“…O Sapajus nigritus, popularmente conhecido como macaco-prego, é um dos mais abundantes espécimes de primatas do Brasil. Das medidas de controle populacional, a vasectomia, ou seja, a interrupção da patência dos ductos deferentes, pode ser empregada, pois mantém o comportamento de liderança do animal no grupo em que convive, por meio da presença hormonal, produção de células da série espermatogênica e cópula [6].…”

“…Para analgesia trans-operatória, empregou-se bloqueio do cordão espermático com lidocaína 2%, sem vasoconstritor, na dose de 2 mg/kg/cordão. A monitoração transoperatória foi realizada por meio de oximetria de pulso (SpO2), eletrocardiografia (ECG), pressão arterial sistólica (PAS) não-invasiva por oscilometria, termometria esofágica, capnografia (ETCO2) e analisador de gases com monitor multiparâmetros (LifeWindow LW-9) 6 .…”

Background:The black capuccin (Sapajus nigritus) is one of the most abundant primate specimens in Brazil. Among population control techniques, vasectomy can be used once it maintains the animal's leading behavior in the group through hormonal presence, production of spermatogenic series, and copula. However, due to their escape behavior, agitation, in addition to the impossibility of knowing the physiological state of these animals beforehand, their capture poses a considerable challenge. Thus, chemical restraint is indispensable and the use of effective and safe anesthetic protocols to animal integrity is of paramount importance. In this scenario, the present study aims to report the anesthesia of a black capuccin submitted to vasectomy. Case: A 1-year-old male, 1.1 kg monkey (Sapajus nigritus) was admitted at a Veterinary Hospital after being found on the ground in a natural reserve in the town of Assis Chateaubriand, in the west of Parana State. After clinical evaluation, the patient was submitted to vasectomy as a birth control method, before his return to the natural area, which presented overpopulation of the species. After preanesthetic examinations, the animal was considered healthy, and thus, premedicated with the combination of dexmedetomidine (10 μg/kg) and ketamine (10 mg/kg), intramuscularly. Anesthetic induction with propofol was performed to effect. Laringeal desensitization was achieved with 2% lidocaine (2 mg/kg), which allowed orotracheal intubation through direct visualization. Anesthesia was maintained with 1% isoflurane in a 0.5 oxygen fraction and spontaneous ventilation using a non-rebreathing circuit. The spermatic cord and the skin were desensitized with lidocaine (4 mg/kg). During the procedure, the animal was monitored for pulse oximetry, electrocardiogram, systolic blood pressure, body temperature, end tidal CO2 (ETCO2), and end tidal isoflurane. The animal also received 10 mL/ kg/h ringer lactate throughout anesthesia and 30 mg/kg ampiciline as prophylactic antibiotic. After the completion of the surgery, inhalation anesthesia was interrupted and the animal was allowed to wake up. Discussion: The combination of 10 μg/kg dexmedetomidine and 10 mg/kg ketamine caused intense muscle relaxation and short-term sedation, which lasted 15 min. Protocol was sufficient for veno puncture and pre-oxygenation, but doses should be increased for longer procedures. Although other authors reported physiologic alterations with higher doses of these drugs, such complications were not observed in the present case. The anesthetic induction was smooth, with no excitement or complications. Propofol was infused at 1 mg/10 s, and a total dose of 10 mg/kg was necessary for induction. This rapid infusion rate could have caused the increase in propofol total dose, as described elsewhere. Propofol and local lidocaine allowed orotracheal intubation with a 2.5 mm uncuffed neonatal tube. During surgery, analgesia was achieved with pre surgical local anesthetic and a single bolus of fentanyl during duct deferens manip...

Numerous diseases are carried and can be transmitted from the African buffalo (Syncerus caffer) to livestock. Therefore, buffaloes may only be moved with a special transport permit. Disease-free buffaloes are in demand amongst private game farmers. Current disease-free animals derive from a small genetic pool and hence there is a special interest in bringing new genetic material into the disease-free populations. Different breeding programs were developed in the past, which allow producing disease-free offspring from an infected herd. In this study epididymal sperm from 16 mature African buffalo bulls were frozen with Triladyl™ and AndroMed ® (both Minitüb, Germany) with or without the addition of bovine seminal plasma. Post-thaw motility, longevity and acrosomal integrity were compared by means of paired two-tailed t-tests. For both cryodiluents the post-thaw motility was mostly higher when no seminal plasma was added: no differences could be seen for the acrosomal integrity. Triladyl™ was superior to AndroMed ® in regards to total post-thaw motility. This study indicates that the use of bovine seminal plasma in a concentration of 10% is detrimental rather than beneficial in regards to the post-thaw motility. Triladyl™ rather than AndroMed ® should be used to freeze buffalo epididymal sperm, since it is superior in terms of post-thaw motility, even though the former, containing egg yolk, is not a defined medium and therefore lacks quality standards and carries a hygiene risk. Cette étude montre que l'utilisation decplasma séminal bovin à la concentration de 10% est plus nuisible que bénéfique en ce qui concerne la motilité post-congélation. Triladyl TM devrait être préféré à Andromed ® pour congeler le sperme épididymal de bison, puisqu'il est meilleur en ce qui concerne la motilité post-congélation, même s'il contient du jaune d'oeuf et n'est pas un milieu défini ( pas de standards de qualité), ce qui sous-entend un risque hygienique.
