Preliminary data on metabolic profile of okapis with glucosuria Sarah Depauw1, An Cools2, Francis Vercammen3, Eline Praet2, Geert Janssens2 1Odisee College University, Sint-Niklaas, Belgium; 2Laboratory of Animal Nutrition, Faculty of Veterinary Medicine, Ghent University, Merelbeke, Belgium; 3Centre for Research and Conservation, Royal Zoological Society of Antwerp, Antwerp, Belgium. Correspondence email: Currently, it is recognized that glucosuria in captive okapis is a worldwide phenomenon. Urine sampling of okapis from the Epulu Okapi Reserve in the Democratic Republic of Congo excluded the presence of glucosuria in the wild, thereby indicating captive management factors to be the cause. Although there is a general belief that feeding mismanagement of this strict browser causes glucosuria, the phenomenon still remains unexplained. Moreover, a drastic decrease in sugar and starch content in the diet did not reduce glucosuria in 4 adult captive okapis. However, this diet still contained considerable amounts of highly fermentable fiber, in contrast to browse. Rumen acidosis and laminitis occur within the captive browsing ruminant population, which are both induced by gut fermentation imbalances caused by highly fermentable carbohydrates. We hypothesize that glucosuria in the captive okapi is also linked to imbalances in foregut fermentation processes. Frozen urine samples (10) from 4 glucosuric okapis of Antwerp Zoo were available, with samples from different life stages per animal. From 1 okapi, urine samples before the onset of glucosuria were also present. Samples were analyzed for glucose, free amino acid and acylcarnitine content. Acylcarnitines are a reflection of the corresponding acyl coenzyme A compounds, that indicate the way and extent nutrients are used for energy. Despite difference in life stage or severity of glucosuria, urinary glucose concentrations were positively correlated with metabolites derived from gut fermentation processes (acetylcarnitine (r=0.976; P< /0.001), propionylcarnitine (r=0.848; P< /0.001)). Although this might be a first indication for the link between glucosuria and fermentation, this requires further assessment, since these metabolites can, at least partly, also originate from other metabolic processes. Furthermore, the results suggest that the glucose metabolism is not the only problem in these animals, since multiple positive correlations were found between urinary glucose concentrations and free amino acids (e.g. valine, r=0.979= 0.96; P< /0.001; leucine, r=0.978; P< /0.001). The lack of creatinine measurements implies that certain correlations may only exist because of dilution effects. Therefore, also metabolite ratios were tested, since ratios are independent of dilution. Several metabolite ratios were also tightly correlated with glucose concentration: for instance propionylcarnitine:acetylcarnitine positively correlated with glucose (r=0.666; P=0.009) suggesting a shift to a higher ruminal propionate:acetate ratio. Captive okapis suffering from glucosuria thus show an altered metabolic profile in the urine that can help explain the phenomenon. The profile indicates that it is therefore still worthwhile exploring more browse-based diets for okapis in the prevention of glucosuria.

Welfare of dogs housed on concrete versus mesh floor with plastic coating in a commercial breeding facility

Welfare of dogs housed on concrete versus mesh floor with plastic coating in a commercial breeding facility Van Impe, Isabelle, Depauw Sarah, Vervaecke, Hilde Odisee University College, Agro-& Biotechnology, Animal Welfare and Behaviour, Sint-Niklaas, Belgium; An important aspect of a dogs’ health and behavioural and affective wellbeing is determined by the choice of floor substrate. The Belgian law prescribes that the floor should not wound the feet, it should be flat, easy to keep dry and clean. A wooden floor is excluded and maximally half of the floor can consist of a mesh, only of a type that sufficiently supports the soles. We evaluated the effect of mesh floor with plastic coating versus concrete floors on the welfare of dogs in a commercial dog breeding facility. In 14 individually housed dogs, behavioural observations were carried out on concrete as well as on mesh floor, during four times 15 minutes, to score activity, positive and abnormal behaviours. The dogs had been housed several months on either of these floors. We found that they were significantly longer (p< /0.036) and more frequently active (p< /0.036) on concrete floor (paired-samples test), irrespective of the floor type they were previously habituated to. Similarly, the dogs showed longer resting behavior on the mesh floor (p< /0.039). Results with regard to positive and abnormal behaviours were less conclusive. We carried out a preference test offering a choice between concrete and mesh floor during one hour, for 17 individuals. The dogs spent significantly more time on the mesh floor, irrespective of their previous habituation to either floor type (p< /0.015, paired samples test). In a sample of 14 new dogs interdigital rubor, redness of insole cushions, or digital alopecia was often observed. However, their prevalence was not significantly different between floor types (chi-square, p< /0.690). The difficulty of interpreting the behavioural results with regard to welfare will be discussed. By combining the results with a thorough literature study and by comparing the international legislation, lessons were drawn to improve current legislation.
