In seasonally calving dairy herds in the Macalister Irrigation Area of Gippsland, Victoria, cows that had not been observed in oestrus by the start of the mating season and which had inactive ovaries based on rectal palpation and progesterone assay were treated with a hormonal treatment (n = 49). Mature cows had calved at least 40 days previously and 2-year-olds had been calved at least 60 days. The treatment consisted of a norgestomet implant and a norgestomet and oestradiol injection on day 1; prostaglandin analogue Prosolvin) on day 8; withdrawal of implant on day 10 and an injection of PMSG; and fixed time artificial insemination 54 to 56 h after implant withdrawal. This treatment was called the Syncro-mate regimen. Control cows (n = 46) were injected with water on days 1, 8 and 10 and artificially inseminated or served by a bull when seen on heat. Forty seven percent of the treated cows became pregnant within 14 days from the start of treatment compared with 20% of control cows (P less than 0.01). There was an effect of age group on the response to treatment. A greater proportion of 2-year-old cows than mature cows became pregnant within 14 days of treatment (79% of 19 v. 27% of 20; Chi square interaction, treatment by age, 6.4, P less than 0.05). In the younger cows there was also a gain of 22 days in the treatment to conception interval over the control cows (P less than 0.001). It was concluded that the Syncro-mate regimen can be an effective treatment for post partum anoestrus in dairy cows under certain conditions.  相似文献   

The Treatment of Chronic Sinusitis in Six Cats by Ethmoid Conchal Curettage and Autogenous Fat Graft Sinus Ablation     

GAIL I. ANDERSON BVSc  DipvetMed  MACVSc 《Veterinary surgery : VS》1987,16(2):131-134

Six cats with chronic recurrent rhinitis and frontal sinusitis were treated by surgical ablation of their frontal sinuses by the implantation of autogenous fat grafts and curettage of the remaining ethmoid conchae. Deep nasal bacterial cultures and skull radiographs were performed before surgery. Excellent results were achieved in four of six cats and there was significant improvement in two of six cats. Median follow-up time was 15 months. Subcutaneous emphysema over the temporal area was managed by needle aspiration and bandaging. Frontal sinus ablation with autogenous fat graft in combination with ethmoid conchal curettage appears to be an effective treatment for chronic sinusitis in cats.  相似文献   

A Comparison of Nonthreaded, Enhanced Threaded, and Ellis Fixation Pins Used in Type I External Skeletal Fixators in Dogs   总被引：1，自引：0，他引：1  

M. A. ANDERSON dvm  ms    F. A. MANN dvm  ms  Diplomate acvs    C. WAGNER-MANN dvm  PhD    A. W. HAHN DVM  PhD  Diplomate ACVIM    B. L. JIANG PhD  J. L. TOMLINSON DVM  MVSci  Diplomate ACVS 《Veterinary surgery : VS》1993,22(6):482-489

Three different pin types (Ellis, enhanced threaded, and nonthreaded) were used in type 1 external skeletal fixation after transverse osteotomy of the radius and ulna in 12 skeletally mature dogs. Dogs were placed into three groups of four dogs based on the pin type used. Axial extraction forces were determined for each of the pin types after 8 weeks of weight bearing (chronic study). Nine contralateral radii were used to determine axial extraction forces for nine of each pin type not subjected to weight bearing forces (acute study). The force required for extraction of the enhanced threaded and Ellis pins in the chronic and acute studies was not significantly different. The force required to extract the nonthreaded pins was significantly less than that required for the other two pin types. Ground reaction forces had returned to levels measured before surgery by 2 weeks after surgery in the enhanced threaded and Ellis pin groups, however, dogs in the nonthreaded pin group required 4 weeks until normal ground reaction forces were measured. Radiographic evaluations 1,2,4, 6, and 8 weeks after surgery showed no difference among groups in the number of pin tract radio-lucencies, however, the enhanced threaded pins had caused more trans-cortical chip fractures than the other two pin types. None of the pins broke during the eight-week chronic study.  相似文献   

Protection against enzootic pneumonia of pigs: intraperitoneal inoculation with live LKR strain of Mycoplasma hyopneumoniae     

LC. LLOYD  GS. COTTEW  DA. ANDERSON † 《Australian veterinary journal》1989,66(1):9-12

Pigs obtained from a mycoplasma-free piggery were randomised into 4 groups of 9. Groups 1 and 2 were injected by the intraperitoneal route with liquid culture of the LKR strain of Mycoplasma hyopneumoniae. Group 1 was injected once and group 2 twice. Group 3 was made up of pigs inoculated by the intranasal route with the virulent Beaufort strain of M. hyopneumoniae; they served as the source of infection for the challenge. Group 4 were uninfected, uninjected controls. Six weeks after the last injection, groups from 1 to 4 were placed in contact. Seven of the pigs in the 1-dose group and 6 in the 2-dose group were free of lesions at necropsy 6 weeks after challenge. Of the two pigs with lesions in the 1-dose group one had only a small lesion but the other had extensive lesions; it had not shown an antibody response after injection of culture. The lesions in the 3 pigs in the 2-dose group were all small. All 9 control pigs had lesions which varied from medium to large in size. The difference in the incidence of pneumonia between the injected and control groups was significant (P less than 0.05) and the proportion of severely affected pigs in the vaccinated groups was significantly lower (P greater than 0.01). There was no difference between those given one dose of vaccine and those receiving 2 doses.  相似文献

Force Plate Analysis of Triple Pelvic Osteotomy for the Treatment of Canine Hip Dysplasia   总被引：1，自引：0，他引：1  

RON M. McLAUGHLIN Jr.  DVM  DVSC  CRAIG W. MILLER DVM  MVSC Dipiomate ACVS    CONNIE L. TAVES MSC    TREVOR C. HEARN PhD  BSc    NIGEL C. PALMER DVM  PhD  MSC  GAIL I. ANDERSON BVSC  MSC  Dipiomate ACVS 《Veterinary surgery : VS》1991,20(5):291-297

Triple pelvic osteotomy was performed in 15 dogs with bilateral hip dysplasia. Ten dogs were treated bilaterally and five dogs were treated unilaterally. Ten untreated dogs with normal hips served as controls. Force plate analysis, lameness evaluation, and radiography were performed before surgery and at weeks 5, 10, 15, and 28. Three dogs treated unilaterally were euthanatized and the hips were examined grossly and microscopically. Force plate data indicated that young dysplastic dogs transmitted significantly less vertical force through the hip joints than normal dogs. The force transmitted through treated hips reached or approached control levels by week 28 and was significantly greater than the force transmitted through untreated hips. Clinical lameness resolved in 92% of limbs and progression of radiographically detectable degenerative joint disease was minimal. Gross and microscopic degenerative changes in the articular cartilage were similar in the treated and untreated hips. The synovial membrane was less reactive in treated hips.  相似文献   

Survey of resting blood pressure values in clinically normal horses     

B. W. PARRY  M. A. McCARTHY  G. A. ANDERSON 《Equine veterinary journal》1984,16(1):53-58

Resting coccygeal blood pressure values were measured, indirectly, on 296 horses (97 Thoroughbreds, 97 Standardbreds and 102 hacks). Blood pressure was found to vary with the class of horse examined; on average Thoroughbreds had significantly higher values than Standardbreds and hacks, whereas blood pressures of the last two groups were not significantly different. There was no demonstrable effect of sex, height or heart rate on blood pressure, but temperature and age did influence the value recorded. Mean (± sd) (n = 296) coccygeal uncorrected values (systolic pressure/diastolic pressure) were 112.1 ± 16.5/77.3 ± 14.3 mmHg. Allowing for bladder width to tail girth ratios used in each measurement, actual coccygeal pressures of 122.8 ± 18.6/71.0 ± 13.4 mmHg were determined. The latter corresponded to values of 149.4 ± 19.0/97.6 ± 14.0 mmHg, when corrected to heart (shoulder) level. Normal limits (defined as within 2.5th and 97.5th percentiles) for all horses, regardless of class, were 80 to 144 mmHg/49 to 105 mmHg for coccygeal uncorrected values and 86 to 159 mmHg/45 to 97 mmHg adjusted for bladder width to tail girth ratio.  相似文献   

Biomechanical Evaluation of a Crimp Clamp System for Loop Fixation of Monofilament Nylon Leader Material Used for Stabilization of the Canine Stifle Joint   总被引：1，自引：0，他引：1  

C. COLLINS ANDERSON III  DVM    JAMES L. TOMLINSON DVM  MVSC  Diplomate ACVS    WILLIAM R. DALY DVM  Diplomate ACVS    WILLIAM L. CARSON PhD    JOHN T. PAYNE DVM  MS  Diplomate ACVS  COLETTE C. WAGNER-MANN DVM  PhD 《Veterinary surgery : VS》1998,27(6):533-539

Objective —To test a crimp clamp system designed to secure monofilament nylon leader (MNL) material commonly used as lateral fabellotibial sutures (LFS) in extra-articular stabilization of the canine stifle joint.
Study Design — In vitro biomechanical tests of MNL loops secured with either the crimp clamp system or knots were performed. Suture loops (n = 94) were created from 27.3 kg tensile strength MNL and fastened with knots or crimp clamps. Tests were conducted on steam-sterilized, ethylene-oxide-sterilized, and nonsterilized MNL sutures. Loops were evaluated in single load tests and cycled tests. Values for load to failure, initial loop tension, loop elongation, mode of failure, and point of failure were determined.
Results —Crimp-clamped loops were superior to knotted loops in all parameters tested in both cycled and noncycled tests. Loop failure generally occurred by breaking within 3 mm of the fixation in both clamped and knotted tests. Loop elongation after cycling was greater in the knotted loops compared with clamped loops ( P < .001). Load to failure was greater in clamped tests than in knotted tests (P < .001), regardless of sterilization technique used. Significantly higher initial loop tension could be achieved with the clamp system compared with knot fixation ( P < .001).
Conclusions —The crimp clamp system provides superior in vitro loop fixation characteristics compared with knot fixation in 27.3 kg test MNL.
Clinical Relevance —Based on the results of biomechanical testing and the known biocompatibility of the system's implant components, clinical trials using the crimp clamp system are warranted.  相似文献
