A major problem with the interpretation of hematological values is their pronounced variability that is to a great extend caused by non-systematic factors. Differences in breeds and populations are providing evidence for different genotypes in this regard, although there is no information available in swine about the nature and shares of participating genes. Goal of the present paper was to evaluate the additive-genetic share of total variability of traits of the red and white blood cell count. The results are based on 139 F2-pigs of a Pietrain-Meishan-family. Medium to high heritabilities have been estimated for the numbers of neutrophiles, the mean corpuscular hemoglobin concentration and the hemoglobin content, and for the shares of basophile granulocytes, platelets and lymphocytes. No meaningful shares of additive genetic variance were obvious in the other traits. Shares of additive genetic variance of the above mentioned traits argue for the existence of favourable and unfavourable gene variants to be involved in their phenotypic variation. Isolation of these variants might improve the diagnostical use of those traits in the future and provide a measure to advance general health in the pig.","PeriodicalId":49278,"journal":{"name":"Dtw.

A new spherical bait form (diameter 3 cm) containing lyophilised vaccine virus and the recent vaccine baits were used for animal experiments. Four vaccination groups were established in experiment 1 (group 1: recent liquid bait vaccine; group 2: spherical baits containing one dose of the lyophilised vaccine; groups 3 (domestic pigs) and 4 (wild boar): spherical baits containing two doses of the lyophilised vaccine) and two groups in experiment 2 (group 1: recent liquid bait vaccine; group 2: spherical baits with two doses of the lyophilised vaccine). Challenge was carried out with the highly virulent virus strain \"Alfort 187\" (using 100 TCID50 in the first and 1.000 TCID50 in the second experiment). Our results showed that the animals vaccinated with lyophilised C-strain vaccine developed high neutralising antibody titres comparable to those obtained after vaccination with the recent bait vaccine. All pigs which picked up the baits remained healthy after challenge. Neither clinical symptoms nor viremia or virus shedding were observed after infection except in one pig (group 2, experiment 2) which had not consumed the vaccine bait. The surviving domestic pigs and wild boar were tested negative for CSFV and viral RNA at the end of the study. This result demonstrates that lyophilised vaccine may become an effective vaccine formulation for oral immunisation of wild boar against CSF in the near future.","PeriodicalId":49278,"journal":{"name":"Dtw.

Animals of the control groups (I-IV) were treated analogous to the castration groups (V-IX) but not castrated. In groups I and V 15 minutes prior to castration/fixation the piglets were fixed as for injection but not medicated. The injection volume was standardised to 0.5 ml per testes. Local anaesthetics were applicated intratesticularly in five groups and intrascrotarly in two groups. Blood samples were taken shortly before and one, four and 24 hours after castration/fixation. The serum cortisol level was analysed to determine pain induced neuroendocrine stress reaction. To proof the tissue tolerance creatinkinase-(CK) and aspartataminotransferase-(AST) concentration were analysed. One, seven and 14 days after castration the healing process were evaluated by a wound score. Groups I to IV did not show any increase of the serum cortisol level. Contrary one hour after castration the average cortisol concentration of castration groups (V-IX) rose significantly. Cortisol concentration of the medicated castration groups (VI-IX) showed a comparable or even higher cortisol level as the not medicated control group (V). Determination of CK and AST indicated no tissue damage of the application of the local anaesthetics. The administration of local anaesthetics prior to the castration did not have any effect on the wound healing process. The results of this study lead to the conclusion that injection of local anaesthetics show a good tissue tolerance but the call for reduction of the castration pain by presurgical injection of Procaine Hydrochloride or Lidocaine Hydrochloride is not justified.","PeriodicalId":49278,"journal":{"name":"Dtw.

Unexpectedly, in April 1999, a total of nine macaws died after a short period of illness. Clinical signs consisted mainly of anorexia, ruffled feathers and yellowish droppings. A herpesvirus was isolated from brain, trachea, lung, liver, spleen, kidney and intestine of each of the examined dead birds, confirming that all animals succumbed during viraemia. Serotyping of the isolate in cross neutralization tests with reference sera prove that the outbreak was caused by serotype 3 of Pacheco's parrot disease herpesviruses. An autogenous, formalin-inactivated vaccine with adjuvant (aluminium hydroxid gel) was prepared from one of the isolates and injected intramuscularly 14 days and six weeks after the onset of mortality in an attempt to protect the remaining psittacine birds in the zoo from the disease. The autogenous vaccine was well tolerated and was able to rapidly stop virus spread and morbidity and mortality among the psittacine birds. Follow-up studies demonstrate that all nine blood samples from vaccinated birds obtained nine month' after the second vaccination contain neutralizing antibodies. Twenty five month' after vaccination two out of four serum samples were still antibody positive. No herpesvirus was isolated from faecal samples nine and twenty five months after the onset of the outbreak. These data prove that the autogenous vaccine played a major role in containing a severe outbreak of Pacheco's parrot disease in a large collection of psittacine birds.","PeriodicalId":49278,"journal":{"name":"Dtw.
