Dog Nutrient Requirements: New Knowledge
Veterinary Research Communications, 2005Dog nutrition was based on anecdotal knowledge from domestication until the beginning of last century. In 1943, McCay, in his book “Nutrition of the dog” quoted published studies and underlined that there was a real lack of information on this topic; more so than for other species.

Nutrient Requirements of Plants
Nature, 1968Nutrient requirement is a simple and useful concept when used in a qualitative sense, but it is much less satisfactory for quantitative comparisons among organisms. Some of the ambiguities and confusion in the present use of the concept are discussed, and more precise descriptions of the relations between nutrients and growth of plants are proposed.

Somatic Nutrient Requirements of Ruminants
Annual Review of Nutrition, 1986On the basis of existing information it is, perhaps, useful to propose tentative preliminary figures for somatic nutrient requirements (Table 2). Such a proposal may serve as a focus for research to clarify more precisely the somatic requirements for a given production function in a given species.

NUTRIENT REQUIREMENTS AT HIGH ALTITUDE
Clinics in Sports Medicine, 1999Travel to terrestrial altitudes greater than 2500 m, for more than 2 to 3 days, results in acute and long-term physiologic adaptations with the potential to profoundly affect the requirements for some nutrients. This article discusses the evidence for these increased requirements and makes recommendations regarding appropriate intakes at high altitude.

Specific Nutrient Requirements
2000Trace elements, like vitamins, are needed for vital cellular functions. Often they function as cofactors for enzymes. The quantity of trace elements required in the diet to maintain those functions is very small. Dietary intakes range from as little as 20 pg/d to about 20 mg/d. The requirements for macrominerals, such as calcium, phosphorus, magnesium,

Diarrhea and Nutrient Requirements
1983The high prevalence rates, particularly among young children in most developing countries, make the influence of diarrhea on nutritional requirements of major concern. The multiple mechanisms whereby diarrhea of infectious origin can affect dietary requirements for calories and protein are listed in Table I.

In order to maintain normal body function, humans must maintain a balance between energy requirements and caloric intake. Chemical factors not produced by the body such as minerals and vitamins must be obtained in order to utilize ingested calories for energy.

Nutrient Requirements of Premature Infants
2007Exact knowledge of the nutrient requirements of premature infants is critically important for the prevention of postnatal growth failure and for improved neurodevelopmental outcome. Methods whereby nutrient requirements can be estimated fall into two categories, factorial methods and empirical methods. Each have their advantages and disadvantages.
