This book reports the proceedings of a symposium held in Adana, Turkey, from 2 to 6 November 1991, that was organized as part of the series of symposia jointly conceived by the European Association for Animal Production (EAAP) and the International Centre for Advanced Mediterranean Studies (CIHEAM). It is useful to recall that the goal of these symposia is to develop aspects of animal agriculture in the Mediterranean region that are now normally covered by other scientific meetings. The Adana symposium was dedicated to the production and use of hides, skins, wool and hair, which, in the Mediterranean basin, are considered byproducts or at least of secondary economic importance relative to the production of meat and milk. Although merino-type and semi-fine wools were not covered by the symposium, 12 of the 35 main papers presented refer to fibres from sheep and goats. The accent was more on angora goats, for which Turkey is the world cradle, and on cashmere goats. Many papers deal with the strategies of developing these genetic resources outside their countries of origin, where they could provide possibilities of diversifying animal production for high-value products in specialized small flocks, such as in Europe (France and Italy), where both species were imported over the last ten years. Three papers are also dedicated to the development of cashmere goats in Australia. These reports reveal the interest for a better inventory and knowledge of the original germplasm, for angora goats in Turkey and for cashmere goats in China.
The originality of this book probably lies in the actual interest in this field today, despite the quality of the information and the interest of review papers on the physiological basis of wool and hair production, on the nutritional characteristics and feeding recommendations for developing fibre goat flocks or on the objective measurements of wool. This publication attempts to provide information on the whole production chain, from the animal to the final processed commodity. In fact, two subtitles could have been adopted to cover the main sets of reports: the first "from skin to leather" and the second "from wool to carpets and rugs". In this respect, the book presents real interest in providing information from various sources that would be difficult to collect by one person: statistical data on the production and world trade of hides, skins and leather; analysis of the physical properties of sheepskin; factors determining the quality of the raw material (animal diseases and slaughterhouses); case-studies on the characteristics of the leather industry in Turkey and Morocco; environmental issues facing this type of industry; and the possible uses of by-products of the industry in agriculture.
Two chapters are dedicated to special wool used in the carpet industry, including several reports on the relationship between the specific qualities of the local sheep breeds and the characteristics of the handmade carpets in Egypt, Turkey, Algeria, Morocco and Italy (Sardinia). Many reports present the tradition and the various characteristics of carpets in Turkey but, unfortunately, without reproductions of the very significant photographs of the various designs and natural colours of the carpets to illustrate the presentation because of high printing costs.
It was the intention of the symposium organizers to examine to what extent the low productivity of animal material and production systems in the Mediterranean basin could be compensated for by high-value specific and typical products. These reports provide technical information on the relationship between producing the raw material and processing it in order to control the performance of the whole chain. One of the problems discussed but not resolved was to what extent the farmer could benefit from this final high commercial value in order to continue to maintain livestock activities in the difficult and marginal Mediterranean environment.
This book has both the qualities and the weaknesses of the proceedings of a good symposium. It contains original information rarely available, but it lacks a balance between the various subjects of interest because of the varying quality of the reports and papers presented. Overall, it is a perfect reflection of the unique opportunity offered by such a symposium: the exchange of information between animal production specialists and industry representatives, not only from the leather industry but also from the traditional handwoven carpet sector.

L'ouvrage, modeste quant au volume (119 pages), mais ambitieux quant au propos, traite d'écopathologie animale, branche récemment développée de l'épidémiologie animale, dont on peut donner, avec Faye, la définition suivante: «étude des relations complexes entre l'environnement, c'est-à-dire l'ensemble des conditions géoclimatiques et technico-économiques auxquelles sont confrontés les éleveurs et leur cheptel, et les états pathologiques survenant au sein des troupeaux». L'ouvrage est une publication conjointe de l'Institut national de la recherche agronomique (INRA, France) et du Centre de coopération internationale en recherche agronomique pour le développement (CIRAD, France). Il est publié dans la collection «Du labo au terrain».
L'ouvrage, collectif, signé par des spécialistes reconnus de l'épidémiologie tropicale, s'intéresse plus particulièrement aux aspects méthodologiques et aux applications de l'écopathologie animale au milieu tropical. Les auteurs dépassent de fait l'approche classique des programmes nationaux ou internationaux de lutte contre les grandes maladies infectieuses ou parasitaires du bétail sous les tropiques. Ils centrent leur réflexion autour d'un outil né de la nécessité de donner une réponse opératoire à la lutte contre des troubles sanitaires dus à un ensemble complexe de facteurs liés, alors même que la démarche pastorienne, linéaire, monofactorielle semble atteindre ses limites dans le contexte pluricausal des pathologies observées dans les systèmes d'élevage tropicaux, extensifs notamment. Débouchant sur l'identification des facteurs de risque à partir desquels l'éleveur et son encadrement technique peuvent agir directement, l'écopathologie constitue dès lors un outil de développement efficace dans l'action sanitaire, même si ses limites restent encore à préciser.
Après avoir traité de l'écopathologie comme d'une méthode d'approche des problèmes de santé animale, les auteurs proposent quelques réponses méthodologiques adaptées aux contraintes spécifiques des pays en développement. Ils illustrent notamment leur propos par trois études de cas, au Brésil, au Tchad et au Sénégal. Ils relèvent enfin avec pertinence le fait que l'écopathologie animale sous les tropiques - que l'expérience future et les résultats à venir devront enrichir - est appelée à dépasser le cadre des grandes maladies à caractère épizootique pour s'élargir aux troubles enzootiques à étiologie multifactorielle et prendre en compte les pratiques d'élevage, les conditions d'alimentation du cheptel, les données socioéconomiques, entre autres facteurs. Conçu pour un public de professionnels: acteurs du développement, chercheurs, formateurs, l'ouvrage, à la fois outil de reflexion et guide pour l'action, peut être commandé aux Editions INRA, Route de St-Cyr, 78026 Versailles Cedex, France, ou au Service de documentation du CIRAD-EMVT, 10, rue Pierre-Curie, 94704 Maisons-Alfort Cedex, France. A tous ceux qui sont partie prenante dans la maîtrise des pathologies animales sous les tropiques et leur incidence sur les productions animales, on ne saurait trop recommander la lecture de cet ouvrage.

This book takes an interesting - even exciting - but classical approach to the presentation of the state of the art and census of national and regional animal genetic resources in North America. It can be a reference for the reporting of other similar cases, reviewing available information and linking local policies to the conservation of genetic diversity in livestock at the moment that census data become available.
The book is produced by the American Livestock Breeds Conservancy (ALBC), a non-profit organization working to protect genetic diversity in North American livestock through the conservation of nearly 100 breeds of donkeys, cattle, goats, horses, sheep, pigs, and poultry. Originally founded as the American Minor Breeds Conservancy (AMBC) in 1977 in New England, the organization is supported by gifts from individuals, grants from foundations and corporations, and contracts.
Agricultural historians, while seeking authentic period livestock for interpretive programmes at Old Sturbridge Village and other historic sites in the United States, discovered that many heritage breeds were nearly extinct. The historians joined with farmers and animal scientists to form AMBC, and set its mission as the conservation of endangered livestock breeds. The organization moved to Pittsboro, North Carolina, in 1985. The name was changed to the American Livestock Breeds Conservancy in 1993 to reflect the increasingly serious threat to all livestock breeds, with a consequential widening of the organization's sphere of activities.
ALBC directs many conservation and research programmes. A periodic census of livestock breeds, which includes the monitoring of bloodlines within many of the rarer breeds, provides the knowledge base for developing these programmes. Conservation projects include breed identification using a gene bank, blood typing and DNA fingerprinting, rescues of threatened populations and the development of genetic-recovery breeding programmes. Technical support for conservation breeding, registry operation and livestock use is provided to breeders, breed associations and agricultural organizations. Outreach programmes educate the public and policy-makers on the importance of genetic diversity in livestock.
The book is divided into three main sections. The first section can be considered a compact manual on livestock genetic resources, their diversity and conservation. The first chapter gives a short historical overview of the livestock sector from the first stages of domestication to the specifics of North American populations. Then follow four chapters, written in a rather academic style, on the importance of genetic diversity, the principles of genetic erosion with special reference to North America and the influence this can have in an agricultural context. Finally, a chapter describes the reasons for the conservation of genetic diversity in farm animals: food security, economic opportunities, environmental monitoring, stewardship of scientific knowledge and aspects relating to culture, history and ethics.
The second section covers census results, breed by breed, from 1990 to 1992 with some reference to previous information, particularly data from the first census that ALBC undertook in 1985. The information (from the United States and Canada) includes registration figures, estimates of global populations, number of breeders and lists of all officially recognized associations, as well as cumulative registrations and summary information on breed registration policies when information was available, which evidently was not the case for all breeds. The information is presented by species : donkeys, cattle, goats, horses, sheep and pigs. A useful short census summary completes this section.
The third section looks at conservation and selection policies, with summary descriptions of breed status, breed characterization and breed potential and actual use. The importance of research in livestock conservation and the role of the public and private sectors in conservation programmes is discussed, as well as the need for corporate support. Some information is given on international cooperation.
Two appendixes give further value to the book. The first describes three case-studies: An economic history of the United States livestock industry; Extinct horse breeds; and Extinct goat breeds. The second comprises the North American feral livestock census. A short glossary completes the publication.
Attractively produced, this book can serve as a reference publication for all those involved or interested in the conservation of farm-animal genetic diversity, and also as a good textbook for university students.

This book contains the proceedings of a workshop held in Nantes, France, in October 1992 around the central theme of humans, the domesticated animal and the environment from the Middle Ages to the eighteenth century. This very interesting meeting was jointly organized by the History Department of the University of Nantes (Brittany) and the Nantes National School of Veterinary Science.
The book was collectively produced by a number of scientists and academics who share an interest in the history and development of regional identities and who were present at the very start of the development of CRHMA at the University of Nantes.
The study of people and domesticated animals in relation to the environment during the period from the twelfth to the eighteenth century in Europe brings to light a mass of existing relationships and interactions that deeply influenced the socio-economic history of the Western world as a whole. Some relationships that developed throw a definite light on the parallel and interwoven evolution of three groups of research activities: history, veterinary and animal science, and the sciences of the environment. Here the role of archaeozoology can be retained in the study of breeds and types of domesticated animals that were developed in the past and those existing today, the historical role of major domesticated species in the extension of the agricultural zones in Europe and the evolution of the various ecosystems at specific periods in the history of Europe.
The introduction places this workshop within the borders of Europe and the Mediterranean: from Byzantium and the Orthodox world to Muslim Spain, and from the Viking north to catholic Hungary. This is followed by a brilliant descriptive paper on animal domestication and the relationship between humans and farm animals.
Comprising 28 papers, the book is divided into four main sections: social status of domesticated animals; the management of domesticated animals; protection and animal health; and domesticated animals and their environment. The papers are all, without exception, of great interest as they touch on fields long underestimated by the animal scientists practising at the end of the twentieth century. Each paper is completed by an up-to-date bibliography.
The authors are eminent French scientists, academics and professionals in their fields of interest and study. The importance of this workshop was that it brought together experts of disciplines as different as sociology, the history of the rural world, veterinary science, archaeozoology, ethology and animal agriculture, to mention only a few. The organizers of the workshop truly succeeded in convening an interesting group of people from varying fields of expertise and professional involvement.
This publication is an original contribution, rich in material as wide ranging as economic anthropology and social history. This diversity of information underlines the critical role played by the farm-animal sector in history and explains its dynamic evolutionary influence. The book includes information on very interesting studies awaiting publication on the crossroads of history, animal agricultural and veterinary science, ecology, ethology and literature.

The first of these two new booklets published in 1994 by the National Resources Institute (NRI) in the Use of Trees by Livestock series deals with the genus Ficus (Moraceae) and the second with the genus Callimdra (Leguminosae, Mimosoideae). Titles in the series to date include: Prosopis, No. 1; Acacia, No. 2; Gliricidia, No. 3; Anti-nutritive factors, No. 4; Quercus, No. 5; and Cassia, No. 6. The aim of this series is to bring together published information on selected genera of trees that have the potential of increasing the supply of fodder for ruminants. The format is reduced (about 20 pages) and attractive. Each booklet describes one genus and its distribution, then summarizes information on the fodder characteristics, nutritive value, antinutritive factors, management and alternative uses. A short list of references for further reading can be found at the end of each publication. All who are convinced of the importance of trees and shrubs in the feeding of animals in the tropics and subtropics and those engaged in research and development activities should have these useful booklets on hand.

This book is one of an agriculture series highly recommended for practical farm management. It will ser ve as an excellent guide for farmers, herders, advisers, farm managers and students of animal husbandry and agriculture, leading to better comprehension of farm management. Unlike other farm management textbooks, it provides separate explanations for agriculture and livestock farm management with suitable examples.
In five parts, the role functions of management, planning, control, implementation-acquiring and managing resources are dealt with, as well as additional management topics such as income taxes, risk and uncertainty. There is also a classified index for quick reference.
The author pro vides elaborate discussions on implementation-acquiring and managing resources in the scientific methods of calculation. Even though this part provides crisp accounts and clear sketches of various methods of acquiring resources, it might have been substantiated with newer and easier methods of calculating internal rates of return and of analysing investments, with some emphasis on dynamic programming for machinery and livestock replacement.
Readers will be impressed by the latest information provided on the use of computers in farm management, a highly useful chapter missing in other textbooks that is suitable for all those interested in farm management.

This book contains a wealth of practical information for those involved with the management and breeding of horses at all levels. The necessary knowledge of reproductive anatomy and equine physiology and state-of-the-art information on embryo transfer, artificial insemination, hormonal manipulation and their applicability to the various systems existing on stud farms are presented and discussed in depth in a practical and efficient way. The author successfully argues that, whatever the developments and achievements in the adoption of new and avant-garde technologies might have been in the last century, these were only made possible through the direct involvement of stud breeders and horse-farm managers.
The book is divided into two sections. The first concerns reproductive anatomy and physiology, with equal attention given to stallions and mares. Two informative chapters deal with pregnancy and parturition, including problems relating to early and late pregnancy as well as foaling abnormalities. Two very original chapters concern issues of lactation and milk secretion: mammogenesis, lactation curves and milk quality, milk synthesis, milk ejection, lactogenesis and galactopoeisis.
In the second section, the author successfully describes and presents in easily comprehensible language matters relating to breeding and selection with several well-documented, practical chapters on animal management: mating practices, the pregnant mare, parturition, the lactating mare and foal, young stock and the stallion. In the two last chapters many practical tips on artificial insemination and reproduction biotechnology are given.
The book is richly illustrated by numerous attractive and explanatory photographs and very detailed drawings. Each chapter is enriched by an up-to-date bibliography. It is not only of special interest to university lecturers, scientists and students, but also to veterinary practitioners, breeders, stud-farm managers and those horse owners who are interested in updating their scientific knowledge. It is destined to take its rightful place among the few books on horses published this past decade that have been recognized as authoritative and truly informative.
Equine reproductive physiology, breeding and stud management is available from some bookshops or direct from Farming Press Books and Videos, Wharfedale Road, Ipswich IP14LG, United Kingdom. If ordering direct, please add £.2.50 for postage and packing.

Cet ouvrage est un numéro spécial d'Ethnozootechnie consacré à la 4e Journée d'étude de la Société d'ethnozootechnie, tenue le 2 décembre 1993 à l'INAPG, sous la direction de Jacques Bougler et Etienne Verrier. Cette réunion a fait le point sur les travaux réalisés, les difficultés rencontrées et/ou surmontées et les lacunes des politiques en matière de conservation du patrimoine génétique animal, avec référence spéciale à la France.
L'ouvrage souligne le fait qu'au début des années 80 la sauvegarde des populations autochtones encore existantes était la préoccupation dominante, puis a succédé la phase de mise en œuvre de projets de conservation. Aujourd'hui, il faut raisonner la mise en valeur de certains de ces projets.
En introduction, l'ouvrage fait la synthèse de deux importants colloques qui se sont tenus en France. Le premier (Rambouillet, 24 septembre 1992) est une contribution sur les problèmes des races domestiques en péril, les initiatives de conservation et leur relative absence de coordination. Le second (Montpellier, 28-30 septembre 1993) a discuté les méthodologies d'étude et de gestion des ressources génétiques, tant animales que végétales.
Les comptes rendus du colloque comprennent sept parties - avec des études de cas spécifiques -, à savoir:
· la nécessité d'une valorisation des populations conservées;· le rôle économique de la conservation des races en péril;
· les produits d'appellation d'origine contrôlée (AOC) comme élément de soutien et de mise en valeur des races régionales;
· stratégie de recherche à long terme
· le rôle des éleveurs;
· la PAC et l'aide aux races de petits effectifs;
· les lacunes des politiques actuelles. En conclusion, ce numéro d'Ethnozootechnie contient un excellent document de J.G. Hall sur la biodiversité du bétail de ferme, traduit de l'anglais.

In many developing regions, particularly in rural abattoirs, meat inspectors often lack the necessary information and guidelines to properly assess the sanitary status of carcasses, meat and organs from slaughtered animals. In response, FAO has prepared concise guidelines on the subject, aided by 200 colour illustrations demonstrating the pathological lesions that may occur in bovines, small ruminants, pigs, game, poultry and rabbits.
Manual on meat inspection for developing countries has been prepared by an experienced meat inspection specialist as the main author in cooperation with meat inspection experts from the four regions of Asia and the Pacific, Africa, Latin America and the Near East. The book is intended to guide meat inspectors, particularly those in the four regions mentioned, in their daily work in urban and rural abattoirs. Recommendations for the daily routine work of judging diseased carcas ses, or parts thereof, were influenced by the need to salvage as much meat as possible for human consumption. Veterinarians engaged in meat inspection will also benefit, especially with regard to their supervisory roles in meat hygiene. The book will also serve as a training manual for students of meat inspection, a field in which FAO periodically organizes theoretical and practical training courses. G.H.

Desde hace ya algunos años la FAO viene desarrollando un programa orientado al establecimiento, preferentemente en áreas rurales, de pequeños mataderos modulares con el propósito de que puedan servir de modelo a imitar en el resto del país o de la región en que se han ubicado.
El propósito de este Manual es presentar una serie de normativas para el adecuado funcionamiento del pequeño matadero modular. Se ha pretendido además que el Manual pueda servir también como material docente en los cursos de capacitación que se imparten dentro del mencionado programa de la FAO.
El Manual está dividido en 10 capítulos, Tras el primero, en el que se describen las características del matadero modular y del programa de la FAO para su establecimiento, los tres capítulos siguientes están dedicados a la descripción de los procesos de sacrificio y faenado del ganado bovino, porcino, y ovino y caprino. En al capítulo quinto se abordan los temas referentes a la evaluación de las canales, mientras que en el sexto y séptimo se hace lo propio con los relativos a despiece de canales y fabricación de productos cárnicos, respectivamente. La utilización de subproductos es el tema al que se dedica el capítulo octavo, estando dedicados los dos últimos a la evacuación de aguas residuales y a la limpieza e higiene de las instalaciones.
Dado que el objetivo principal de este Manual está relacionado con el funcionamiento del matadero modular, en cada uno de los capítulos mencionados se describen con detalle las correspondientes operaciones a realizar en él. Sin embargo desde un punto de vista pedagógico el Manual adolece de una falta de homogeneidad en el desarrollo y nivel de los diferentes capítulos. Ello es debido a que existen otros manuales de la FAO donde se abordan los mismos temas y se ha pretendido evitar repeticiones innecesarias. Así, en algunos capítulos, se hace referencia fundamentalmente al funcionamiento del matadero modular, por lo que durante la enseñanza se deberá recurrir a otros manuales de la FAO. Otros capítulos, en los que los temas que se desarrollan no han sido objeto de publicaciones recientes de la FAO, se han dividido en dos partes. En la primera se describen los procesos en mataderos de medio y gran tamaño y en la segunda los que se refieren al pequeño matadero modular.

The health of poultry, one of the Longman Veterinary Health Series, is a unique book describing the general concepts of poultry health with an emphasis on creating the right conditions and environment to minimize the occurrence of disease. By demonstrating the interrelationships between husbandry, medicine and nutrition, the author shows how to prevent disease and maximize the genetic potential made possible with modern poultry breeds.
The main poultry species - chicken, including breeder and broiler, turkey and duck - are dealt with in separate chapters, each explaining the principle of disease control with an emphasis on preventive medicine. All aspects of care are drawn together to provide guidance on devising a rigorous health regime that is controlled by proper management. Chapters on hatchery, nutrition, environment and housing examine topics such as planning, ventilation, hygiene, quality control and medication. A discussion of the important role of genetics in flock health encompasses such issues as genetic resistance to disease, vertically transmitted diseases and strategies for disease control.
The book provides a complete view of the health and welfare of poultry. As such, it will be a highly practical addition to the bookshelves of poultry farmers, specialists and veterinarians. Agriculture and veterinary students embarked on B.Sc. and diploma courses in poultry will find the coverage informative and the style lucid and accessible.
