For The Dying Calves

Poetically written and originally given as lectures, this is a moving essay collection from Durs Grünbein. In his four Lord Weidenfeld Lectures held in Oxford in 2019, German poet Durs Grünbein dealt with a topic that has occupied his mind ever since he began to perceive his own position within the past of his nation, his linguistic community, and his family: How is it possible that history can determine the individual poetic imagination and segregate it into private niches? Shouldn't poetry look at the world with its own sovereign eyes instead? In the form of a collage or "photosynthesis," in image and text, Grünbein lets the fundamental opposition between poetic license and almost overwhelming bondage to history appear in an exemplary way. From the seeming trifle of a stamp with the portrait of Adolf Hitler, he moves through the phenomenon of the "Führer's streets" and into the inferno of aerial warfare. In the end, Grünbein argues that we are faced with the powerlessness of writing and the realization, valid to this day, that comes from confronting history. As he muses, "There is something beyond literature that questions all writing."

Toxic plants and other natural toxicants have a variety of roles in the fields of human health, medical research and the production of safe food and also represent an economic problem in terms of animal health and crop production. Estimates of economic impact on livestock have ranged in the millions of dollars in countries such as Australia and the United States. This book brings together applied and fundamental research from botanists, chemists, biochemists, agricultural scientists, veterinarians and physicians and advice from regulatory bodies. It consists of more than 100 edited papers from the Fifth International Symposium on Poisonous Plants, held in Texas in May 1997. All aspects of poisonous plants, mycotoxicoses and herbal intoxications are covered. Their adverse effects are described, such as fatalities, reduced or failed reproduction, fetotoxicity, spontaneous abortions, deformities, reduced productivity and organ-specific toxicity. Methods of detection, isolation and identification of the chemical compounds responsible are included. The biochemistry of the plant-associated toxins and elucidation of their mechanism of action is investigated, including the protocols for management or eradication, immunization programs, behaviour modification, withholding periods for metabolic detoxification, regulatory advice concerning human usage of natural products and advice concerning toxin-residue in agricultural produce. The development of non-toxic strains of plants for use as fodder is also discussed. This book is essential reading for toxicologists concerned with animal and human health, food industry regulators and plant scientists.

Factors Affecting Calf Crop summarizes the latest information available from leading cattle physiologists and geneticists regarding factors known to influence the production of live calves at weaning. You get practical information on management techniques for improving reproduction efficiency in the herd. You'll also learn about the functioning of the reproductive system and how this may affect reproductive processes in the cow herd. Managers will benefit from a clearer understanding of the factors known to limit efficient reproduction, while veterinarians and other professionals who advise cattlemen will appreciate the substantial reference material and color photographs for defining cow condition scores. Color photographs are also used to illustrate the discussions of testicular thermographies and their applications. Other chapters in the book cover developments in improving reproductive performance of the replacement heifer, the brood cow, and the bull. Topics on reproduction include physiology/endocrinology, the use of growth promotants, genetics and physiological and economic considerations in selecting the age to breed heifers, heritability of fertility, length of the breeding season, prepartum and postpartum nutrition, nursing by the calf, cloning of embryos, and much more.

This publication contains the proceedings of a seminar held in Germany (Fed. Rep.) on May 4 -6, 1977, under the auspices of the Commission of the European Communities, as part of the EEC programme of co ordination of research on beef production. The programme was drawn up by a combined scientific working group on Genetics and Selection and on Nutrition and Management on behalf of the Beef Production Committee. The working group consisted of Professor Dr. Neimann S~rensen (Denmark, Chairman), Dr. Brolund Larsen (Denmark), Mr. Boccard (France), Dr. H. de Boer (Netherlands), Priv.-Doz. Dr. B. Hoffmann (Germany, Fed. Rep.), Professor Dr. H.J. Langholz (Germany, Fed. Rep.), Dr. J.W.B. King (UK), Mr. R. Jarrige (France), Mr. B. Vissac (France), Professor Dr. A. Romita (Italy), Professor Dr. E.P. Cunningham (Ireland), Mr. P. L'Hermite (CEC) and Dr. J.C. Tayler (Scientific Adviser to CEC). The subject chosen for this seminar was drawn from the list of priorities in research objectives drawn up in 1973 by members of a committee (now the Standing Committee on Agricultural Research, (~PRA). One of the functions of this series of seminars was to summarise and update the information available on the selected subjects and to discuss future needs for research, so as to assist the Commission in evaluating the probable impact of research on agri cultural production within the Community.
