Abstract

This research explores the energy usage and environmental effects of raising ostriches for meat and chickens for eggs. The findings from the energy analysis show that ostrich meat and egg production provide a more comprehensive comparison of energy consumption and production. The total energy consumption for meat and eggs is 1086825.54 and 1197794.25 MJ per 1000 pieces, respectively. In essence, egg production can be justified in terms of protein supply relative to total energy consumption for comparison with meat. This study also evaluates the impact of egg and meat production on human health. With a difference of 0.23 DALY, it is clear that egg production may have slightly greater negative effects on human health than meat production. These results indicate that egg production may be a more sustainable option compared to ostrich meat production in terms of energy use and environmental impacts. Further research is needed to investigate potential strategies for reducing the energy use and environmental impacts of ostrich meat production.
