| This study aimed to evaluate the productive performance of dairy cows fed with sugarcane treated with 5g kg-1 of calcium oxide (CaO) or hydroxide [Ca(OH)2]. Eight Holstein cows with 638.01±12.52kg of body weight and milk yield of 20.32±1.5kg d-1 were randomly assigned into two 4x4 Latin squares, fed with the following diets composed of corn silage (CS), fresh sugarcane (FS), sugarcane treated with calcium oxide (STCO) or calcium hydroxide (STCH) as only forage. Data collection lasted five days, after 15 days of adaptation to diets and facilities. The dry matter intake (% of body weight) was higher in diets with CS (3.08) compared to those with FS (2.67), STCO (2.73) or STCH (2.73), which did not differ. Diets with CS determined milk production adjusted for... |

| Objetivou-se avaliar o consumo de nutrientes e o desempenho de novilhas Nelore alimentadas com dietas contendo cana-de-açúcar in natura (CN) ou hidrolisada (CH) com 0,5% de Ca(OH)2 armazenada por 24, 48 e 72 horas. Foram utilizadas 24 novilhas com nove meses de idade e 119,6±8,1kg de peso corporal inicial. O delineamento experimental utilizado foi o inteiramente casualisado com quatro tratamentos e seis repetições. O consumo de matéria seca foi reduzido em 29% pela adição de Ca(OH)2, não sendo alterado pelo período de armazenamento da CH. O consumo de cálcio foi incrementado (P<0,05) pela utilização de CH nas dietas, mantendo níveis de ingestão aceitáveis. Novilhas alimentadas com CH armazenada por 24, 48 e 72 horas apresentaram, respectivamente, ganhos... |

| The objective of this study was to evaluate, in Nellore heifers, intake and digestibility of hydrolyzed sugarcane stored for different periods. The experimental design used was a 4 × 4 Latin square, four diets, four Nellore heifers with ruminal cannulas (initial body weight 285.4±23.08 kg and average initial age 14 months) and four periods of 21 days. The diets were composed by fresh sugarcane (time zero) or hydrolyzed sugarcane with addition of 0.5% of hydrated lime, stored for 24, 48 or 72 hours, as the unique forage. Intake and digestibility of feed fractions, nitrogen balance, microbial synthesis efficiency, total number of ruminal protozoans and ammoniacal nitrogen did not significantly change by storing sugarcane with addition of 0.5% of hydrated... |

| The objective of this study was to evaluate the chemical characteristics of the forage and ingestive behavior of Nellore heifers fed hydrolyzed sugarcane in different periods of storage. Twenty-four heifers with initial body weight of 119.6±8.1 kg were utilized. The experimental design was completely randomized, in which the treatments were diets with fresh sugarcane and hydrolyzed sugarcane (5 g of lime kg-1 of chopped sugarcane) stored for 24, 48 or 72 hours as the only roughage. The addition of lime to sugarcane associated with its storage up to 72 hours provided an increase of 20% of the potentially degradable cell wall of carbohydrates, from 382.4 to 458.8 g kg-1 of total carbohydrates. The in vitro digestibility of dry matter was altered by the... |
