JOURNAL FREE ACCESSCows with dermatological lesions and pruritus caused by naturally occurring infestation with Chorioptes texanus were observed in a tie-stall dairy farm in Kagoshima Prefecture, Japan. Sixty-two Holstein cows in the farm were treated with 0.5 mg/kg of eprinomectin and then evaluated for pruritus behavior, lesions, cow comfort, and milk yield. Furthermore, cows were divided into two groups by the presence or absence of pruritus behavior, and lesions and milk yield were then compared. The rates of both tail swishing indicating pruritus and lesion score significantly decreased after treatment. The rate of standing idle, an indicator of cow comfort, significantly decreased and the 305-day corrected milk yield increased after treatment. While the tail swishing-positive group had a higher lesion score and little variance in milk yield after treatment, the tail swishing-negative group had an increase in milk yield. Thus it can be said that the eprinomectin treatment had therapeutic efficacy on bovine chorioptic mange. In addition, our data suggests that it could be important to treat in the early stage of dermatitis onset to maintain cow comfort and the productivity of affected cows.View full abstractDownload PDF (936K) -

JOURNAL FREE ACCESSJapanese black cattle (16-years-old and an 8-month-old female), which was clinically diagnosed with mesenteric fat necrosis, was presented to the meat inspection center. At dismantling, multiple white nodules were found on the serosal surface of the liver, spleen, omentum, diaphragm, abdominal wall and lungs. Grossly, nodular lesions were not observed in the pre-existing bone tissue. Histopathologically, all of the tumors were composed of osteoid trabecula and osteoblastic tumor cells. Tumor cells showed low cell atypia and occasional mitotic figures, but there was metastasis in the lungs. Immunohistochemically, tumor cells showed positive reaction to osteopontin, keratin sulfate, S-100 and vimentin. Based on these findings, the present case was diagnosed as extraskeletal osteosarcoma which is relatively rarely reported in cattle.View full abstractDownload PDF (2688K) -

JOURNAL FREE ACCESSIn this study, 10 diarrhetic Japanese black calves with severe metabolic acidosis without clinical signs of dehydration were assessed in order to determine the effects of withholding milk on their acid-base equilibrium, fecal scores, and treatment. All calves included in the study were administered sodium bicarbonate solutions intravenously. Milk was withheld in five calves (withholding milk group, n＝5) for 24 hours from the first medical examination, while the other five calves (control group, n＝5) were provided milk. Twenty-four hours after medical treatment, significant increase was observed in the pH of the blood and in the bicarbonate ion concentration, while the anion concentration was significantly decreased in the group who had milk withheld. Furthermore, the pH of the blood of the control group was significantly increased, while no change was observed in the concentrations of bicarbonate ions and anions. The fecal score showed a significant decrease in the group that had milk withheld. Twenty-four hours after medical treatment, no significant difference was observed in the blood pH and fecal scores of the group that had milk withheld and the control group, however, the number of medical examinations was decreased only in the group that had milk withheld. These results suggest that withholding milk during treatment was beneficial in diarrhetic Japanese black calves with severe metabolic acidosis without clinical signs of dehydration.View full abstractDownload PDF (675K) -

JOURNAL FREE ACCESSWe examined the effects of different compounds and formulations of synthetic glucocorticoids (GCs) on the hypothalamic-pituitary-adrenal axis (HPAA) and the hypothalamic-pituitary-thyroidal axis (HPTA) in dogs. Sixteen dogs were divided into three GC groups and one control. The three GC groups were administered anti-inflammatory doses of prednisolone, betamethasone, and methylprednisolone acetate, respectively. An adrenocorticotropic hormone (ACTH) stimulation test was performed for the evaluation of the HPAA, and measurements of serum thyroxin and thyrotropin concentration were used for an assessment of the HPTA. All the GC groups showed a significantly decreased response to the ACTH stimulation test after the GC administration, compared with the control group. The betamethasone group showed the greatest decrease in HPTA functions of all the GC groups after the treatment. A careful re-evaluation of HPAA and HPTA functions should be required when long-acting glucocorticoids are used, even if they are used in anti-inflammatory doses in dogs.View full abstractDownload PDF (1000K) -

JOURNAL FREE ACCESSA peach-faced lovebird with abnormal red feathers was used as a validated case for diagnostic therapy, and an improvement in the feather color was dependent on Thyradin administration. In addition, Thyradin was administered to 19 lovebirds with abnormal red feathers, and the feather color improved in all cases. To resolve the pathogenesis of this condition, epidemiological information and blood test data were collected for all the birds. This pathological condition is common in older female birds with obesity and strong estrus. High values of alkaline phosphatase, total cholesterol, and triglycerides were obtained in all cases; however, these abnormal values may be due to estrus. The present study findings suggest that hypothyroidism is closely related to the appearance of abnormal red feathers.View full abstractDownload PDF (1313K)

JOURNAL FREE ACCESSAmong 431 cattle which were judged as unfit for human consumption through veterinary inspection, visceral organs including the heart, liver, kidneys, spleen and tongue of 19 randomly selected cattle were examined histopathologically and immunohistochemically. Of these 19 cases, Ten (52.6%) had AA amyloid deposits. According to details of condemnation, the amyloid deposition was observed in four of five cases with severe edema (80.0%), six of 13 cases with sepsis (46.1%), and none of one case with pyemia. Those cases were all female Holsteins 37-130 months of age. The amyloid deposition was often observed in the liver and kidney, and some cases had the deposition in the tongue. In macroscopic findings, although two cases of the kidneys with significant amyloid deposition were swollen and yellowish in color, noteworthy pathological changes were not observed in the other cases. We consider that it would be necessary for further surveillance of amyloidosis during veterinary inspection of cattle in abattoir.View full abstractDownload PDF (2976K)
