Book Synopsis The Biostimulatory Effect of Bulls on Postpartum Follicular Wave Development in Postpartum, Anestrous, Suckled Beef Cows by : Jarrod Robert Charles Wilkinson
Download or read book The Biostimulatory Effect of Bulls on Postpartum Follicular Wave Development in Postpartum, Anestrous, Suckled Beef Cows written by Jarrod Robert Charles Wilkinson and published by . This book was released on 2009 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this experiment was to determine if bull exposure influences follicular wave dynamics in primiparous, postpartum, anestrous, suckled, beef cows exposed to bulls. In Experiment 1, cows were exposed (continuously 24 h/d), (EB; n = 5) to bulls or not exposed to bulls (NE; n = 5) throughout the experimental period. In Experiment 2, cows were exposed to bulls for either 12 h, (EB12; n = 15), 6 h, (EB6; n =14) or not exposed to bulls (NE; n = 10) from the start to the end of the experimental period. In Experiments 1 and 2, cows were 67 d " 3.8 (mean " SE) and 51.5 " 2.3 d postpartum at the start of the experiment. Follicular characteristics of each cow were examined by transrectal ultrasonography. In Experiment 1, interwave interval for wave 3 was shorter in EB than NE cows. Maximum dominant follicle (MDF) diameter tended to be greater during wave 2 for EB than NE cows, while wave 3 was greater for EB than NE cows. However, MDF diameter for wave 6 was greater for NE than EB cows. In Experiment 2, EB12 cows had fewer follicular waves to the resumption of luteal activity (RLA) than NE cows, while the number of waves to RLA for EB6 cows did not differ from that of EB12 or NE cows. Normalizing follicular waves to the time of RLA for cows within the EB12 and EB6 indicated that those cows at RLA had larger MDF diameters for the wave that produced the ovulatory follicle than cows that did not RLA. These data show the effects of bull exposure in altering follicular growth and developmental patterns, shortening the inter-wave interval and increasing the MDF diameter. Though the mechanism through which bull exposure alters postpartum follicular development is not entirely understood, these data provide new understanding.
Book Synopsis Neurobiology of Chemical Communication by : Carla Mucignat-Caretta
Download or read book Neurobiology of Chemical Communication written by Carla Mucignat-Caretta and published by CRC Press. This book was released on 2014-02-14 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the results achieved so far by application of various biological systems (including genomics, transcriptomics, proteomics, and metabolomics) involved in the pathomechanisms and early diagnosis of periparturient diseases as specific biomarkers of disease in cattle. These emerging technologies help to extensively enhance our understanding of the etiology and pathogenesis of periparturient diseases of transition dairy cows. The book includes a chapter dedicated to ‘omics’ sciences and one that discusses the myths established in animal and veterinary sciences in recent decades and emerging, new paradigms. The diseases discussed include metritis, mastitis, laminitis, ketosis, rumen acidosis, periparturient immunosuppression, gastrointestinal microbiota and their involvement in disease, infertility, fatty liver, milk fever, and retained placenta. This book is intended for academics, veterinarians, animal nutritionists, researchers, and graduate students working in the field of ‘omics sciences’ with a special interest in dairy cattle health.

Book Synopsis Pheromones and Reproduction in Mammals by : John Vandenbergh
Download or read book Pheromones and Reproduction in Mammals written by John Vandenbergh and published by Elsevier. This book was released on 2012-12-02 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pheromones and Reproduction in Mammals reviews current research findings on the role of pheromones in mammalian reproduction. Drawing on both quantitative laboratory studies and selected observational field studies, the book explores how animals actively deploy scent to facilitate sexual interactions and the functions of those scent signals during these interactions. Organized into two sections encompassing nine chapters, this volume begins with an overview of chemical signals and how they influence reproductive behavior in a variety of mammalian species. It then discusses the nature of chemical signals and olfactory perception; the role of chemical communication in mother-young interactions and in the reproduction of primates; how pheromones regulate puberty and the ovarian cycle; and pregnancy blocking by pheromones. The reader is also introduced to hormonal responses to primer pheromones; sensory physiology of pheromone communication; and the role of pheromones in the reproduction of domestic animals such as cattle, swine, sheep, and goats. Biologists and students of biology will find this book extremely informative.
