“…It is the most productive crop in terms of energy yield per unit land area (Ravindran and Blair, 1992). Among the starchy staples, it gives carbohydrate yield of about 40% higher than rice and 25% more than maize, making it the cheapest source of calories in animal diets (Tonukari, 2004). It has energy value of more than 3000 MJ metabolizable energy per kg and contains 2.55% CP, 27.75% CF, 0.12% EE and 1.70% ash on a DM basis (Sriroth et al, 2000).…”

A 42-day study was carried out with ninety 14-day old broiler chickens (Cobb 500) to evaluate the dietary inclusion of cassava flour in full replacement with maize on growth performance, carcass characteristics and haematological parameters. The chickens were randomly allotted to 6 pens involving two dietary treatments of three replicates per each treatment and 15 birds per each replicate in a Complete Randomized Design. Variables measured included feed intake, weight gain, feed conversion efficiency, mortality, feed cost, and haematology. Feed and water were provided ad libitum. Results indicated that the total inclusion of cassava flour in broiler diet reduced (P>0.05) feed intake. Also, there was a depression (P<0.05) in the growth rate and feed efficiency in the broiler chickens fed on the cassava flour based diets during experimental period. Again, replacing maize with the cassava flour in broiler diet reduced (P<0.05) the dressing percentage of carcass. However, haematological parameters were not affected by dietary treatments. Nonetheless, the cost of feed was reduced with the substitution of maize with cassava flour in broiler diet. In conclusion, the total replacement of maize with cassava flour in broiler chickens diets has deleterious effect on growth, but reduced the cost of feeding, thereby resulting in higher net revenue.

The objective of this study was to evaluate the variation in nutrient composition of cassava pulp from four different sources (starch manufacturers) in Thailand. Moisture content varied with drying process, being lowest in the oven-dried product and highest in the sample that was sun-dried. Gross energy content ranged between 16.2 and 16.84 MJ kgG 1 while fat, crude protein starch contents were approximately 0.4-0.9, 2.0-4.0 and 37.0-75.0%, respectively. The sun-dried pulp from Chonburi contained the highest concentration of calcium, sodium, magnesium, iron and manganese. Phosphorus and potassium were 0.32-0.63 and 2.28-8.86 mg kgG 1 , respectively. The amino acid contents in cassava pulp were low, in line with the protein content (1.39-2.45%). Lysine, methionine and isoleucine were 0.82-1.24, 0.06-0.18 and 0.54 -1.40 mg gG 1 , respectively. Most of the Non-Starch Polysaccharides (NSP) were in insoluble forms (approximately 40-90 g kgG 1 ) whereas soluble NSP was between 13.93 and 16.21 g kgG 1 . The main sugars in the insoluble NSP were xylose, galactose and mannose.

“…It is a perennial shrub cultivated in many continents as an important food source, because cassava roots are high in calories and is one of the largest producers of carbohydrates (Adeoti, 2010), it is the fourth most consumed source of carbohydrates in the tropics, and have high starch making it the staple food for over 500 million people (Tonukari, 2004).…”

Sandy soils of 19 arable fields were analyzed for disease suppressiveness against root rot disease of cassava, caused by Fusarium solani CFF109. Analysis of chemical, physical, biochemical, microbial population and activity, and soil characteristics were assessed. Soils with different management histories and covers most commonly found in the region were collected to build a greenhouse experiment, to evaluate the natural suppressiveness of soils against cassava root rot. The severity was submitted with all data across correlation and multivariate analyses to find correlation between disease suppressiveness and abiotic or biotic soils attributes. Differences in disease suppressiveness were found between the treatments for cassava root rot. Significant disease suppression was found in 37% of the soils. The sandy soil covered with consortium of Zea mays + Vigna unguiculata was the most efficient in suppressiveness against disease caused by F. solani. The data indicated significant correlation between soil characteristics and suppressiveness cassava root rot. The soil supressiveness against cassava root rot was favored by increase by total bacteria, fluorescent group bacteria populations and activity of acid and alkaline phosphatase and β-glucosidase.
