  1. Predicting feather damage in laying hens during the laying period. Is it the past or is it the present?

    Contributor(s):: de Haas, Elske N., Bolhuis, J. Elizabeth, de Jong, Ingrid C., Kemp, Bas, Janczak, Andrew M., Rodenburg, T. Bas

    Feather damage due to severe feather pecking (SFP) in laying hens is most severe during the laying period. However, SFP can develop at an early age and is influenced by early rearing conditions. In this study we assessed the risk factors during the rearing and laying period for feather damage at...

  2. Genetic and environmental effects on piglet survival and maternal behaviour of the farrowing sow

    Contributor(s):: Baxter, Emma M., Jarvis, Susan, Sherwood, Lorna, Farish, Marianne, Roehe, Rainer, Lawrence, Alistair B., Edwards, Sandra A.

    There is growing external pressure to abolish the farrowing crate, however alternative farrowing systems need to equal or surpass the performance (i.e. piglet survival) of more restrictive systems. In order to achieve consistent improvement in piglet survival genetic selection strategies...

  3. Feather pecking genotype and phenotype affect behavioural responses of laying hens

    Contributor(s):: van der Eijk, Jerine A. J., Lammers, Aart, Li, Peiyun, Kjaer, Joergen B., Rodenburg, T. Bas

    Feather pecking (FP) is a major welfare and economic issue in the egg production industry. Behavioural characteristics, such as fearfulness, have been related to FP. However, it is unknown how divergent selection on FP affects fearfulness in comparison to no selection on FP. Therefore, we...

  4. Behavioural responses of pasture based dairy cows to short term management in tie-stalls

    Contributor(s):: Enriquez-Hidalgo, Daniel, Teixeira, Dayane Lemos, Lewis, Eva, Buckley, Frank, Boyle, Laura, O’Driscoll, Keelin

    Dairy cows in experimental grazing herds are often confined for metabolic measurements. The objective of this study was to establish effects of transfer from pasture, to tie-stalls in a metabolism house, then back to pasture, on lying behaviour and locomotion score of lactating cows:...

  5. Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda

    Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.

    This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...

  6. Cryptosporidium spp. in pet birds: genetic diversity and potential public health significance

    Contributor(s):: Qi, M., Wang, R., Ning, C., Li, X., Zhang, L., Jian, F., Sun, Y., Xiao, L.

  7. DNA detection and genotypic identification of potentially human-pathogenic microsporidia from asymptomatic pet parrots in South Korea as a risk factor for zoonotic emergence

  9. Phylogenetic analysis of 626 hepatitis E virus (HEV) isolates from humans and animals in China (1986-2011) showing genotype diversity and zoonotic transmission

    Contributor(s):: Liu, P., Li, L., Wang, L., Bu, Q., Fu, H., Han, J., Zhu, Y., Lu, F., Zhuang, H.

  10. Sentinel surveillance for zoonotic parasites in companion animals in indigenous communities of Saskatchewan

    Contributor(s):: Schurer, J. M., Hill, J. E., Fernando, C., Jenkins, E. J.

  11. Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene

    Contributor(s):: Fabrega, E., Diestre, A., Font, J., Carrion, D., Velarde, A., Ruiz-de-la-Torre, J. L., Manteca, X.

    A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...

  12. Genetically modified laboratory animals - what welfare problems do they face?

    Contributor(s):: Buehr, M., Hjorth, P. J., Hansen, A. K., Sandoe, P.

    In this article, we respond to public concern expressed about the welfare of genetically modified (GM) non-human animals. As a contribution to the debate on this subject, we attempt in this article to determine in what situations the practice of genetic modification in rodents may generate...

  13. Heart rate variability in horses engaged in equine-assisted activities

    BackgroundLoss-of-function variants in the gene encoding filaggrin (FLG) are major determinants of eczema. We hypothesized that weakening of the physical barrier in FLG-deficient individuals may potentiate the effect of environmental exposures. Therefore, we investigated whether there is an...
