| The aim of this experiment was to evaluate, by means of the semi-automated in vitro gas production technique, fermentation kinetics of carbohydrates and degradability of dry matter (DM) and organic matter (OM) of diets containing oldman saltbush hay levels (8.4; 18.8; 31.2 and 48.3%) associated to forage cactus in natura. Pressure readings of the gases were done with a pressure transducer at 2, 4, 6, 8, 10, 12, 17, 20, 24, 28, 34, 48, 72 and 96h post-inoculation. The rumen kinetics was described by the following parameters: maximum potential of gas production, lag time and production rates of gas (k), fibrous carbohydrates (FC) and non-fibrous carbohydrates (NFC). It could be observed that the addition of oldman saltbush hay to the diets promoted a... |

| Avaliaram-se o fracionamento de carboidratos e a degradabilidade in situ da matéria seca (MS) e da fibra em detergente neutro (FDN) da cana-de-açúcar tratada com óxido de cálcio (CaO). Foram testadas as porcentagens de 0; 0,75; 1,5; 2,25; 3,0; 3,75 e 4,5% de CaO, e o material testemunha (cana-de-açúcar in natura) para a avaliação do fracionamento de carboidratos, e as porcentagens de 0; 1,5; 3,0 e 4,5% de CaO para a avaliação da degradabilidade in situ da MS e da FDN. O CaO foi adicionado em pó na cana-de-açúcar, em porcentagem da matéria natural, por 24 horas. A porcentagem de inclusão de CaO na cana-de-açúcar proporcionou valores mais baixos para teores de carboidratos totais (CT) comparados aos valores da cana-de-açúcar in natura. Observou-se... |

| The aim of this study was to identify the most adequate level of calcium oxide (CaO) in the treatment of sugar cane by evaluating the chemical composition and in vitro digestibility of dry matter. The sugar cane was homogenized with CaO levels 0, 0.75, 1.5, 2.25, 3.0, 3.75 and 4.5%, in natura matter, for 24 hours. The dry matter and mineral matter increased, while the organic matter of the sugar cane decreased (P <0.05) linearly as a result of the CaO levels. The CaO had no effect on the levels of crude protein and ether extract. The phosphorus concentration remained unchanged, but there was a significant increase (P<0.05) in the calcium content. The contents of neutral detergent fiber, acid detergent fiber and cellulose decreased linearly with the... |
