Abstract
This paper describes three strategies to improve the reproductive performance of small ruminants
in ways that lead to ?clean, green and ethical? animal production. The first is aimed at control of the
timing of reproductive events for which we turn to the socio-sexual inputs of the ?male effect? to
induce synchronised ovulation in females thatwould otherwise be anovulatory. The second strategy,
?focussed feeding?, is based on our knowledge of the responses to nutrition and aims to develop
short programs of nutritional supplements that are precisely timed and specifically designed for
individual events in the reproductive process, such as gamete production, embryo survival, fetal
programming and colostrum production. The third strategy aims to maximise offspring survival
by a combination of management, nutrition and genetic selection for behavior (temperament). All
of these approaches involve non-pharmacological manipulation of the endogenous control systems
of the animals and complement the detailed information from ultrasound that is now becoming
available. The use of such clean, green and ethical tools in the management of our animals can be
cost-effective, increase productivity and, at the same time, greatly improve the image of meat and
milk industries in society and the marketplace.
