13281. Perineal analgesia and hemodynamic effects of the epidural administration of meperidine or hyperbaric bupivacaine in conscious horses - DeRossi, Rafael; Sampaio, Breno F.B.; Varela, Juliana V.; Junqueira, Alexandre L.
Epidural administration of bupivacaine and meperidine produces analgesia in several animal species and in humans. A prospective randomized study was conducted in 18 healthy horses to compare the effect of these 2 drugs administered by the epidural route. Animals were divided into 3 treatment groups of 6 animals each. All drugs were injected by the epidural route in all animals between the 1st and 2nd coccygeal vertebrae. Treatment 1 (BUP) — 0.06 mg/kg of body weight of 0.5% hyperbaric bupivacaine; treatment 2 (MEP) — 0.6 mg/kg of body weight of 5% meperidine; treatment 3 (SS) — 0.9% saline solution (control...

13282. A comparison of electroejaculation and epididymal sperm collection techniques in stallions - Cary, Julie A.; Madill, Scott; Farnsworth, Kelly; Hayna, Justin T.; Duoos, Lisa; Fahning, Mel L.
The purpose of this study was to evaluate 2 methods of semen collection that could be used as terminal procedures in stallions with irreparable conditions, such as fractures or colic. Electroejaculation was attempted under general anesthesia. Forty-eight hours later, the ponies were castrated and 2 different epididymal sperm collection techniques were attempted by using a flushing or floating method. Additionally, the effect of supplemental seminal plasma was evaluated. Experimentally, electroejaculation was found to be a safe but ineffective method of terminal semen collection. Viable sperm cells were successfully recovered with both types of epididymal collection. The flotation method was least...

13283. Learning from outbreaks of bovine tuberculosis near Riding Mountain National Park: Applications to a foreign animal disease outbreak - Lees, V. Wayne
Riding Mountain National Park, Manitoba, is home to a population of free-roaming elk (Cervus elaphus manitobensis) that have been found to be infected with Mycobacterium bovis, the agent of bovine tuberculosis (TB). The disease has also been found in a number of cattle herds near the Park and, as a result, Manitoba has been assigned a split status for bovine TB. A number of government agencies, with input from representatives from the wildlife and agricultural sectors, have responded by devising a program to detect, investigate, control, eradicate, and prevent TB in both wild and domestic animals. Experience from these efforts...

13284. Feline urethral plugs and bladder uroliths: A review of 5484 submissions 1998–2003 - Houston, Doreen M.; Moore, Andrew E.P.; Favrin, Michael G.; Hoff, Brent
The results of 5484 submissions from cats to the Canadian Veterinary Urolith Centre between February 1998 and February 2003 are presented. Of the submissions, 618 were urethral plugs and 4866 were bladder uroliths. The majority of the urethral plugs were from male domestic shorthair and longhair cats. Approximately 50% of the urolith submissions were oxalate, 44% were struvite. Oxalate uroliths were the most common mineral type in males and in Himalayan, Persian, and Siamese cats. Struvite uroliths were the most common mineral type in domestic shorthair and longhair cats. Females outnumbered males by 1.4:1 in struvite urolith submissions. A review...

13290. Diabetes mellitus in a 6-month-old Charolais heifer calf - Clark, Zoe
This unthrifty heifer calf was thin, weak and had a dull haircoat. Urinalysis and blood work revealed glycosuria, ketonuria, hypoproteinemia, and hyperglycemia. Euthanasia and necropsy were performed, revealing multifocal intersitial lymphocytic infiltration, an absence of islet cells, and a positive stain for bovine viral diarrhea virus in the pancreas.

13291. Pancreatic insulin-secreting neoplasia in a 9-year-old Afghan hound - Fenton, Anita C.
An Afghan hound was presented with recurring episodes of weakness progressing to seizures after exercise. Insulinoma was diagnosed by demonstrating excessive insulin secretion in the presence of hypoglycemia. A pancreatic mass was identified and removed during an exploratory laparotomy. Surgical and pathological findings, diagnosis, and clinical management are discussed.

13292. Electrocardiographic evolution in cats from birth to 30 days of age - Lourenço, Maria Lucia Gomes; Ferreira, Helena
Further knowledge of feline physiology and neonatology is needed because the number of cats being kept as pets and used as experimental animals has increased. Few studies have been published on feline sequential electrocardiography. This study was conducted to determine the values of normal waves, complexes, and intervals of the electrocardiogram in clinically healthy feline neonates. Serial electrocardiography was performed in 15 female and 15 male neonates at 30 days of age. Parameters analyzed were heart rate and rhythm, duration and amplitude of electrocardiographic waves, duration of intervals, and the electrical axis of the heart. The results did not show...

13294. Health status and risk factors associated with failure of passive transfer of immunity in newborn beef calves in Québec - Filteau, Virginie; Bouchard, Émile; Fecteau, Gilles; Dutil, Lucie; DuTremblay, Denis
Risk factors associated with failure of passive transfer of immunity (FPT) were evaluated among newborn beef calves in Québec. Physical examination was performed on calves born of a normal calving and blood samples were collected for determination of health status and measurement of serum concentration of immunoglobulin (Ig) G1. Of 225 calves, from 45 herds, 19 % showed FPT (serum IgG1 concentration < 10.0 g/L). Calves born in a stanchion-stall were more likely to show FPT (OR: 10.2). Calves bottle-fed colostrum were less at risk for FPT (OR: 0.06). Calf gender, month of birth, dam parity, and dam body condition...

13295. Survey of the status of copper, interacting minerals, and vitamin E levels in the livers of sheep in Ontario - Menzies, Paula I.; Boermans, Herman; Hoff, Brent; Durzi, Tiffany; Langs, Lisa
Livers from cull ewes and market lambs raised in Ontario were obtained to determine the status of specific minerals and vitamin E. Values for copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) obtained by atomic absorption and inductively coupled plasma — atomic emission spectroscopy (ICP-AES) were found to be statistically different but sufficiently biologically similar to allow the use of ICP-AES for screening groups of samples for deficient or toxic levels of those minerals. Toxic levels of cadmium were not found. Toxic levels of aluminum were found in 1 cull ewe and 1 market lamb. A significant proportion of...

13297. A review of the physiological effects of ?2-agonists related to the clinical use of medetomidine in small animal practice - Sinclair, Melissa D.
Medetomidine is a relatively new sedative analgesic drug that is approved for use in dogs in Canada. It is the most potent ?2-adrenoreceptor available for clinical use in veterinary medicine and stimulates receptors centrally to produce dose-dependent sedation and analgesia. Significant dose sparing properties occur when medetomidine is combined with other anesthetic agents correlating with the high affinity of this drug to the ?2-adrenoreceptor. Hypoventilation occurs with medetomidine sedation in dogs; however, respiratory depression becomes most significant when given in combination with other sedative or injectable agents. The typical negative cardiovascular effects produced with other ?2-agonists (bradycardia, bradyarrhythmias, a reduction...
