JOURNAL FREE ACCESSThe objectives of the present study were to investigate the associations among four three-month periods and three herd groups with the percentage of sows mating within six days post weaning (PSW6) by parity. Three herd groups were built on the basis of the upper and lower 25th percentiles of pigs weaned per mated female per year. The four periods were defined as January to March, April to June, July to September and October to December, according to the sows' weaned months. The selected 112 herds included 71,451 litters farrowed in 2005. The mean PSW6 (±SEM) was 82.9 (±0.14) %. Sows weaned from July to September had a lower PSW6 than those from October to December for any parity (P ＜0.05). In parity 5 or higher, there was no difference in PSW6 among the four period groups in high-performing herds. In conclusion, it is critical to increase PSW6 from July to September to improve herd productivity.View full abstractDownload PDF (206K) -

JOURNAL FREE ACCESSThymidine kinase is an enzyme related to DNA synthesis. Recently, serum thymidine kinase (STK) activity has been reported as a useful marker of bovine leukosis. In an effort to achieve earlier detection of enzootic bovine leukosis (EBL), we measured STK activity in cows at a farm tainted by bovine leukemia virus (BLV). We found that a Holstein cow aged 10 years and 9 months without any clinical symptoms showed higher STK activity, and the cow was diagnosed as having EBL. Evaluation of STK activity in a herd contaminated with BLV is clinically useful for early detection of EBL.View full abstractDownload PDF (282K) -

JOURNAL FREE ACCESSThe effect of the season, thermo-humid index (THI) and days in milk (DIM) on the reproductive performance were investigated over eight years (n ＝3,581) in two dairies with different altitudes (38 m vs. 795 m). There was no difference in heat detection rate between the dairies (39.1% vs. 40.9%), whereas the conception rates (CR) fell below 20% when THI exceeded 72 in the dairy at lower altitude. The CR declined to less than 14.2% in cows with DIM on 51-110 during summer in the dairy at lower altitude, whereas no seasonal change was identified in the dairy at higher altitude. These results implied a risk of deteriorating performance on reproduction in dairies at lower altitudes resulting from heat stress.View full abstractDownload PDF (316K) -

JOURNAL FREE ACCESSA three-year-old neutered female ferret weighing 800 g was brought to our clinic with anorexia, nausea, and abdominal distension/pain. Clinical examination confirmed dehydration, hyperglycemia, hyperinsulinemia,intraperitoneal lymph node swelling, and splenomegaly. Abdominal X-ray findings suggested gastrointestinal obstruction. A laparotomy was performed. In a portion of the spleen, a mass was detected. Hardening of the pancreas, marked inflammation of fat around the pancreas, and pancreaticoduodenal lymph node swelling-related compression of a portion of the duodenum were observed. Histopathological examination of the extirpated spleen, pancreaticoduodenal lymph nodes, and left pancreatic lobe revealed extramedullary hematopoiesis in the spleen, reactive hyperplasia of the pancreaticoduodenal lymph nodes, and chronic pancreatitis. The clinical symptoms subsided the day after surgery. In the present case, chronic pancreatitis-related pancreaticoduodenal lymph node swelling may have led to obstruction of the digestive tract.View full abstractDownload PDF (326K) -

JOURNAL FREE ACCESSUsing a palate cap with a resilient lining material, the authors achieved successful long-term management of a traumatic palatal defect in a cat and an acquired palatal defect resulting from radiation therapy and local chemotherapy to treat a malignant melanoma in a dog. In the cat with the traumatic palatal defect, surgical attempts to close the defect had been unsuccessful and the palate cap with resilient lining material produced satisfactory results. The palate cap was able to be used for at least two years. In the dog with the acquired palatal defect due to radiation therapy, the palate cap was created on ten occasions, given invasion by the malignant melanoma. As a result, quality of life was able to be maintained for at least one year. The palate cap allows anesthetization for a short time. Management of the acquired palatal defect using a palate cap with a resilient lining material is very compatible with both palatal defects with repetitive dehiscence and acquired palatal defects resulting from therapy for oral malignant tumors.View full abstractDownload PDF (301K) -

JOURNAL FREE ACCESSA six-year-old, mixed-breed dog presented with swelling of the caudal dorsal portion of the left ear. Clinical examination revealed no external ear opening. CT and MRI examinations indicated that the ear canal and tympanic bulla were filled with material and a cytological examination showed only scales of keratin. Since the left auditory canal was enlarged like a cyst and raised the pressure on the ear, total ear ablation and bulla osteotomy was performed. During the operation, the ear canal and tympanic bulla were founded to be filled with a yellow-green material. A histopathological examination revealed that the epithelium of the ear canal formed a fold and the cerumen had accumulated inside. It was confirmed that the material was scales of keratin. Although secondary inflammation from the keratin was seen, no bacteria were cultured. These results suggest this case to be congenital external auditory canal atresia. The post-surgery healing process was satisfactory.View full abstractDownload PDF (455K)

JOURNAL FREE ACCESSTo investigate drug sensitivity and estimate the risk of drug resistance for public health, the authors examined the drug susceptibilities of Escherichia coli and Klebsiella spp., derived from bovine mastitis that occurred in the Ishikari area of Hokkaido from June to September 2006. Eighteen antimicrobial agents used in veterinary and human medicine were selected. A total of 106 E. coli and 34 Klebsiella spp. were tested, and 29.2% of strains of E. coli and 91.2% of Klebsiella spp. showed antimicrobial resistance. However, the resistance rates of E. coli were lower than the indicator bacteria of food-producing animals. All of them were sensitive to the second choice antibiotics widely used with animals and humans. Therefore, it is considered that E. coli and Klebsiella spp. originating from bovine mastitis in the area may have a low direct influence on human health.View full abstractDownload PDF (248K)
