JOURNAL FREE ACCESSTo improve the recovery of ovarian activity and reproductive performance after parturition, 6 mg of estradiol benzoate (EB) was injected intramuscularly once during days 14-18 (around the period of maturation of the first postpartum dominant follicle) after parturition in dairy cows. The cows were randomly assigned to an estradiol treated-group (n＝164) and an untreated-control group (n＝150). Judging by rectal palpation and progesterone concentration in plasma, 86.0% of estradiol-treated cows ovulated on day 2 and formed a corpus luteum on day 7 after EB injection, compared to only 38.9% in the control group. The ratio of insemination within 60 days of parturition was higher in the estradiol-treated group (68.9%) compared with the control (47.3%).In contrast, there were no significant differences in conception rate after the first insemination and within 100 days after parturition between the estradiol-treated and control groups. The number of anestrous cows more than 100 days after parturition was lower in the estradiol-treated group (11.9%) compared with the control group (24.3%). In conclusion, the injection of EB in the early phase after parturition in dairy cows has significant potential to stimulate the recovery of ovarian activity and decrease the incidence of anestrous cows within 100 days of parturition.View full abstractDownload PDF (267K) -

JOURNAL FREE ACCESSThe effect of CIDR inclusion for seven days after timed artificial insemination (TAI) on reproductive performance was determined in Japanese Black cows. Ovulation was synchronized at one month after normal parturition and was subjected to TAI. Cows were divided into two groups with CIDR inclusion for 7 days at 17 days after TAI (n ＝28) or controls without CIDR (n ＝47). Conception rates with TAI were similar (CIDR 64.3% vs. controls 53.2%, P ＝0.42). The date of return of estrus in open cows were similar (CIDR 28.7 ± 3.9 days vs. control 33.0 ± 26.9 days, P ＝0.22), however there was heteroscedasticty in these groups (P ＜0.01), and the coefficient of variation in CIDR was smaller than in the control. The conception rates of re-AI in open cows both within 7 days after CIDR removal in CIDR and from 18 days to 24 days after TAI in controls were similar. (CIDR 85.7% vs. control 68.3%, P ＝0.47). The inclusion of CIDR for 7 days at 17 days after TAI reduced the dispersion for the timing of the return of estrus in early postpartum Japanese Black cows.View full abstractDownload PDF (227K) -

JOURNAL FREE ACCESSOne hundred and forty-one strains of Enterobacteriaceae (85 strains of Escherichia coli, 20 strains of Klebsiella pneumoniae, 19 strains of Proteus mirabilis, 11 strains of Enterobacter spp., 6 strains of Citrobacter spp.), 31 strains of Pseudomonas aeruginosa, 16 strains of Pseudomonas spp., 9 strains of Acinetobacter baumannii, 12 strains of A. lwoffi, and 11 strains of Pasteurella multocida were isolated from 130 dogs and 33 cats infected with bacteria in one hospital from 2002 to 2010. Twenty strains and 10 strains of multidrug-resistant Enterobacteriaceae (MDRE), which shows resistance to 4 or more classes of antimicrobial agents, were isolated from the dogs and cats, respectively. Thirteen strains, 8 strains, and 5 strains of MDRE were isolated from the urine, skin and subcutaneous abscess, respectively. Although 94% of P. aeruginosa was susceptible to gentamicin, 26% was resistant to ofloxacin. It was considered that attention needed to be paid to a trend of resistance to antimicrobial agents in Gram-negative bacteria.View full abstractDownload PDF (255K) -

JOURNAL FREE ACCESSA 3 years and 2 months old, intact female Golden Retriever dog presented with swelling on the distal end of the left forearm. The dog had no signs of pain or lameness. A radiographic examination indicated that the lesion was mineralized. The lesion was cytologically diagnosed as an osteochondromatous tumor by fine needle aspiration. Surgical resection was subsequently performed. However, the lesion was located deep between the radius and ulna, and was resected incompletely. The resected tissue was histolopathologically diagnosed as osteochondroma. For sixteen months, no recurrence has been identified around the resected site.View full abstractDownload PDF (338K) -

JOURNAL FREE ACCESSA 12-year-old golden retriever suffering seizures was referred to our department. On the first day of the referral, magnetic resonance imaging revealed a tumor mass in the right olfactory bulb. On the 28th day, the mass was removed via a transfrontal craniotomy. Based on the histopathological findings, the tumor was identified as a histiocytic sarcoma. After surgery, the dog underwent CCNU chemotherapy. On the 195th day, neither progress of the local tumor nor distant metastasis could be detected. On the 278th day, the dog died due to respiratory failure. Surgery and chemotherapy may improve survival for dogs with intracranial histiocytic sarcoma, similar to dogs with lung and limb histiocytic sarcoma.View full abstractDownload PDF (378K) -

JOURNAL FREE ACCESSWe report a case of a 12-year-old intact male Welsh Corgi which was referred to our institution for epistaxis. Computed tomography (CT) imaging revealed a mass in the left nasal cavity. The mass was diagnosed as a hemangiosarcoma on the basis of histopathological analysis. The dog was treated with chemoradiotherapy. CT imaging performed at the 124th day after the first visit revealed that the size of the mass had decreased. However, a CT scan at the 208th day demonstrated recurrence, and pulmonary metastasis was identified by a CT scan at the 271st day. The treatment continued at another hospital; however, the dog died at the 331st day. Dogs with hemangiosarcomas in the nasal cavity may respond better to chemoradiotherapy and survive longer than dogs with hemangiosarcomas in the spleen or heart.View full abstractDownload PDF (270K)
