This book provides a comprehensive review of in ovo techniques and treatments in poultry eggs, which are aimed at improving embryonic development and decreasing economic losses in poultry farms. The book is divided into four chapters, which address the basics of in ovo techniques and sites of in ovo injection, nutrient utilisation for the development of the chick embryo, the role of early in ovo feeding for the chick embryo, and applications of in ovo technology for various nutrients and biological supplements in poultry. Thanks to the authors’ broad experience in the fields of research and education, this work contains up-to-date, scientifically validated information on in ovo techniques. Its structured format and clear, didactic style are aimed at facilitating the reader’s understanding. Altogether, this is a must-have for nutritionists, poultry breeders and farmers, veterinary professionals, clinicians and researchers who work in the poultry sector

En el África oriental, en el gran valle del Rift, a la sombra del volcán Oldoinyo Lengai, vive un pueblo de guerreros y pastores: los masai. Las leyendas que aquí presentamos dan fe de la armonía en que vive este pueblo con la naturaleza y el resto de sus habitantes. Nos hablan de Enkai, la suprema divinidad presente en todas las cosas; de Ramat, la vaca que hablaba; de Simba, el león, rey de los animales… Dan testimonio asimismo de la difícil existencia de los masai.
Las leyendas, transmitidas de mayores a pequeños, ayudan a preservar los lazos que les unen a una cultura ancestral, amenazada por los turbulentos cambios en los modelos tradicionales de convivencia y por los desequilibrios ecológicos. Proceden de un remoto pasado, pero aún siguen ayudando a los masai a afrontar su futuro.

This student-friendly text illustrates how to balance design, materials, process selection, and economic and environmental analysis to optimize manufacturing processes for a given component. Following an overview of product design and development, the three-part book first discusses types of failure and ways to minimize it. Then it examines how material selection and manufacturing processes influence engineering design. The third part integrates technical and economic aspects of material selection. New and revised topics in this edition include new design considerations, environmental impact assessments, life cycle and recycling economics, and materials substitution.
