“…It is noteworthy, moreover, that the treatment of sugarcane with lime did not cause changes in the palatability or acceptability of the forage, fact supported by the feed intake, result contrary to that obtained by MISSIO et al (2013). However, these results confirm those presented in the literature (CARVALHO et al, 2010;MISSIO et al, 2012) which, in most cases, there was no changes in feed intake by the addition of lime to sugarcane. Nevertheless, MISSIO et al (2013) argue that when the treatment of sugarcane with lime increase the fiber digestibility it is expected higher feed intake in diets with hydrolyzed sugarcane in relation to those with fresh sugarcane.…”

“…Alkaline chemicals are added to roughages to hydrolyse the fibre, partially solubilizing hemicellulose and increasing the digestibility of the material (Carvalho et al, 2010). Rotz (1995) emphasized that the incorporation of non-protein nitrogen into forage subjected to ammoniation leads to an increase in the digestibility and intake of DM.…”

The objective of this study was to determine the effect of diets containing pearl millet silage ammoniated with urea on the intake, digestibility, production performance, and nitrogen metabolism of lambs. Thirty‐two uncastrated mixed‐breed lambs at 4 to 5 months of age, with an average initial body weight of 17.39 ± 2.16 kg, were distributed into four treatments in a randomized block experimental design with eight replicates. Experimental diets consisted of pearl millet silage ammoniated with urea during ensiling at the levels of 0, 20, 40, and 60 g/kg dry matter (DM). Increasing urea levels in the pearl millet silage led to a linear decrease (p < .05) in the intakes of DM, organic matter, and total digestible nutrients by the lambs. Total and average daily weight gains decreased linearly (p < .05) with the addition of urea to the silage. Intake and digestibility of crude protein, nitrogen intake, urine urea nitrogen, plasma urea nitrogen, microbial synthesis, and microbial efficiency had a quadratic response (p < .05) to the urea levels in the silage. Pearl millet silage ammoniated with urea reduces dry‐matter intake and daily weight gain in lambs. Urea is not recommended for use in the ensiling of pearl millet.

Chemical composition and in vitro digestibility of fresh sugarcane hydrolysed with calcium oxide (CaO)

et al. 2015

The objective was to evaluate the chemical composition and in vitro digestibility of sugarcane hydrolysed with increasing doses of calcium oxide and varying air exposure times. A completely randomised, split plot design was used; the doses were allocated to the plots, and the air exposure times were allocated to the subplots, with four repetitions. The data underwent analysis of variance and were laid out according to the effect of the treatment on the components of polynomial regressions, and evaluated at the 5% probability. The increase in the dosage negatively affected the quantities of neutral-detergent fibre (NDF), acid-detergent fibre (ADF), lignin (LIG), total carbohydrates (TC), cellulose (CEL), crude protein (CP), and ether extract (EE); and positively affected the quantities of non-fibrous carbohydrates (NFC) and mineral matter (MM). The addition of calcium oxide improved the in vitro digestible dry matter (IVDMD) coefficients and was able to keep up to 72 hours. The in vitro digestibility of the neutral-detergent fibre (IVDNDF) and of the acid-detergent fibre (IVDADF) coefficients decreased when calcium oxide was added. Calcium oxide has the ability to hydrolyse the fibrous fraction and conserve chopped sugarcane. Doses of 0.5 and 1.0% lime exhibited similar results to those achieved at higher doses; therefore, higher doses are not required in the hydrolyses of sugarcane. Over time, the sugarcane deteriorates, but this deterioration is reduced by the addition of calcium oxide.

Utilizouse o delineamento inteiramente casualizado, em esquema de parcelas subdivididas, sendo as doses alocadas nas parcelas e os tempos de exposição ao ar nas subparcelas, com quatro repetições. Os dados foram submetidos à análise de variância e desdobrados quanto ao efeito de tratamento nos componentes de regressões polinomiais, e avaliados a 5% de probabilidade. A elevação das doses influenciou negativamente os teores de FDN, FDA, LIG, CT, CEL, PB e EE, e positivamente nos teores de CNF e
