Effects of Climate Change on Animal Breeding Objectives

The pressure of climate change on the livestock sector is increasing.When the climate change affect livestock sector, livestock sector also affect the climate change.The solution of this situation needs new approaches for livestock sector components such as feeding, husbandry and breeding.This review mainly focused on changing animal breeding objectives versus climate change effects.The problems related to the climate change the livestock sector face to face can be summarized as production performance, reproductive physiology, metabolism and the immune system.In that case, animal breeding objectives mainly covers these problems.Even the problems related to measuring the phenotypes relevant to adaptation must be overcome, animal breeding for climate change adaptation or mitigation will not be fundamentally different from existing breeding strategies.We focused on the animal breeding for enteric methane production, productivity and feed efficiency, disease resistance, and heat resistance.
