This book addresses various aspects of in vitro digestibility: • Application of meta-analyses and machine learning methods to predict methane production; • Methane production of sainfoin and alfalfa; • In vitro evaluation of different dietary methane mitigation strategies; • Rumen methanogenesis, rumen fermentation, and microbial community response; • The role of condensed tannins in the in vitro rumen fermentation kinetics; • Fermentation pattern of several carbohydrate sources; • Additive, synergistic, or antagonistic effects of plant extracts; • In vitro rumen degradation and fermentation characteristics of silage and hay; • In vitro digestibility, in situ degradability, and rumen fermentation of camelina co-products; • Ruminal fermentation parameters and microbial matters to odd- and branched-chain fatty acids; • Comparison of fecal versus rumen inocula for the estimation of NDF digestibility; • Rumen inoculum collected from cows at slaughter or from a continuous fermenter; • Seaweeds as ingredients of ruminant diets; • Rumen in vitro fermentation and in situ degradation kinetics of forage Brassica crops; • In vitro digestibility and rumen degradability of vetch varieties; • Intestinal digestibility in vitro of Vicia sativa varieties; • Ruminal in vitro protein degradation and apparent digestibility of Pisum sativum; • In vitro digestibility studies using equine fecal inoculum; • Effects of gas production recording system and pig fecal inoculum volume on kinetics; • In vitro methods of assessing protein quality for poultry; and • In vitro techniques using the DaisyII incubator.

Feedstuff Evaluation contains the proceedings of the 50th University of Nottingham Easter School in Agricultural Sciences, held at Sutton Bonington in July 1989. The book presents papers discussing a wide range of topics on the accurate evaluation of feedstuffs for livestock. Initially, systems of expressing the nutritive value of feeds are considered. Modifications to feeding value as influenced by animal factors including intake and palatability are discussed. Specific dietary ingredients, being plant polysaccharides, fats, minerals and vitamins are detailed. Prediction of the nutritive value of compound feeds and individual feeds through classical wet chemistry and the more recent NIR is assuming considerable importance in the rapid evaluation of diets. Associated with these developments is an appreciation of the relevance of both inter- and intra-laboratory variation in determinations. Finally, the need to collate information into an interactive data-base is being actively pursued. It is evident that safety of animal feeds is becoming an increasingly topical issue and the last session considered the relevance of naturally-occurring toxic factors, residues, mycotoxins and, finally, animal pathogens. Veterinarians, farmers, farm administrators, and those involved in every aspect of nutrient supply to animals will find the compendium very insightful and informative.

Current pressures to maximise the use of forages in ruminant diets have renewed interest in fast, inexpensive methods for the estimation of their nutritional value. As a result, a wide variety of biological and physiochemical procedures have recently been investigated for this purpose.This book is the single definitive reference volume on the current status of research in this areaCovers all forages eaten by ruminant animals

The primary purpose of each of the subsequent chapters of this book is to promulgate quantitative approaches concerned with elucidating mechanisms in a particular area of the nutrition of ruminants, pigs, poultry, fish or pets. Given the diverse scientific backgrounds of the contributors of each chapter (the chapters in the book are arranged according to subject area), the imposition of a rigid format for presenting mathematical material has been eschewed, though basic mathematical conventions are adhered to.
