Book Description
Three trials were conducted to assess the influence of the barley silage particles as a source of effective fiber in total mixed rations for ruminants. Trial one determined the effective fiber characteristics of barley silage at different theoretical cut length; short barley silage (SBS) = 4.68 mm and long barley silage (LBS) = 18.75 mm in a replicated switch back design using six steers fitted with rumen fistulae to measure rumen fermentation patterns, kinetics, digestibility of cell wall constituents. In the second trial, four steers fitted with rumen fistulae in a 4 x 4 Latin square design were used to study the effect of barley silage particle size and concentrate level on the above variables. The third trial used eight multiparous lactating dairy cows in a replicated 4 x 4 Latin squire design to determined the effect of barley silage particle size and concentrate level on eating behavior, milk production and composition. In the first trial, feeding SBS increased DMI and total tract digestibility of DM, NDF and ADF compared with LBS. Mean ruminal pH was lower for steers fed SBS than those fed LBS but pH range was higher (P

Book Description
Globally, dairy and beef production has become an extremely competitive industry. While the world milk production is predicted to grow significantly by 2020 with the emergence of new consumers in developing countries, milk and meat production in the more establish markets now has to fulfil new societal needs beside the simple product supply: animal health, food safety, and production environmental impact are some of them. At the same time, the recent extreme increase in feed costs emphasizes again the key role of rumen and gut efficiency management in production economics. All these new thematic topics are central to the proper management of ruminant digestive process. Producers must endeavour to seek new technologies to improve production efficiency, animal health and production costs while keeping in mind the environmental impact these changes make. ‘Gut efficiency; the key ingredient in ruminant production’ brings together some of the world’s leading authorities in the field of ruminant nutrition and production. It considers the importance of digestive health in performance achievement together with novel strategies to manage it. It is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences.

Book Description
In a changing climate, livestock production is expected to exhibit dual roles of mitigation and adaptation in order to meet the challenge of food security. This book approaches the issues of livestock production and climate change through three sections: I. Livestock production, II. Climate change and, III. Enteric methane amelioration. Section I addresses issues of feed quality and availability, abiotic stress (heat and nutritional) and strategies for alleviation, livestock generated nitrogen and phosphorus pollution, and approaches for harnessing the complex gut microbial diversity. Section II discusses the effects of climate change on livestock diversity, farm animal reproduction, impact of meat production on climate change, and emphasising the role of indigenous livestock in climatic change to sustain production. Section III deals with the most recent approaches to amelioration of livestock methane such as breeding for low methane emissions, reductive acetogenesis, immunization/vaccine-based concepts and archaea phage therapy.

Book Description
NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. The first is concerned with information on feed characteristics, feed analysis and feed digestion methods. The second section describes the digestion and metabolism in the gastrointestinal tract and the supply and requirement of energy and metabolizable amino acids. The third section considers the prediction of feed intake and physical structure of the diet. The fourth section focuses on model evaluation and the final section provides information on the IT solutions and feed ration formulation by a non-linear economical optimization procedure. This book will be of significant interest to researchers, students and advisors of cattle nutrition and feed evaluation.
