Breeding ewe lambs successfully to improve lifetime performance

Abstract

Ewe lambs have the ability to be successfully bred at 7-9 months of age. Breeding ewe lambs has a number of advantages including increased profitability and lifetime reproductive performance. However due to low and variable reproductive performance and the potential for negative effects on future performance, most ewe lambs are not bred. This review compares the differences in reproductive performance between ewe lambs and mature ewes. In addition, it summarises the known effects of ewe lamb breeding on lifetime performance. It also focuses on factors affecting the success of ewe lamb breeding. Lastly, it outlines the optimal management of the ewe lamb to the weaning of her first lamb and to maximise her lifetime performance
