Climate change is posing a challenge not only to agricultural crops but also to livestock. In order to sustain rural livelihoods, it is critical to identify livestock breeds that are climate resilient. In this direction, Indian scientists have identified two variables which could be used to assess resilience capacity of indigenous breeds of goats.
