Driver distraction is a leading cause of crashes. The introduction of in-vehicle technology in the last decades has added support to the driving task. However, in-vehicle technologies and handheld electronic devices may also be a threat to driver safety due to information overload and distraction. Adaptive in-vehicle information systems may be a...

Het zijn spannende tijden nu de economie in een crisis is geraakt. Het kabinet is inmiddels na overleg met de sociale partners met een flink pakket aan maatregelen gekomen. Veel van deze maatregelen hebben betrekking op het arbeidsmarktbeleid. Dat is een goede zaak, want benutting van kansen op de arbeidsmarkt en stimulering van de...

The paper summarizes and evaluates data on estimates for the amount and amino acid (AA) composition of basal endogenous crude protein (CP) at the terminal ileum of pigs derived from 33 ileal digestibility studies with pigs (30-100 kg BW). Different methods and approaches are used to obtain these estimates: (A) the N-free diet method (16 studies)...

A procedure for the ileostomisation of adult roosters has been described with the use of flexible silicon cannulas. Apparent ileal digestibility coefficients for dry matter (aDC DM), crude protein (aDC CP) and amino acids (aDC AA) in six diets, formulated with maize, wheat gluten, faba beans, lupins, soybean meal and casein as the main protein...

The objective of the present study was to determine the effects of the combination of a lactoperoxidase system (LP-s) and lactoferrin (LF) added to a milk replacer diet on severity of diarrhoea, the morphology of the small intestinal mucosa, and the microbiology of digesta and faeces in young calves, in comparison with a control diet. The...

Effects of the use of three different soyabean products (soya concentrate and two different soyabean meals), peas or rapeseed hulls in the diet on the apparent ileal digestibility of CP (N x 6.25) and recovery of ileal endogenous nitrogen (N) in weanling pigs were investigated. Ileal endogenous N was measured using the 15N-isotope dilution...

An experiment was carried out to determine the flux of amino acids across the portal vein-drained tissue into and out of the plasma and red blood cell free amino acid pools and the plasma peptide pool of the portal vein blood of growing pigs. Four pigs, fitted with catheters in a carotid artery and the portal and mesenteric veins, were fed a...

1. A study was conducted with broiler chicks to evaluate the effects of dietary high-methylated citrus pectin (HMC) or low-methylated citrus pectin (LMC) on the performance, nutrient digestibility, morphology of the small intestinal wall and ileal microbial activity. 2. Both pectin products were tested at a dietary content of 30 g/kg using a...

Eighteen cannulated piglets were used in two experiments (six in Experiment 1 and 12 in Experiment 2) to determine the effect of supplementation of the diet with microbial α-galactosidase on the ileal digestibility of the raffinose family oligosaccharides and other nutrients of lupin-based diets. Three semi-purified diets with the seed meal of...

Two experiments were conducted to determine apparent ileal DM and crude-protein (CP) digestibilities in rations fed to pigs. An evaluation was made of Cr2O3 and HCl-insoluble ash as digestive markers. In addition, the effects of body weight (BW) on apparent ileal DM and CP (N x 6.25) digestibilities were studied. In Expt 1, thirteen barrows...

We assessed the use of 15N-labeled dietary proteins as a possible tool for the determination of the true ileal amino acid (AA) digestibility in pigs. The first experiment was designed to study the dietary N excretion pattern at the ileum subsequent to the ingestion of a single 15N-labeled meal. In a second experiment, we compared ileal...
