Case Studies on Reproductive Activity of Equines in Relation to Environmental Factors in Central Ethiopia


Book Description

The effect of environmental factors is becoming more significant in animal reproduction under the tropics. This thesis presents a study of the relationship between the circannual reproductive pattern of tropical female equines and environmental factors believed to influence reproduction such as climate, nutritional status and management. The thesis contains 7 chapters including introduction, literature reviews, materials and methods, results, discussion, and conclusions and recommendations. Reproductive activities of jennies and mares (as measured by follicular activities, manifestation of oestrus and incidence of ovulation) were studied using serial ultrasonography, observational study and progesterone assay through three distinctly different seasons. Data were collected on nutritional status, management systems and climate to establish relationships with reproductive pattern. Results are presented in detail in tabulations, figures, and graphics. The findings are discussed and summarized with conclusive remarks. Recommendations on future study prospects are also given.




Animal Trade Histories in the Indian Ocean World


Book Description

This book examines trades in animals and animal products in the history of the Indian Ocean World (IOW). An international array of established and emerging scholars investigate how the roles of equines, ungulates, sub-ungulates, mollusks, and avians expand our understandings of commerce, human societies, and world systems. Focusing primarily on the period 1500-1900, they explore how animals and their products shaped the relationships between populations in the IOW and Europeans arriving by maritime routes. By elucidating this fundamental yet under-explored aspect of encounters and exchanges in the IOW, these interdisciplinary essays further our understanding of the region, the environment, and the material, political and economic history of the world.




Equine Reproductive Physiology, Breeding and Stud Management, 5th Edition


Book Description

Equine Reproductive Physiology Breeding and Stud Management, 5th Edition provides a thorough grounding in equine reproductive anatomy and physiology and applies it to all aspects of breeding and stud management. This includes detailed coverage of the management of mares, stallions and foals, as well as stud management practicalities such as infertility, artificial insemination and advanced reproductive techniques. This textbook, which has been updated throughout with additional material and references, continues to provide an authoritative treatise on equine reproduction for students, practising veterinary surgeons and stud managers.




Equids--zebras, Asses, and Horses


Book Description

The new Equid Action Plan provides current knowledge on the biology, ecology and conservation status of wild zebras, asses, and horses. It specifies what information is lacking, and prioritizes needed conservation actions. The Action Plan also provides chapters on equid taxonomy, genetics, reproductive biology, and population dynamics. These chapters highlight unsolved issues of taxonomy and genetics. They also provide information and insight into the special demographic and genetic challenges of managing small populations. The chapter on disease provides a review of documented equine disease and epidemiology and focuses on priorities for equid conservation health. The final chapter deals with the importance of developing an assessment methodology that explicitly considers the role of equids in ecosystems and the ecological processes that are necessary for ecosystem viability. The approach of combining ecological field studies and ecosystem modeling should prove useful for the scientific management and conservation of wild equids worldwide. These chapters provide research and conservation practitioners with new information and paradigms.







Protozoal Abortion in Farm Ruminants


Book Description

This book contains guidelines for the diagnosis and control of protozoal reproduction losses in farm ruminants. This book is comprised of 5 chapters covering the following: reproductive problems in cattle and sheep; sample collection; aetiological diagnosis; differential diagnosis of protozoal abortion in farm ruminants; and control measures.




Ostrich Production Systems


Book Description

A comprehensive review of all aspects of ostrich production including a series of case histories from some countries that farm ostriches commercially: important countries such as South Africa, Namibia and Zimbabwe; newly re-emerging industries such as Australia; and countries where production is less developed, such as Kenya, Ethiopia and the United Arab Emirates (UAE).




Environmental Consequences of the Chernobyl Accident and Their Remediation


Book Description

The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.




The Welfare of Horses


Book Description

This book describes the development of horse behaviour, and the way in which the management of horses today affects their welfare. Horses for sport, companionship and work are considered and ways of improving their welfare by better training and management is described. The book assesses welfare, nutrition, and behaviour problems with horses. The authors include internationally-recognised scientists from Britain, Ireland, USA and Australia.




Breeding Strategies for Sustainable Management of Animal Genetic Resources


Book Description

Genetic improvement is an essential component of the management of animal genetic resources and can make important contributions to food security and rural development. Yet, the majority of developing countries have not been successful in sustaining breed development programmes. The objective of these guidelines is to help countries plan and develop effective genetic improvement programmes and to maximize the chances that such programmes will be sustained. These guidelines address Strategic Priority Area 2 of the Global Plan of Action for Animal Genetic resources adopted in 2007, and are intended for use by policy-makers and organizations involved in livestock development.
