Book Description
Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.

Book Description
The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded

Book Description
As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

Book Description
Nitrate poisoning of livestock caused by an excessive intake of nitrate from plants or water has been recognized for over 70 years . The symptoms of nitrate poisoning in livestock include rapid, shallow breathing, wobbly gait, decreased milk production, abortion and death. Nitrate is the major nutrient form in which nitrogen is absorbed by plants and in the great majority of cases, it is assimilated so rapidly that its concentration rarely rises above 0.03%. When conditions occur which retard growth of the plant, the nitrate content may rise to 5% or higher on the dry matter basis. Water containing nitrate has also been responsible for poisoning cattle and sheep. The native muck soils of Florida contain high levels of molybdenum and nitrate but very low levels of copper. Molybdenum toxicity of cattle grazing forages grown on these soils has been recognized and its alleviation by supplementation of cattle with copper has been established. Feed-lot trials with young dairy bull calves fed levels of molybdenum as high as 100 and 200 ppm mixed in their rations for 22 weeks had no ill effects. This indicated that molybdenum toxicity was more complex than was generally recognized. Nitrate reductase contains molybdenum, and copper has a similar relation to nitrite reductase. With high concentrations of nitrate in the forages grown on the muck soils of Florida, the rate of nitrate reduction to nitrite in the rumen may be related to the concentration of molybdenum present. The nitrite may accumulate due to lack of copper and thereby increase the hazard of a moderate concentration of nitrate. The nitrite, upon absorption into the blood, may have contributed to the molybdenosis symptoms reported in cattle on these muck soils by oxidizing the iron of hemoglobin to the ferric state forming methemoglobin. The purpose of the present study was to determine if different levels of molybdenum and copper were practical factors in the rate at which nitrate in forage is reduced in the rumen of cattle and sheep. Cattle and sheep were fed forages especially grown to contain high nitrate and varying levels of molybdenum and copper. The reduction of nitrate with varying concentrations of molybdenum and copper was also studied in vitro.

Book Description
Nitrite and Nitrate in Human Health and Disease delivers a comprehensive review of nitrite and nitrate biology, from basic biochemistry to the complex physiology and metabolism of these two naturally occurring molecules in the human body. Well-organized and well referenced chapters cover the rich history of nitrite and nitrate, sources of exposure, and the physiological effects when consumed through foods containing nitrite and nitrate. The chapters are written by leading experts, all of whom share their research and perspectives in order to help define the context for benefits vs. any potential risks associated with nitrite and nitrate use, either through dietary ingestion or therapeutic dosing. This diverse collection of authors includes vascular biologists, physiologists, physicians, epidemiologists, cancer biologists, registered dieticians, chemists, and public health experts from five countries in both academia and government. Nitrite and Nitrate in Human Health and Disease provides a balanced view of nitric oxide biochemistry, and nitrite and nitrate biochemistry in physiology and in the food sciences.
