Book Description
Reproductive wastage is a major economic burden in sheep production globally, especially within Australia as livestock production systems face increased pressure from climatic variability (e.g. prolonged droughts or flooding). Sheep are sensitive to acute changes in their environment such as heat stress, which if not adequately monitored will result in significant production losses such as reproductive failure, increased parasite and worm burden, morbidity and mortality risks. Through basic and applied research in the areas of stress and reproductive physiology our team has made significant advancements in the understanding of sheep behaviour and physiological responses to acute and chronic stressors. Using minimally invasive hormone monitoring technology in combination with field based assessment of sheep health and productivity traits, our team has delivered new knowledge on how sheep react to acute environmental stress and how it impacts on sheep reproduction. In this chapter, we evaluated the fertility rates and embryo quality of Merino ewes under AI breeding program. We discuss factors such as heat stress that can impact on ewe and offspring quality.

Book Description
Genetics of Reproduction in Sheep is a compilation of papers that are concerned with the study and application of genetics to the reproduction in sheep. The book is divided into six parts, grouping the papers according to topic. The main topics include genetic variation and selection; the inheritance and the effects of the Booroola gene; genetic strategies for single genes; physiology of genetic variation; the physiological criteria of genetic merit; and the national requirement and systems of husbandry. The text is recommended for those involved with raising sheep and plan to apply genetics in their reproduction, as well as for geneticists who wish to conduct studies on how their field is applied to sheep reproduction.

Book Description
Although intensive husbandry is increasingly applied to sheep, most sheep production around the world is still based on the extensive system. Under these conditions, attempts to improve productivity must take particular account of reproductive and developmental behaviour, as successful sheep production depends heavily on optimal reproduction and development. These topics are presented in this anthology of selected publications on sheep behaviour. The papers have been taken from ten years of Applied Animal Ethology (now Applied Animal Behaviour Science) from its inception in December 1974 to the end of its publication under that title in 1984.

Book Description
First published in 1984, this volume comprised a broad synthesis of contemporary research on sheep reproduction conducted in Australia. Australia is internationally recognized for the excellence of its research in this field, and heads the world in areas of the neuro-endocrine control of reproduction, reproductive behaviour, artificial insemination and manipulation of reproductive performance, to name just a few. The book comprises some 23 review papers and short communications, all refereed by experts in the field, covering such topics as neuro-endocrinology, sexual behaviour, testicular and ovular function, pregnancy and foetal growth, parturition, lamb survival, nutrition and genetics. Advanced methods, developed in the seventies and early eighties to control reproductive function, gene manipulation and intra-uterine insemination are also considered, together with the managerial and economic values of such developments.
