Fontes de amido e proteína para vacas leiteiras em dietas à base de capim elefante

Abstract: RESUMO: A correta associação de fontes concentradas de energia e/ou proteína ao volumoso da ração de bovinos, poderá maximizar o desempenho dos animais, como efeito da complementariedade das taxas de degradação de nutrientes. Avaliou-se o efeito de diferentes formas de processamento de milho, níveis de inclusão na dieta e fontes de proteína sobre a digestibilidade dos nutrientes na dieta, parâmetros de fermentação ruminal, bem como o desempenho de vacas leiteiras. Foram utilizadas cinco vacas da raça holandesa… Show more

“…For all forages, NDF contents in the fourth cut were above 72%, which can cause low intake. [26] reported that NDF is relevant to the improvement of the forage nutritional value and can be an important parameter to define the forage quality, because the more fibrous pasture occupies more space for longer and limits the intake rate. Similarly, [27] evaluated the Marandu palisadegrass intercropped with corn and obtained 72% NDF.…”

“…These results are assigned to the lowest fiber content in the soybean and cotton meals (Table 1) compared with sunflower and canola. Lima et al (2002) reported that NDF content is important to improve the nutritional value of the forage, being an important parameter to define the forage quality, because the most fibrous food takes up space for longer time and limits the intake rate.…”

“…This greater reduction at a height of 30 cm was expected due to the increased amount of leaves present. The NDF content is inversely proportional to diet energy density, and the NDF values above 60% are negatively correlated with forage intake [18]. The ADF content of the grasses was 35.57%, 34.06%, and 31.60% at heights of 10, 20, and 30 cm, respectively; this showed that even when cultivars were managed at a height of 10 cm, the ADF content was within the appropriate range [19], who reported that forage grasses with an ADF content of approximately 40% or more led to low consumption and lower digestibility.…”
