    Abstract

    In the development of 'clean, green and ethical' systems for sheep management, we can reduce our dependence on hormones
    for controlling reproduction by using pheromones from novel rams to induce ovulation (the 'ram effect'). With a view to improving the efficiency of the 'ram effect', we tested whether nutritional supplementation of the ewes would improve their responses. Supplementation did not increase the proportion of the ewe flock that ovulated or showed normal cycles. However, there was an increase In the frequency of multiple ovulations when supplementation was sustained well into the preovulatory stage of the ram induced oestrous cycle.
