Likewise, domesticated animals are so dependent upon man that in his absence their very existence would be jeopardized to the point where they would not thrive and some would fail to survive. Artificial insemination (AI) - one of the most important techniques ever devised for the genetic improvement of farm animals - is a widely used tool for livestock breeding and management programs and is a process by which sperm are collected from the male, processed, stored and artificially introduced into the female reproductive tract for the purpose of conception. A male animal produces millions of sperms daily. Theoretically, it can inseminate females regularly and produce several offsprings. Artificial insemination is used instead of natural mating for reproduction purposes. This is when a male animal, for example, a bull, is kept with a herd of cows and ‘covers’ (copulates with) them when they are ready to mate (in oestrus) so the bull’s semen fertilizes the cow’s eggs to produce calves. Fertilization can take place away from the bull and the two animals do not even meet! Although AI (in the form of intrauterine insemination) is not frequently used in human patients, it is the most commonly used method of breeding food production animals in developed countries, with more than 90% pigs and almost the same proportion of dairy cattle bred by this method in the European Union and North America. In the actual procedure used, semen is obtained from a male animal and, after being diluted, is deep-frozen, after which it can be stored for long periods of time without losing its fertility. For use, the semen is thawed and then introduced into the genital tract of a female animal. The first successful experiment with artificial insemination in animals was performed by an Italian physiologist Lazzaro Spallanzani, who in 1780, while investigating animal reproduction, developed a technique for artificial insemination in dogs. This approach was refined in the 1930s in Russia, and the subsequent development of methods for the cryopreservation (preservation through freezing) of semen led to the widespread use of AI in animals. There are many advantages to artificial insemination (AI) in domesticated and zoo animals, such as smaller chance of injury to either partner during the mating process, X Preface less stress to the female, who is often the one that has to be transported to and from the home of the male, but one should keep in the mind that the system of reproduction is perfect, including artificial insemination. The chief priority of artificial insemination is that the desirable characteristics of a bull or other male livestock animal can be passed on more quickly and to more progeny than if that animal is mated with females in a natural fashion. Ten thousand or more calves are produced annually from a single bull through the use of artificial insemination. Artificial insemination has been most widely used for breeding dairy cattle and pigs and has made bulls of high genetic merit available to all. It has been used to facilitate the reproductive success and conservation of threatened or endangered animals. Although AI (in the form of intrauterine insemination) is not frequently used in human patients, it is the most commonly used method of breeding food production animals in developed countries, with more than 90% pigs and almost the same proportion of dairy cattle bred by this method in the European Union and North America. Examples of wild animals that have been successfully impregnated through artificial insemination include big cats (e.g., the tiger, the puma, the cheetah, and the clouded leopard), the white rhinoceros (Ceratotherium simum) and the onager (Equus onager). This book contains under one cover 16 chapters of concise, up-to-date information on artificial insemination. AI in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs will be detailed in different chapters. Cryopreservation effect on sperm quality and fertility, new method and diagnostic test in semen analysis, management factors affecting fertility after cervical insemination, factors of non-infectious nature affecting the fertility, fatty acids effects on reproductive performance of ruminants, particularities of bovine artificial insemination, sperm preparation techniques and reproductive endocrinology diseases will be described in these chapters. The purpose of this book is to provide, as both a college text book and a reference source, a comprehensive text that contains current information on artificial insemination. This book is not a presentation of concepts of artificial insemination with an extensive list of references, but rather a consensus of important information with key references to allow the reader to further explore the artificial insemination field. This book will deal with the use of artificial insemination (AI) in animals, currently and in the future, with particular emphasis on comparative aspects between species. This book will explain the advantages and disadvantages of using AI, the various methodologies used in different species, and how AI can be used to improve reproductive efficiency in farm animals. I hope this book will be used worldwide as a college textbook and authoritative reference book for research and extension specialists, AI practitioners, teachers and students. [...]... reproductive tract in these species presents more of a barrier to successful insemination than in cattle, since the cervix is tightly folded, making insertion of the insemination catheter difficult Productivity in sheep and goats could be increased, by improving the quality of the spermatozoa assigned for use in AI, and improving the AI techniques in these species Recent innovations in sheep breeding include...
