Abstract
This study was conducted to assess the relative organ weight and testes
histopathology of heat-stressed cockerels given &lycopene and African
walnut (Tetracarpidium conophorum Mull. Arg. Hutch & Dalziel.) leaf extract
(TCLE). Thirty week (30-week) old cockerels (n=54), were used for this
experiment. They were randomly grouped into nine treatments containing: 0
ml of extract / 250 ml of water (control) (T1), 7.5 ml of lycopene / 250 ml of
water (T2), 15 ml of lycopene / 250 ml of water (T3), 7.5 ml of TCLE / 250 ml of
water (T4), 15 ml of TCLE / 250 ml of water (T5), 7.5 ml of lycopene + 7.5 ml of
TCLE / 250 ml of water (T6), 15 ml of lycopene + 15 ml of TCLE / 250 ml of
water (T7), Vitamin C 0.1 g per 250 ml of water (T8), Cold temperature + Cold
water (5-7OC) (T9). The result showed that there was non-signicant effect
(P>0.05) of lycopene and TCLE on all the relative organs weight values
recorded. Testes of the cockerels given the control treatment (T8) had
abnormal widening of interstitial spaces and degeneration of interstitial cells
and lumen. For cockerels on T2 diets, there was an increase in both the
interstitial spaces and intracellular spaces of the seminiferous tubules.
Cockerels given T7 showed appreciable normal histomorphology with
increased interstitial spaces and intracellular spaces of the seminiferous
tubules. Cockerels under T8, given Vitamin C, showed abnormal widening of
interstitial spaces and degeneration of interstitial cells of the seminiferous
tubules. Normal appearance without abnormal widening of interstitial spaces
and degeneration of interstitial cells in cockerel given T9. In conclusion, 15 ml
of lycopene + 15 ml of TCLE / 250 ml of water (T7) can be administered to
cockerels in a cool environment, with an addition of cold water (T9), to give a
better testicular structure, and 15 ml of lycopene / 250 ml for improved
internal organ weight.
