Ensiling is a technique that is used to store food, mainly vegetable crops, to feed the herd when the forage supply from the pastures is not enough to maintain the productive performance of the ruminant animals. However, silage can also be used as substrate for biogas production and other different purposes. In the past years, we have seen many advances in the knowledge about silage production utilization, and this book is a compilation and discussion of the outstanding scientific research activities concerning actually the most recent advances and technologies that have been studied about silage and future demands. It is directed to a broad public of readers - farmers, academics, students, or anyone just curious or interested in the subject.
This work--the first of its kind in more than sixty years--covers polo in Argentina, from its beginnings in the 1870s to the summer of 2013. The history of the early pioneers is constructed with data not previously published, gathered from contemporary sources. International competitions are covered and include the Olympic Games, the Cup of the Americas and the World Championships. Particular attention is given to the major clubs, the Argentine and Hurlingham Open Championships, and the National Handicap Tournament. Several of the elite players merit individual or family mini-biographies. Myths in Argentine polo are also debunked, based upon careful analysis of contemporary sources. Travels abroad by Argentine teams are fully described as are the foreign teams that competed in Argentina. The work is enhanced by the author's personal observation of significant events and friendship with many of the participants.

While the pandemic lasts, Latin America and the Caribbean (LAC) will go through a tunnel full of uncertainty. It is not known especially how long it is: how long until therapies or a vaccine emerge, or until best practices are known to control the pandemic to live with a virus of unknown lethality. This note describes policy options on how countries can expand their possibilities to meet the economic challenges of the crisis, with an emphasis on growth and equity. These options are based on the assumption that the fiscal situation of the region and its access to sovereign credit markets are much more restricted than in previous crises, which forces to think about policy reforms beyond fiscal...
Designed to cover techniques for analysis of data in the animal sciences, this popular textbook provides an overview of the basic principles of statistics enabling the subsequent applications to be carried out with familiarity and understanding. Each chapter begins by introducing a problem with practical questions, followed by a brief theoretical background. Most topics are followed up with numerical examples to illustrate the methods described using data-sets from animal sciences and related fields. The same examples are then solved using the SAS software package. Written primarily for students and researchers in animal sciences, the text is also useful for those studying agricultural, biological, and veterinary sciences.
