In facing ever more limited resources and changing market conditions and in the attempt to enhance productivity for strengthening livelihoods, many technologies have been used to improve feed use and animal performance at the faro level. A particularly successful example, in terms of both geographic range of use and relative simplicity in formulation and preparation, is the urea-molasses multi-nutrient block technology. This publication provides a comprehensive overview of development and use of the block technology in countries around the world and it might be of great practical value to extension workers, students, researchers and those thinking of using such feed supplementation technology or of starting commercial production.

In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparationâ€"including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.

This book discusses knowledge-based sustainable agro-ecological and natural resource management systems and best practices for sustained agricultural productivity and ecosystem resilience for better livelihoods under a changing climate. With a focus on agriculture in Africa, the book assesses innovative technologies for use on smallholder farms, and addresses some of the key Sustainable Development Goals to guide innovative responses and enhanced adaptation methods for coping with climate change. Contributions are based on 'Capacity Building for Managing Climate Change in Malawi' (CABMACC), a five-year program with an overall goal to improve livelihoods and food security through innovative responses and enhanced capacity of adaptation to climate change. Readers will discover more about sustainable crop production, climate smart agriculture, on-farm energy supply from biogas and the potential of soil carbon sequestration in crop-livestock systems.

Widespread in North American forest regions including the Rocky Mountains, the Boreal Owl (Aegolius funereus) was once the most numerous predatory bird in Eurasian boreal forests. Synthesising the results of unique long-term studies of Boreal Owls, this book explores hunting modes, habitats and foods, prey interactions, mating and parental care, reproduction, dispersal, survival and mortality, population regulation and conservation in boreal forests. Providing a detailed introduction to the species, the authors study the complex interactions of Boreal Owls with their prey species. They examine the inter-sexual tug-of-war over parental care, and the behavioural and demographic adaptations to environmental conditions that predictably and markedly fluctuate both seasonally and multi-annually. They also question whether Boreal Owls are able to time their reproductive effort to maximise lifetime reproductive success. Discussing the effect of modern forestry practices on owl populations, the book also examines how Boreal Owls could be managed to sustain viable populations.

Handbook of Fertility: Nutrition, Diet, Lifestyle and Reproductive Health focuses on the ways in which food, dietary supplements, and toxic agents, including alcohol and nicotine affect the reproductive health of both women and men. Researchers in nutrition, diet, epidemiology, and endocrinology will find this comprehensive resource invaluable in their long-term goal of understanding and improving reproductive health. This book brings together a broad range of experts researching the different aspects of foods and dietary supplements that promote or detract from reproductive health. Section One contains several overview chapters on fertility, how it is assessed, and how it can be affected by different metabolic states, nutritional habits, dietary supplements, the action of antioxidants, and lifestyle choices. Sections Two and Three consider how male and female fertility are affected by obesity, metabolic syndrome, hormonal imbalance, and even bariatric surgery. Section Four explores the ways diet, nutrition, and lifestyle support or retard the success of in vitro fertilization, while Section Five explores how alcohol and other drugs of abuse lower fertility in both women and men. - Explores how alcohol, nicotine, and other drugs of abuse disrupt and impair reproductive health - Reviews studies of common conditions such as obesity and metabolic syndrome and their effect on fertility and reproductive health - Investigates the components of foods and dietary supplements, in particular oxidative stress and antioxidants - Presents the nutritional effects of foods and dietary supplements and their benefits and risks relating to reproductive health
