Publisher's Synopsis
AI has become one of the most important techniques ever devised for the genetic improvement of farm animals. It has been most widely used for breeding dairy cattle and has made bulls of high genetic merit available to all. The great increase in the use of artificial insemination for dairybreeds of cattle during recent years has been fully justified by the satisfactory results achieved through thorough study of, and careful attention to, proper methods for collection of semen and its transfer to females. Considerable time can now be saved in proving young bulls, and the number of progeny from outstanding herd sires can be increased. There are a few disadvantages of AI which can be overcome through proper management. A human detection of heat is required. Success or failure of AI depends on how well this task is performed. AI requires more labor,facilities and managerial skill than natural service. Proper implementation of AI requires special training, skill and practice. Those undertaking this work must be familiar with the anatomy and physiology of the reproductive organs of cattle and have a sound understanding of correct sanitary precautions and the numerous opportunities that exist for doing .irreparable damage This book entitled 'Veterinary Andrology and Artificial Insemination inFarm Animals' is intended to focus on andrology, puberty, sexual maturity, sexual behaviour and libido in domestic animals. It covers state of the art information on artificial insemination in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs. new methods and diagnostic techniques insemen 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 ofbovine artificial insemination, sperm preparation techniques and repro.ductive endocrinology diseases are described In the last decade, the use of sex-sorted bovine sperm has been widely incorporated in commercial beef and dairy operations, depending on management strategy and geographic location. Artificial insemination (AI) was the first great biotechnology applied to improve reproduction and genetics of farm animals. It has had an enormous impact worldwide in many species, particularly in dairy cattle. The possibility of increasing the production of calves of a desired sex has important economic implications for beef and dairy industries worldwide. For instance, dairy producers can now produce greater numbers of replacement heifers to offset poor fertility and high culling rates in modern lactating herds. Likewise, for beef producers, efficiently increasing the proportion of male calves relative to cohort females is economically favorable. As a result, the cattle industry worldwide has become increasingly interested, and in some geographic regions, heavily dependent on sex-sorted sperm.
