Carcass Characteristics, Organ Proportion and Economics of Broiler Chickens Fed Graded Levels of Processed Manihot esculentum crantz (var. Umucass 36) Cassava Composite Meal
Abstract
One week old one hundred and fifty (150) Arbor Acre broiler chickens were used to determine the
effect of feeding cassava composite meal as replacement for both maize and soya bean in broiler
chickens diets, on their carcass characteristics, organs proportion and economics of production.
The harvested cassava roots were washed, peeled, grated, dried and toasted into ‘gari’, the leaves,
petioles (which formed the leaf meal) and tender stems were also chopped and oven dried. The
cassava composite meal (CCM) was a mixture of the root meal, foliage meal and the tender stem
meal. The birds were randomly assigned to five treatment diets replicated into three with ten birds
per replicate in a Completely Randomized Design. Five diets were formulated and designated D1
(control) to D5. Anti-nutrients like Hydrogen cyanide and Pytate did not follow a particular
pattern while Tannin and Trypsin inhibitor decreases with increasing levels of CCM. The antinutrients
in the diets were within the tolerable level for broiler chickens. Broilers on diet D2 having
5% inclusion level of CCM was better in carcass characteristics. Diets D3, D4 and D5 with higher
inclusion level of CCM had heavier weights of heart, liver, gizzard, small intestine and abdominal
fat compared to the control diet. Broilers on Diet D2 were the costliest to produce but gave the
best revenue and gross margin. From the fore going it could be concluded that five percent level
of inclusion UMUCASS 36 composite meal can replace both maize and soybean for optimal
performance of broiler chickens.
