In swine nutrition, little is known about the vitamin D requirements for reproductive processes and bone health. Consequently, the vitamin D recommendation for sows during gestation and lactation is not based on scientific reports. The current study was undertaken to obtain information on the dose-response pattern of 2 vitamin D sources, the commonly used(More)
The aim of this study was to investigate the effects of social contact and milk allowance on social behavior, play behavior, and responses to handling in dairy calves. Forty test calves and 16 companion calves were allocated to 1 of 5 treatments from birth to 4 wk of age: (1) housed singly and fed 5 L of milk/d; (2) housed singly and fed 9 L of milk/d; (3)(More)
The aim of this experiment was to investigate pigs' preferences for rooting materials. Eighteen materials were allocated to six categories each of which consisted of three similar materials based on characteristics such as structure, size of particles, complexity, destructibility and digestibility. Twelve pairs of pigs chose among the three materials of(More)
Technical Reports: This series aims to cover the publication of pre-prints and research papers in an advanced stage of elaboration. The material published should have some original content, but reviews are also suitable. There are, in principle, no size limitations and extended versions with full details that are refer-enced later in the final publication(More)
We considered experiments where animals chose one of all possible simultaneously presented options. The animals might be observed at repeated occasions. In the ethological literature the analysis is often focused on testing the global hypothesis of no difference in preferences by non-parametric methods. This fails to address the estimation of a ranking.(More)

Aortic vascular prosthetic graft infection (AVPGI) with Staphylococcus aureus is a feared post-operative complication. This study was conducted to evaluate the clinical signs and potential biomarkers of infection in a porcine AVPGI model. The biomarkers evaluated were: C-reactive protein (CRP), fibrinogen, white blood cells (WBC), major histocompatibility(More)
