Provides nutrient recommendations based on physical activity and stage in life, major factors that influence nutrient needs. This report also looks at how nutrients are metabolized in the bodies of dogs and cats, indications of nutrient deficiency, and diseases related to poor nutrition.

Proper formulation of diets for horses depends on adequate knowledge of their nutrient requirements. This book covers information on the composition of feeds, feed additives, and other compounds routinely fed to horses. It also contains information on several nutritional and metabolic diseases that horses often have.

Provides an evaluation of the scientific literature on the nutrient requirements of small ruminants in all stages of life. This book addresses the effects of the environment, feed additives, and metabolism modifiers on nutrient requirements. It is suitable for animal nutritionists, veterinarians, and other scientists.

Reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States.

Increased agricultural productivity is a major stepping stone on the path out of poverty in sub-Saharan Africa and South Asia, but farmers there face tremendous challenges improving production.
