The quantification of lipid and protein oxidation in stallion spermatozoa and seminal plasma: seasonal distinctions and correlations with DNA strand breaks, classical seminal parameters and stallion fertility. The goal of this work was to correlate oxidative stress caused by reactive oxygen species (ROS) and DNA damage with classic semen parameters in spermatozoa and seminal plasma of fertile and subfertile stallions. Oxidation was measured in both lipids and proteins, using the thiobarbituric acid reactive species (TBARS) assay and the DNPH carbonyl groups assay, respectively. Sperm DNA damage was monitored using the TUNEL assay. These parameters were monitored in samples obtained during the breeding and the non-breeding seasons. In general, fertile stallions showed better classical semen parameter...
Hypothermic storage of equine isolated hepatocytes. The aim of the study was to establish the optimal methods for hypothermic storage of equine isolated hepatocytes. Viability of equine isolated hepatocytes after hypothermic storage was dependent on the type of storage medium as well as on the cell density in the storage suspension and the preservation period. Hepatocytes stored at 4 degrees C in Hanks' Balanced Salt Solution (HBSS) and Williams' Medium E (WE) for 24 h showed very low viability, numerous cell membrane blebs, very low attachment rate (11.9 +/- 6.5% and 34.8 +/- 19.1%, respectively) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenylte...
Defocused CO2 laser on equine skin: a histological examination. No studies have been published on effects of treatment with a defocused beam carbon dioxide (CO2) laser on equine skin histology. A better understanding of this will help to define how lasers should be used, in order to reduce potential side effects. Objective: To describe the acute effects of different doses of defocused CO2 laser, ranging from therapeutic to surgical levels, on equine skin. Methods: Defocused CO2 laser was administered to the skin in the hamstrings (91 J/cm2), fetlock (137 J/cm2) and loin (450 J/cm2) areas of 13 Standardbred horses. The acute effects on skin histology were e...
Management of equine poisoning and envenomation. Acute poisoning and envenomation often represent a diagnostic and therapeutic challenge. Although identification ultimately may benefit the affected animal, treatment frequently must commence before an etiologic diagnosis is established. Therefore, the goals for the management of acutely intoxicated horses must be focused on emergency intervention and stabilization of the patient, prevention of further exposure, and aggressive decontamination. This article reviews the treatment steps that should be considered during the management of horses experiencing poisoning or envenomation.
Suitability of biocompost as a bedding material for stabled horses: respiratory hygiene and management practicalities. Bedding material in stables has an important influence on air hygiene and information on the suitability of biocompost and wood shavings is incomplete. Objective: To compare the suitability and benefit of biocompost and wood shavings as bedding in horse stables and to determine key air factors for the evaluation of the potential impact of these materials on respiratory health. Methods: The study was conducted in a naturally ventilated stable with 4 horses. Air hygiene parameters were measured 24 h/day for 7 days with each bedding type: ammonia (NH3), inhalable and respirable dust, endotoxins, ...
Flood injury in horses. There is no way to prepare for every situation that arises in a disaster. By working closely with other producers and agricultural leaders, however, horse owners can lessen the impact of a disaster on their operation. Preparation and detailed planning are the most important aspects of flood-related injury prevention. Encouraging animal owners and caretakers to have an evacuation plan and dispersing knowledge about local and regional disaster authorities are critical for a successful disaster response. Educational programs on future disaster response empower communities to care for their people...
Field fracture management. Emergency management of distal limb and skull fractures in horses is vital to the successful outcome of these cases. Distal limb fractures, in particular, require careful assessment and counseling of the owner as well as adequate stabilization or coaptation of the fracture. Horses with limb or skull fractures may also have concurrent pain, blood loss, and other fluid losses that can result in shock requiring fluid therapy before definitive treatment of the fracture. Proper emergency fracture stabilization, initial treatment in the field, and patient transport are discussed.
Composition, physiochemical properties, nitrogen fraction distribution, and amino acid profile of donkey milk. This study investigated the changes in chemical composition, nitrogen fraction distribution, and AA profile of milk samples obtained during lactation from the Jiangyue breed of donkey in Northwest China. Results showed that donkey milk contained 9.53% total solids, 1.57% protein, 1.16% fat, 6.33% lactose, and 0.4% ash on average, which is more similar to mare and human milk than to the milk of other mammals. Throughout the lactation investigated, pH and density were constant, protein and ash content showed an apparent negative trend (an increase in lactose content during 120 d postpartum, foll...
A case of multiple epitrichial sweat gland ductal carcinomas in a horse. This case report describes a rare epitrichial sweat gland ductal carcinoma in a 14-year-old horse and is the first report of multiple carcinomas of this type in horses. Although several tumours developed, mostly on the distal extremities, over a 2-year period, the horse remained otherwise healthy. Topical treatment with imiquimod was successful for many of them.
Effect of initial cumulus morphology on meiotic dynamic and status of mitochondria in horse oocytes during IVM. The aim of this investigation was to examine the chromatin configuration of the nucleus, pattern of mitochondrial aggregation and mitochondrial activity in parallel studies in the same horse oocytes. Horse oocytes recovered by ultrasound-guided follicle aspiration in vivo were classified according to two main initial cumulus morphologies as having compact or expanded cumulus. The percentage of oocytes with a diplotene meiotic configuration at the time of recovery from the follicles was highest in compact oocytes. Oocytes with expanded cumulus layers at the time of recovery matured more rapidly...
A field study on the efficacy of doramectin against strongyles and its egg reappearance period in horses. The aim of the present study was to determine the efficacy and the so-called "egg reappearance period" (ERP) of doramectin in horses naturally infected with strongyles during a period of 34 weeks. A group of yearlings of 10 animals was treated intramuscularly with doramectin at a dose rate of 0.2 mg/kg bodyweight (BW) at the begin of the grazing season. To obtain comparable data, another group of yearlings (n = 10) was treated orally with ivermectin at a dose rate of 0.2 mg/kg BW. Individual faecal samples were examined for strongyle egg counts per gram of faeces (EPG) in two-week intervals. T...
[Intersexuality in horses]. Intersexuality is a rare congenital anomaly of horses. Diagnosis of intersexuality is difficult because there are usually no specific changes in the reproductive tract visible. During a period of five years, ten patients with reduced fertility or suspected intersexuality respectively were investigated using cytogenetic, molecular genetic, histopathological and endocrinological methods. In one case a 64,XX/63,X0 mosaicism was found. In six cases male pseudohermaphroditism was verified. These patients showed a male karyotype, testes and rudimentary parts of a female reproductive tract were prese...
Characterization of multidrug resistant Salmonella recovered from diseased animals. Three hundred and eighty Salmonella isolates recovered from animal diagnostic samples obtained from four state veterinary diagnostic laboratories (AZ, NC, MO, and TN) between 2002 and 2003 were tested for antimicrobial susceptibilities and further characterized for bla(CMY) beta-lactamase genes, class 1 integrons and genetic relatedness using PFGE. Forty-seven serovars were identified, the most common being S. Typhimurium (26%), S. Heidelberg (9%), S, Dublin (8%), S. Newport (8%), S. Derby (7%), and S. Choleraesuis (7%). Three hundred and thirteen (82%) isolates were resistant to at least one ...
Canadian veterinarians’ use of analgesics in cattle, pigs, and horses in 2004 and 2005. Anecdotal evidence suggests that many veterinarians may not use analgesics in livestock for routine surgical procedures or painful disease states. To investigate this, we conducted a national mail survey of a random sample of 1431 Canadian veterinarians (response rate, 50.1%). Questions primarily concerned veterinarians' analgesic usage for common surgeries and medical conditions in beef and dairy cattle, pigs, and horses, and attitudes toward pain management. More than 90% of veterinarians used analgesic drugs for equine surgeries, for cesarean section in sows and cows, and for bovine claw am...

Equine learning behaviour. Scientists and equestrians continually seek to achieve a clearer understanding of equine learning behaviour and its implications for training. Behavioural and learning processes in the horse are likely to influence not only equine athletic success but also the usefulness of the horse as a domesticated species. However given the status and commercial importance of the animal, equine learning behaviour has received only limited investigation. Indeed most experimental studies on equine cognitive function to date have addressed behaviour, learning and conceptualization processes at a moderately ba...
Effects of buprenorphine on nociception and spontaneous locomotor activity in horses. To investigate spontaneous locomotor activity (SLA) and antinociceptive effects of buprenorphine in horses. Methods: 6 healthy adult horses. Methods: Horses received each of 3 treatments (10 mL of saline [0.9% NaCl] solution, 5 microg of buprenorphine/kg, or 10 microg of buprenorphine/kg). Treatments were administered IV. Order of treatments was randomized, and there was a 10-day interval between subsequent treatments. Spontaneous locomotor activity was investigated in a behavioral box by use of infrared photoelectric sensors connected to a computer, which detected movement of each horse. Anti...
