VALENTE and published by . This book was released on 1977 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Este trabalho foi realizado no Departamento de Zootecnia da Universidade Federal de Vicosa, o envolveu duas variedades de milho (Zea mays L.): 'Maya IX' e Dentado Composto VIII', e quatro variedades de sorgo (Sorghum bicolor (L.) Moench): 'Start', 'Dekalb FS-24', 'TE-Silomaker' e 'Santa Elisa'. o objetivo foi comparar as variedades de milho e/ou de sorgo quanto a produtividade da forragem a ensilar e quatro as caracteristicas e valor nutritivo das silagens resultantes. No ensaio de producao usou-se um delineamento de blocos ao acaso, com quatro repeticoes, em parcelas de 20 x 20 m, sendo de 349,6 m2 a area util de cada unidade experimental. O plantio foi feito em 30 de outubro de 1975, usando-se espacamento de 0,80 m entre fileiras, o que proporcionou, apos o desbaste, uma densidade media de 75.000 e 187.500 plantas/ha para as variedades de milho e de sorgo, respectivamete. A adubacao de plantio consistiu na aplicacao de 500 kg/ha de uma mistura composta de 150 kg de sulfato de amonia, 300 kg de superfosfato simples e 50 kg de cloreto de potassio. Quarenta e cinco dias apos a plantio foram aplicados 250 kg/ha de sulfato de amonia como adubacao em cobertura. O corte do material, para a ensilagem, foi feito quando os graos estavam pastosos e mais de 50% dos graos estavam firmes, para as variedades de milho e de sorgo, respectivamente. O material foi ensilado em 24 silos cilindricos, subterraneos, com capacidade unitaria de 2,7 m3, empregando-se um delineamento inteiramente casualizado. Durante a ensilagem (...).

Available in PDF, EPUB and Kindle. Book excerpt: Agriculture and Industry in Brazil is a study of the economics of Brazilian agriculture and industry, with a special focus on the importance of innovation to productivity growth. Albert Fishlow and José Eustáquio Ribeiro Vieira Filho examine technological change in Brazil, highlighting the role of public policy in building institutions and creating an innovation-oriented environment. Fishlow and Vieira Filho tackle the theme of innovation from various angles. They contrast the relationship between state involvement and the private sector in key parts of the Brazilian economy and compare agricultural expansion with growth in the oil and aviation sectors. Fishlow and Vieira Filho argue that modern agriculture is a knowledge-intensive industry and its success in Brazil stems from public institution building. They demonstrate how research has played a key role in productivity growth, showing how prudent innovation policies can leverage knowledge not only within a particular company but also across whole sectors of the economy. The book discusses whether and how Brazil can serve as a model for other middle-income countries eager to achieve higher growth and a more egalitarian distribution of income. An important contribution to comparative, international, and development economics, Agriculture and Industry in Brazil shows how the public success in agriculture became a prototype for advance elsewhere.

Book excerpt: I wrote this book because I believe that the welfare of animals is a very important subject but one about which there is a of confusion and muddled thinking. I wanted to great deal write a book which straightened out some of the confusion by looking in detail at one particular problem: how to recognize animal suffering. The book is written for anyone interested in animals and the controversies over how human beings should treat them. I have tried to convince people who might otherwise feel that science had only a rather sinister connection with animal welfare that the scientific study of animal suffering has, in fact, a major and positive contribution to make. It can give us an insight into what animals experience and this, in tum, may help us to alleviate their suffering. At the same time, I have tried to write a book that will be of at least some use to scientists. The chapters which follow pro vide an outline of the biological approach to animal welfare. I have also attempted to show sceptics that it is possible to study animal suffering without sacrificing standards of scien tific procedure. Perhaps some may even come to share my belief that the study of the subjective experiences of animals is one of the most fascinating areas in the whole of biology, as well as being of great practical and ethical importance.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytomass and Primary Production of the Various Vegetational Zones and of the Entire Biosphere The biosphere is that thin layer at the earth's surface in which living organisms exist and biological cycling takes place. It includes the upper horizons of the soil in which plants root, the atmosphere near the ground, (insofar as organisms penetrate this space), and all the surface waters. More than 99% of the earth's biomass is phytomass, to which we shall limit our discussion. Amounts of phytomass are distinctly related to vegeta tional zones. Because accurate determination of phytomass and primary production is difficult, only gross estimates have been available until recently. However, in 1970, Bazilevich et al. published (in Russian) more accurate calculations, based on the rapidly accumulating literature, for the various thermal zones and bioclimatic regions of the earth. These authors calculated mean phyto mass and mean annual primary production for the various regions as dry mass (in tons) per hectare. On the basis of measurements of the areas covered by the individual regions, excluding rivers, lakes, glaciers, and permanent snow, total phytomass and total annual primary production for the various regions were obtained (see table). The sum of these figures is the phytomass and annual production of the land surface of the earth. In addition, the table gives corresponding data for the waters of the earth. The values involved are potential i. e. , they are based on natural vegetation uninfluenced by man.
