The effect of urea addition on giant reed ensilage and sequential anaerobic digestion (AD) of the ensiled giant reed was evaluated. The dry matter loss during ensilage (up to 90 days) with or without urea addition was about 1%. Addition of 2% urea enhanced production of lactic acid by about 4 times, and reduced production of propionic acid by 2-8 times. Besides, urea addition reduced degradation of cellulose and hemicellulose, and increased degradation of lignin in giant reed during ensilage. Ensilage with or without urea addition had no significant effects on the enzymatic digestibility of giant reed, but ensilage with urea addition achieved a cumulative methane yield of 173 L/kg VS, which was 18% higher than that of fresh giant reed. The improved methane yield of giant reed could be attributed to the production of organic acids and ethanol during ensilage.

“…The nutritional value of rice straw can be upgraded by different methods. Physical, chemical (Sarwar et al, 2004a;2004b) and biological treatments have been used to weaken and break down ligno-cellulose bonds in crop residues, thereby increasing their feeding value for ruminants. In India, burning of straw is the major method for disposal that causes atmospheric pollution and nutrient loss.…”

Rice straw, a by-product of the rice production is mainly used as a source of feed for ruminant livestock is the major forage in rice-producing areas in India. The disposal of the rice straw is a serious problem in areas where it is the major agricultural product. It is rich in polysaccharides and has a high lignin and silica content, limiting voluntary intake and reducing degradability by rumen microbes. By rice straw treatment, its quality and digestibility can be improved and enhanced the protein content. Several methods have been used to improve the utilization of rice straw by ruminants or supplemented by other ingredients to increase digestibility and nutrient value before it can be considered a suitable animal feed. In recent years, biological treatments have been investigated for improvement in nutritional value of rice straw. The use of ligninolytic fungi and their extracellular ligninolytic enzymes for treatment of rice straw results in degrading cellulose and hemicelluloses contents which improve its nutritional value. The use of fungi and enzyme treatments is expected to be a practical, cost-effective and environmental-friendly approach for enhancing the nutritive value and digestibility of rice straw. Therefore, the treated rice straw has a good potential as feed for ruminants.

“…Banyak penelitian telah dilakukan selama beberapa dekade yang bertujuan untuk meningkatkan nilai gizi dari jerami padi, dengan tingkat keberhasilan yang beragam (Selim et al, 2004;Sarnklong et al, 2010). Usaha peningkatan kualitas jerami padi tersebut dilakukan dengan cara meningkatkan nilai cernanya melalui pemecahan ikatan kompleks lignoselulosa baik secara mekanik/ fisik (Sarwar et al, 2004), kimia dan biologis maupun kombinasinya (Doyle et al, 1996). Metode metode tersebut diatas secara umum digunakan untuk melemahkan dan memecah ikatan ligno-selulosa pada jerami, sehingga nilai nutrisi akan meningkat (Malik et al, 2015).…”

: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.
