ResumoPoultry plays a vital role in the livelihood of rural households in Africa, especially Nigeria [1].Poultry are birds which render economic services to humans as a primary supplier of meat, egg and raw materials to industries (feathers, waste products), source of income and employment to people compared to other domestic animals [2].Poultry convert feed to egg and meat within a short period of time [3].Developing the poultry industry in Nigeria will be the fastest means of bridging the protein deficiency gap prevailing the country [4].Whenever ambient temperature is high, chickens tend to have higher energy needs than when in thermo-neutral environments.Major losses result from a less efficient conversion of feed to meat; this also affects poultry health and productivity [5].Poultry flocks are particularly endangered to climate change due to a range of thermal conditions which affects the animals' behavioural and physiological activities [1].Hence, birds can only tolerate lowly temperature ranges to sustain the peak of their production for human consumption.The environmental conditions affecting the performance of chicken include temperature, relative humidity and light at a given time [6].Ambient temperatures significantly influence the survivability and performance of the poultry production [2].Ahaotu., et al. [7] stated that as the ambient temperature increased to 34 o C, the mortality due to heat will be due to seasonal fluctuations depend upon the temperature difference between the bird and its environment [10].
