A.  aThe role of ruminants in support of man.  aMorrilton, Arkansas: Winrock International Livestock Research and Training Centerc1978  a136 p.  aAbstract : This publication is the result of a research project of Winrock International, with the following broad objectives: (1) to produce an inventory, on a regional basis, of the world ruminant population, its productivity, feed requirements and feed resources; (2) to identify constraints on efficiency; (3) to develop priorities for research, training and development; (4) to provide an information base for use in developing private and public investment policies. There are 8 chapters, with the following headings: (1) The role of ruminants in support of man; (2) Ruminant resources; (3) Nutrient resources for ruminant production; (4) Ruminant health; (5) Genetic improvement of Ruminants; (6) Non-biological constraints on production; (7) Future economic demand for ruminant products; (8) Meeting the demand for ruminant products. In an appendix, data are tabulated on ruminant populations and productivity, metabolisable energy requirements, land areas available for ruminant and arable production, world pasture distribution, and consumption of ruminant products. There is a 3 page summary, including conclusions. The basic conclusions on the current value and future importance of ruminants were that the human population (1) does not want to give up ruminants, (2) need not give them up, and (3) should not give them up.&ltnew para&gtADDITIONAL ABSTRACT:&ltnew para&gtThis publication is divided into the following chapters: the role of ruminants in support of man; ruminant resources; nutrient resources for ruminant production; ruminant health; genetic improvement of ruminants; nonbiological constraints on production; future economic demand for ruminant products; meeting the demand for ruminant products. Estimates and descriptions of world land use and forage resources from permanent pasture and meadow are given. Forage production from non-agricultural lands, food resources including forages, crop residue, oilseed meal from arable lands, agri-industrial by-products, relative importance of energy sources, other nutrients and the world outlook for ruminant food resources are described and discussed.&ltnew para&gtADDITIONAL ABSTRACT:&ltnew para&gtThe main aims of the study which produced this report were to provide an inventory of the worlds ruminant population, their output and productivity and their feed requirements, and to assess the worlds total feed resources for these ruminants projecting some of the values to 2000 AD. Also to identify the constraints on improving the level of efficiency of ruminant production including feed resources, health problems, genetic potentials, capital, market and institutional inefficiencies. Summary findings are presented in very readable form, in 8 chapters.  aAnimal ecology  aAnimal production  aDomestic animals  aLand use  aLivestock  aPlant nutrition  aRuminant nutrition  aCaprino  aCarne  aDoença animal  aLeite  aNutrição animal  aOvino  aProdução animal  aRuminante  aBubalino  aPopulations  aRuminant  aWorld1 aHODGSON, H.
