Foreword

Silage is an important source of forage for ruminant animals, especially beef and dairy cattle, in many areas of the world. In the USA, nearly 10% of the corn crop along with sizeable hectarages of legume and grass forages, sorghum, and small grains are harvested as silage. In Europe, half or more of the corn hectares are used for silage. When the information presented in this publication is used to implement a harvesting, storage, and feeding system, silage will provide a high-energy, palatable, nutritious feed that utilizes the entire above-ground biomass production of the crop.

The process of ensiling results in a harvesting system that preserves high-quality forage crops for long period of time, as well as allows producers to salvage frost-or drought-damaged crops and convert them into a useable feedstock. The ensiling process often results in forage of higher quality than other harvesting techniques, especially in areas where climatic factors limit the ability to dry the crop to a storable moisture content before another precipitation event. Such climatic limitations often do not permit the consistent production of high-quality forage crops.

The authors of this publication have summarized hundreds of research articles that provide a sound scientific explanation of the technical aspects of silage production. Students, farmers, and scientists will find this book to be a useful reference.

Appreciation is expressed to the Editors, the ASA-CSSA-SSSA Headquarters staff, authors, the organizing committee, and reviewers for the countless hours they have contributed to the production of this book.

Preface

Production of silage, defined as the acidic, fermented, stored products from an agricultural crop, is a practice tracing its roots back some 3000 years to the ancient Egyptians and Greeks. The rapid increase in application of this technology, however, has occurred mostly since mechanization of agriculture beginning in the 1940s. Advances in silo construction, harvesting technology, and improved understanding of the biology and chemistry of ensiling have advanced the rate of adoption of silage production. Silage production is now well established in Europe and North America and is gaining popularity in other areas, including tropical regions. It is especially important where the probability of precipitation limits the opportunity for dependable hay production. Silage production requires either no wilting of the crop at harvest, as in the case of com or sorghum, or less wilting than for hay, as in the case of high-moisture forage crops such as alfalfa, perennial forage grasses, or small grains.

This monograph contains 19 chapters and serves as an in-depth reference for all aspects of silage production and feeding. It is unique in its broad coverage of silage production, including in-depth discussions of microbiology, biochemistry, assessing quality, preharvest plant factors, postharvest factors, use of silage additives to modify fermentation, harvesting, storage, feeding, whole-farm management, and numerous other factors that influence the quantity and quality of silage. Individual chapters are devoted to the production, preservation, and feeding of specific crops important in silage production. The final chapter integrates information from the earlier chapters into practical applications for forage production, storage, and feeding, as well as solutions to frequently encountered silage storage and feeding problems.

The monograph is worldwide in scope, with application to most areas where silage production and use are important. The intended audience is advanced undergraduate and graduate students, scientists, skilled farm and livestock producers and their advisors, and allied industrial representatives. The authors are internationally recognized experts, carefully selected for their knowledge and understanding of various aspects of crop and grain ensiling. Multiple authors were chosen for nearly all chapters, and their combined expertise has produced a monograph that greatly enhances our understanding of silage production. It fills the void for a current, comprehensive volume on all aspects of silage production, storage, and feeding.

We express appreciation to the authors whose dedication and work made this monograph possible. We also thank the many scientists who served as reviewers for the chapters. In addition, we are grateful to Lisa Al-Amoodi, who served as the managing editor, and to all of the headquarters staff at Madison, WI, for helping with the publication.
