Abstract
The effects of climate change, especially global warming, can greatly affect the production performance and health of animals around the world. The national average temperature has increased by 1°C since 1970. Most livestock owners in the country feel that weather change is affecting farm animal production and health. The main impacts of weather change on animal production include feed shortages, water shortages, reduced livestock genomic resources, decreased productivity, and reduced mature weight and/or longer time to reach mature weight based on their significance. High temperatures resulting from environmental alteration may increase the level of development of few pathogens or parasites that found one or more life cycle levels outside the mammalian host. Besides, the spatial disposition and visibility of pasture and water are largely depending on the pattern and visibility of rainfall. Food and water shortages bestow to deduced livestock abundance and reproductive execution. These include slow growth rate of animals, loss of body condition, decreased milk yield, and poor reproductive performance of mature animals. Drought bulls that are debilitated and in poor physical condition cannot provide sufficient drought energy for plowing and thus hinder crop cultivation. Bush encroachment, as well as population pressure, leads to reduced availability of good pastures thus environmental change will have far-reaching consequences for animal yield and health, especially in vulnerable parts of nature where it is essential for nutrients and maintenance. Once more, the environmental change affects farm animal health through various mechanisms; which are effects on parasites, effects on hosts, and vectors, such as alters in precipitation and temperature schemes that can influence both the placement and ample of disease careers; and effects on micropaleontology, such as alteration of transmission levels between hosts. This study has focused to investigate the inherent impacts of environmental alteration on livestock health and productivity.
