This book was released on 1975 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: En la Estación Experimental Quilamapu Chillán, se realizó un experimento con el objeto de obtener antecedentes iniciales que permitan delinear un sistema de producción de carne en base a novillos Hereford nacidos durante la primavera en la región de la costa y llevados al valle central (Chillán) después del destete, para completar peso de mercado. Pasando después por tres etapas: 1. Primer invierno, los novillos se sometieron a 2 tratamientos de alimentación: a. pastoreo invernal más coseta seca-afrecho de raps, con una ganancia de 0,62 kg/nov/día y b. pastoreo invernal más heno, con una ganancia de 0,36 kg/nov/día.; 2. Pastoreo primavera-verano-otoño y 3. Engorda final corta. Los principales resultados son: -En el tratamiento b los animales demoraron 20 días más que el tratamiento a, para lograr 400 kg de peso vivo.; -Se produjeron novillos Hereford de 400 kg de peso vivo a los 21-21 1/2 meses de edad. Para alcanzar lo anterior, fue necesario una engorda corta (2-2 1/2 meses) durante el segundo invierno.; -El bajo peso de los terneros al destete parece ser la principal limitante para alcanzar los 400 kg P.V. sin engorda final con suplementos en este sistema.; -Mediante alimentación basadas en forrajes, fue posible obtener una producción de carne de 750 kg de peso vivo/há. en el valle central.; -Debido al efecto de crecimiento compensatorio no se justifica tratar de obtener altas ganancias de peso durante el primer invierno.

Download or read book Silvopastoral Systems in Southern South America written by Pablo Luis Peri and published by Springer. This book was released on 2016-03-02 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

Download or read book Long Distance Transport and Welfare of Farm Animals written by Michael C. Appleby and published by CABI. This book was released on 2008 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Around 60 billion animals are bred for food each year worldwide and more than a billion are transported, often over long distances, every week. However, awareness and understanding of animal welfare, the factors that affect it and the correlation between it and other issues such as food safety and quality are increasing. Long distance transport can cause both physical and mental problems in animals and promoting animal welfare will be beneficial to both the animals and the agricultural and processing industries. In conjunction with a global coalition of NGOs working on animal transport and welfare, this volume brings together studies from well known animal scientists and researchers to review the implications and necessity of long distance animal transport for slaughter. Authoritative reports on regional practices are combined with discussions of the science, economics, legislation and procedures involved in this practice. This review will be essential for researchers and professionals within animal production and welfare as well as veterinary science.
