Also available in:
No results found.Meat and meat products are concentrated sources of high quality protein and their amino acid composition usually compensates for shortcomings in the staple food. They supply easily absorbed iron and assist the absorption of iron from other foods as well as zinc, and are rich sources of some of the vitamins in the B group. By providing such nutrients, meat consumption can alleviate common nutritional deficiencies. The production of animals for meat can be integrated into the overall food system without competing directly with crops for human food; it enables utilization of land that is difficult to cultivate, and supplies valuable by-products as well as improving the fertility of the soil. The appropriate utilization or expansion of existing sources of meat calls for coherent development of a complex system of production, processing and marketing, including aspects of finance and expertise for construction and operation of meat plants, and means of storage, meat preservation, tra nsport and marketing. In many regions in developing countries meat production is carried out with efficiency, and slaughter and processing are based on many of recent scientific developments. However, even in industrialized countries there is often considerable room for improvement. In other regions methods are less advanced, with poor control of sanitation, leading to considerable loss of products as well as to the risk of meat borne diseases. Improvements of techniques of slaughter and pr ocessing, especially in hygiene, would result in greater yields and higher profits. These would also provide the incentive for increased production. -
Book (stand-alone)Legume Trees and other Fodder Trees as Protein Sources for Livestock 1992
Also available in:
No results found.Fodder trees and fodder shrubs have always played a significant role in feeding domestic animals. In fact, trees and shrubs are increasingly recognized as important components of animal feeding, particularly as suppliers of protein and especially in harsh environmental conditions. In such situations, the available grazing is not generally sufficient to meet the maintenance requirements of animals, at least for part of the year. This occurs, for example, in some mountainous regions and in the dry tropicswhere the grazing is also sometimes very degraded. Thus, in extensive animal production systems in the dry areas of Africa, it is generallye stimated that ligneous materials contribute up to 90% of production and account for 40-50% of the total available feed. Such figures illustrate the existing and urgent need not only for better knowledge but also for better use of such potential, particularly in the context of environmental degradation which is affecting our planet. On the other ha nd, in the humid tropics of Latin America, the South-cast Asia and Africa, foddersfrom trees and shrubs from leguminous species - are beginning to be utilized more dietary nitrogen supplements for ruminants. In this respect, new a significant move to look for new sources of protein from shrubs. However, given the increasing demand for forage and availability of low quality basal feed materials which require protein supplementation, high protein fodders from leguminous trees and shrubs could have a much more significant role in animal feeding systems throughout the developing world. In this respect, there is a need for more research to develop technically viable solutions. These solutions must also be economically and socially acceptable; they must preserve natural resources and protect the environment. In other words, the challenge is the sustainable development of fodder trees and shrubs.........
