Abstract

In a feeding trial that lasted 56 days (8 weeks), cassava root-leaf meal mixture (CRLMM) was evaluated as a replacement for maize in broiler starter and finisher diets. Five experimental diets were formulated in which maize was replaced with 0%, 25%, 50%, 75% and 100% CRLMM for treatments 1, 2, 3, 4 and 5 respectively. All the experimental diets were pelletised. Thirty (30) birds were assigned to each of the treatment diets in randomised complete block design and each treatment was replicated thrice with 10 birds per replicate. The birds (Marshall Broiler chicks) were 7 day old at the inception of the experiment. The experimental starter and finisher diets were fed ad libitum. Data were collected for blood parameters and Carcass characteristics. The haematological indices showed a significant difference (P<0.05) in mean corpuscular haemoglobin concentration (MCHC). The carcass characteristics showed a significance difference (P<0.05) in slaughter weight, plucked weight, dressing percentage, thigh cut, back cut and in organs such as heart, lungs, spleen, gut weight, gut length and caecal length. The remaining body components and organs did not show any significant difference (P>0.05). CRLMM showed a good promise when included in the diets of broiler starter and finisher up to 75% without a harmful effect on haematology and carcass characteristics of broilers reared in the northern guinea savannah. It can be recommended that 75% of maize can be replaced with CRLMM in broiler diets in Mubi and environs.
