Abstract:
Food availability is the most important issue that takes the priority places in the policies of all countries all over the world. Recently, more attention has been paid to livestock because of their ability to produce meat and milk, as well as it has a significant source of income for small holders and an economic contributor to the gross domestic product. Climate changes induced physiological stress, which is one of the complex factors making livestock management and husbandry challenging in many geographical locations in the world. Increased body temperature or heat stress will cause production losses in livestock and impact on their ability to maintain normal function. There is considerable research evidence that showed significant decline in animal performance when subjected to heat stress. Heat stress inflicts heavy economic losses on livestock production. The effects of heat stress is evident in feed consumption, production efficiency in terms of milk yield or weight gain per unit of feed energy, growth rate, and reproductive efficiency. The aim of this article is to discuss increasing food production to ensure food security for nearly 8 billion people, without causing further environmental damage that can be achieved by transforming systems and adopting sustainable livestock practices within a changing climate.
