Benefits of Farm Animals Genetic Adaptation: A Review

Abstract

The review aimed to review about the benefit of genetic adaptation of farm animals. Gene helps the farm animals to adapt conditions and able to survive in order to supply food sustainably for the fastest growing global human population. Furthermore, farm animal's genetic adaptation plays a great role to cope up climate change, environmental stresses including extreme hot and cold, disease and parasite and to overcome welfare problems. Accordingly, considering different factors, climatic condition, topography, breed type, relationship with human, disease and parasite resistance, welfare issue, physiological and behavioral status, nutritional habit in harsh environment and management influences, local and cross breeds are more important than exotic breeds to establish an international sustainable farm animal breeding program at farm and laboratory level. Likewise, in-situ and ex-situ adaptive local gene conservation bank should be done properly, especially, in developing countries where their experience is inadequate and local species record at regional level must be realized. Therefore, the importance of this review is unquestionable and must be documented.

Ruminant Livestock Production System Adaptation Strategies to Climate Change: A Review

“…The best mechanism to tolerate climate change is to rear local breeds adapted to harsh environments. Most developed country breeds have been studied for the past many decades in case the climate is managed [49]. The selection of animals is a cost-effective, cumulative, and permanent strategy that exploits natural variation among breeds for desirable traits.…”
