Resumo: | This study aimed to evaluate the effects of increasing the neutral detergent fibers (NDF) concentration of sugarcane-based diets on the growth and development of Holstein heifers. Twenty-seven Holstein heifers with a mean body weight of 265.5 ± 36.4 kg were housed in a sand bedded tie stall and fed individually. The experimental diet consisted of fresh sugarcane and concentrate. Three concentrations of sugarcane NDF were compared: 33% (SC33), 38% (SC38), and 42% (SC42). Crude protein content of experimental diets was 16%. The following parameters were evaluated: dry matter intake, weight gain and morphometric measures, digestibility, feeding behavior, and ruminal pH. The experimental design was a randomized block and all analyses were performed using the MIXED procedure in SAS. Intake of DM decreased as NDF concentration increased (p=0.07), but weight gain and growth were not significantly affected (p=0.74). As dietary NDF increased, chewing activity per unit DM intake increased (p=0.001), but rumen pH was not significantly affected (p=0.91). Diets formulated with 330?420 g of sugarcane NDF/kg of dry matter were sufficient to support the growth of Holstein heifers. |

Os animais experimentais foram vinte e sete novilhas da raça Holandesa pesando em média 265,5 ± 36,4 kg, alojadas em um Tie Stall com camas de areia e alimentadas individualmente. A ração experimental total era composta por cana-de-açúcar e concentrado. Testou três concentrações dietéticas de FDN oriundo da cana-de-açúcar: 33% de FDN (SC33); 38% FDN (SC38) e 42% FDN (SC42). O teor de proteína bruta da ração foi de 16%. Foram avaliados consumo de matéria seca, ganho de peso e parâmetros corporais, digestibilidade, comportamento alimentar e pH ruminal. O delineamento foi em blocos casualizados, e a analise estatísticas pelo proc MIXED do programa SAS. O consumo de matéria seca foi menor com o aumento de FDN da dieta (P=0,07), mas isso não interferiu no ganho de peso e crescimento dos animais (P=0,74). A maior inclusão de FDN na ração resultou em aumento na atividade mastigatória por unidade de matéria seca ingerida (P=0,001) e não interferiu no pH (P=0,91). Pode-se concluir que rações formuladas com até 420 gramas de FDN oriundo de cana-deaçúcar por kg de matéria seca dietética foram adequadas à fase de crescimento de novilhas Holandesas.Universidade Estadual de Londrina2020-05-22T14:00:50Z2020-05-22T14:00:50Z2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfGALLO, P.
