    Abstract

    Feeding lupin grain to ewes for a week prior to ovulation increased ovulation rate while feeding immediately prior to ovulation did not affect ovulation rate. Feeding a diet high in omega-6 fatty acids around conception was associated with a higher proportion of female lambs. Implementation of these nutritional strategies offers sheep producers viable means of increasing the number of lambs born and the ability to target specific markets that favour male or female offspring, resulting in substantial productivity benefits.
