JOURNAL FREE ACCESSOver a period of 2 years, we investigated hoof diseases (sole ulcers and white-line disease) in a herd of 64 to 72 Holstein cows that were being milked and were housed in cubicles. During the first year, hoofs were trimmed once annually at no definite times; and hoof diseases were treated whenever farmers noticed lameness. During the second year, abnormal gait and overgrown hooves were screened and trimmed once a month. Hoof diseases were treated when detected. Incidence of hoof disease was higher in the second year (25.6%) than in the first year (19.3%); but the culling rate consequent upon hoof disease was lower in the second year (3.1% vs. 0.7%). Milk loss during the 3 2-week periods following diagnosis compared with that during the 2 weeks before diagnosis was 3.1, 4.3, and 5.0 kg/day in the first year and 1.4, 1.5, and 2.5 kg/day in the second year. Loss was significantly greater in the first than in the second year. Thus, during the second year, the monthly foot-care program prevented milk loss associated with hoof diseases.View full abstractDownload PDF (697K) -

JOURNAL FREE ACCESSA serological survey of cattle (Holstein and Japanese Black) bred in Tochigi Prefecture detected Neospora caninum in 21 of 35 cities and towns (60%) in the case of Holstein animals and 3 of 15 cities and towns (20.0%) in the case of beef cattle. It was present on 55 of 170 Holstein farms (32.4%) and 5 of 23 beef-cattle farms (21.7%). It was detected in 120 of 1, 962 head of Holstein cattle (6.1%) and 13 of 294 (4.4%) head of beef cattle. Antibody rates of cattle used as recipients of the embryo-transfer (ET) technique on 8 of 11 sero-positive farms were distributed within the range 1.2-25%. During a continuous survey conducted for one year on 2 farms (dairy and Japanese Black cattle), no animals showed increases or positive conversion of antibody titer. Nonetheless, all calves from sero-positive cows demonstrated Neospora caninum antibodies. At our suggestion, sero-positive Holsteins were subjected to planned culling; and sero-positive Japanese Blacks were used either as beef cattle or as ET donors.View full abstractDownload PDF (668K) -

JOURNAL FREE ACCESSA pharmaco-kinetic study of cisapride in cows was made to provide a basis for the clinical use of the drug. Cisapride (0.1 mg/kg) was intravenously administered to 5 clinically healthy cows; and serum was taken at 10, 20, 30, 40, 50, 60, 80, 100, 120, 150, 180, 240, 300, and 360 min after administration. Serum cisapride concentrations were measured by means of the HPLC method, and pharmaco-kinetic parameters were analyzed on the basis of a 2-compartment model. Serum half-life was 1.90±0.18 (mean±SD) hr; total body clearance was 23.17±1.05 ml/kg/min; volume of distribution at a steady rate was 2.95±0.45 l/kg; and residence time was 2.11±0.29 hr.View full abstractDownload PDF (468K) -

JOURNAL FREE ACCESSUltrasound-guided biopsy using endoscopic biopsy forceps was attempted in 10 dogs with urinary-bladder tumors. The forceps used were 1.8mm wide and mounted in an 8 French catheter. Before forceps insertion, generally local anesthetic was infused into the urethra, although in some cases the dog was sedatcd. The diameter of the urinary-bladder cavity was maintained between 2 and 3 cm under ultrasonographic guidance by either urine removal or infusion of a saline. Opening and closing the forceps proved to be strongly echogenic, permitting easy grasping and removal of target tissues. In all cases, tissue specimens obtained were 2mm long. Histological examination of the mucosal epithelium and part of the sub-mucosal tissue made it possible to diagnose transitional cell carcinoma in 9 dogs and fibrosarcoma in one dog. Sample volumes were sufficient for pathological diagnosis. The technique proved appricable to diagnosis of mucosal lesions of the urinary bladder.View full abstractDownload PDF (3493K) -

JOURNAL FREE ACCESSStudies were made of the feline immunodeficiency-virus (FIV) antibody, the feline leukemia-virus (FeLV) antigen, and the feline coronavirus (FCoV) antibody in Japanese domestic cats. In cases in which pleural and peritoneal exudates led to suspicion of feline infectious peritonitis (FIP), 26.3% of the examined animals were positive for FIV and 36.8% were positive for FeLV. In cases of upper respiratory diseases, 35.7% were positive for FIV and 21.4% for FeLV. The values were higher than those for clinically healthy cats: 9.3% positive for FIV and 8.1% positive for FeLV. These findings suggest that FIV and FeLV infections may contribute to the appearance of FIP and respiratory infections. The percentage of cats positive for FCoV (47.7%) was much higher than those for FIV and FeLV in healthy cats. This suggests that FCoV is highly contagious. The extremely high prevalence of FeLV (66.7%) in anemic cats indicates that FeLV tests are indispensable diagnostic tools in dealing with cats developing anemia.View full abstractDownload PDF (1178K) -

JOURNAL FREE ACCESSAll the premolars and molars of 14 cats under medical treatment for gingivo-stomatitis and suffering severe pain during eating were extracted. Thereafter macroscopic oral inflammation disappeared in 5 (35.7%) of the cats and pain during eating in 6 (42.9%). The overall-symptom rate of improvement for macroscopic faucitis was 71.4%(10 of 14); the corresponding rate for eating pain was 64.3%(9 of 14). Cats suffering from severe faucitis before treatment and those infected with FeLV and/or FIV tended to respond poorly to the therapy.View full abstractDownload PDF (1483K) -
