Review work was conducted to assess the climatic effect on livestock productions. Worldwide reviewers stated that the performances of animals are strongly correlated to environments. Currently climate change is a great challenge in the world. Intergovernmental panel meeting on climate change underlined that the poorest vulnerable groups are the worst and affected groups. Indirectly climate change has significant impact on feed resources on livestock productivity, carrying capacity of rangelands, and feeds, feeding options and grazing managements. Changed temperature increases the lignifications of plant tissues and reduces the digestibility and rates of degradations. Livestock is also directly exposed to tresses of the mortality, growth, reproduction and maintenances. Climatic change aggravates the water scarcity and accelerates the poverty level. The response of changing environments is increased. Water intake of Bos Indicus cattle was increased from about 3 kg DM intake at 10 °C to 5 kg at 30°C and to about 10 kg at 35°C. Climate change influenced other factors associated with vector populations and their distributions. Awareness creation on the consumption of livestock products related to environmental effects is important mitigation measures. The future directions of livestock production will be increased for the production of foods for the efficient transformation of livestock production to the international markets.
