Sugarcane with Elephant grass replacing sugarcane with urea in the diet of crossbred dairy cows1

“…The treatment with 50% replacement of sugarcane for elephant grass (50% SC + 50% EG) resulted in higher DMI compared to the other treatments, in line with the findings of Cabral et al (2015), who observed that the addition of sugarcane to goat diets caused a linear decrease in DMC. Low DMI reported in diets with sugarcane as source of roughage has been frequently related to the low digestibility of sugarcane fiber (Cabral et al, 2015;Salomão et al, 2015). In the present study, the digestibility coefficients of NDF (NDFD) between the abovementioned treatments were similar (p > 0.05%; Table 3).…”

“…Sugarcane has a higher iNDF content (Table 1), and its digestible fraction is usually degraded in the rumen more slowly (Pereira et al, 2000). These characteristics cause the food to stay longer in the rumen, leading to ruminal fill and, consequently, to limited DMI (Cabral et al, 2015;Sampaio et al, 2009). This theory corroborates with the research conducted by Magalhães et al (2004) with dairy cows, in which the addition of sugarcane to their diets decreased ruminal passage rates, which directly affected DMI.…”

Use of sugar cane to feed lactating dairy goats

“…For Van Soest (1994), lignin is presented as a limiting factor for fiber degradation, due to the barrier formed making it difficult for microbial adhesion and colonization to break complex bonds. Consequently, the effect of physical replenishment to the rumen environment is highlighted, caused by the indigestible fraction resulting in a reduction in the apparent digestibility of DM, NDF and ADF of the diets with the replacement of sugar cane (Table 3), considering that the lignin-cellulose complex and the crystallinity of this cellulose hinder digestion, characterizing the proportion of indigestible fiber present in the cell wall of sugarcane, which has been evidenced by some authors who have worked with sugarcane in food of ruminants, justifying the low IDM and apparent NDF digestibility coefficient (Cabral et al, 2015, Souza et al, 2017.…”

“…Among Brazilian agricultural crops, sugarcane (Saccharum officinarum) ranks second place in the worldwide production ranking (Figueroa-Rodríguez et al, 2019), given its importance for the generation of sugar and biofuels. However, due to the need to reduce costs in animal feeding and greater economic return to the rearing system, this has been used and shown to be a nutritionally viable food alternative (Oliveira et al, 2019Cabral et al, 2015Worku et al, 2015;Nyakira et al, 2015).…”

Suplementação com melaço de soja na dieta de ovinos: parâmetros sanguíneos, consumo, digestibilidade e comportamento ingestivo

“…Busca-se o conhecimento do valor nutritivo dos alimentos, que pode ser obtido através da composição química, da quantificação do consumo de nutrientes, bem como o seu aproveitamento pelo animal, verificado por meio de provas de digestibilidade, além do comportamento ingestivo (CABRAL et al, 2015). O estudo com comportamento ingestivo compreende uma ferramenta fundamental na avaliação do alimento, pois a partir dele poderão ser realizados ajustes em relação à forma de utilização do alimento observado e o nível de substituição que proporcione o melhor consumo e desempenho.…”
