Predicting metabolisable energy in commercial rat diets: physiological fuel values may be misleading

Predicting metabolisable energy in commercial rat diets: physiological fuel values may be misleading.

Knowledge about metabolisable energy (ME) intake is crucial for various experimental settings in rodent studies. ME considers faecal and renal energy losses. In particular, faecal energy excretion can vary considerably between differentially composed diets. Thus determination of faecal energy losses, i.e. apparent energy digestibility, is the most important experimental approach to determine ME...

estimation of metabolisable energy equivalency value of natuzyme–p in deficient metabolisable energy diets

the objective followed in this study was to determine the amen equivalency of multienzyme natuzyme-p. one hundred and sixty male ross 308 broiler chicks were made use of in the experimentations. graded levels of amen, 2600, 2750, 2900, plus 3050 kcal/kg in the starter, and 2700, 2850, 3000, plus 3150 kcal/kg of the diet in the grower periods were used throughout the study. all the nutrients oth...

Confidence Intervals On Subsets May Be Misleading

Development of equations for predicting metabolisable energy concentrations in compound feeds for pigs.

In 2006 in Germany new recommendations for the supply of energy and nutrients to pigs were published, including a modification of the energy evaluation on the basis of metabolisable energy for pigs (MES). It was the objective of this meta-analysis to calculate equations that can be used for predicting MES in compound feeds for pigs on the basis of their nutrient concentrations. Data from digest...
