There is paucity of information on utilization of sweet potato in feeding cockerels/cocks hence, this study examined the carcass
weight, hematology and spermatozoa quality of commercial cooks fed graded levels of sundried sweet potato whole tuber meal
(SSPWTM). Twenty cocks at 10 months old weighing about 2.5 kg were randomly allotted five per treatment designated as: D1
(0.0%), D2 (10%), D3 (15%) and D4 (20%). After 10 weeks of feeding, semen samples were collected by massage technique for semen
pH, active motile and live spermatozoa evaluations. Blood samples were collected by severing the jugular vein for hematological
evaluation and the dressed carcass was weighed to obtain carcass weight. Results indicated no statistical differences (P>0.05) in live
and dressed carcass weights, hemoglobin and platelet values among the treatments. Total relative testes volume, semen pH, active
motile and live spermatozoa values differed significantly (P<0.05) among the treatments. Live weight value was highest (2.64±0.06 kg)
in D2 followed by D4 (2.6±0.06 kg), D1 (2.58±0.06 kg) and D3 (2.56±0.05 kg). Dressed carcass weight value was highest in D1 and D2
with 2.3±0.06 kg followed by D4 (2.28±0.04 kg) and D3 (2.26 ±0.05 kg). Similar trend was observed in hemoglobin whereas, semen
pH value was highest (8.66±0.18) in D3 followed by D4 (8.28±0.38), D1 (8.22±0.41) and D2 (6.98±0.52). Active motile spermatozoa
values were 93.2±1.28%, 92.4±1.5%, 81.2±0.58% and 61.8±0.44% in D1, D4, D2 and D3 respectively. Live spermatozoa values were
94.4±1.5% (D1), 84.8±0.86% (D2), 84.2±3.17% (D4) and 71.6±5.1% (D3). Since the observed values were similar to those given in
normal cocks, SSPWTM could be utilized at 20% or more inclusion level in cocks nutrition.
