu providos de cânula ruminal, alocados em delineamento inteiramente casualizado e alimentados com dietas contendo 76% de volumoso (% MS). Foram avaliadas cinco silagens: controle -cana-de-açúcar sem aditivo; uréia -cana-de-açúcar acrescida de 1,0% de uréia … Show more

“…Besides presenting the smallest b fraction, the cane silage with 40% maniçoba showed higher Kd values, which explains, in part, the greater degradation under this treatment. Fortaleza et al (2012) studied the in situ degradability of sugar cane silage treated with chemical additives and bacteria and found approximate DM degradation rates of 0.018, 0.030, 0.050, and 0.026% h -1 for silage with added urea inoculant, sodium hydroxide, and calcium hydroxide, respectively. Table 4.…”

“…The daily cutting of sugar cane for use as fresh forage, however, demands a large amount of manpower. As a result, producers have opted for sugar cane silage as an alternative (Fortaleza et al, 2012). Besides improving the efficiency of harvesting, sugar cane silage ensures forage availability during periods of food scarcity.…”
