Technical note (TN747): Recording lamb traits

Posted in ,

Flock management and nutrition has a significant impact however, there is also a genetic factor to lamb survival making it possible to breed for improved lamb survival. Lambing ease, lamb vigour, lamb birth weight and ewe maternal ability all have a significant influence on lamb survival – selecting for these heritable traits will reduce mortality. These traits also have a significant impact on labour requirements. With less strain on the workforce at lambing, more lives can be saved, and there is opportunity to potentially reduce labour costs.
