Du and Peiqiang Yu Index 247 PREFACE This new book presents topical research in the study of animal feed, including conventional and novel feed research programs; veterinary drug use and environmental safety; microbiological safety and quality of animal feeding stuffs; the effects of selected feed compounds and feed additives on the gastrointestinal tract functions in farm animals and a risk analysis of compound feed contamination. Chapter 1 – Brown algae have been a component for ruminant diets in coastal areas for millennia. Recently, there has been a renewed interest in using brown algae in ruminant diets with an emphasis on the benefits of this feed to both animal and environmental health. Laboratory and animal studies have shown that brown algae or its extracts can reduce the shedding of bacterial pathogens, serve as an antioxidant, enhance immune function and moderate the impact of toxins on ruminants. Although the agents responsible for these biological responses remain to be fully elucidated, bioactive compounds such as phlorotannins and fucodians are almost certainly responsible for some of these responses. This chapter reviews recent research that has defined the effects of brown algae and their role in animal health, rumen microbiology, nutrient digestion, metabolism and overall animal productivity. Chapter 2 – Animal feed is the largest single cost (~60 to 75%) of production facing livestock feeding operations not only in Canada but also in the world. As Ministry of Agriculture Strategic Research Chair of Feed Research and Development, the authors feed research programs aim to develop new, high value feeds and new feeding applications and increase feed and livestock production efficiencies through improved livestock product quality reduce environmental impact and support sustainable animal production. Feed advancement is based on a new level of understanding and analytical information on feeds including the effect of intrinsic structures of feeds in relation to feed quality, digestive behavior and nutrient utilization. In this article, recently obtained information on their feed and nutrition research and methodology development is reviewed. The emphasis of this review is on both conventional and novel feed research programs and progress made in our research team, which are include: (a) Foreign gene-transformation to feeds to increase nutrient availability, (b) Feed heating processing to manipulate the nutrient digestive behaviour; (c) Fractionation of a feed to extract increased value from the feedstuffs, improve the competitive position of the livestock industry, and to increase economic returns. This article also reported that progress on traditional and non-conventional feed research methodology, including (a) Novel synchrotron-based bioanalytical techniques to study feed structures at cellular and molecular levels in relation to nutrient availability as well as viii Sarah R. Borgearo synchrotron-based molecular nutrition research and (b) Modeling nutrient supply to more accurately accounts for digestive processes in ruminants on a quantitative basis. The information described in this paper gives better insight in feed research progress and update. Chapter 3 – Presently, the aspects related with human nutrition are of significant importance, focusing the attention of scientists and policymakers regarding the safety of food supplies. Furthermore, the world‘s continuously growing population and the correlated decrease of natural resources have led to the steep increase of animal farming, especially aquaculture. To assure farmed animal‘s health the resort to chemicals and veterinary drugs is frequently taken. This practice in animal production is well described, whether for prophylaxis or therapeutical needs, which dictated the implementation of regulations regarding a responsible use of drugs and chemicals, to reduce the hazards (defined as ―a biological, chemical or physical agent in, or condition of,
