This book was released on 1988 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to investigate the effects of gonadotropin-releasing hormone (GnRH), administered twice during the same estrous cycle, on bovine luteal function. Eight mature beef cows, each cow serving as her own control, were injected intravenously (i.v.) with saline on days 2 and 8 of the cycle (day of estrus=day 0 of the cycle), then with 10Oug GnRH on days 2 and 8 of the subsequent cycle. Jugular blood samples were taken immediately prior to an injection and at 15, 30, 45, 60, 120 and 240 min postinjection to characterize changes in serum luteinizing hormone (LH). Blood was also collected on alternate days after an injection until day 16 of the cycle, to characterize serum progesterone levels. Treatment with GnRH did not significantly alter serum progesterone concentrations. Although GnRH caused release of LH on days 2 and 8, the quantity of LH released was significantly greater on day 8 (P

This book was released on 1985 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to evaluate the effects of gonadotropin releasing hormone (GnRH) on the function of the bovine corpus luteum during the estrous cycle. In Experiment 1, 10 heifers were assigned randomly into two groups with each heifer serving as her own control. Heifers in Group I (n=5) were injected intravenously (iv) with vehicle (saline) on day 2 of the cycle (day 0=day of estrus) followed by an iv injection of 100 ug GnRH on day 2 of the subsequent estrous cycle. Group II (n=5) heifers were similarly treated except injections were given on day 10 of the estrous cycle. All heifers were bled via the jugular vein at 15 minute intervals beginning 30 minutes prior to injection and for 3 hours after injection. Blood samples were also taken on alternate days after injection through day 16 of the cycle. Gonadotropin releasing hormone caused a significant release of luteinizing hormone (LH) on both treatment days with the peak occurring at 15 to 30 minutes postinjection. Treatment with GnRH on either day 2 or 10 of the cycle caused a reduction in serum progesterone levels on days 12, 14 and 16 of the cycle (Group I, control 3.99, 3.97, 4.07 vs treated 2.63, 3.45, 2.87; Group II, control 3.18, 3.82, 4.13 vs treated 2.50, 2.82, 3.17 ng/ml, respectively, P

Available in PDF, EPUB and Kindle. Book excerpt: New techniques in cellular and molecular biology have increased our understanding of the mechanisms controlling reproductive function in the female. Emphasizing these new techniques, Molecular Biology of the Female Reproductive System provides a state-of-the-art review of local regulatory mechanisms that control reproductive processes. Stressing the interface of endocrinology, immunology, and cell biology, this book concentrates on the autocrine, paracrine, and endocrine systems that regulate both the functions of the ovary and uterus and the interaction between the early embryo and the mother. - Covers the mechanisms controlling reproductive function in the female - Offers a cellular and molecular approach to the control of reproductive function - Focuses on the ovary and uterus, and includes a discussion of the early embryo, including - Hormonal control of folliculogenesis and luteal function - Cell-cell interactions in the follicle - Role of cytokines in regulating steroid and protein hormone production - Endocrine receptors and mechanisms in ovulation - Cell biology of the oviduct and uterus - Migratory cells - Paracrine regulation - Hormones of the trophectoderm and early placenta - Interaction between trophectoderm and endometrium - Provides extensive references

Available in PDF, EPUB and Kindle. Book excerpt: ​This book describes the life cycle of a unique endocrine gland that is absolutely essential for the establishment and maintenance of pregnancy in all mammalian species. The corpus luteum is unique because it is formed and destroyed every (non-fertile) reproductive cycle. When fertilization occurs, the corpus luteum is rescued or maintained. The processes that control corpus luteum formation, demise (luteolysis), or maintenance are just beginning to be unraveled in recent years; they involve diverse cell types and mechanisms. Some of these processes resemble tumor development—angiogenesis, for instance—but interestingly enough, this resemblance is only up to a point. The corpus luteum uses mechanisms that allow its normal, physiological growth and disappearance. Pulling together key research on the corpus luteum, this volume is of interest to both reproductive endocrinologists and comparative physiologists, with clinical relevance spanning comparative animal studies to women's health.

Available in PDF, EPUB and Kindle. Book excerpt: Personnel working in assisted reproductive technology often lack the opportunities for dedicated training in the specialized techniques and technologies required for the procedures. As such, success in the form of live birth rates can range from over 50% to less than 10% per treatment cycle. This comprehensive introductory textbook is an essential resource for trainee embryologists, medical students and nurses. The recent revolutions in biotechnology and molecular biology involved in delivering assisted reproductive services are thoroughly discussed. Basic knowledge such as the development and physiology of both male and female reproductive systems is covered, with practical aspects of IVF including gamete and embryo manipulation, cryopreservation and genetic testing explained in detail. A full description of the optimal structure and management of the IVF laboratory is given, helping ensure procedures are safe and effective. Extensive and highly detailed colour illustrations bring the content to life and aids readers in their understanding.

Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide
