Extract

Hill sheep breeds are required to survive and rear lambs in harsh conditions, and good maternal characteristics contribute to their success. However, improved carcass characteristics are also required to meet market requirements. This paper evaluates lamb performance characteristics after 4 years of selection using indexes tailored to improve overall productivity in different hill sheep production systems.
