No results found.The purpose of this Manual is to assist researchers in developing countries, especially those in the tropics, to develop livestock feeding systems based on the available resources which are mainly crop residues, dry and/or mature pastures and agroindustrial byproducts. The need for an alternative to the traditional methods of feed analysis was first raised at an Expert Consultation on New Feed Resources held in FAD Headquarters, Rome in November 1976. At that meting data were presented to show that the conventional feeding standards, derived fram research with feeds of temperate country origin, were of limited value when applied to the crop residues, dry pastures and sugar-rich agroindustrial byproducts which made up the feed inventory in most tropical countries. As a follow-up to this meeting a small network involving institutions frcm Cameroon, Nigeria and Senegal was set up by FAO to promote research on several locally available crop residues and agroindustrial byproducts. An FAO Seminar was organized in collaboration with the International Livestock Centre for Africa (ILCA), and held in Dakar, Senegal in September 1981. At this meeting, which addressed specifically the problems of utilizing feed resources in Africa, the first results of the Network were presented. During this discussion it became apparent that apart from the conceptual difficulties of applying in Africa the animal nutrition knowledge gained in Europe and North America, there were other serious limit ations of lack of infrastructure, especially laboratory equipment and the means of servicing, coupled with irregularities in electricity supplies. Ccmmunication among researchers working with tropical feed resources was found to be another limiting factor. It was resolved to extend the activities of the original Network to other countries in Africa and to join forces with the recently formed African Research Network on Agroindustrial Byproducts (ARNAB). It was proposed that the International Liv estock Centre for Africa, with its ccrnprehensive documentation and laboratory analytical facilities'. should provide the coordinating role. The conclusions and reccmmendations from the Dakar meeting were that there was a need to develop more appropriate procedures for evaluating crop residues and byproducts, taking into account the limited laboratory facilities of most institutions in Africa; and the nature of the livestock production systems, where multi-purpose traits such as draught power, ability to survive extended dry seasons and rural (transhumant) milk supply were greater relevance than the technologies from industrialized countries which emphasize specialized meat and milk production. The third meeting of the series was also organized by FAO and ILCA at Addis Ababa in March 1984 and addressed the specific issue of methodologies both for feed evaluation and research on livestock feeding systems. The advantages of promoting communication amoung different tropical regions w as emphasized by drawing on participants from Latin America, Asia and Africa to share their expaeriences with each other and with colleauges from Europe and North America, which have specific expertise to offer in the subject area. Consultation was charged with producinq two documents: the Proceedings dealing with the State of the Art of research into crop residues and byproducts; and a practical manual to serve as a guide for field workers, especially those operating with minimum facilities in terms of laboratory and literature support. Ruminants have received more attention than monogastrics. This is because, in tropical countries, they are generally the more important species from both the numerical and socio-econamic viewpoints. Furthermore, their physiological adaptations enable them to harvest and digest feeds, which are not available to the monogastric species, and which ipso facto are not competitive with humans for their food supply. -

No results found.A Technical Consultation on New Feed Resources was held at FAO Headquarters, Rome in 1976. This Consultation paid special attention to the potentialities of poor quality roughages derived from agriculture, the quantities available, and the improvementof the nutritive value of such roughages by the use of physical, chemical and biological methods. Attention was also given to agro-industrial by-products such as molasses, pulps, processed cassava and potato residues, oilcakes, milling by-produc ts, etc. along with the by-products of wood and the cellulose industries and to the recycling of animal wastes. In order to support studies on increasing the rate of utilization of crop residues and agro-industrial by-products in animal feeding in Africa, the Animal Production and Health Division of FAO, in collaboration with several research institutes in that region, such as those in Cameroon, Nigeria and Senegal, set up in 1973 a network or the subject of 'West Africa. This network was to assist the activities being undertaker. in connection with this subject in African countries and to promote the exchange of research experience and other related information between African countries. To support the African network on better feed utilization, FAO in 1981 in collaboration with the International Livestock Centre for Africa MCA) organized the FAO/ILCA Workshop on Crop Residues and Agro-Industrial By-products in Animal Feeding, at Dakar, Senegal. About 40 scientists from 15 different African countries attended this workshop. The Workshop made many recommendations and laid down guidelines for the future activities of the African network. It stressed the importance of appropriate support and encouragement being given to the scientists undertaking research work on the subject at various institutes in different countries of Africa. The Dakar 'Workshop of 1981 made a recommendation amongst others that an Expert Consultation should be organized in ord er to establish guidelines for research on crop residues and agro-industrial by-products and that this consultation should produce a booklet in which would be described the detailed methodology employed and which would contain a compilation of all the known appropriate methods of analysis. In 1983, the Animal Production and Health Division of FAO included this Expert Consultation in their regular programme budget for the period 1984-1985. As the subject features prominently in the pro gramme activities of ILCA the Director, Dr. Brumby, expressed interest in collaborating with FAO in organizing such an Expert Consultation at ILCA Headquarters in Addis Ababa, Ethiopia. In the autumn of 1983, the Animal Production and Health Division of FAO sent a consultant (Dr. Preston) to review the present situation on research being undertaken on the utilization of crop residues and agro-industrial by products in selected African countries, nanely Carneroon, Nigeria and Senegal, and to ascertain how ILCA experts could cooperate in such research work. Dr. Preston's findings will serve as a background paper for the Expert Consultation. FAO and ILCA invited. scientists from various countries of the world to participate in the Expert Consultation, the main objectives of which were: to outline and discuss the present situation in regard to the kind of research going on in developing countries at the present time and the research methodologies which might suitabl y be employed in such research; to make recommendations and set down guidelines for research on crop residues and agro-industrial by-products for the guidance of research workers in developing countries in order that useful results can be achieved from their work. -
BookletEthiopia | Availability and utilization of agroindustrial by-products as animal feed | 2018 2019
Also available in:
No results found.One of the major constraints for the very low production and productivity of livestock in Ethiopia is the poor quality and inadequate quantity of available feed. Agro-industrial by-products (AIBPs) can play an important role in meeting the widely prevalent feed shortage in the country. The AIBPs are usually less fibrous, rich in energy and/or protein contents. They have high digestibility and energy values compared with other classes of feed resources. The major AIBPs produced in Ethiopia include by-products from flour millings, sugar factories, edible oil processing factories, breweries, and abattoirs. These by-products play a vital role in the feeding of livestock mainly in urban and peri-urban livestock systems. The spatial and temporal availability of AIBPs in different parts of Ethiopia has not been quantified. Information on the utilization of such resources is also scanty. Data on availability of these resources is important for developing and using appropriate feeding strategies, improving livestock production and productivity, enhancing the efficiency of AIBPs utilization, decreasing burden on the environment and promoting technologies that further circular economy. This study was aimed at assessing the spatial and temporal availability of major AIBPs and their use as livestock feed. Information on storage and transport of these by-products has also been recorded with the aim to identify ‘hotspots’ at which the wastage takes place, and to suggest ways to reduce it.
