“…The protein content of CRM used in the present study is higher than the 2.8% (Buitrago & Luckett 1999) and 3.6% (Chauynarong et al 2009;Uchegbu et al 2011) reported. Factors such as cultivar, conditions of the soil and stage of maturity, which have all been reported to affect the composition of cassava products (Ravindran & Ravindran 1988;Agwunobi & Okeke 2000) may be reasons for the higher protein content observed in the present study compared to values in literature. The protein, fat and fibre contents of the experimental copra meal are comparable to the values reported for solvent extracted copra meal (Thorne et al 1989;NRC 1994).…”

A three-week experiment was conducted to investigate the utilisation of a diet based on cassava root meal and copra meal by finishing broiler chickens. A total of ninety-six 21-day-old Cobb broilers were used for the experiment. The birds were weighed and allotted to six pens containing 16 birds each. A finisher diet based on cassava and copra meal and a commercial broiler finisher diet were fed each to three randomly selected pens for a period of 21 days. Results showed poorer (P < 0.05) final body weight, daily feed intake, daily gain and feed: gain ratio of birds fed the test feed compared to those fed the control commercial feed, but feed cost of meat production (WST$/kg live weight) was reduced (P < 0.05) on the test feed. Birds on the commercial feed had higher (P < 0.05) carcass and breast meat yields, while the yields of thighs and drumsticks were not affected (P > 0.05) by the diet. There were no treatment effects (P > 0.05) on the weights of the liver, heart and caeca, but birds on the test feed recorded higher (P < 0.05) weights of the pancreas, gizzard and small intestine. Birds fed the control commercial feed deposited more (P < 0.05) fat than those fed the test feed. It was concluded that cassava copra meal-based finisher diets could be used to reduce cost of meat production and abdominal fat content and thus meat quality of broiler chickens. Further research into appropriate combinations of these ingredients for optimum growth and feed utilisation by broilers is recommended.

“… Agwunobi and Okeke (2000) found in broiler chickens there was no significant difference in apparent metabolisable energy (AME) between 19 different cultivars of cassava. In poultry, the ME content of cassava root meal ranges from approximately 2.87 to 4.27 kcal ME/g DM ( Khajarern and Khajarern, 2007 ).…”

Cassava: Nutrient composition and nutritive value in poultry diets

Insufficient supply, high prices and competition with the human food and biofuel industries means there is a continuous demand for alternative energy sources for poultry. As a result, cassava is becoming an increasingly important ingredient in poultry diets, largely due to its high availability. Efficient use of cassava products has been shown to reduce feed costs of poultry production. The utilisation of cassava is, however, limited by a number of factors, including its high fibre and low energy content and the presence of anti-nutritional factors, primarily hydrocyanic acid (HCN). With correct processing the inclusion level of cassava in poultry diets could be increased. Extensive research has been conducted on cassava products for poultry, but there is still a lack of consistency amongst the measured nutritive values for cassava and its products, hence variation exists in results from poultry studies. This paper reviews the nutrient composition of cassava products and its value as an alternative energy source in poultry diets.

“…The metabolisable energy value of cassava root meals for poultry varies from 12.0 to 14.6 MJ ME/kg of dry matter (Olson et al, 1969, Maust et al, 1972Hutagalung et al, 1974;Fetuga and Oluyemi, 1976;Khajarern et al, 1982). However, Agwunobi and Okeke (2000) studied the AME and chemical composition of 19 cultivars of cassava and observed no significant differences between the cultivars. Silva et al (2000) obtained values of AME and AMEn of 7.10 and 7.08 MJ/kg DM for cassava leaf meal, respectively.…”

Inadequate supply, exorbitant prices and diversion towards using cereal grains for biofuel production, particularly maize, has led to a constant search for alternative energy sources for poultry and other non-ruminant species. The abundant availability of cassava in certain regions makes it a good alternative to maize and other cereal grains. Cassava root meal is rich in carbohydrate but low in protein and all other nutrients, whereas, cassava leaf meal is a moderate source of protein. Results of studies to evaluate the replacement of cereals with cassava products in poultry feed show wide variability due to differences in origin, variety, plant maturity at harvest, ecological conditions of plant growth and processing methods. Cassava products contain a wide range of cyanogenetic glycosides, particularly linamarin and lotaustralin. The level of hydrocyanic acid released from the cyanogenetic glycosides limits the utilization of cassava, but with proper processing, the dietary inclusion level of cassava meal can be increased for economic poultry production. This paper reviews the nutrient composition of cassava and its uses as a substitute for more conventional ingredients in poultry diets.
