Abstract

Philippine agriculture is highly vulnerable to the adverse effect of climate change. The impact of climate change is often associated with the increase in temperature changes in precipitation and occurrence of extreme weather conditions which all can affect agricultural productivity, posing a grave threat to national food security. This study aims to contribute in addressing climate change agenda in the Philippines through assessment of impacts of climate change on the performance of livestock and poultry. In this paper, studies on broiler performance conducted during the past 5 years (2008-2013) were evaluated based on data availability, sufficiency, relevancy and length of records. A total of six studies conducted during the period of 2008 to 2013 were considered and hence used in the analysis. Performance parameters such as average daily gain, average daily feed intake and feed conversion ratio were taken and subjected to correlation analysis with prevailing environmental temperature (averaged over the duration of the studies). Broiler showed reduced performance as environmental temperature increases. The observed reduction in performance resulting from high ambient temperature illustrates the importance of providing these animals optimum environmental condition to ensure thermal comfort and production efficiency. The trend observed in the data suggest that temperature exceeding 25 deg C can be detrimental to broiler chicken and intervention such as additional cooling may be necessary to prevent decline in performance. However, the variability in the data indicates the needs for additional studies at different temperature levels. Moreover, future studies also include other environmental factors such as relative humidity. Results of such studies can be used in developing predictive models using thermal comfort indices such as temperature-humidity index. These models can be used in increasing the effects of different environmental conditions on productivity and profitability in poultry production, allowing poultry raisers to effectively manage ventilation and cooling systems to optimize productivity.
