    Training success in group-housed long-tailed macaques (Macaca fascicularis) is better explained by personality than by social rank2016In: Applied Animal Behaviour Science, ISSN 0168-1591, E-ISSN 1872-9045, Vol. 177, p. 52-58Article in journal (Refereed)
    Abstract [en]

    Using training to prepare laboratory animals for biomedical research is one important behavior management task. With increased knowledge about factors influencing training success, training programs may be optimized, resulting in a refinement of primate husbandry. Even when animals are trained under the same conditions there are individual differences in how they respond to training. The current paper focuses on two of the factors potentially influencing training success: social rank and personality. Five observers rated the personality and the social rank of 34 long-tailed macaques (Macaca fascicularis) in an observer trait rating survey. Training success was measured in 22 of these individuals and from four of their shaping protocols; hand-feeding, target training, presenting hands and presenting feet. From the factor analysis four personality traits could be identified: 'Emotionality', 'Activity', 'Sociability', and 'Tolerance'. A Multiple linear regressions with backward elimination showed that the personality trait 'Activity' was associated with training success (adj.R-2 = 0.71, p < 0.0005), and unexpectedly, social rank had less influence (adj.R-2 = 0.30, p = 0.005) on training success in group-housed long-tailed macaques. We propose that training success can be conceptualized as consisting of two components: access to the trainer and problem solving. In the case of personality, the two components combine to promote training success: curious animals gain access to trainers, and playful animals are good problem solvers; both these adjectives were present in the trait 'Activity'. In contrast, with regards to rank, qualities that increase access to the trainer (dominance) and traits that promote problem solving (subordinance) counteract one another, potentially explaining why in this study, training was better explained by personality than by rank. We discuss the importance of successfully training different types of personalities in order for the selection of animals in biomedical research to remain random and non-biased, rather than excluding those that do not respond well to training.

    Microphthalmia-associated transcription factor mutations are associated with white-spotted coat color in swamp buffalo2015In: Animal Genetics, ISSN 0268-9146, E-ISSN 1365-2052, Vol. 46, no 6, p. 676-682Article in journal (Refereed)
    Abstract [en]

    A candidate gene analysis of the microphthalmia-associated transcription factor (MITF) gene was used in an attempt to identify the genetic basis for a white-spotted coat color phenotype in the Asian swamp buffalo (Bubalus bubalis carabanensis). Ninety-three buffaloes32 solid, 38 spotted and 23 white individualswere Sanger-sequenced for all MITF exons as well as highly conserved intronic and flanking regions. MITFcDNA representing skin and iris tissue from six spotted, nine solid and one white buffaloes was also Sanger-sequenced to confirm detected mutations. Two independent loss-of-function mutations, a premature stop codon (c.328C>T, p.Arg110*) and a donor splice-site mutation (c.840+2T>A, p.Glu281_Leu282Ins8), both of which cause white-spotted coat color in swamp buffaloes, were identified. The nonsense mutation leads to a premature stop codon in exon 3, and likely removal of the resulting mRNA via nonsense-mediated decay pathway, whereas the donor splice-site mutation leads to aberrant splicing of exon 8 that encodes part of a highly conserved region of MITF. The resulting insertion of eight amino acid residues is expected to perturb the leucine zipper part in the basic helix-loop-helix leucine zipper (bHLH-Zip) domain and will most likely influence dimerization and DNA binding capacity. Electrophoretic mobility shift assay was performed using mutant and wild-type MITF proteins and showed that the mutant MITF protein resulting from the splice-site mutation decreased invitro DNA binding capacity compared to wild-type MITF. White-spotted buffalo bulls are sacrificed in funeral ceremonies in Tana Toraja, Indonesia, because they are considered holy, and our results show that genetic variation causes a tie to the cultural use of these buffaloes.
