Digestible and metabolizable energy of crude glycerol for growing pigs.
The apparent DE and ME values of crude glycerol for growing pigs were determined in 5 experiments using crude glycerol (86.95% glycerol) from a biodiesel production facility, which used soybean oil as the initial feedstock. Dietary treatments were 0, 5, or 10% glycerol addition to basal diets in Exp. 1; 0, 5, 10, or 20% glycerol addition to basal diets in Exp. 2; and 0 and 10% crude glycerol ad...
متن کاملDigestible indispensable amino acid score and digestible amino acids in eight cereal grains.
To determine values for the digestible indispensable amino acid score (DIAAS), it is recommended that ileal amino acid (AA) digestibility values obtained in growing pigs are used to characterise protein quality in different foods. Therefore, an experiment was conducted to determine the standardised ileal digestibility (SID) of AA in eight cereal grains (yellow dent maize, Nutridense maize, dehu...
متن کاملPredicting microbial protein synthesis in beef cattle: relationship to intakes of total digestible nutrients and crude protein.
Prediction of microbial CP (MCP) synthesis in the rumen is an integral part of the MP system. For the NRC beef model, MCP is calculated as 0.13 multiplied by TDN intake (TDNI), with adjustment for physically effective NDF (peNDF) concentrations less than 20%. Despite its application for nearly 2 decades, MCP predictions using this approach have not been extensively evaluated. We assembled a dat...
متن کاملProtein digestibility-corrected amino acid scores and digestible indispensable amino acid scores differentially describe protein quality in growing male rats.
BACKGROUND The FAO has recommended replacing the protein digestibility-corrected amino acid score (PDCAAS) with the digestible indispensable amino acid score (DIAAS). OBJECTIVE The objective of this study was to compare aspects underlying the calculation of the DIAAS and PDCAAS, including 1) fecal digestibility vs. ileal digestibility, 2) using a single nitrogen digestibility value for all am...
متن کاملComparison of the nutritive value for laying hens of diets containing azolla (Azolla pinnata) based on formulation using digestible protein and digestible amino acid versus total protein and total amino acid
Azolla (Azolla pinnata) was assessed for nutrient content and feeding value in laying hen diets. Proximate analysis, together with the estimates of digestible protein, ADF, NDF and metabolizable energy indicated that it was a fair source of plant protein (285.4 g kgÿ1) with a digestible protein value of 219.8 g kgÿ1 and a metabolizable energy value of 7.59 MJ kgÿ1 (906 g kgÿ1 DM). The feeding v...
