The Rabbit: Husbandry, Health and Production (New Revised Version) ISBN 92-5-103441-9 Food E5 and zco Agriculture Organization of the United Nations THE RABBIT Husbandry, health and production Rabbits reared with techniques adapted to specific environments can do much to improve the family diet of many of the neediest rural families, at the same time supplying a regular source of income. The purpose of this work is to bring to- gether as fully and objectively as possible all the available data on rabbit husbandry, health and production. It is also intended as a contribution to the preparation and execution of rabbit development pro- grammes, particularly in developing countries. A team of scientists from the French National Institute for Agricultural Research (INRA), a world-renowned rabbit author- ity, was marshalled to cover the many and varied aspects of rabbit production.

This is not only because of food deficits and inadequate distribution: the incomes of the poorest are too small to allow them to procure wholesome food in sufficient quantities. Livestock production is a major component of farm economies in developing countries, contributing not only food but also hides, fibres, fertilizer and fuel, as well as a modest, interest-producing capital which can easily be mobilized when unforeseen needs arise. In addition, livestock, whether large or small, are part of the social and cultural reality of several million srnall farmers, for whom husbandry represents an element of economic stability and sustainability. Bothhuman and livestock populations have grown considerably in the last 30 years, but the rates in developed and developing countries are not comparable. Whereas the global human population has risen by 75 percent since 1960, in the developing countries the rate of increase was 97 percent and in the industrialized countries 28 percent. All species of livestock populations increased, but monogastrics (pigs and poultry) much more than ruminants. Small-animal husbandry can be a very lucrative operation for both landed and landless small farmers; providing work for women, children and the handicapped (the least privileged social strata), producing substantial income and helping to upgrade the family diet. Many small domesticated species (guinea-pigs, capybara, cane rats, etc.) meet these objectives, but rabbit husbandry isfar more prevalent, particularly in the Mediterranean area. Certain traditional rabbit production systems particularly adapted to hot, dry, semi-arid countries have been successfully developed. Backyard rabbitries are particularly well suited to small farmers, whether they own land or not. The advantages are closely related tothe reproductive and feeding behaviour of rabbits and the fact that the species is both profitable and easy to integrate: as a small monogastric herbivore, the rabbit easilyaccommodates a fairly wide range of cellulose-rich foods; it is adaptable to the family diet and food preservation techniques available on small rural and peri-urban farms; it is highly prod.uctive in terms of offspring (kg /year dam) thanks Lo mating-induced ovulation, short gestation and lactation periods and great prolificacy; it produces highly nutritious, low-fat, low-cholesterol meat; it is easy to transport and market and the recurrent costs for maintaining animals beyond the optimum marketing age are low; labour costs are low and the work can be done by family members: women and children, or perhaps aged or handicapped people, usually the most vulnerable and least privileged social strata, for whom rabbit husbandry, iv like that of other small animals, represents an attractive and remunerative occupation; it represents a contribution to the family income; investment is low: infrastructure and equipment can easily be put together by the breeder and not much space is needed. Backyard rabbitries are the perfect answer to today's demand for sustainable development projects. For this reason, the Food and Agriculture Organization of the United Nations (FAO) and governmental and non-governmental development organizations have given firm and virtually universal support to rabbit projects in the developing countries. In the last ten years, FAO's Animal Production and Health Division (AGA) has supported and developed rabbit projects in Egypt, Ghana, Guinea-Bissau, Equatorial Guinea, Haiti, Mexico, Rwanda, Sao Tome and Principe and the Democratic Republic of the Congo (former Zaire). However, projects which have been successful have not had the expected catalytic effect and others have heavily regressed or completely disappeared. It would be a good idea to pinpoint the reasons for these failures and seek the most appropriate solutions before attempting to relaunch such activities. Constraints may concern: social, cultural and economic factors: customer acceptance of rabbit meat and ease of marketing; a lack of local resources available for balanced, low-cost, locally adapted rations; the existence of rabbit housing and management styles that inhibit the range of rabbit territorial, social, sexual, material and feeding behaviours; the presence of diseases representing a set of syndromes, rather than specific pathologies: if so, the appropriate approach would be an ecopathological one; breeder training: breeders may be unfamiliar with this species, which has very different behavioural characteristics from other domesticated species. Training should include useful theory and solid practical apprenticeship. By the year 2010, the world population will have risen from the present 5.4 billion to 7.2 billion, moving past nine billion by 2025. This increase will be felt mainly in the developing countries, where the corollary will be sizeable growth of the peripheries of urban conurbations, increased pressure on available land and major changes in the composition of animal populations. There will also be substantial impact on available natural resources and on the future demand for livestock products. This will have a profound effect on the choice of feed resources and livestock systems. More land will have to be allocated for food production, reducing the feed resources (natural rangeland, pastures, forage) available to feed this growing population, as can already be seen in Asia. Even so, appropriate technology can release additional harvest residues and agro-industrial by-products which can be used for livestock feed. Clearly, enhanced food production requires more efficient utilization of natural resources and the development of alternatives such as rabbit husbandry. This is why this manual, first published in 1984, is now being reissued. This very successful publication, translated into English and Spanish and reissued in 1990, has V long been out of print. An update thus became imperative in light of the major new developments and progress in rabbit husbandry in the last ten years. Publication of the handbook, delayed for many months, coincided with the Sixth World Rabbit Congress held in Toulouse from 8 to 12 July 1996. This meeting reported on the latest and best rabbit technologies, as well as those which can contribute effectively to food self-sufficiency in low-income food-deficit countries through sustainable pro- duction models. FAO is indebted to the National Institute for Agricultural Research (INRA) team under the leadership of Franqois Lebas for their contribution to this edition, their fine work and the many concrete instances of fruitful, joint collaboration over the last few years.

Centro de Estudios Avanzados en Ecología y Biodiversidad (CASEB). email: [email protected] ABSTRACT This work analyses the relationship between human beings and their environment taking into consideration the adjustment and eventual invasion of rabbits in Chile. It argues that in the long run, human actions have unsuspected effects upon the environment. In fact rabbits were seen initially as an opportunity for economic development because of the exploitation of their meat and skin. Later, rabbits became a plague in different areas of Central Chile, Tierra del Fuego and Juan Fernández islands, which was difficult to control. Over the years rabbits became unwelcome guests in Chile. Key words: Environmental History, biological invasions, European rabbit, ecology and environment. RESUMEN Este trabajo analiza las relaciones entre los seres humanos y su ambiente, a partir de la historia de la aclimatación y posterior invasión de conejos en Chile, constatando que, en el largo plazo, las acciones humanas tienen efectos e impactos insospechados sobre el medio natural. En efecto, si bien inicialmente los conejos fueron vistos como una oportunidad de desarrollo económico a partir del aprovechamiento de su piel y su carne, pronto esta especie se convirtió en una plaga difícil de controlar en diversas regiones del país, como Chile central, Tierra del Fuego e islas Juan Fernández.

Slow production of and limited land availability for ruminant animals, high feed cost and disease threats, including bird flu, in poultry production caused a significant raise of rabbit farming in Asia, and particularly in many areas in Asean countries. A drastic increase of rabbit farming and number of farmers occurred in Asia especially in China. Most of farms operations are small in scale and fed primarily on forage and by product feeds.

  • State-Of-The-Art on Use of Insects As Animal Feed
    State-of-the-art on use of insects as animal feed Harinder P.S. Makkar1, Gilles Tran2, Valérie Heuzé2 and Philippe Ankers1 1 Animal Production and Health Division, FAO, Rome 2 Association Française de Zootechnie, Paris, France Full reference of the paper: Animal Feed Science and Technology, Volume 197, November 2014, pages 1-33 Link: http://www.animalfeedscience.com/article/S0377-8401(14)00232-6/abstract http://dx.doi.org/10.1016/j.anifeedsci.2014.07.008 Abstract A 60-70% increase in consumption of animal products is expected by 2050. This increase in the consumption will demand enormous resources, the feed being the most challenging because of the limited availability of natural resources, ongoing climatic changes and food-feed-fuel competition. The costs of conventional feed resources such as soymeal and fishmeal are very high and moreover their availability in the future will be limited. Insect rearing could be a part of the solutions. Although some studies have been conducted on evaluation of insects, insect larvae or insect meals as an ingredient in the diets of some animal species, this field is in infancy. Here we collate, synthesize and discuss the available information on five major insect species studied with respect to evaluation of their products as animal feed. The nutritional quality of black soldier fly larvae, the house fly maggots, mealworm, locusts- grasshoppers-crickets, and silkworm meal and their use as a replacement of soymeal and fishmeal in the diets of poultry, pigs, fish species and ruminants are discussed. The crude protein contents of these alternate resources are high: 42 to 63% and so are the lipid contents (up to 36% oil), which could possibly be extracted and used for various applications including biodiesel production.

  • Economics of Aquaculture Feeding Practices in Selected Asian Countries Economics of Aquaculture Feeding Practices in Selected Asian Countries
    ISSN 0429-9345 505 FAO FISHERIES TECHNICAL PAPER 505 Economics of aquaculture feeding practices in selected Asian countries Economics of aquaculture feeding practices in selected Asian countries This technical paper provides an analysis of the economic implications of, and the reasons for, adopting various feeding practices for different fish species and aquaculture systems in Asia. It consists of case studies in six Asian countries (Bangladesh, China, India, the Philippines, Thailand and Viet Nam) and an overall synthesis ending with conclusions and recommendations. The systems studied include extensive/traditional, semi-intensive and intensive farms for a number of different species including sutchi and pangasiid catfishes (Bangladesh and Viet Nam), hybrid catfish (Thailand), carp polyculture (India and China), prawn and milkfish polyculture (the Philippines). The work identifies the principal input costs, assesses the economic rates of return (gross and net margins), returns to labour, land and capital, gross and net total factor productivity, and break-even prices and production. For the most part, intensive farms applying industrial feeds attained the highest economic returns, although not necessarily the highest benefits. In many cases, feed costs were extremely high, accounting for over 80 percent of the total. Feed cost, feeding rate, stocking rate, recovery or survival rate and fertilizer cost were identified as the key variables in influencing production. Use of intensive farming was consistent with strong farmer education and good extension practices. It is expected that the results of these studies will assist in adopting appropriate feed management strategies depending on the availability of inputs and the level of technical know-how of the farmers.

  • Flash Notes – Animal Fibre – Fibre to Fabric
    Flash Notes – Animal Fibre – Fibre to Fabric Cloth is made from fibres. FIBRES Fibres are threads which are used to make various materials. These thread like structures are either obtained from living things or are created artificially. 1. Artificial Fibres / Synthetic Fibres : Also called Man – Made Fibres. They obtained artificially. Ex: Nylon (Use for making ropes / clothes), Rayon and polyester (for clothes etc.) Advantages: Economical, Dry faster (do not soak/absorb water), Wrinkle free (hence easy to maintain), Durable. They are not limited and expensive as compared to natural fibres . 2. Natural Fibres : Natural fibres are obtained from living things that exist in nature. They are obtained either from plants and animal sources. There are 2 types of natural fibres – 1. Plant/ Vegetable fibres 2. Animal fibres FIBRE OBTAINED FROM Flax, jute and Hemp(plant fibre) skin surrounding the stem of the respective plant and hence called skin fibres. Coir (plant fibre) a coconut fibre which is obtained from coconut. Tree Wood (plant fibre) obtained from stocks of different plants like bamboo, straw of wheat or rice. Wool(animal fibre) obtained from a lot of animals like sheep Silk(animal fibre) Silkworm Cotton(plant fibre) obtained from seeds of cotton plants. Advantages : Biodegradable, Comfortable to wear. Disadvantages: Expensive (like Silk), Difficult to maintain (Wool shrinks too), Get wrinkled (Cotton), Non- durable (Jute hard). www.experihub.com Page 1 WOOL - The hair on the body of a few animals traps lot of air and since air is a poor conductor of heat, it shields the body from cold and keeps it worm.
