“…Regarding the use of sugarcane, results were consistent with those obtained by Pinto et al (2010), who did not find changes in weight or carcass composition by replacing sorghum silage with sugarcane. Likewise, Rotta et al (2014) did not find changes in carcass weight, degree of fatness, yield, or cooling loss testing different sugarcane ratios in feedlot cattle diets, which can be attributed to similar slaughter weights.…”

“…However, when the BMB inclusion levels reduced animal performance, which occurred for higher levels of BMB inclusion in this study, feed conversion increased (Miotto et al, 2013;Alencar et al, 2015). For the use of sugarcane, on the other hand, the obtained results were similar to those reported by Pinto et al (2010), who evaluated different proportions of sugarcane replacing sorghum silage and found no changes in feed conversion of confined cattle, despite the lower weight gain in diets with sugarcane.…”

The objective of this study was to evaluate the production performance of feedlot cattle fed diets containing chopped sugarcane ratios (580 or 380 g/kg of diet dry matter) as roughage and levels of inclusion of babassu mesocarp bran (BMB; 420 to 620 g/kg of concentrate dry matter). Twenty-four young Nellore bulls with 321±23 kg initial body weight, at 22 months of age, were used in a completely randomized experimental design with treatments in a 2 × 2 factorial arrangement and six replicates. Dry matter intake (21.71 g/kg of body weight), average daily gain (1.46 kg/day), and cold carcass weight (232.59 kg) were not changed by proportion of sugarcane or BMB level. The proportions of sugarcane and BMB levels did not change the apparent digestibility of the diets, except the digestibility of neutral detergent fiber, which was lower in the diet associating the lowest levels of sugarcane and BMB. Increasing proportions of sugarcane reduced subcutaneous fat thickness from 2.89 to 1.91 mm. Carcass commercial primal cuts were not affected by variation factors. Inclusion of babassu mesocarp bran enables the use of larger proportions of sugarcane as a result of the increased digestibility of the fiber fraction of feedlot cattle diets without changing the performance and main carcass traits of these animals.

“…As both burning and CaO application accounted for reductions in the DMI of steers for reasons discussed earlier, steers fed burned silage diets containing CaO had BW loss during the adaptation period, as expected. Under some conditions and depending on the diet formulation, more traditional forage sources (e.g., fresh sugarcane and corn and sorghum silages) provide higher growth performance of beef cattle compared with feeding systems based on sugarcane silage because of reduced DMI (Menezes et al, 2011;Moraes, Val-adares Filho, Moraes, & Pina, 2015;Pinto et al, 2010 Daniel et al, 2016;Rabelo et al, 2016) and (c) formation of undesirable end products during fermentation other than ethanol and acetic acid, as neither affects the growth performance of beef cattle and dairy cows (Daniel, Amaral, Goulart, et al, 2013;Daniel, Amaral, Sá Neto, et al, 2013 intakes are expected to be lower because the burned silage diets contained lower OM and aNDF concentrations than the in natura silage diet. In the same way, steers fed CaO-treated silage diets had lowered aNDF intake because these diets contained lower aNDF concentration.…”

In this study, the effects of days postburning and calcium oxide (CaO) on the fermentation, aerobic stability and nutritional characteristics of sugarcane silages for finishing Nellore steers were investigated. Silages were prepared in minisilos from in natura and burned sugarcane that remained in the field 1 and 10 days postburning (1‐day burned and 10‐day burned, respectively). Next, forages were left untreated or treated with CaO (10 g/kg fresh forage). Compared to that in untreated silages, CaO application increased the dry‐matter (DM) recovery of in natura, 1‐day and 10‐day burned silages (p < 0.001) by 67, 179 and 209 g/kg DM respectively. The CaO treatment increased (p < 0.001) the aerobic stability of the in natura and 10‐day burned silages by 62.7 and 24.7 hr respectively. In a feedlot experiment, feeding 1‐day burned silage reduced DM intake of steers throughout the feedlot period (0–93 days; p < 0.05) compared with that of steers fed in natura silage diet, but the average daily gain (ADG) was lower (p = 0.006) only during the adaptation period (−0.16 kg/day; 0–28 days). The CaO application decreased DM intake (p = 0.007; −1.17 kg/day) and ADG (p < 0.001; −0.13 kg/day) of steers only during the adaptation period likely owing to low silage palatability caused by increased Ca and butyric acid concentrations (≥11.6 g/kg DM). We recommend feeding beef cattle with CaO‐treated burned sugarcane silages in low‐dietary concentration because of its high butyric acid concentration.

“…Dessa forma, busca-se o conhecimento do valor nutritivo dos alimentos, que pode ser obtido através da composição química, de digestibilidade e pelo próprio desempenho animal, e a partir daí a formulação de dietas balanceadas que possibilite uma melhor eficiência alimentar. Nesse contexto, estudos comprovam que a cana-de-açúcar apresenta resultados promissores com base em índices produtivos e econômicos (Queiroz et al, 2008;Pinto et al, 2010;Romam et al, 2011), todavia pode tornar-se uma realidade alimentar para caprinos leiteiros. Ainda são incipientes os trabalhos encontrados na literatura utilizando-se a cana-de-açúcar como volumoso para esses animais.…”
