Book Description
The objectives of this study were to: 1) quantify mineral element concentrations of common forages by species and of different plant functional groups on sheep winter range, 2) evaluate producer supplementation strategies to determine estimated trace mineral shortfalls, 3) determine sheep diet composition during winter months utilizing fecal meta-barcoding to estimate dietary mineral intakes. Forage samples were collected from sheep winter ranges across 25 Wyoming sheep operations, and analyzed for Crude Protein (CP), Ca, P, K, Mg, S, Fe, Na, Zn, Mn, Cu, Mo, and Se concentrations. Questionnaire results reveal 80% of sheep producers supplement sheep on winter range, while only 40% provide a complete trace mineral mix and 35% provide white salt to ewes grazing winter range. Mineral element concentration results indicated a functional group effect in CP, Ca, P, K, Mg, S, Na, Zn, Mn, Cu, Mo, and Se concentrations between grass and shrub species (P

Book Description
This book is an up to date reference work covering all aspects of macro and trace element nutrition in farm livestock. Sufficient information is given on metabolism, functions and interactions to explain why needs, feeds and imbalances are not always easy to define or anticipate. The major emphasis is on the mineral nutrition of ruminant livestock since they are most likely to be affected by imbalances but where pigs and poultry are the more vulnerable, extensive coverage of the non-ruminant is given. This new edition of a highly successful text has been thoroughly revised and significantly expanded. Many chapters have been extensively updated and several chapters on new topics introduced. * Calcium, phosphorus, sodium and potassium are now treated separately * Over 40 new figures are presented, and extensive use made oftables to summarise important data * Chapters on trace elements have been drastically revised * Claims for enhanced availability for new chelated sources arecritically reviewed * Completely new chapters focus on: The unique need of the ruminant for elemental sulphur Occasionally beneficial elements and essentially toxic elements The improved conduct and interpretation of supplementation trials

Book Description
Proper formulation of diets for horses depends on adequate knowledge of their nutrient requirements. These requirements depend on the breed and age of the horse and whether it is exercising, pregnant, or lactating. A great deal of new information has been accumulated since the publication 17 years ago of the last edition of Nutrient Requirements of Horses. This new edition features a detailed review of scientific literature, summarizing all the latest information, and provides a new set of requirements based on revised data. Also included is updated information on the composition of feeds, feed additives, and other compounds routinely fed to horses. The effects of physiological factors, such as exercise, and environmental factors, such as temperature and humidity, are covered, as well. Nutrient Requirements of Horses also contains information on several nutritional and metabolic diseases that horses often have. Designed primarily as a reference, both practical and technical, Nutrient Requirements of Horses is intended to ensure that the diets of horses and other equids contain adequate amounts of nutrients and that the intakes of certain nutrients are not so excessive that they inhibit performance or impair health. This book is primarily intended for animal nutritionists, veterinarians, and other scientists; however, individual horse owners and managers will also find some of this material useful. Professors who teach graduate courses in animal nutrition will find Nutrient Requirements of Horses beneficial as a textbook.
