This study investigated the metabolizable energy (ME) intake, net energy of production (NEp), heat production (HP), efficiencies of ME use for energy, lipid and protein retention as well as the performance of broiler chickens fed diets based on cassava chips or pellets with or without supplementation with an enzyme product containing xylanase, amylase, protease and phytase. The two products, ca...

Cassava mosaic disease (CMD) is the most widespread and economically important disease of cassava (Manihot esculenta Crantz) in tropical Africa. A disease of cassava was first described in East Africa in the nineteenth century (Warburg, 1894) and cassava mosaic, as it came to be called, was subsequently reported as spreading throughout the cassava-growing areas of Central and West Africa (Calve...

Cassava starch is a main renewable bio-resource with low price and mass production in Guangxi, China. It was used as carbon source in growing Xanthomonas campestris pv. campestris 8004 (Xcc 8004) for xanthan gum production in this study. The xanthan gum yield of gelatinized cassava starch was higher than that of raw cassava starch; the maximal reducing sugar and amylase activity reached 14.30 g...

Cassava (Manihot esculenta Crantz) is a food plant introduced in Africa from America by the Portuguese in 1558. The objective of this study is to establish cassava origins, production, and utilization in Burkina Faso. The investigation was carried out in the regions of Center West, Cascades, Boucle du Mouhoun, Hauts Bassins, South West, and Center East of Burkina Faso. Eighteen cassava processi...

Cassava (Manihot esculenta Crantz) is currently the most important upland crop of Cambodia, but information on yield variations and causal factors which is important for efficiently targeting efforts to increase production is still lacking. The objectives of this study were to determine the yield variations and causal factors for cassava production in Kampong Cham province in Cambodia. Fort...

The addition of 0; 5; 10 and 15% cassava bagasse, based on the dry matter of the total diet of crossbred Holstein v. Zebu cows, was evaluated on milk production and composition and on the impacts of diet costs. The animals, weighing an average of 478.5 kg, were in the middle third lactation period. Diet with 15% cassava bagasse provided a 13.2% increase in production when compared to control. F...

Since 1990 we have undertaken a large number of experiments and conducted research on the development and use of cassava roots and leaves as animal feed resources, in order to explore the possibility of substituting cassava-based feeds for those of grain, thus saving grain for human consumption that was previously used for feeding animals. We have conducted chemical analyses to determine the nu...

The purpose of this study was to evaluate the prospective production of ethanol from cassava in Indonesia. The study was conducted in two parameters, engineering perspectives and economic evaluation that involves several economic parameters (e.g. gross profit margin, internal rate return, payback period, cumulative net present value, breakeven point, and profitability index on sales to investme...

Production of αamylase under solid state fermentation by Streptomyces erumpens MTCC 7317 was investigated using cassava fibrous residue, one of the major solid waste released during extraction of starch from cassava (Manihot esculenta Crantz). Response surface methodology (RSM) was used to evaluate the effect of the main variables, i.e., incubation period (60 h), moisture holding capacity (60%)...

UNLABELLED Cassava mosaic begomoviruses (CMBs) cause cassava mosaic disease (CMD) across Africa and the Indian subcontinent. Like all members of the geminivirus family, CMBs have small, circular single-stranded DNA genomes. We report here the discovery of two novel DNA sequences, designated SEGS-1 and SEGS-2 (forsequencesenhancinggeminivirussymptoms), that enhance symptoms and break resistance ...
