ARTIFICIAL INSEMINATION IN FARM ANIMALS - Original PDF
نویسندگان: خلاصه: Artificial insemination is used instead of natural mating for reproduction purposes and its chief priority 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. This book contains under one cover 16 chapters of concise, up-to-date information on artificial insemination in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs. 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 are described. 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.

Veterinary Immunology 10E - Original PDF
نویسندگان: خلاصه: This textbook was first published in 1977, at a time when veterinary immunology was relatively new and poorly understood. Nevertheless, it was recognized, even then, that immunology held the key to many of the significant issues in veterinary medicine. The importance of immunology has not declined since then, except among those tasked with establishing college curricula. The decline in basic science instruction at colleges of veterinary medicine in favor of more clinical training has resulted in graduating a generation of veterinarians whose knowledge of immunology is minimal. Yet immunology continues to be a key science. It is central to our understanding of major veterinary issues such as vaccination, cancer, infectious diseases, and allergies. It has been tempting to dilute the contents of this text and its associated website to conform to current curricular trends. I have resisted this. Because the amount of knowledge of immunology required to obtain a veterinary degree has been progressively reduced, the need to document the science in depth has correspondingly increased. This book therefore continues to grow as the result of opening up new, exciting areas of the science. Veterinarians need to know much of this if they are to practice cutting-edge science in the 21st century. Read it, study it, and enjoy its wonderful complexity. Over the many years that this textbook has been published we have seen many changes in the science of immunology. In most cases, these changes have been gradual in nature as investigators add detail to existing knowledge. Occasionally, however, major leaps are made that effectively revolutionize the discipline—socalled paradigm shifts. For example, in the late 1990s, the concept of innate immunity was accepted. Inflammation and other processes were finally recognized as being essential components of the immune system and the dual innate and adaptive immune systems were shown to complement each other. It is interesting to note that this was not a new discovery but a new way of looking at well recognized processes. This new edition also reflects revolutionary changes in the way we think of immunology. Like the concept of innate immunity, these changes are not a result of a previously unknown process but a belated recognition of something known about since the dawn of microbiology, the body's normal microbiota. New methodologies and intensive studies have revealed that many body processes, especially immunity, are regulated by the diverse microbiota that colonizes all body surfaces. Much of immunology has had to be reassessed in the light of this new knowledge. Both innate and adaptive immunity are regulated by those organisms, especially bacteria, that live in the intestine and respiratory tract and on the skin. Many previously unexplained phenomena have now been shown to depend on the normal microbiota. As a result of this new information, the reader will encounter the microbiota at every turn in this book, plus a completely new chapter on the subject. The second new chapter deals with allergic diseases. For many years, these were readily explained by the production of IgE against allergens. The most recent information, however, has demonstrated that allergies are much more complex than this. For example, atopic dermatitis, one of the most common conditions seen by small animal veterinarians, is likely a syndrome with multiple complex causative factors. As a result, allergic and inflammatory diseases deserve a new chapter. These additions cannot, however, hide the fact that the rest of immunology also continues to move forward. Thus the mechanisms by which the body rejects gastrointestinal helminths has been clarified with the discovery of the importance of tuft cells and interleukin-33. Associated with this has been the recognition of the complex nature of innate lymphoid cells and their subpopulations. Some of these advances can be considered routine, such as the identification of new cell surface molecules and many new cytokines. New disease syndromes such as swine SCID, bovine neonatal pancytopenia, and immune-mediated keratoconjunctivitis are now described, and the pathogenesis of others such as atopic dermatitis, type I diabetes mellitus, equine laminitis, and systemic lupus are shown to be more complex than previously believed. New advances in therapy are covered, including the introduction of immune checkpoint therapy in cancer and the use of monoclonal antibody therapy and intravenous immunoglobulin therapy for immune-mediated diseases. The exciting new developments in the use of nanoparticles in vaccines and as adjuvants are now described. The significant roles of vitamins A and D as well as the aryl hydrocarbon receptor in immunity are also recognized. Advances in basic science that are now discussed include new findings on the structure and genetics of bovine antibodies, epigenetics, RNA interference, microRNA, macrophage polarization, and type 1 and type 2 immune responses. I make no apologies for the size and complexity of this text. Immunology is a complex subject that has a direct bearing on many of the most important areas of veterinary medicine. Students, as well as graduate veterinarians, ignore it at their peril. Finally, readers are strongly encouraged to visit the Evolve website for this text. The site is also constantly evolving and improving. In it you will be able to find a collection of more than 450 multiple-choice questions (with the answers!) keyed to each chapter; a set of flashcards also linked to chapters; all the text figures available as PowerPoint slides; and a collection of animations kindly provided by Dr. Abul Abbas, as well as brand new animations created for this textbook, designed to clarify some complex processes and pathways where still figures are inadequate. All the chapter references are keyed to PubMed. There are also new hand-outs that students can print off and use as a reference, should you wish. It is my hope that these assets will help you remain current in this rapidly expanding and exciting field.

Direct Microscopic Somatic Cell Count - Original PDF
نویسندگان: خلاصه: The direct microscopic somatic cell count (DMSCC) is microscopic count of the actual number of somatic cells in milk. A somatic cell is any biological cell forming the body of an organism. In dairy industry, the somatic cell count (SCC) is an indicator of the safety and quality of milk. Mastitis is an inflammation of the udder typically associated with microbial infection. The number of somatic cells increases in response to presence of pathogenic bacteria like Staphylococcus aureus, a cause of mastitis. Somatic cells (SC) are cells from the cow (predominantly white blood cells, otherwise known as leukocytes) that are normally present in milk. During most mastitis infections, the number of leukocytes present in the udder increases to help the cow, goat, ewe, camel, buffalo etc. to fight the infection. The SCC is quantified as cells per milliliter. General agreement rests on a reference range of less than 100,000 SC in ml for uninfected cows and greater than 250,000 SC in ml for cows infected with significant pathogen levels. There are several indirect and direct laboratory methods used for determination of somatic cells count in milk. Routine instrumental laboratory methods like flow cytometry have to be regularly calibrated using reference materials with a known concentration of somatic cells. The concentration of somatic cell count can be determined by reference microscopic method. The first microscopic procedure for examination of milk films was described in 1910 by Prescott and Breed. Staining of somatic cells was later modified by Newman, Lampert, Levowitz, Weber and other researchers. This microscopic method was processed into a normative form by the International Dairy Federation and later by International Standard Organisation. There are several possibilities to stain somatic cells. Somatic cells can be stained by dipping the dried smear on the slide in the modified Newman-Lampert methylene blue stain solution (cow’s milk and ewe’s milk) or methyl green-pyronin Y stain solution (goat’s milk) or by mixing the milk in reagent tube with ethidium bromide stain solution (milk from all species). Subsequently, the microscopic slide with fixed smear and stained cells is examined using a microscope or epifluorescence microscope with immersion oil objective at magnification 500× to 1000×. Somatic cells are counted in several microscopic fields. Consequently, the somatic cells count is calculated using one of several mathematical formulas listed in international standard. The direct microscopic somatic cell count method is suitable for precise laboratory analysis of somatic cell in raw milk. However, this microscopic method has some limitations that may influence the results of analysis. This book contains the theoretical and practical information about this laboratory method.
Microbiology Handbook: Dairy Products - Original PDF
نویسندگان: خلاصه: Milk and dairy products form a central part of the human diet, as they are rich in nutrients. On the other hand, because of their high nutrient value, they favour rapid microbial growth. In some cases, this microbial growth is beneficial, while in others it is undesirable. Dairy products may be contaminated with pathogens or microbial toxins; therefore, the microbiology of these products is of key interest to those in the dairy industry. 'Microbiology Handbook - Dairy Products' provides readers with an easy-to-use reference to microorganisms found in milk and dairy products. The handbook covers: initial microflora; sources of contamination; effects of processing on the survival and growth of microorganisms; spoilage; and hazards identified with the consumption of these products.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
