Book Description
"The need to preserve farm animal diversity is increasingly urgent, says the author of this definitive book on endangered breeds of livestock and poultry. Farmyard animals may hold critical keys for our survival, Jan Dohner warns, and with each extinction, genetic traits of potentially vital importance to our agricultural future or to medical progress are forever lost."--BOOK JACKET.

Book Description
Mason's World Dictionary of Livestock Breeds, Types and Varieties, now in its sixth edition, has a long history as a reliable and authoritative source of key livestock breed information. Intended as a list of livestock names and synonyms for breeds, groups, types and varieties worldwide, the dictionary aims to include all names found in the literature, 'defining' each breed or type with a brief indication of identifying characteristics, uses and source of origin.

Book Description
This book covers the most significant breeds of cattle, goats, sheep, and swine - from the common Guernsey cow to the near-extinct Guinea hog. For each breed, Ekarius provides full-colour photographs, a brief history, and details about the breed's unique qualities and quirks. Readers will enjoy reading about major breeds such as the iconic Holstein cow, and Icelandic sheep, as well as hundreds of lesser-known varieties, like the long-legged, ginger-coloured Tamworth pig; the lilac-spotted Jacob Sheep; the deer like San Clemente goat; and the powerful, droopy-eared Guzerat cow.

Book Description
Seventy breeds of livestock in America are rare. What would happen if these breeds of asses, cattle, goats, horses, pigs, and sheep were to become extinct? Agriculture will have lost the genetic resources necessary to adapt to changes in the environment and human needs. A link in the Earth's biodiversity will have been broken. And people in the future will be deprived of the flash of a Spanish Mustang in the misty morning, the rich pallette of colors in a flock of Navajo-Churro sheep, and the gentle lowing of a Cracker cow to her newborn calf. If rare breeds are lost, the animal kingdom and the human experience will be diminished forever. This book shows what is at stake -- the breed diversity that is our natural heritage and cultural inheritance. Learn how rare breeds are being protected and how you can become a part of this unique conservation effort.

Book Description
Most of the future increase in livestock production is expected to occur in the tropical and subtropical regions of the world. Cattle are the most numerous of the ruminant species in the tropics and provide the largest quantity of animal food products. More than one-third of the world's cattle are found in the tropics. Disease is the major factor which prohibits full utilization of these regions for cattle production. Various infectious and transmissible viral, rick ettsial, bacterial, and particularly protozoan and helminthic diseases, are widespread in the tropics and exert a heavy toll on the existing cattle industry there. This uncontrolled disease situation also discourages investment in cattle industries by private and government sectors. In Africa alone, it is estimated that 125 million head of cattle could be accommodated in the tropical rainbelt if the disease and other animal husbandry factors could be resolved. The potential of efficient cattle production under more favorable conditions prompted various international agencies to establish a multi million dollar International Laboratory for Research in Animal Diseases (ILRAD) in Nairobi, Kenya, Africa. In South America, principal sites for raising cattle are shifting to the savannah lands because the more fertile soils are being used for crop produc tion, however, in the savannahs also, disease remains the most powerful deterrent in implementing the cattle industry.

Book Description
The production of animal feed increasingly relies on the global acquisition of feed material, increasing the risk of chemical and microbiological contaminants being transferred into food-producing animals. Animal feed contamination provides a comprehensive overview of recent research into animal feed contaminants and their negative effects on both animal and human health.Part one focuses on the contamination of feeds and fodder by microorganisms and animal by-products. Analysis of contamination by persistent organic pollutants and toxic metals follows in part two, before the problem of natural toxins is considered in part three. Veterinary medicinal products as contaminants are explored in part four, along with a discussion of the use of antimicrobials in animal feed. Part five goes on to highlight the risk from emerging technologies. Finally, part six explores feed safety and quality management by considering the safe supply and management of animal feed, the process of sampling for contaminant analysis, and the GMP+ feed safety assurance scheme.With its distinguished editor and international team of expert contributors, Animal feed contamination is an indispensable reference work for all those responsible for food safety control in the food and feed industries, as well as a key source for researchers in this area. - Provides a comprehensive review of research into animal feed contaminants and their negative effects on both animal and human health - Examines the contamination of feeds and fodder by microorganisms and animal by-products - Analyses contamination by persistant organic pollutants, toxic metals and natural toxins

Book Description
This dictionary covers cattle, sheep, pigs, goats, horses, donkeys and buffalo. It includes all names which have been applied to interbreeding groups of these species whether they are called breeds, sub-breeds, types, varieties, strains or lines. The region or country of origin of each group is given and this is followed by a very brief description of the breed in terms of products, color, and major morphological features. There is a note on the history of the breed and the dates of formation of breed societies and herdbooks. Synonyms for its name are listed as well as the present conservation status. This new edition includes approximately 9,000 entries, of which 5,000 are main entries and 4,000 are cross references. This represents an increase on the third edition of 18% for main entries and 13% for cross references. The highest proportion of new breed entries are in the horse and pig chapters. Furthermore some 2,300 entries (30%) have been amended. These include 400 major changes, such as new name, extinction, or the extension of a bare name to a complete entry. They also include 1,900 entries with minor changes, for example new breed society, new synonyms, additions to distribution or description, changes in spelling or of conservation status. China features strongly in all additions and amendments. In addition to these changes references to USSR, Yugoslavia and Czechoslovakia have been corrected in accordance with the current country names. Overall the book continues to represent the standard reference work for all concerned with domestic livestock, particularly those involved in animal breeding and genetics.
