“…The average determined ME of all meals tested was 3.20 kcal/g; the lower and upper values being 3.06 and 3.39, respectively. These values are similar to the value of 3.44 reported by Olson et al (1969) but lower than the value of 4.31 obtained by Maust et al (1972) and the value of 3.88 reported by Fetuga and Oluyemi (1976). The difference between values may have been due to differences in composition, probably related to the cultivar of cassava used.…”

“…However, the information about some of its nutritive characteristics is very scarce. There are earlier reports about the metabolizable energy (ME) of cassava meals for chicks (Olson et al, 1969;Maust et al, 1972;Fetuga and Oluyemi, 1976), but there is no information published about its net energy (NE). The objective of this study was to determine the ME and NE values of cassava meal for chicks.…”

In a series of experiments with chicks, metabolizable and net energy values of cassava meal were obtained. Metabolizable energy determinations were conducted on samples of five cassava meals, the average being 3.20 kcal/g. Average daily gains and feed to gain ratios were not significantly different (P>.05) between cassava samples and starch. Net energy value of cassava meal was obtained by calculating the energy gain per unit of ingredient intake by the comparative slaughter technique. The average net energy value of cassava meal was 2.28 ± .09 kcal/g. Net energy of cassava meal as a fraction of metabolizable energy was 74.9%.1979 Poultry Science 58:694-698

“…Even though GADELHA et al (1969) obtained feed depression due to high dietary levels of cassava, palatability did not appear to be a contributory factor to the growth rate depression of chicks (ENRIQUEZ and ROSS, 1967), nor could a deficiency of essential fatty acids be implicated. and ENRIQUEZ, 1969), up to 3O0/o or even higher dietary levels of substitution may not depress performance if the metabolizable energy and the crude protein of the diets are balanced (OLSON et al, 1969). The adjustment of protein is made with special regard to methionine.…”

Summary Cassava flour is processed in Nigeria by peeling the tubers, drying them in the sun and then grinding them to a fine powder which is sieved through a fine mesh. This ingredient was tested on chicks (0–9 wk) and growers (10–20 wk) of the White Rock strain. The results indicated that in terms of weight gain, feed intake and mortality, the cassava flour could replace 10 % of the maize in the diet of the chicks but not in the diet of the growers. The cassava reduced the metabolizable energy of the diet and tended to reduce the nitrogen retention of the birds. Zusammenfassung Untersuchungen über den optimalen Maniokgehalt (Manihot esculenta Crantz) im Kückenfutter Maniokmehl wird in Nigeria in folgender Weise gewonnen: Die Knollen werden geschält, dann an der Sonne getrocknet, fein gemahlen und dann durch ein feines Netz gesiebt. Das Mehl wurde an Kücken im Alter von 0–9 Wochen sowie an solchen im Alter von 10–20 Wochen geprüft. Aufgrund der Gewichtszunahme, Futteraufnahme und Mortalität vermag Maniokmehl bei den 0–9 Wochen alten Tieren 10 % des Mais' im Futter zu ersetzen, hingegen ist dies bei den 10–20 Wochen alten Tieren nicht mehr der Fall. Maniok reduzierte die metabolisierbare Energie des Futters und zeigte die Tendenz, die Stickstoff‐Retention zu vermindern. Résumé Recherches sur le taux optimum du manioc (Manihot esculenta Crantz) dans l'aliment des volailles La farine de manioc est obtenue de la manière suivante au Nigeria: les tubercules sont épluchés, séchés au soleil, moulus fin et tamisés sur un filet fin. La farine a été testée chez des poussins de 0–9 semaines et des poulets 10–20 semaines. Sur la base de l'accroissement, de l'appétence et de la mortalité, il a été possible de remplacer 10 % du maïs dans l'aliment par du manioc pour les poussins de 0–9 semaines, cela n'a par contre plus été possible avec les animaux de 10–20 semaines. Le manioc a diminué l'énergie métabolisable de l'aliment et a montré une tendance à diminuer la rétantion de l'azote. Resumen Estudios sobre el contenido óptimo de mandioca (Manihot esculenta Crantz) en piensos para pollitos La harina de mandioca se obtiene en Nigeria de la forma siguiente: se pelan los tubérculos, luego se secan al sol, se trituran hasta alcanzar el tamaño de un polvo fino y, a continuación, se tamiza por malla estrecha. Este ingrediente se probó en pollitos de raza roca blanca de 0–9 semanas de edad, y en otros de edades comprendidas entre 10 y 20 semanas. A la vista de los resultados respecto a aumentos ponderales, ingestión de pienso y mortalidad, la harina de mandioca puede reemplazar en los animales de 0–9 semanas de edad un 10 % de maíz en el pienso, mas no en la dieta de los animales en crecimiento. La yuyca reducía la energía metabolizable del pienso y tendía a disminuir la retención de nitrógeno en las aves.
