“…Azevedo et al (2003), when working with three varieties of sugar cane, one in its early stages (SP 80-1842) and two at intermediate cycles of maturity (RB 84-5257 and SP 79-1011), highlighted the low contribution of sugar cane CP in feed formulation based on this forage. The results of this study agree with those obtained by Ribeiro et al (2009b) who found no effect of CaO and sodium hydroxide on the crude protein content of sugar cane.…”

The aim of this study was to identify the most adequate level of calcium oxide (CaO) in the treatment of sugar cane by evaluating the chemical composition and in vitro digestibility of dry matter. The sugar cane was homogenized with CaO levels 0, 0.75, 1.5, 2.25, 3.0, 3.75 and 4.5%, in natura matter, for 24 hours. The dry matter and mineral matter increased, while the organic matter of the sugar cane decreased (P <0.05) linearly as a result of the CaO levels. The CaO had no effect on the levels of crude protein and ether extract. The phosphorus concentration remained unchanged, but there was a significant increase (P<0.05) in the calcium content. The contents of neutral detergent fiber, acid detergent fiber and cellulose decreased linearly with the levels of CaO. The average levels of indigestible dry matter and indigestible neutral detergent fiber significantly decreased with increasing levels of CaO. The results showed that the in vitro dry matter digestibility (IVDMD) was different between fresh sugar cane and sugar cane with added levels of CaO from 1.5%. The IVDMD and nutritional value of the sugar cane was improved by adding 1.5% CaO based on fresh content.Keywords: additive, forage, hydrolysis, Saccharum, alkaline treatment CaO 0; 0,75; 1,5; 2,25; 3,0; 3,75 RESUMO O objetivo foi identificar o nível mais adequado de óxido de cálcio (CaO) no tratamento da cana-deaçúcar por meio da avaliação da composição química e a digestibilidade in vitro da matéria seca.

“…According to Wilkinson and Gonzalez (1978) and Klopfenstein (1977), the ADF and LIG contents are usually unaffected by alkali treatment. However, at greater calcium oxide doses, these compounds may be affected by the alkali as observed in the present study; this finding corroborates the study by Ribeiro et al (2009), who observed that a high dose (2.25%) of calcium oxide was also capable of reducing the ADF and LIG contents.…”

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.

“…Con el fin de mejorar la digestibilidad de la fracción fibrosa y conservar el material picado, la caña de azúcar se ha tratado con productos químicos alcalinizantes como el hidróxido de sodio (NaOH), hidróxido de potasio (KOH), hidróxido de calcio (Ca (OH) 2 ), amoniaco anhídrido (NH 3 ) y óxido de calcio, estos agentes actúan parcialmente solubilizando la hemicelulosa e incrementando su digestión por los microorganismos, expanden las moléculas de celulosa, rompen los puentes de hidrógeno y aumentan la tasa de pasaje en el rumen. A la caña tratada con este tipo de sustancias se le conoce como caña hidrolizada (Kling et al, 2008;Pina et al, 2009;Ribeiro et al, 2009;Galindo y Rubio, 2011). Pese a que los resultados son positivos con NaOH, este se ha evitado debido a la contaminación ambiental, exceso de sodio en la dieta, heces y orina de los animales, y especialmente por el daño potencial a la salud humana; por otro lado, el NH 3 tiene desventajas, asociadas a su alto costo y baja potencia hidrolítica (Nussio et al, 2003).…”

Introducción. La caña de azúcar tiende a incrementar sus demandas de producción, considerando las perspectivas macroeconómicas a nivel mundial, debido a que el mercado tiene altos requerimientos de azúcar y melaza para la producción agroindustrial. Objetivo. El objetivo de esta revisión fue determinar el estado del arte en que se encuentra el uso del cultivo de caña de azúcar (Saccharum spp.) y los subproductos derivados de su proceso agroindustrial en la alimentación de rumiantes. Desarrollo. La industria de la caña de azúcar, como una especie proveedora de diferentes materias primas y subproductos resultantes de la transformación a panela o azúcar, presenta en la mayoría de los países dedicados al cultivo, ciertos problemas tecnológicos relacionados principalmente con el desperdicio y desaprovechamiento del bagazo, la cachaza y la cachaza deshidratada. Sin embargo, existen diversos estudios tendientes a demostrar la utilización de los subproductos en la alimentación animal, especialmente de rumiantes, mediante diversas tecnologías, que permiten mejorar la calidad y disponibilidad de los nutrientes en los mismos, para ser aprovechados por el animal. Conclusiones. Los subproductos de la caña de azúcar han sido utilizados para la elaboración de harinas, bloques y ensilajes, lo cual abre nuevos caminos en pro de un sistema de producción sostenible y amigable con el ambiente. Además, permiten hacer a un lado la concepción que se tenía en Colombia de que los subproductos agroindustriales eran de poco valor y su obtención generaba un impacto ambiental negativo.
