Long-finned pilot whales (Globicephala melas) are highly social cetaceans that live in matrilineal groups and acquire their prey during deep foraging dives. We tagged individual pilot whales to record their diving behaviour. To describe the social context of this individual behaviour, the tag data were matched with surface observations at the...

The QWERTY concept, a powerful concept for evaluating the environmental consequences of end-of-life processing of consumer electronic products

Huisman, J. (author), Ansems, T. (author), Feenstra, L. (author), Stevels, A. (author), TNO Milieu, Energie en Procesinnovatie (author)

The QWERTY concept (Quotes for environmentally WEighted RecyclabiliTY) focuses on the determination of environmentally weighted recycling scores rather than weight-based recycling scores. The approach describes precisely what is happening in end-of-life scenarios from the environmental perspective. It is a very powerful concept in re-thinking...

Thirty patients with early and continuously treated phenylketonuria (PKU) between 8 and 20 years of age were compared with 30 controls, matched individually for age, sex, and educational level of both parents, on behaviour rating scales for parents and teachers as well as a school achievement scale. PKU patients, as a group, demonstrated more...

The concept of digestible amino acids in diet formulation for pigs

Mosenthin, R. (author), Sauer, W.C. (author), Blank, R. (author), Huisman, J. (author), Fan, M.Z. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)

There is sufficient evidence that ileal rather than fecal amino acid digestibility values provide a more reliable estimate of protein digestion and amino acid absorption. In addition to differences in ileal amino acid digestibility values between feedstuffs there are large differences in ileal amino acid digestibility values within the same...

Apparent protein digestibility and recovery of endogenous nitrogen at the terminal ileum of pigs fed diets containing various soyabean products, peas or rapeseed hulls

Grala, W. (author), Verstegen, M.W.A. (author), Jansman, A.J.M. (author), Huisman, J. (author), van Leeuwen, P. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)

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...

Prefrontal dysfunction in early and continuously treated phenylketonuria

In this study, we tested the hypothesis that patients with early and continuously treated phenylketonuria (PKU) are selectively impaired in cognitive functions dependent on the prefrontal cortex (PFC) over a wide age range. Thirty-six patients with PKU between 8 and 20 years of age and 36 controls matched for age, sex, and educational level of...

Nitrogen utilization in pigs fed diets with soybean and rapeseed products leading to different ileal endogenous nitrogen losses

Nitrogen (N) balance was determined in 36 pigs (BW 24 to 30 kg) fed diets inducing different ileal endogenous N losses (ENL). We tested the hypothesis that enhanced ENL may be indicative of a higher recycling of endogenous proteins that will induce a greater urinary N loss and a lower efficiency of the dietary N utilization for retention. The...

Six barrows of an average initial BW 27.5±1.2 kg were used. Each pig was fitted with two cannulas in different segments of the small intestine: pig 1 in the duodenum (C1) and upper jejunum (C2), pig 2 in C2 and the lower jejunum (C3), pig 3 in C2 and C3, pig 4 in C1 and the terminal ileum (C4), pig 5 in C3 and C4, pig 6 in C1 and C4. Pigs were...

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...

The use of 15N-labeled dietary proteins for determining true ileal amino acid digestibilities is limited by their rapid recycling in the endogenous secretions of pigs

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...
