Effect of Climate Change on Poultry Egg Production in Ogun State, Nigeria

Abstract

Climate change is posing serious threat to poultry production and consequently affecting the profit of poultry farmers. This study examined the effect of climate change on poultry egg production in Ogun State, Nigeria. Secondary data on egg output in Ogun state from 1990 to 2019 was collected from National Bureau of Statistics (NBS) and time series data on amount of rainfall, temperature
and relative humidity from 1990 to 2019 were also collected from Nigeria Meteorogical Agency, (NIMET). Trend analysis was carried out to examine the trend of climatic events over the years. Statistical result of climatic variables (rainfall, temperature and relative humidity) showed an increasing trend, although there is large variability (301.43 mm) in the amount of rainfall from year to year while temperature and relative humidity shows slim (2.118°C) and average (5.588%) variability respectively. The result of the linear  regression shows that rainfall and relative humidity were positively related to egg output, however, rainfall was not significant.  Temperature was negative and significant at 10 percent level. The study recommends that extension agents should be empowered with training on climate change adaptation strategies in order to build capacity of poultry farmers and introduce adaptation technologies that will ensure improvement in egg production.
