“…The lower results of fraction C, for the silage that was stored with CaO levels, was agreement with Roth et al (2016). These authors also observed a decrease in the proportion of fraction C at different levels of ammonization in Brachiaria hay.…”

“…Carvalho et al (2013) reported that addition of CaO resulted in a lower NDF content in the silage after 180 days of fermentation compared with that observed following the other treatments. The effectiveness of an alkaline treatment was described in other roughage feedstuffs by Khorvash et al (2010) and Roth et al (2016), who studied the effects of CaO and calcium hydroxide (Ca(OH) 2 ) on the quality of soybean straw and observed a reduction in NDF content. Roth et al (2016) indicate that the levels of lime (15 and 20 g kg À1 ) reduced the fiber fraction and enhanced aerobic stability for both fresh and burned silages.…”

“…To this end, the best results have been obtained from the use of alkaline additives, such as sodium hydroxide (BoladoRodr ıguez et al 2016;Janke et al 2016), calcium hydroxide (Oliveira et al 2008;Pina et al 2009) and calcium oxide (CaO) (Padua et al 2014;Roth et al 2016).…”

The objective of this study was to evaluate, based on chemical composition and in vitro dry matter (DM) digestibility, silages of different sugarcane genotypes after exposure to different doses of calcium oxide (CaO) and to identify that most appropriate dose for use in ruminant feed. The experiment was conducted using a completely randomized 3 9 4 factorial arrangement with three sugarcane genotypes ('IAC-862480', 'SP-791011' and 'CTC-3') and four levels of the additive CaO (0, 15, 30 and 45 g kg À1 ). A quadratic effect was observed (P < 0.05) for DM content in the silages of genotypes 'SP-791011' and 'CTC-3'. The organic matter content of genotypes 'SP-791011' and 'CTC-3' showed a negative linear effect that was associated with the addition of CaO, which promoted an increase in the mineral matter (MM) content in the silages. There was no effect (P > 0.05) of genotype or an interaction effect between genotype and CaO level on crude protein content in the silages. There was an interaction effect (P < 0.05) between genotype and CaO level on the level of neutral detergent fiber in the studied silages and the development of this interaction revealed a linear decrease in neutral detergent fiber in genotype IAC-86280 and a quadratic effect (P < 0.05) for genotypes 'SP-791011' and 'CTC-3'. Potentially degradable DM (pdDM) values showed a positive quadratic function with maxima at 34.8 g kg À1 CaO. The results obtained for potentially degradable neutral detergent fiber (pdNDF) showed that there was a negative linear effect for genotype 'SP-791011' and a quadratic effect with the maximum critical point for genotypes 'IAC-862480' and 'CTC-3'. Total DM losses decreased with levels of CaO. All genotypes evaluated showed potential for silage production. The addition of CaO in the ensiling of sugarcane at up to 45 g kg À1 reduces gas and effluent losses and increases the DM recovery of the silages.

“…Sugarcane is a tropical grass often harvested during the dry season and used as feed for livestock. During the dry season, the risk of accidental burning over the sugarcane field is high; this could burn the leaves and straw of the forage, preventing its use in a direct cut system (Roth et al., ). Hence, ensiling of burned sugarcane has been proposed to save forage and to avoid higher losses of quality and dry matter (DM) in this situation (Roth et al., , ).…”

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.
