Download or read book Animal Models and Human Reproduction written by Heide Schatten and published by John Wiley & Sons. This book was released on 2017-03-20 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our knowledge of reproductive biology has increased enormously in recent years on cellular, molecular, and genetic levels, leading to significant breakthroughs that have directly benefitted in vitro fertilization (IVF) and other assisted reproductive technologies (ART) in humans and animal systems. Animal Models and Human Reproduction presents a comprehensive reference that reflects the latest scientific research being done in human reproductive biology utilizing domestic animal models. Chapters on canine, equine, cow, pig, frog, and mouse models of reproduction reflect frontier research in placental biology, ovarian function and fertility, non-coding RNAs in gametogenesis, oocyte and embryo metabolism, fertilization, cryopreservation, signal transduction pathways, chromatin dynamics, epigenetics, reproductive aging, and inflammation. Chapters on non-human primate models also highlight recent advancements into such issues as human in vitro fertilization (IVF) and assisted reproductive technologies (ART). This book offers animal scientists, reproductive biology scientists, clinicians and practitioners, invaluable insights into a wide range of issues at the forefront of human reproductive health.

Book Synopsis Human Chorionic Gonadotropin and Gonadotropin-releasing Hormone Influence Pregnancy Survival and Resynchronized Ovulation Before Timed Artificial Insemination in Holstein Cattle by :
Download or read book Human Chorionic Gonadotropin and Gonadotropin-releasing Hormone Influence Pregnancy Survival and Resynchronized Ovulation Before Timed Artificial Insemination in Holstein Cattle written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was performed to determine the minimum effective dose of human chorionic gonadotropin (hCG) needed to induce ovulation of follicles in cattle (Exp. 1). Another study determined the effects of replacing the first injection of GnRH (d -7) with hCG or saline in a Resynch-Ovsynch protocol [injection of GnRH 7 d before and 48 h after PGF[subscript2alpha] before a resynchronized fixed-timed AI (TAI)] on pregnancy rates in cows diagnosed not pregnant and pregnancy survival in cows diagnosed pregnant (d 0; Exp. 2). A final study determined the ovulation potential of hCG compared with GnRH and saline (Exp. 3). In Exp. 1, ovaries of Holstein cows were mapped by using transrectal ultrasonography 7 d before pregnancy diagnosis. Cows were assigned to treatments of saline, 100 [Mu]g of GnRH, or 500, 1,000, 2,000, or 3,000 IU of hCG. Ovarian structures were monitored 7 d later and proportion of cows and follicles that ovulated were recorded. In Exp. 2, cows in 4 herds were assigned to treatments of 1,000 IU of hCG, 100 [Mu]g of GnRH, or left as untreated controls 7 d before pregnancy diagnosis. Nonpregnant cows were given PGF[subscript2alpha] (d 0), then inseminated 72 h later, concurrent with a GnRH injection. Pregnancy rates tended (P = 0.08) to be increased by GnRH (17.9%; n = 703) compared with control (12.9%; n = 505), but not hCG (16.5%; n = 541). Incidences of ovulation in nonpregnant cows (Exp. 3) were: hCG (51.6%; n = 126), GnRH (46.1%; n = 102), and control (28.1%; n = 96), whereas those in pregnant cows were: hCG (59.3%; n = 59), GnRH (24.5%; n = 49), and control (6.9%; n = 58). We concluded that: 1) a minimum dose of 1,000 IU of hCG resulted in a greater ovulatory response than saline, GnRH, or 500 IU of hCG (Exp. 1); 2) initiating a Resynch-Ovsynch protocol 7 d before pregnancy diagnosis with saline reduced timed AI pregnancy rates (Exp. 2); and 3) incidence of new CL was greater after hCG than GnRH in pregnant cows, but not in nonpregnant cows (Exp. 3).

Book Synopsis Regulation of Implantation and Establishment of Pregnancy in Mammals by : Rodney D. Geisert
Download or read book Regulation of Implantation and Establishment of Pregnancy in Mammals written by Rodney D. Geisert and published by Springer. This book was released on 2015-10-08 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades technological advances in transcriptomics, proteomics, metabolomics, and glycomics along with the ability to selectively knockout genes of interest has greatly advanced our understanding of maternal-conceptus interactions that are essential for the establishment and maintenance of a successful pregnancy. This knowledge provides a foundation from which to build research endeavors to help resolve infertility, embryonic loss and recurrent abortion in humans, captive wild animals and important farm species. The present volume on “Regulation of Implantation and Establishment of Pregnancy in Mammals” brings together current reviews from leading experts to address the diversity of mechanisms by which species establish and maintain pregnancy. Implantation in rodents, dogs, pigs, cattle, sheep, horses, primates, humans and embryonic diapause in wild species are discussed. Reviews will provide current knowledge on the role of endometrial steroid receptors, adhesion factors, cytokines, interferons, steroids, prostaglandins, growth factors and immune cells involved with regulation of conceptus development.

Book Synopsis Reproduction in Cattle by : Peter J. H. Ball
Download or read book Reproduction in Cattle written by Peter J. H. Ball and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cattle play a fundamental role in animal agriculture throughout the world. They not only provide us with a vital food source, but they also provide us with fertilizer and fuel. Keeping reproduction levels at an optimum level is therefore essential, but this is often a complicated process, especially with modern, high yielding cows. Written in a practical and user-friendly style, this book aims to help the reader understand cattle reproduction by explaining the underlying physiology of the reproductive process and the role and importance of pharmacology and technology, and showing how management techniques can improve reproductive efficiency. This edition includes: Recent research findings on the physiology of the oestrous cycle and its control; New techniques for monitoring and manipulating reproduction, including pregnancy diagnosis and embryo transfer; Advice on identifying common infertility problems and how to prevent and treat them. Reproduction Cattle 3e is essential reading for veterinary and agricultural students, as well as veterinarians and farmers involved in cattle reproduction.

Download or read book Environmental Physiology of Livestock written by R. J. Collier and published by John Wiley & Sons. This book was released on 2012-02-07 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental stress is one of the most significant factors affecting livestock performance and health, and it is only expected to increase with effects of global warming. Environmental Physiology of Livestock brings together the latest research on environmental physiology, summarizing progress in the field and providing directions for future research. Recent developments in estimating heat stress loads are discussed, as well as key studies in metabolism, reproduction, and genetic expressions. Environmental Physiology of Livestock begins with a survey of current heat indexing tools, highlighting recent discoveries in animal physiology, changes in productivity levels, and new technologies available to better estimate stress response. Using this synopsis as a point of orientation, later chapters hone in on major effects of heat stress, including changing metabolic pathways and nutrient requirements, endocrine regulation of acclimation to environmental stress, and reduced reproductive performance. The text concludes with a thorough discussion of environmental effects on gene expressions, providing important insight for future breeding practices. Environmental Physiology of Livestock is a globally contributed volume and a key resource for animal science researchers, geneticists, and breeders.
