The goatkeeper's veterinary book

Peter Dunn. 3rd ed., 1994. Farming Press Books & Videos, Ipswich, UK. Price: £13.95 (hardback).

Mr Dunn is a veterinarian with wide experience in dealing with problems of raising goats in the United Kingdom and in France. As might be expected, his training and experience bring both sound practical knowledge as well as an emphasis on goat diseases. The book primarily deals with goat husbandry in temperate climates. The text is somewhat technical, which limits its use to the experienced goat keeper. The author is well aware of this, however, as illustrated on page 8 in the section "When to seek help from the vet". He cautions that general rules are not easily stated and that when to seek help depends partly on the goat keeper's experience. He advises goat keepers to look up relevant sections in the book, but recognizes that this presupposes that the goat keeper knows what the problems are. And herein lies the weakness of some practical books written by veterinarians for livestock raisers: livestock raisers require experience and familiarity with the veterinary vocabulary and disease symptoms in order to make a diagnosis.

From the practicing veterinarian or livestock extensionist's point of view, this is an ideal book to distribute to goat keepers, as a point of departure for their continuing education, and to their professional advisers. Many questions will be asked by goat keepers after they have read the book and observed their herds. These questions could form the basis of the livestock raiser's continuing education.

The book is quite practical, and the author rightly advocates that owners should vaccinate their own animals, assist with birthing and check for mastitis and other health problems. A balanced discussion of what-are perceived as the most important problems encountered when raising goats in temperate climates is provided. The important role of good nutrition is emphasized, as well as the detrimental effects of internal and external parasites. Infectious diseases are covered in-depth, as well as non-infectious diseases, such as acetonaemia and some plant poisonings. A chapter on raising kids is also included, which is very useful for the goat keeper.

In short, the book includes a large amount of good animal husbandry advice although on a very technical level. And numerous informative black-and-white and colour photographs and illustrations add much to this publication.

A new section (Chapter 8) has been added in this third edition on some health aspects of fibre goats, including nutrition, abortion, reproduction and fertility, and parasite problems with angora and cashmere goats. Brief references to disease and production problems in other developed countries as well as in developing countries are sprinkled throughout the book. Also new in this edition is an appendix of information from a goat veterinary society health survey taken over the course of 1984 and involving approximately 1 000 goats in 69 herds in the United Kingdom. In this survey, problems of the digestive tract were most frequently encountered, followed by skin problems and, third, reproductive problems. The survey also suggested that Nubian goats were at a higher risk for many of these diseases.

This book is recommended reading and reference for sophisticated goat keepers to be used in cooperation with their veterinary and extension agents.

Zootechnie des régions chaudes: les systèmes d'élevage

P. Lhoste, V. Dollé, J. Rousseau et D. Soltner. 1993. La Documentation Française, 29-31 quai Voltaire, 75344 Paris Cedex 07, France. 288 pages. ISBN 2-11-087337-3 11. Prix: 180FF

Depuis sa création, l'Institut français pour l'élevage et la médecine vétérinaire dans les pays tropicaux (IEMVT) porte une attention particulière à la formation des experts et techniciens agricoles en milieux tropicaux et subtropicaux, particulièrement en Afrique francophone. Ce livre est le résultat de six années d'activité dans le cadre d'un projet démarré en 1987. Comme le soulignent les auteurs eux-mêmes, ce n'est ni une publication scientifique, ni un livre de référence couvrant tous les aspects de l'élevage sous les tropiques, mais plutôt un manuel basé sur la vaste expérience de formation et de développement de l'Institut, vu sous l'angle des systèmes de production. Le livre tente, avec un certain succès, de poser le problème du secteur élevage d'une région à travers une approche globale (l'environnement physique et social, les ressources génétiques et nutritionnelles et les éleveurs).

Cela est une tentative sérieuse de mettre en lumière la grande diversité des systèmes et des conditions d'élevage en Afrique tropicale et subtropicale, en soulignant les différences qui existent entre ces régions et les zones tempérées de la planète. Alors que les régions tropicales et subsahariennes sont très bien couvertes, beaucoup plus aurait pu être dit sur le bassin méditerranéen subtropical sec.

Cet ouvrage richement illustré sera reconnu comme une des rares publications de ces dernières années qui fasse autorité comme manuel pratique d'élevage dans le monde en développement. II associe des informations de base avec bon sens et une vaste expérience des pratiques culturales. De nombreux scientifiques et techniciens semblent avoir participé conjointement aux auteurs à la préparation de ce livre. Cela a l'avantage indiscutable de réunir un savoir précis et plusieurs décennies d'expérience en pratique d'élevage tropical et de techniques d'élevage expérimentées avec succès.

Le livre est divisé en huit sections. La première présente un historique rapide de l'élevage dans le monde, tandis que la seconde décrit les nombreux facteurs traditionnels qui influencent la production, en faisant particulièrement référence aux sociétés paysannes. La troisième section s'intéresse à l'approche de l'étude des systèmes de production, à partir d'une étude réalisée en basse Casamance au Sénégal. Le quatrième chapitre discute les divers facteurs qui influencent le secteur de l'élevage et introduit l'approche par enquêtes, tandis que le cinquième donne de nombreux exemples de systèmes de production en Afrique et dans d'autres régions tropicales, comme Haïti, le Mexique ou la Chine. Les trois derniers chapitres font le lien entre théorie et pratique: techniques pratiques de sélection et de reproduction, considérations de base sur le plan de la santé animale, et, enfin, la nutrition, notamment le rôle capital de l'eau et la gestion des pâturages et des ressources fourragères.

C'est un ouvrage fascinant, qui mériterait d'être traduit en anglais et en espagnol. Il est richement illustré de photographies en noir et blanc, de dessins et de tableaux. Avec une présentation plus structurée du texte, une bibliographie plus complète et l'introduction des systèmes d'élevage méditerranéens, il deviendrait l'ouvrage de référence des étudiants, des techniciens de vulgarisation, des zootechniciens et des vétérinaires du secteur de l'élevage en zones tropicales et subtropicales.

Production alimentaire mondiale et environnement: notre avenir en jeu.

A. Rérat. 1994. Lavoisier Tec & Doc, 11 rue Lavoisier, 75384 Paris Cedex 08, France. 101 pages. ISBN 2-85206-985-7. Prix: 145 FF.

Ce livre stimulant est une analyse, courte mais profonde et juste, de l'état actuel de la première préoccupation des hommes, leur alimentation aujourd'hui, au point de rencontre des problèmes posés à la fois par leurs activités et par les besoins des sociétés dans lesquelles ils vivent. L'auteur, zootechnicien et administrateur renommé de la recherche, résume les faits et fournit de nombreuses références.

C'est un livre que l'on ouvre sans beaucoup d'intérêt et que l'on lit ensuite d'un trait jusqu'à la dernière page. C'est un aliment pour l'esprit: il donne au lecteur la possibilité de réflections sérieuses tout en corrigeant ou actualisant certaines idées préconçues.

La présentation des deux principaux chapitres du livre suit l'ordre logique choisi par l'auteur qui cherche à ouvrir un débat et à contraindre le lecteur à dépasser son horizon familier et ses pensées quotidiennes: d'un côté, il y a le futur de la production et de la consommation des aliments et les conséquences pour l'environnement au sens large, et de l'autre, une analyse originale de l'influence de l'environnement sur la nutrition et la chaîne alimentaire. Ce problème mondial majeur est abordé du point de vue du scientifique européen, soulignant que nos besoins alimentaires ne peuvent être satisfaits que par une nutrition équilibrée associant une quantité suffisante à une indispensable qualité.

Le premier chapitre présente et discute les contraintes que la croissance démographique impose à la production alimentaire et les conséquences prévisibles sur l'environnement. Les vrais problèmes liés à une urbanisation galopante et à de rapides changements de nos styles et de nos niveaux de vie sont examinés, depuis les changements dans les habitudes de consommation jusqu'aux avancées technologiques dans l'agro-alimentaire. Les progrès et les dangers des systèmes modernes de production végétale sont analysés de façon claire bien que pessimiste, de la productivité des sols et de l'utilisation des terres à la désertification et de la détérioration des ressources en eau au déséquilibre des écosystèmes. Les connaissances particulières de l'auteur dans le domaine de la santé et de l'alimentation animales et des systèmes d'élevage permet une présentation intéressante, lucide et simple du secteur de la production animale. La partie la plus originale du livre est probablement celle qui concerne la surexploitation des mers et des océans.

Le second chapitre s'intéresse aux influences des évolutions du climat sur la production alimentaire et la nutrition, notamment les effets indirects de l'activité humaine sur la production alimentaire et la pollution de la chaîne alimentaire et des réserves en eau.

Une dernière partie est consacrée à ce que l'on considère comme des maladies de l'homme liées aux déficiences nutritionnelles, aux déséquilibres alimentaires et à la dégradation des ressources alimentaires. La conclusion est d'un optimisme prudent. Il serait certainement utile de traduire cet ouvrage en anglais et en espagnol.

The epidemiology, diagnosis and control of helminth parasites

J. Hansen & B. Perry. 2nd ea., 1994. Addis Ababa, Ethiopia, International Laboratory for Research on Animal Diseases (ILRAD). ISBN 92-9055-703-1.171 pp.

Helminth parasites of ruminants are ubiquitous, with many tropical and subtropical environments of the world providing nearperfect conditions for their survival and development. Although these parasites are widely prevalent, the clinical signs evident in infected animals can be less obvious than those of other livestock diseases. Partly for this reason, gastrointestinal and other helminth parasite infections are among the most neglected areas of veterinary care in much of the developing world. The first edition of this handbook was written to help redress this imbalance.

The second edition of the handbook reviews the epidemiology of helminth parasites of ruminants and presents procedures and techniques for their diagnosis, survey and control. It has been enlarged to encompass a broader range of helminth species in a wider geographical area. The book is designed for routine use in all types of animal health institutions, including universities, research institutes and field laboratories, where diagnostic parasitology will help to improve and standardize diagnostic capabilities, as well as contribute to the collection and use of basic epidemiological data, the foundation for effective disease control programmes. In view of the value of effective helminth control in ruminant production systems throughout the world, FAO and the International Livestock Centre for Africa (ILCA) have joined the International Laboratory for Research on Animal Diseases (ILRAD) in publishing the second edition of this popular work.

Conservation of early domesticated animals of southern Africa

Irene Animal & Dairy Science Research Institute, Private Bag X2, 1675 Irene, South Africa. 136 pp.

This publication contains the papers presented during a workshop held at the Willem Prinsloo Agricultural Museum in Pretoria, South Africa, in March 1994. The idea behind this subregional conference was to discuss the state of the art of indigenous farm animal populations and their conservation in southern Africa. The aim was to develop the possibility of establishing a society with a constitution to promote and allow the assessment of the present distribution of endangered breeds and various domesticated local livestock and to sustain the awareness of the need for the conservation of genetic diversity.

An important variety of these early domesticated livestock still seems to be present in southern Africa, mostly surviving under difficult, if not poor, environmental and management conditions. With the introduction of modern selection techniques pushing towards maximum productivity and the importation of highly specialized livestock strains from Europe and North America, the local populations are now marginalized and less and less utilized. Concern over the present demise of these early domesticated local populations is growing and there is a great risk of animal genetic resource diversity loss.

The conference was opened by the director-general of the South African Department of Agriculture and introduced with a paper on the prevailing international philosophy and methodology of genetic conservation by Laurence Anderson of Rare Breeds International.

Following a most informative review of the archaeological evidence of the existing indigenous livestock on the southern tip of the subcontinent, a paper was presented on the prehistory and history of domesticated animals in the region, underlining the need to rescue the existing diversity. A report on the introduction of non-indigenous breeds of livestock completed the session.

Two papers emphasized the predominant methodologies for matters relating to the identification of animal breeds and the structuring of breeding systems for small populations.

From a practical regional point of view, a valuable report described the experiences and findings of a technical committee, appointed in 1985, to evaluate the contribution made by imported livestock and semen to animal agriculture in South Africa and the desirability of an in vitro germplasm bank for southern Africa. The committee also reviewed the relevant research and technology advances, as well as staff and funding needs. An interesting regional case-study underlined the need to follow, simultaneously with a higher productivity policy of imports and sophisticated national selection schemes, a parallel active conservation trend for local animal genetic resources.

Four case-studies completed the plenary sessions, the last one being an interesting approach to profitable and environment-friendly farming systems with local livestock in southern Africa.

Use of trees by livestock

Erythrina

R.T. Paterson. 1994. Kent, UK, Natural Resources Institute (NRI). 18 pp. ISBN 0-85954 381-1. Price: £2.00 (Ordering reference LG9).

Following the publications on Prosopis, Acacia, Gliricidia, anti-nutritive factors, Quercus, Cassia, Ficus and Calliandra, the Natural Resources Institute (NRI) has just published the ninth booklet in its series on the use of trees by livestock. Erythrina is a genus of some 108 species of leguminous shrubs and trees that are distributed widely throughout the tropics and subtropics. Several species thrive on waterlogged or poorly drained acid soils, which normally are inhospitable to most legumes.

Erythrina species have long been used as ornamentals, living fence posts, supports for vine crops, green manure and shade trees in coffee plantations. They have also been used for human food, medicinal purposes, personal decoration, fish floats and carving. Attention has now focused on their use as fodder trees, despite concern over the effects on livestock of a range of alkaloids and flavonoids occurring in the foliage.

Erythrina is rich in crude protein but the digestibility of the foliage is only about 50 percent. Many species are well accepted by livestock and there is considerable potential for using them as dietary supplements. They may be of particular use in areas where there is a lack of other high-quality fodder species because of soil acidity and lack of drainage.

This publication can be obtained from the Natural Resources Institute, Central Avenue, Chatham Maritime, Kent ME4 4TN, UK.

No charge is made for single copies sent to governmental and educational establishments, research institutions and nonprofit organizations working in countries eligible for British Government aid. Free copies cannot normally be addressed to individuals by name, only under their official titles.

Livestock for a small earth: the role of animals in a just and sustainable world

J. Aaker, ed. 1994. Washington, DC, USA, Seven Locks Press. ISBN 0-929765-28-1. 111 pp.

Fifty years ago, a United States farmer from the state of Indiana came up with the idea that rather than sending food/milk to feed the children of the developing and marginal areas of the world, what really was needed was a cow, a goat, a ewe, a fowl or a bee hive.

In June 1944, the first 18 heifers were shipped to a small village in Puerto Rico by what was later to become known throughout the world wide as the Heifer Project International (HPI). Since then, a flow of animals has taken place, but also more and more active technical support has been given to animal agriculture, farming system practices and food and nutritional development, even banking. Addressing local rural socio-economic problems in more than 110 countries has became HPI's routine activity.

This book was published to mark HPI's 50th anniversary. Written in easy-to-read and clear language, it defines the self-help philosophy and insight of the organization and tries, on the basis of the successes and failures of this extraordinary voluntarist's practical experience of 50 years, to explain the specifics of down-to-earth long-term sustainable rural development and agricultural aid programmes. It was not only meant to relate HPI's unique and original past contributions to the alleviation of hunger and poverty in many of the world's most marginal rural areas through the introduction and active support of the animal factor, but also to explain how socially just and environmentally supportive livestock development is feasible under these conditions.

The book is presented in two sections. The first part discusses the principles and possible benefits of sustainable animal agriculture, introducing the cornerstone ideas of a humane and socially just rural society. The second part develops in detail the process of the "self-help approach" and training needs for livestock programme planning on a small scale. It underlines HPI's main idea that "those that got help must eventually help others" and shows the overall need for an accountability process.

A list of selected references gives some direction for further reading.

As clearly stated in the foreword, this is by no means a handbook for academics. Instead, it is bedside reading for those interested in the benefits of a better understanding of the requirements of farm animals in relation to the people who need them, as well as a review of basic animal ethics in a changing environment.

Edited with imagination, this book can help national, regional and local policy-makers understand livestock-related problems as they truly exist, highlighting the pressing problems of the rural world. Local development and extension officers, farming and community leaders, and also students will find it useful and enlightening.

A SPEECH DELIVERED ON THE 50TH ANNIVERSARY OF THE HEIFER PROJECT INTERNATIONAL, 7 OCTOBER 1994: project testimonial by Digna Campos, El Temblor, Honduras

My name is Digna Campos and I live in the community of El Temblor in Honduras. I am 28 years old and have six children. I would like to tell you my personal story and that of my project.

I was born in Petoa, in the area of Santa Barbara, which is in the northwestern mountains of Honduras. My mother was from llamas, another village from the same area. My mother had eight children: six girls and two boys. She didn't send any of the girls to school, so I never learned to read or write. I was eight years old when my father died. When he died, we didn't have a place to live. My mother raised us by working as a maid, but she didn't earn a salary, only food for us. When I was nine years old, I started working and earned ten lempiras - about two American dollars - each month.

Two years after the death of my father, my mother found a new companion. He was really bad to all of us, so in order not to cause any problems for her, we left the house and we didn't even visit her. A few years later, when I was 15 years old, I began living with Victor. In the beginning we had lots of problems because he was always interested in other women. When I was 17 years old and had two children, he left us for another woman, and I suffered very much for this. Later he resumed to the house, but for a long time I didn't speak to him because I was so hurt. He asked for my forgiveness, but I answered that it was God to whom he needed to ask forgiveness and not me. We left the house of his father and rented a room in which to live, but we still had some difficulties. I decided to continue living with him because I didn't want my children to be raised without an education like I was.

After a few years I joined a women's group in the community that was supported by the World Food Programme of the United Nations. By being organized I was able to learn many new things. Victor was not very happy about me being part of this organized group. Later we had a problem with a promoter in a gardening project and I left the group.

Some time after this, 32 families in our community had the opportunity to obtain land from the National Agrarian Institute. Finally, in 1987, when we had the legal guarantee to 66 manzanas (112 acres), we started to work. The first thing we did was construct a house made of grass and straw. Soon after, a community group from the village of Cantiles told us about the Christian Commission for Development (CCD). They came to our new community to see if they could work with us. They visited our community twice and talked with us. They decided to start working in the area of health, and leaders were chosen. We had 100 percent malnutrition in our kids and sometimes even in the adults. It was decided that a priority for El Temblor (which means "earthquake") was a dairy goat project.

We started with a collective project and received nine goats in 1989. Some members of the community received training, but we found that not everyone took care of the goats well when it was their turn. Some of the older people hired children to watch the goats, but they were always playing with the baby goats, interrupting their nursing. We also started to think about the use of medicinal plants. When we developed problems in the goat project, we decided to change to private ownership by each family. My family received one of the goats in 1991 and now we have seven. I have not yet passed on my gift because I have been helping a neighbour whose goat always has males. Now that everyone in my community has goats, my goat to pass on will soon be ready and will go to another village in Santa Barbara.

Now my children and all the children of the community drink milk every day. Before they only drank it once every five or six days. After visiting the home of Gloria and Tim Wheeler several times, I now use the milk to make cheese. Before, almost all of the children were malnourished, but now we don't have severe cases of malnutrition. The few children who remain malnourished have improved from third-degree to first-degree malnutrition. We also have consumed some of the animals and several community members have sold animals. We use organic fertilizer on coffee plants and other crops. My son Arturo takes care of the goats and they obey him more than the rest of us. He gives them salt from the kitchen and corn husks; maybe because of this they like him.

Also, through their work with CCD and Heifer Project International (HPI), the women of the community have started to recognize their important value as women. We listened to talks by both the men and the women. I have seen in the case of my own household that there have been changes. Victor used to be a man who had to be served his food, even if it was all prepared he wouldn't serve himself. Now he cleans the house and bathes the children. And the children are also included in household chores now.

Recently we also received assistance in starting a collective cattle project in the community. The project began on 27 November of last year, when we received six animals. One has already calved and the others will do so next month. Perhaps some of these animals were gifts from people like you. We are all very grateful to CCD and HPI. The other group members and I appreciate very much the visits from people who come to see us (work study groups) to understand the needs that we have. Through CCD we have also improved our houses. We built five new houses this year and will build more next year through this effort involving all of the people of our village.

I used to wake up at 3 o'clock in the morning, but now, thanks to the women's programme, I get up at 5 o'clock. Victor gets up first to make the tortilla mix and sweep the kitchen, and when the water is boiling for coffee he calls me to get up. Other women who are not organized ask me why I look so young. I joke with them that it is because we now divide the work in our family and I don't have to work as hard. I sleep well now because Victor and I no longer worry about where each of us is going when we leave the house. I rest more and there is a better future for my children.

On behalf of my village and many other Hondurans who benefit from your livestock and human development projects, I want to thank you. Now we have hope.

CORRIGENDA

In World Animal Review No. 82, "Better feed for animals: more food for people", the caption for the cover photo, by C. Dalibard, should have read: Sugar-cane tops constitute an excellent and very palatable fodder for ruminants.

On the second page of the Convents, the photograph, by R. Sansoucy, should have been accompanied by the caption: Sweet potato leaves are an excellent source of protein for pigs fed on sugar-cane juice.

The note on p. 24, "FAO activities for the sustainable use of locally available feed resources", should have been placed on its own on p. 104. The Editor apologizes to the author for this oversight.

RECTIFICATIF

Dans le numéro 82 de la Revue mondiale de zootechnie, sur le thème «Meilleure alimentation animale: plus de nourriture pour l'homme», la photo de la couverture, de C. Dalibard, aurait dû porter la légende suivante: Les bouts blancs de canne à sucre constituent un excellent fourrage très apprécié par les ruminants.

La photo de la page 2 du sommaire, de R. Sansoucy, aurait dû être accompagnée, quant à elle, de la légende suivante: Les feuilles de patate douce sont une excellente source de protéines pour les porcs recevant du jus de canne à sucre.

Par ailleurs, l'encadré de la page 24, intitulé «FAO activities for the sustainable use of locally available feed resources», aurait dû apparaître séparément à la page 104. Le Rédacteur en chef prie l'auteur de bien vouloir excuser cette méprise.

FE DE ERRATAS

La fotografía (de C. Dalibard) de la cubierta del número 82 de la Revista mundial de zootecnia sobre el tema «Con mejores piensos, mas alimentos pata la población», debería haber llevado la siguiente leyenda: Las puntas de caña constituyen un forraje excelente y muy palatable para los rumiantes.

La fotografía (de R. Sansoucy) de la página 2 del Indice debería haber estado encabezada por la siguiente leyenda: Las hojas de batata constituyen una excelente fuente de proteínas para cerdos alimentados con jugo de caña de azúcar.

El recuadro de la página 24, «FAO activities for he sustainable use of locally available feed resouces», debería haber figurado por separado en la página 104. El Redactor en jefe pide al autor dispensar esta equivocación.

A systematic approach to tsetse and trypanosomiasis control - Approche systématique de la lutte contre la mouche tsé-tsé et la trypanosomiase

The impact of trypanosomiasis on sustainable agricultural production is of growing concern in the context of human population increase and the precarious food security situation in many countries in Africa. The papers presented in this publication formed the basis for the deliberations of FAO panels of experts convened to advise the Organization on a systematic approach to tsetse control and to recommend a globally concerted effort aimed at alleviating the disease.

Les effets de la trypanosomiase sur la production agricole durable sont de plus en plus préoccupants pour de nombreux pays d'Afrique confrontés à une forte croissance démographique et à une situation alimentaire précaire. Les documents reproduits dans cette étude ont servi de base aux débats des Groupes d'experts de la FAO réunis pour conseiller l'Organisation sur une approche systématique de la lutte contre la mouche tsé-tsé et pour recommander une action globale concertée contre la trypanosomiase.
