This study considered the inclusion of carcass attributes in breeding objectives and selection criteria developed for pasture-fed Uruguayan production systems for beef cattle, based on British breeds. Correlated responses in dressing percentage (DP),

Summary Female fertility traits are key components of the profitability of beef cattle production. However, these traits are difficult and expensive to measure, particularly under extensive pastoral conditions, and consequently, fertility records are
