“…These results are in line with those obtained by Salem et al (2013), who reported that fibrolytic enzymes can increase total SCFA concentrations. Similar notable increases were found in the same parameters by Selçuk et al (2016), thus providing more evidence for positive correlations between in vitro OMD, the amount of gas released and ME during fermentation. However, López et al (2013) and Beauchemin et al (2003) reported that suitable fibrolytic enzymes can improve fermentation efficiency, thus increasing metabolized energy, particularly when the substrate is made of fibre-rich material and is limited in nutrient energy.…”

The supplementation of ruminant diets with exogenous cellulolytic enzymes can improve their digestibility and feeding value. The objective of this study was to determine the effect of supplementing roughage (rice straw) and concentrate with inoculants containing four fungal strains (Pleurotus ostreatus, Phanerochaete chrysosporium, Trichoderma reesei and Trichoderma viride) and four bacterial strains (Paenibacillus polymyxa, Bacillus megaterium, Bacillus circulans and Bacillus subtilis), given separately or as a mixture, as a source of exogenous cellulolytic enzymes, on basic rumen parameters in vitro, including digestibility and methane production. A batch culture trial was used to select the best supplements, and a long-term rumen simulation technique (RUSITEC) was used to evaluate the effects of P. chrysosporium, B. subtilis, and a 1 : 1 mixture of these two on dietary component digestibility and fermentation parameters. In the batch culture evaluation, there were significant increases in the organic matter (OM) digestibility, the total gas production expressed as ml/g of dry matter, the OM, the neutral detergent fibre (NDF) and the acid detergent fibre (ADF) of the supplemented rations, as compared to the control, excluding the rations supplemented with T. viride and B. circulans. In the RUSITEC, the ration supplemented with mixed inoculants showed significantly higher digestibility of crude protein, ether extract, NDF and ADF than did the ration supplemented with the P. chrysosporium and B. subtilis inoculants. It can be concluded that the simultaneous use of fungal and bacterial exogenous cellulases on rice straw roughage improves its digestibility, without negative effects on other rumen parameters.

“…The average ADL was in the range of 41 g/kg to 51 g/kg. Although this figure is lower than the 43 to 69.7 g/ kg reported by Rahman et al (2010), the present results confirm the high lignocellulosic content of rice straw as reported by other studies (Hadizadeh et al, 2015;Selcuk et al, 2016;Sheikh et al, 2017;Van Soest, 2006). The fact that Angola rice straw had the least cellulose content implies that it is the better digestible straw.…”

“…Previous studies in other countries have indicated that rice straw contains about 900.0-954.9 g/ kg dry matter, 50-120 g/kg lignin, 30-59.6 g/kg crude protein, 298-370 g/kg crude fibre, 1.4-10 g/ kg crude fat, 0.2-1.6 g/kg phosphorus, 1.4-5.5 g/kg calcium, 44% total digestible nutrients, 7.95 MJ/kg of digestible energy, 80-158 g/kg silica and high oxalates conferring poor digestibility (Singh et al, 1995;Van Soest, 2006;Hadizadeh et al, 2015;Ansah et al 2017) and in some cases toxicity (Bakshi & Wadhwa, 2017;.Drake et al, 2002). Notwithstanding its role as a livestock feed resource in many developing countries, rice straw is rich in polysaccharides on one side, and a high level of lignin conferring it poor nutritive value due to poor digestibility and palatability on the other side (Malik et al, 2015;Selcuk et al, 2016).…”

This study determined and compared the proximate and chemical composition of Angola, IRGA 418 and SUPA rice straw varieties harvested and baled in 2016 and 2017. In both 2016 and 2017, SUPA straw had the highest dry matter (DM) content (960.7 ± 0.50 g/kg and 939.4 ± 0.10 g/kg), neutral detergent fibre (NDF) (575.2 ± 9.90 g/kg and 594.7 ± 9.00 g/kg), acid detergent fibre (ADF) levels (374.7 ± 6.30 g/kg and 379.9 ± 9.90 g/kg) and cellulose (CL) content. Angola straw had the highest crude protein (CP) content (39.1 ± 2.00 g/kg, p < 0.05; 60.7 ± 2.70 g/ kg) and acid detergent lignin (ADL) concentration (p < 0.05) in both years. Organic matter (OM), hemicellulose (HC), ash, fat and mineral content varied with year in all rice straw varieties. Angola straw had the lowest metabolisable energy (ME) of the three straw varieties. All straw varieties were deficient in at least one or more essential nutrient components. Nutritional and chemical composition varied with

“…Semakin tinggi nilai ADF, maka kualitas daya cerna hijauan makanan ternak semakin rendah (Crampton and Haris, 1969 Yanuarianto et al (2015) di Mataram menunjukkan kandungan ADF jerami padi sebesar 52,01%, sedangkan asal Jawa Tengah menunjukkan nilai sebesar 60,57% (Anam et al, 2012). Penelitian kandungan ADF jerami padi asal Thailand oleh Wanapat et al (2013) menunjukkan nilai sebesar 63,7% dan asal Turki sebesar 41,15% (Selçuk et al, 2016). Kandungan ADF yang cukup rendah yaitu 40,95% ditunjukkan oleh hasil penelitian jerami padi di Cina (Yuan et al, 2016).…”

: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.
