Predicting the metabolizable energy and metabolizability of gross energy of conventional feedstuffs for Muscovy duck using in vitro digestion method

Journal of Animal Science, 2023
AbstractIn total, two experiments were conducted to evaluate the effectiveness of an in vitro digestion method for predicting the metabolizable energy (ME) and metabolizability of gross energy (ME/GE) values using in vitro digestible energy (IVDE) and the digestibility of gross energy (IVDE/GE) content, respectively, of conventional feedstuffs for ...

A dynamic model of metabolizable energy utilization in growing and mature cattle. II. Metabolizable energy utilization for gain

Journal of Animal Science, 2003
Component models were developed to predict the net efficiency of ME utilization for gain in cattle and to predict daily gain using recovered energy as the input. These models were integrated into a single model to predict daily gain from ME available for gain.

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

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 ...

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.

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 ...

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)
