JOURNAL FREE ACCESSThe effect of salt blocks with biotin content (300mg/kg and 100mg/kg, HBFB and LBFB) was examined on serum biotin concentrations and the incidence of the hoof diseases in 217 dairy cows. These salt blocks were fedad-libitumover the course of one year. One year from the commencement of this trial, the serum biotin concentrations of these cows were significantly (P<0.001, P<0.01) elevated in the HBFB and LBFB groups: 589±432pg/mlto 1, 101±1, 058pg/mland 473±250pg/mlto 667±554pg/ml, respectively. The number of cows with hoof disorders declined significantly (P<0.001) in the HBFB group, from 62/121 cows (51.2%) in the initial examination to 25/121 cows (20.7%) after one year. In normal cows, the incidence of hoof disease was significantly (P<0.05) fewer in the HBFB group (8/59 cows: 13.6%), than that in the non-HBFB group (17/54 cows: 31.5%). These results suggest that HBFB elevates the serum biotin concentration, decreases the frequency of hoof disorder, and prevents hoof disease in dairy cows.View full abstractDownload PDF (1451K) -

JOURNAL FREE ACCESSFive young calves (aged one month) showing fever, cough, rhinorrhea and/or hanging ears were investigated for microbial pathogens. From the nasal cavity, Reoviruses (2/5), Mycoplasma bovirhinis (3/5) and/or Pasteurella multocida (4/5), and from the external ear, Reoviruses (3/5) and/or Mycoplasma bovis (1/5) were isolated. The isolated Reoviruses were reacted with anti-Reovirus Type I and type II antisera in the hemagglutination inhibition test. This is the first report of the isolation of Reovirus from the external ears of calves in Japan. Further investigation of the pathogenesis of the isolated virus in calves is necessary.View full abstractDownload PDF (1418K) -

JOURNAL FREE ACCESSFour miniature horses died within two days of feeding on wild grasses, making circling movements and suffering from convulsion and astasia. At necropsy, the horses showed impaired blood clotting, their lungs and brains were congested, various organs were fragile, and patches of hemorrhage in organs were observed. Although water hemlock was found in the grass field, it was difficult to confirm that water hemlock had been ingested. The gastric contents of the deceased horses were too fine for macroscopic identification of the consumed grasses. Cicutoxin was identified in the gastric contents of two deceased horses by means of gas chromatography-mass spectrometry. These observations showed the effectiveness of gas chromatography-mass spectrometric analysis of the gastric contents in the diagnosis of plant poisoning.View full abstractDownload PDF (1726K) -

JOURNAL FREE ACCESSAs for the diagnosis of psittacine beak and feather disease (PBFD), it has been made clear that the genetic variant virus in the budgerigar cannot be detected when using the traditional PCR, and the utility of a PCR method developed by Ogawa et al. that is able to detect genetic variant virus widely was confirmed. One thousand and seventy psittacine birds presented to 58 animal hospitals and kept in 12 pet shops were epidemiologically examined for PBFD using the new PCR method. The positive rate of 300 birds from pet shops was 16.7% while that of 770 birds from general families was 19.2%, and overall 18.5%. The PBFD virus is widespread throughout Japan, and it was clarified that the positive rate of PBFD depended on the bird species. Species with high positive rates were budgerigars (40.1%), cockatoos (24.2%) and African grey parrot (21.2%). Differences in the appearance of clinical signs were evident among species.View full abstractDownload PDF (1652K) -
