Chemical composition and dry matter digestibility of sugar cane oxide treated with calcium

Abstract

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.

Nutrient Contents in Sugarcane Biomass in the First Regrowth Cycle

“…Ca contents were similar among the varieties and the plants presented 0.15 dag kg -1 on average ( Figure 6). Romão et al (2014) examined the chemical composition of variety 862480 treated with calcium oxide and found an average of 0.23 dag kg -1 , compared to a biomass concentration of 0.14 dag kg -1 for the control treatment (without CaO), both of which were similar to this study. Calcium is essential in the growth of sugarcane and this is evidenced by the high amounts extracted by the plants.…”

Nutrient content and in vitro degradation study of some unconventional feed resources of Bangladesh

“…(2015) reported 21.39% CP in Hypnea spp, which is higher than our studies. Sugar cane bagasse had higher (75.6%) NDF compared to all other feed ingredients ( Table 1 ), which was higher than that of 58% reported by Romao et al. (2014) .…”

Óxido de CaO e hidróxido de (Ca(OH)2) no tratamento de volumosos

“…Sendo assim, dietas utilizadas para alimentar os animais no período seco que visam além de manter o peso dos animais, melhorar seu desempenho, seja na produção de leite ou de carne, são extremamente importantes para diminuir a sazonalidade da produção. Uma das formas de atingir esse objetivo é com a melhoria da digestibilidade dos volumosos através da adição de aditivos alcalinos, que por meio da hidrólise, beneficiam o valor nutricional desses alimentos (Romão et al, 2014).…”
