“…Previous research has also identified variations in the nutritional value of rice straw due to the rice crop development cycle (Santos, 2010) and grain production (Shahjahan et al, 1993;Vadiveloo, 2003). In this study, fractions related to secondary cell wall and lignification (acid detergent fiber, neutral detergent fiber, acid detergent insoluble nitrogen, and C nitrogen fraction) were higher in rice straw from cultivars with medium development cycle.…”

“…According to Juliano (1985), for cultivars with medium and long development cycle, photosynthesis extends for a longer period, and consequently, the levels of the fractions linked to the cell wall are higher at the expense of starch and soluble sugars in the vegetative components. Santos et al (2010) also observed that the rice straw from a late development cycle cultivar (M401) showed higher concentrations of acid detergent fiber, lignin, total silica, and neutral detergent silica compared with straw from an early development cycle cultivar (M202), and attributed this difference to greater height of the late development cycle cultivar with longer stem and leaf sheath in relation to the early development cycle cultivar.…”

“…According to Wang et al (2006) and Santos et al (2010), the morphological location of silica in the plant causes differences in the in vitro gas production of rice straw. Another possibility may be related to the low palatability of the food for the animal, due to the presence of highly silicified cells projected on the leaf edge, making the material rough to the touch (Jones and Handreck, 1967), although the participation of leaves is low in the total constitution of the bale.…”

-The objectives of this study were to evaluate the effects of cultivation and hay making factors on chemical composition, protein fractionation, and digestibility in rice straw, as well as to identify the chemical fractions that contribute to the variation in its nutritional value for ruminants. Statistical procedures were performed in a model that included rice crop cycle, sowing season, baling season, soil classification, fertilizer application, and productivity (kg/ha) as fixed effects and the hay bale as random effect. Chemical composition, protein fractionation, and digestibility data were subjected to multivariate analyses including factor, cluster, and discriminant. Considering the cultivation and haymaking factors, development cycle, baling season, and grain production explained the most variation in the rice straw nutritional value. Straws derived from early maturing cultivars showed the lowest levels of neutral detergent fiber, acid detergent fiber, acid detergent insoluble nitrogen, and C nitrogen fraction in comparison with straw originating from mid cycle cultivars. Rice straw from more productive cultivars had lower levels of lignin and C fraction as well as higher levels of crude protein and B3 fraction compared with straws from less productive cultivars. However, the main variation in the nutritional value between the samples of rice straw was related to the baling season. The bailing seasons were grouped in two clusters. Straws with better nutritional value were those with lower levels of cell wall fractions, from more productive crops, with early development cycle and baled until March. Rice crop cycle, baling season, and grain production effects explain the variation in the nutritional value of rice straws. Straws with better nutritional value have lower levels of fractions related to secondary cell wall and lignification.

:The basic reason for poor performance of livestock in developing countries includes Indonesia, is qualitative fluctuations in the feed. Therefore knowledge in utilizing agroindustry byproduct as feedstuff to meet the nutrient requirement of animals is important. Rice straw is a crop residue of rice production and can be used as a feed for ruminants because it is easily and cheaply available in many Asian countries. Rice straws have low nutritive value and it is generally limited by several factors such as the low nutritional quality due to high fiber content and lignification process. In Indonesia, rice straw has been widely utilized in livestock feeding systems, thus the need to improve them is imperative as they are an abundant crop residue. Much more attention has been paid to improving its feeding value in order to increase livestock productivity. Many processing methods to improve the nutritive value of rice straw have been investigated. These methods can be classified as physical, chemical or biological. Usually, processing methods improve the nutritive value of straw by increasing its digestible energy content, by increasing feed intake, or by a combination of the two. This paper aims to examine the potential of rice straw as basal feed livestock as well as efforts to improve their nutritional value.

“…The content of silica in the rice straw is larger than other plants. Organic components in rice straw is cellulose (32-47%), hemicellulose (19-27 %), lignin (5-24 %), and ash (13-20 %) (Santos et al, 2010). Ash constituents depend on the type of rice, climatic, and geographical conditions where rice is grown (Zaky et al, 2008).…”

Silica is the most abundant components in the earth's crust and is made by way of synthesis for use in the application of technology. Silica are generally found commercially as alkoxysilane compounds (i.e such as tetraethylorthosilicate (TEOS), sodium silicate, and tetramethylorthosilicat). However, these compounds can have a negative impact on health. Thus, further approaches to find the source of silica that is safer, cheaper, and more environmentally friendly is inevitable. However, not all summary journals are thoroughly discussed the silica sources. Further, method of isolation and application of the silica from agricultural waste is limited. This paper reported studied several sources of silica derived from agricultural waste, such as rice husk, rice straw, corn cobs, and bagasse. In addition, this paper discussed also about the method of isolation of silica from agricultural waste, and its application as a catalyst.
