Systematic effects were analysed using mixed linear and mixed nonlinear threshold models. Following effects were regarded in the models applied: sire and mother of the dog as random effects, age at x-raying, sex, birth year and season of the x-rayed dogs, litter size, percentage of x-rayed dogs in each litter and sex ratio of the litter as fixed effects. Sire, mother, sex and age at x-raying showed significant influence on the occurrence of hip dysplasia. The heritability estimates in a hierarchical data design (sire, mother within sire) for the polychotomous trait hip dysplasia were for full sibs h2 = 0.30, for maternal half sibs h2 = 0, 48, and for paternal half sibs h2 = 0.11. Only the heritability estimates of the paternal half sibs seem to be reliable because kennel and breeder effects are confounded with the mother effect. Analysing the frequency of hip dysplasia as all-or-none traits, the heritability estimates were usually lowered by 50%. Selection programmes to reduce frequency of hip dysplasia can be improved if the estimation of breeding values with respect to environmental effects and frequency of hip dysplasia in all relatives will be implemented.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

Parts of intervertebral discs were frozen and sections were subjected to the 3-methyl-benzothiazol-2-on-hydrazone (MBTH) method, which permits differentiation of genetic types and maturation stages of collagen. The annulus fibrosus showed a blue (collagen I) and a violet colour (collagen II) at the external zone. The internal zone was more homogeneous and contained a mixture of both colours (collagen I and II). The nucleus pulposus showed only the violet colour, indicative of collagen II. Discs were also dissected at three different zones and submitted to an extraction technique to obtain collagen, then subjected to SDS-polyacrylamide gel electrophoresis and determination of spectrophotometric reactions of MBTH. Both studies demonstrated type I and type II collagens in the external and internal zones of the annulus fibrosus, but only type II in the nucleus pulposus. Collagen characterization, using this technique, would allow for evaluation in pathologic events of the intervertebral discs as well as for establishing the degree of alteration.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

The 92 piglets were divided into the following 5 groups: swimmers with infection (S-I; n = 19); swimmers without infection (S; n = 19); control piglets with infection (K-I; n = 21); controls without infection, but direct (K1; n = 16) or indirect contact (K2; n = 17) with experimentally infected animals.

Incidence and intensity of pneumonia were significantly higher in the groups with thermomotoric stress (independent from the mode of infection) than in the non-stressed groups. The M. hyorhinis pneumonia was characterized by a limited expansion and a trend to restitution.

MZ 1.3].","authors":"J Hins, F P Gruber","doi":"","DOIUrl":"","url":null,"abstract":"DNA samples from different inbred strains and F1-hybrids, from two outbred strains and from transgenic animals of the species Mus musculus were tested according to the \"DNA fingerprint\" technique (Jeffreys et al., 1985) using the B.E.S.T.-probe MZ 1.3 (Fa. Biotest, Frankfurt) and the restriction endonuclease Hinf I. In addition, the same method was applied to two cell types i.e. BALB/3T3 clone A 31 and 3T3 B-SV40. The DNA fingerprinting technique with probe MZ 1.3 proved to be a reliable method for genetic monitoring of different strains of mice. All inbred strains tested as well as their substrains could be identified and distinguished from each other without any doubt. Congenic and transgenic individuals, however, were identical with their background strains. After several in vitro passages, cells from cultures showed the similar DNA configuration as the donor strains. Within outbred strains, it was possible to quantify heterozygosity by the configuration of the DNA-patterns. These results suggest that it might be appropriate to replace the mathematically estimated inbreeding coefficient by so-called identity-coefficient (IK), which would depend on the probe and the restriction endonuclease used (e.g. IKMZ 1.3/Hinf I). Using the MZ 1.3 probe, the DNA fingerprint technique allows a unique genetic identification of different strains of mice and offers, furthermore, the possibility to use a colour kit rather than the usual P-32 marker.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.
