    Herbal supplementation during climatic stress could alleviate neuronal cell damage, prevent tissue retention of synthetic pharmaceuticals and enhance better health status of animal product consumers. Incidence of global warming has adversely influenced animal health and reproductive performance more prominently under tropical climate. t lycopene and African walnut leaf extract (AWLE) have been proven to contain bioactive components with antioxidant capability needed to improve seminal plasma biochemical indices of cockerels under tropical environment. This study was conducted to determine the effect of lycopene and AWLE on seminal plasma biochemistry indices heat-stressed cockerels 30-weeks old cockerels (n=54) were used for this experiment (10 weeks) with treatments stated as follows; Group 1 – 250ml of water, no inclusion (control), Group 2 – 7.5ml of lycopene/250ml of water, Group 3 – 15ml of lycopene/250ml of water, Group 4 – 7.5ml of AWLE/250ml of water, Group 5 – 15ml of AWLE/250ml of water, Group 6 – 7.5ml of lycopene+7.5ml of African walnut leaf extract/250ml of water, Group 7 – 15ml of lycopene+15ml of leaf extract/250ml of water, Group 8 – Vitamin C 0.1g/250ml of water, Group 9 – Cold temperature and 250mls water. The table of result is as shown in Table 1. Observation showed that cockerels under group 5 experienced a significantly depressed Malondialdehyde (0.61±0.09U/mg), while showing significant (P<0.05) elevation in seminal catalase value (741.27±21.01U/mg). It was also noted total protein value (9.75±0.23mg/dl) was significantly (P<0.05) increased under group 9, which is statistically similar with values recorded for groups 4 and 8. A reduction in MDA value and an increase in catalase under group 5 could be due to the influence of bioactive components present in AWLE. Seminal plasma proteins (SPP) enhance sperm protection, transport and fertility via improved capacitation and acrosome reaction.
