JOURNAL FREE ACCESSChanges in serum total-cholesterol (TC) concentration and carcass traits were studied in Japanese Black beef cattle during the first and middle fattening periods. The animals' feed contained various neutral detergentfibers (NDF). In animals whose feed was high in NDF, serum TC concentrations were significantly higher than in other cattle groups. Furthermore, branch meat weight and sirloin wick areas tended to be large; and perkg unit prices of branch meat were significantly high. Studies were conducted on relations among serum vitamin A (VA) concentrations, beef-marbling standard number (BMS No.), and changes in serum VA concentrations in cattle ranked as A-5, A-4, and A-3. No correlation was recognized between serum VA concentrations and BMS No.on the day following introduction and the day before shipping. At ages of 14 and 15 months, serum VA concentrations in cattle ranked A-5 were significantly lower than those in cattle ranked A-4 and A-3. Keeping serum VA concentrations low during the middle period and giving feed with high NDF levels in the first-middle period may be important to the production of high BMS Nos.and heavy branch meat.View full abstractDownload PDF (693K) -

JOURNAL FREE ACCESSBetween 1997 and 2003, approximately 10, 000 post-weaned piglets (30 75 days old) died on three swine farms on Kyushu. The outbreaks of sudden death lasted from 14 to 19 months. The highest monthly mortality rate was 25%. Predominantly enterotoxaemic Escherichia coli (ETEEC) was isolated from the intestinal contents of the dead piglets and from the feces of sickish piglets. On the basis of these findings, the cases were diagnosed as mass outbreaks of Escherichia coli enterotoxaemia. Decreasing such mass outbreaks of sudden death may depend on treating sickish animals with antimicrobial agents and preventative administration of probiotics to sows, suckling piglets, and young weaned pigs. Such outbreaks continue to occur on the farms in question.View full abstractDownload PDF (576K) -

JOURNAL FREE ACCESSHyperglycemia, hypoinsulinemia, glucosuria, and ketonuria were observed in a Japanese Black calf with anepithymia, diarrhea, and ananastasia. Histopathologic examination revealed nonpurulent inflammatory lesions localized mainly in pancreatic islets. On the basis of these findings, the case was diagnosed as diabetes mellitus. In addition, hypercortisolism, adrenocorticohyperplasia, and systemic hyperadiposis suggested hyperadrenocorticism.View full abstractDownload PDF (2791K) -

JOURNAL FREE ACCESSClinical examination of a Holstein cow (aged 7 years and 3 months) with cyanosis, jugular-vein distention, and non-inflammatory edema in the brisket and ventral abdomen revealed decreased intensity of heart sounds, marked hydropericardium, and increased serum γ-globulin values. Gross solid opaline masses were found over the epicardium, and the pericardial fluid was distinctly blood-like. Histopathologic examination resulted in a diagnosis of the neoplastic masses as malignant mesothelioma.View full abstractDownload PDF (2718K) -

JOURNAL FREE ACCESSSmall mites taken from the nostrils of a Labrador Retriever (7 years old, 28kg boby weight, indoor-housed) were observed. They were ovoid in shape with an average length of 695 (628-808)μm and had average width of 464 (439-533)μm and had 10 pairs of doral setae. The site of the parasites and morphological findings indicated that they were Pneumonyssoides caninum larvae.View full abstractDownload PDF (554K) -

JOURNAL FREE ACCESSA very hard mass in the left thoracic wall of a six-year-old, male, mixed-breed cat involved sixth to eighth ribs. Incisional biopsy resulted in a histological diagnosis of osteochondromatosis. The left thoracic wall resection, including sixth and eighth ribs were performed. The resulting chest wall defect was closed with a polytetrafluoroethyene mesh sheet. One year later, the cat was clinically normal without any recurrence or new lesions.View full abstractDownload PDF (3306K) -

JOURNAL FREE ACCESSIn a case of urinary obstruction caused by cystoliths in a 6-month-old male cat, ultrasound and radiographic examinations detected a calculus (1cm in diameter) in the bladder. After cystotomy to remove the calculus, the urethral canal was opened by a modified perineal urethrostomy utilizing preputial mucosa. Two days after surgery, the patient was in good enough general condition to be discharged. The calculus was composed of mainly magnesium ammonium phosphate (>98%) and a small amount of calcium phosphate.View full abstractDownload PDF (1583K) -

JOURNAL FREE ACCESSSera from pet cats and dogs in Yamaguchi Prefecture were analyzed by means of indirect immunofluorescence for antibodies to Bartonella henselae. Of 126 cats, 23 (18.3%) were positive for the B. henselae IgG antibody and 1 (0.8%) for the IgM antibody. The seropositive rate (3.2%: 1/31) of the B. henselae IgG antibody in young cats (<1 year old) was significantly lower than that (28.3%: 13/46) in older cats (from 1 to 3 years old)(P<0.05). Of 283 dogs, 19 (6.7%) were positive for the B. henselae IgG antibody and 10 (3.5%) for the IgM antibody. Prevalence of the B. henselae IgG antibody was significantly higher in male dogs than in female dogs (P<0.05).View full abstractDownload PDF (972K)
