BACKGROUND: Downer cow syndrome (DCS) is often diagnosed in dairy cattle during the early post-partum period. The etiology of this condition is not completely understood, as it can be related to the energetic or electrolyte metabolism, as well as to infectious diseases or to trauma. HYPOTHESIS/OBJECTIVES: The aim of this study is to compare energy metabolism and insulin sensitivity indices and various biochemical parameters between recumbent and healthy dairy cows. ANIMALS: A prospective study has been undertaken on 361 recumbent and 80 healthy Holstein cows. METHODS: Plasmatic glucose, insulin, non-esterified fatty acid (NEFA) and β-hydroxybutyrate (BHB) were assayed in all cows in order to calculate the insulin sensitivity indices but also minerals (Calcium, Phosphorous and Magnesium), thyroxin and creatine kinase. Body Condition Scores (BCS) was assessed. RESULTS: Significant differences in NEFA, and the glucose and insulin sensitivity indices ("Homeostasis Model Assessment" HOMA, "Revised Quantitative Insulin Sensitivity Check Index" RQUICKI, RQUICKI-BHB) were observed between healthy and recumbent cows in the early post-parturient period indicating disturbances of glucose and insulin homeostasis in the recumbent cows. In the same manner, mineral concentrations were significantly different between healthy and recumbent cows. Glucose, insulin NEFA, and HOMA, were different between early post-partum downer cows and the DCS-affected cows later in lactation. CONCLUSION AND CLINICAL IMPORTANCE: Results indicate disturbances in energy homeostasis in DCS-affected dairy cows. Further research should determine a prognostic value of the indices in cows suffering from recumbency of metabolic origin [less ▲]

Introduction: The aim of this study was to establish echocardiographic reference values for the equine species using allometric regression equations based on body weight (BW) and thoracic circumference (TC). Animals: A total of 239 horses or ponies were studied, including 65 warmbloods, 33 Standardbreds, 41 Thoroughbreds, 32 Arabian horses, 28 draft horses and 40 ponies aged from 1 day to 30 years, weighing from 18 to 890 kg, with no evidence of cardiac disease. Methods: For each horse or pony, a two-dimensional and M-mode echocardiography was performed. Within each breed, the relationships between BW or TC and echocardiographic dimensions were examined using power regression equations. Predictions and their 95% prediction intervals were calculated for the echocardiographic measurements. Results: Within each breed, all echocardiographic measurements showed a significant and positive relationship with a high coefficient of determination for the estimation of the regression equations using BW and TC as the main explanatory variables. Breed-specific power regression equations as well as the 95% prediction intervals were calculated for each echocardiographic measurement as a function of BW and TC. Conclusions: In the future, the body size-corrected and breed-specific echocardiographic reference values calculated in the present study could be used to discriminate between normal and abnormal values in a given animal.

This study was undertaken to assess the suitability of fentanyl/fluanisone (‘Hypnorm’, VetaPharma; 0.315 mg/mL of fentanyl citrate and 10 mg/mL of fluanisone) alone or combined with midazolam in rhesus macaques. Fifteen rhesus macaques requiring sedation for veterinary procedures received an intramuscular (IM) dose range of Hypnorm from 0.01 mL/kg to 0.3 mL/kg either alone or combined with 0.5 mg/kg of mid- azolam. To reverse the sedation, flumazenil in combination with either naloxone, buprenorphine or butor- phanol was administered intravenously (IV) or IM. Rhesus macaques were successfully sedated with 0.1 mL/kg of Hypnorm and 0.5 mg/kg of midazolam, and sedation was partially reversed by the administration of flumazenil and either naloxone or buprenorphine. However the primates remained slightly sedated and were only released into their home cage several hours post recovery. Butorphanol failed to induce recovery and caused marked respiratory depression. The neuroleptanalgesic combination, Hypnorm and midazolam, effectively immobilized rhesus macaques and was reversible with a combination of flumazenil and either naloxone or buprenorphine. [less ▲]

Bone marrow and adipose tissue represent the two most commonly exploited sources of adult mesenchymal stem cells for musculoskeletal applications. Unfortunately the sampling of bone marrow and fat tissue is invasive and does not always lead to a sufficient number of cells. The present study describes a novel sampling method based on microbiopsy of skeletal muscle in man, pigs, dogs and horses. The process includes explant of the sample, Percoll density gradient for isolation and subsequent culture of the cells. We further characterized the cells and identified their clonogenic and immunomodulatory capacities, their immune-phenotyping behavior and their capability to differentiate into chondroblasts, osteoblasts and adipocytes. In conclusion, this report describes a novel and easy-to-use technique of skeletal muscle-derived mesenchymal stem cell harvest, culture, characterization. This technique is transposable to a multitude of different animal species. [less ▲]

Volatile agents for anaesthesia are widely used for anaesthetizing laboratory primates, and isoflurane is one of the most frequently used agents. Sevoflurane has been shown to offer a more rapid recovery than iso- flurane in a number of species, but no comparisons have been made in non-human primates. This study compared the recovery characteristics of isoflurane and sevoflurane in rhesus macaques undergoing experi- mental neurosurgery. Twelve primates (7 males and 5 females) were randomly allocated to the treatment groups. They were sedated with ketamine (10 mg/kg) and anaesthesia was induced with propofol (usually 8 mg/kg intravenously [IV]). Anaesthesia was maintained with either sevoflurane (SEVO) (2.2 0.4%) or iso- flurane (ISO) (1.2 0.2%) and alfentanil (0.2–0.5 mg/kg/min IV) for 332–592 min. Animals were mechanically ventilated. Meloxicam (0.3mg/kg) and methylprednisolone infusion (5.4mg/kg/h) were also administered. Time to extubation after cessation of anaesthesia was significantly shorter with sevoflurane (ISO: 7.0 1.8 min; SEVO: 3.6 1.5; *P 1⁄4 0.005) as was the time to the animal sitting unaided (ISO: 15.7 8.2 min; SEVO: 7.1 1.7min; *P1⁄40.004). No significant difference in the quality of recovery following isoflurane or sevoflurane anaesthesia was found. In conclusion, isoflurane and sevoflurane are both suitable volatile agents for the maintenance of general anaesthesia in rhesus macaques undergoing experimental neurosur- gical procedures. The two volatile agents presented a similar emergence quality profile, however sevoflurane anaesthesia was associated with a faster recovery, offering the possibility of conducting earlier post-operative neurological assessment.

A six-month-old alpaca was presented to the veterinary teaching hospital of the University of Liège (Belgium) with a bilateral cataract. A decision was made to perform bilateral cataract surgery after an ocular ultrasound and electroretinogram were performed to assess the posterior segment and retinal function, respectively. As a premedication, the alpaca received xylazine, butorphanol and midazolam intramuscularly. Anaesthesia was induced subsequently with ketamine and midazolam intravenously and maintained with isoflurane on oxygen/air mixture. The alpaca was mechanically ventilated during surgery. Neuromuscular blockade was induced and maintained with cis-atracurium intravenously. The dose of cis-atracurium was permanently adapted using a peripheral nerve stimulator. This case report brings new knowledge regarding the use and dosage of cis-atracurium in alpacas. [less ▲]

Introduction/Purpose: Pre-clinical randomized controlled animal trials have been conducted to evaluate the effects of mesenchymal stem cell (MSCs) transplantation on intervertebral disc (IVD) degeneration. According to their histological results and to imaging assessment of the IVD, intradiscal injection of MSCs is effective, arresting or slowing IVDD process, and is associated with a low complication rate. Few of these studies have been conducted on canine artificially degenerated IVD, using bone marrow or adipose-derived MSCs. Therefore a systematic study on naturally degenerated IVD using MSCs obtained from autologous muscular tissue in dogs is still lacking. The aims of this study were to evaluate the clinical effects of intradiscal injection of muscle-derived MSCs and its effects on imaging features of the intervertebral disc. Methods: Eight experimental dogs were randomly included with the approval of the University’s Animal Care and Use Committee. The final inclusion criteria were the presence of naturally degenerated lumbosacral IVD detected on low-field magnetic resonance (MRI) images and the obtaining of 3 x 106 autologous muscle-derived MSCs. A computed tomography (CT) and MRI examination was performed before and 2 months after the procedure and 13 imaging parameters were assessed. Mesenchymal stem cells diluted in 0,2 ml of FRS Hypothermosol were injected in the lumbosacral IVD under CT-guidance. Clinical examinations were performed regularly during 1 month after the procedure. Results: Six dogs met the inclusion criteria. The remaining 2 dogs did not undergo intradiscal injections, but were used as control group. No major or minor complications were reported during the procedure. No abnormalities were noticed during the clinical examinations. No statistically significant variations of IVD imaging features were noticed before and after the injections. Discussion/Conclusions: Intradiscal injection of muscle-derived MSCs is clinically safe and it is not associated with any progression of the IVD degeneration, detected by CT or low-field MRI imaging. Further studies are needed to assess its efficacy as treatment for the canine natural IVD degeneration. [less ▲]

During the initial stages of training of young Thoroughbred horses, low intensity exercise is employed to increase aerobic capacity. High Resolution Respirometry (HRR) allows the determination of aerobic capacities in small samples of permeabilised muscle fibres. The aim of the study was to measure the mitochondrial function by HRR in Thoroughbred horses, to compare these values to Warmblood horses and to evaluate the effect of a 10-weeks training period. The mitochondrial function was measured by HRR using different substrate-uncoupler protocols (SUIT 1 and 2) in muscle microbiopsies from two groups of untrained horses: 17 Warmblood and 8 Thoroughbred and in the group of 8 Thoroughbred horses before and after a 10-week training period. The SUIT1 protocol employed to compare the two groups of horses showed that in Thoroughbred horses, the mean values for oxygen flux expressed as tissue mass-specific respiration were significantly higher for complex I (CI)Glutamate+Malate, CI + complex II, and maximum electron transport capacities (ETSmax) than the mean values measured in Warmblood horses. The SUIT 1 and SUIT 2 protocols revealed large differences among Thoroughbred horses before and after training. The SUIT 2 protocols showed a significant difference for the complex I activity before and after training but only when the oxygen flux was expressed as percentage of ETSmax. This study shows the interest of HRR in equine sport medicine and exercise physiology, but shows that the technique requires further refinement. Indeed significant differences have been shown between the Thoroughbred and the Warmblood horses highlighting the need to have baseline data for each breed. The Thoroughbred horses had globally a high oxidative phosphorylation capacity with an increase of CI activity induced by an aerobic training program. [less ▲]
