Book excerpt: Dairy cattle replacement programs should provide management and nutrition that best supports the evolving needs of the developing heifer during all phases of rearing. The work described in this dissertation had two main objectives, i) to evaluate the supplementation of nutrients that could be limiting for dairy calves transitioning from the preruminant to the ruminant state, and ii) to quantify energy and protein requirements of the growing dairy animal. The first objective was addressed with two feeding trials evaluating what are considered limiting nutrients during the weaning phase. The first study tested the inclusion of different forms of methionine (Met), one rumen-protected and two different analogs (HMBTa and HMBi), in the calf starter. Calves fed the starter with HMBi consumed more feed postweaning and where heavier at the end of the study, but overall calves seemed not to be limited by Met. The second feeding trial assessed the effect of the combined supplementation of B-vitamins and choline on measures of performance and vitamin adequacy, and results suggested that dairy calves could obtain sufficient B-vitamins and choline from the diet and rumen synthesis to support growth rates over 1 kg/d. For the second objective, a database was constructed by merging eight comparative slaughter studies conducted on growing dairy cattle. Using this data set as input, a first analysis explored different aspects concerning nutritional energetics and generated new maintenance requirements coefficients, estimates of efficiency of ME utilization and predictive equations for energy retention for preruminant and ruminant dairy cattle. A variable efficiency of ME utilization for growth calculated as a function of feeding level offered the best prediction ability of energy retention. Finally, a subsequent analysis generated a system of equations to predict net requirements, true supply and efficiencies of use of N and AA for young preruminant dairy calves. Requirements were defined based on the supply of N and AA per Mcal from total ME and carbohydrate ME. A combined variable efficiency allowed the best prediction of N and AA balance on a net basis. Together both models improved the understanding on nutrient partitioning and enhanced the accuracy to predict nutrient requirements and utilization in growing dairy cattle.

Book excerpt: 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 excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management Addresses the urgent issue of sustainability in modern animal agriculture Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide

Available in PDF, EPUB and Kindle. Book excerpt: Nutrition and Lactation in the Dairy Cow is the proceedings of the 46th University of Nottingham Easter School in Agricultural Science. Said symposium was concerned with the significant advances in the field of nutrition and lactation in the dairy cow. The book is divided in five parts. Part I deals with the principles behind nutrition and lactation of cows. Part II discusses the cow’s nutrient interactions; responses to nutrients that yield protein and energy; and the influence of nutrient balance and milk yields. Part III tackles the efficiency of energy utilization in cows and its relation to milk production. Part IV talks about food intake of cows and the factors that affect it, while Part V deals with the different feeding systems for cows. The text is recommended for those involved in raising cows and dairy production, especially those who would like to know more and make studies about the relationship of nutrition and lactation of cows.

Available in PDF, EPUB and Kindle. Book excerpt: From birth to first calving, the replacement heifer undergoes tremendous changes anatomically as well as in feeding and management practices. The calf changes from being a pseudo-monogastric to a full ruminant within a period of two months. During the same period, the calf is fed colostrum, milk, or milk replacer, and starter with or without hay. Notably, the lifetime milk production and health of a dairy cow is highly dependent on early life nutrition and management of the calf and, subsequently, the heifer. Hence, animal scientists continue to investigate critical areas such as colostrum feeding, the level of liquid feeding, gut microbial succession, energy and protein levels, housing, health management, and their interactions with the animal in an effort to help dairy producers raise successful and sustainable dairy enterprises.

Book excerpt: Nutrient Requirements of Domesticated Ruminants draws on the most up-to-date research on the energy, protein, mineral, vitamin and water requirements of beef and dairy cattle, sheep and goats. It defines the responses of animals, in weight change, milk production and wool growth, to quantitative and qualitative changes in their feed supply. It has particular application to grazing animals. Factors affecting the intake of feed are taken into account and recommendations are given according to the production systems being used; for instance, the feed intake of a grazing animal is affected by a larger number of variables than a housed animal. Examples of the estimation of the energy and nutrients required for the different production systems are given, as well as the production expected from predicted feed intakes. The interactions between the grazing animal, the pasture and any supplementary feeds are complex, involving herbage availability, diet selection and substitution. To facilitate the application of these recommendations to particular grazing situations, readers are directed to decision support tools and spreadsheet programs. Nutrient Requirements of Domesticated Ruminants is based on the benchmark publication, Feeding Standards for Australian Livestock: Ruminants, published in 1990 by CSIRO PUBLISHING on behalf of the Standing Committee on Agriculture. It provides comprehensive and useful information for graziers, livestock advisors, veterinarians, feed manufacturers and animal nutrition researchers. The recommendations described are equally applicable to animals in feedlots or drought yards.

Available in PDF, EPUB and Kindle. Book excerpt: Animal Life-Cycle Feeding and Nutrition reviews developments in feeding and nutrition throughout an animal's life cycle and covers a wide range of topics, from utilization of nutrients such as carbohydrates and proteins to nutrient digestion by ruminants, swine, poultry, and horses. Feedstuffs such as pasture and harvested forages, protein concentrates, and cereal and sorghum grains are also discussed. Comprised of 21 chapters, this book begins with a discussion on nutrients and their utilization, including carbohydrates, lipids, proteins, and minerals and vitamins. Nutrient digestion by ruminants, swine, poultry, and horses are then compared and feedstuffs for livestock are evaluated. The next section deals with feedstuffs such as pasture and harvested forages, protein concentrates, and cereal and sorghum grains, together with molasses, manure, and other miscellaneous feed ingredients. The remaining chapters explore the effect of processing on the nutrient value of feedstuffs; balancing of rations; and feeding of animals including swine, beef and dairy cattle, poultry, sheep, horses, dogs, and goats. This monograph is designed for students of animal sciences, for veterinary students as well as doctors of veterinary medicine, and for practitioners of livestock feeding.
