The Transport of Metabolizable Substances into the Living Brain

1976
Much knowledge about the many enzymic processes by which the cerebral cells can change one substance into another has been derived from in vitro work. However, such in vitro experiments do not tell us the quantities of the various nutrient substances that the living brain needs to obtain from the blood in order to function normally. Nor do they tell us

Energy and metabolizable protein supply

2011
Several systems are used to measure energy (Van Es, 1978; Moller et al., 1983; INRA, 1989; NRC, 1989; AFRC, 1993) and metabolizable protein (MP) (Madsen, 1985; NRC, 1985; Verite et al., 1987; AFRC, 1992; Tamminga et al., 1994) supplies in cattle. Feed evaluation for cattle is in continues development and several new systems have been proposed (Sniffen ...

Metabolizable Energy in Poultry Nutrition

BioScience, 1980
Modern commercial poultry production, like other industrial enterprises, demands control of cost inputs. The major cost is feed, the input of which is determined by biological, managerial, and economic constraints. Under conditions of ad libitum feeding, birds tend to eat to satisfy their energy requirements, which vary with body size, activity, rate ...

Expressing the Variability in Results of Metabolizable Energy Assays

The Journal of Nutrition, 1986
In estimating the metabolizable energy of a food or feedstuff (MEf), the ME of a reference diet (MEr, containing glucose monohydrate) and the ME of a test (MEt, containing the feedstuff substituted for glucose) are determined from a feeding trial: MEf = MEglucose -1/P (MEr - MEt) where P is a proportion of substitution. Traditionally, MEr has been used

Estimation of the metabolizable energy equivalence of dietary proteins

European Journal of Nutrition, 2006
Protein contributes significantly to the human daily energy budget. The high diversity in composition, digestibility and dietary proportion complicates the estimation of its actual energy contribution. In practical terms we continue using the energy equivalents estimated by Atwater.

Contribution of fiber and resistant starch to metabolizable energy

The American Journal of Clinical Nutrition, 1995
Recommendations made to increase complex carbohydrate and fiber intake in the United States may result in energy loss from increased fecal losses of starch, protein, and fat. The type of fiber or starch and the amount consumed affect digestion of the carbohydrate and interactions with other nutrients.

An Assessment of Quick Bioassays for Determining the True Metabolizable Energy and Apparent Metabolizable Energy of Poultry Feedstuffs

World's Poultry Science Journal, 1981
There are two methods in use currently for the rapid hiolopical determination of metabolizable energy content of feedstuffs for poultry. One method gives a 'true' metabolizable energy (TME) value (Sibhald 1976a), and the other an 'apparent' metabolizable energy (ME) value (Farrell 1978a, 1980)
