By use of a barometric technique, tidal volume (VT), minute volume (VE), respiratory frequency (f), and respiratory evaporative heat loss (Eex) were measured from conscious unrestrained potoroos (Potorous tridactylus), barred bandicoots (Perameles gunnii), and New Zealand white rabbits (Oryctolagus cuniculus) at temperatures in and above the thermoneutral zone (TNZ). Rectal temperature (Tre) and oxygen consumption were also measured. VT initially decreased with rising Ta, but in the potoroo and rabbit it then increased past the resting level. VE increased much more in the marsupials than in the rabbit, and higher Eex maxima were also found for the marsupials. The marsupials had high Q10's above the TNZ, and had a panting efficiency of 80%. The rabbits had a Q10 of 1.9 above the TNZ and 100% panting efficiency. The high VE and Eex and low panting efficiency of the marsupials may be due to their lower Tre which allows transfer of heat from the environment to the animal.

First Time

Enteroparasites can be pathogenic for the rabbit population and for this reason, we have investigated its occurrence in bioterium of rabbits. The sample group was composed of 103 adult males of the species Oryctolagus cuniculus and New Zealand breed. Fecal samples (n = 103) were processed using the Willis Techniques (Fluctuation in saturated sodium chloride solution with specific density of 1.20 g/mL) and Faust (Centrifugal-flotation in zinc sulphate with density of 1.18 g/ml). The diameters of larger and smaller sizes of the sporocysts and sporozoites of the coccidia were measured by means of optical microscopy using the program CellSens 1.17_00_en_Rhine_13Feb2017. The Faust Technique showed positivity of 39.74% (31/78) for Eimeria spp, while in Willis Technique, 35.90% (28/78) was observed for Eimeria spp, being the species Eimeria perforans and in 51.28% (47/78) of them there was no parasitism. We identified, for the first time, the occurrence of the specie E. perforans in rabbits of the species O. cuniculus, New Zealand breed kept in a bioterium. Therefore, it is extremely important for the implantation of parasitic control of rabbits kept in bioterium for scientific purposes, the monitoring of possible infections by means of periodic coproparasitological exams.

Rate Infusion

New Zealand white rabbits (Oryctolagus cuniculus) are an established in vivo model for the study of structural and functional consequences of vocal-fold vibration. Research design requires invasive laryngotracheal procedures, and the presence of laryngospasms or pain responses (or both) hinder phonation-related data collection. Published anesthesia regimens report respiratory depression and muscle tone changes and have been unsuccessful in mitigating autonomic laryngeal responses in our protocol. Infusion of ketamine hydrochloride and dexmedetomidine hydrochloride in pediatric medicine provides effective analgesia and sedation for laryngotracheal procedures including intubation and bronchoscopy; however, data evaluating the use of ketamine–dexmedetomidine infusion in rabbits are unavailable. This study reports a new infusion regimen, which was used in 58 male New Zealand white rabbits that underwent a nonsurvival laryngotracheal procedure to induce phonotraumatic vocal-fold injury. Animals were sedated by using ketamine hydrochloride (20 mg/kg IM) and dexmedetomidine (0.125 mg/kg IM). Maintenance anesthesia was provided by using continuous rate intravenous infusion of ketamine hydrochloride (343 μg/kg/min) and dexmedetomidine (1.60 μg/kg/min). A stable plane of anesthesia with no autonomic laryngeal response (laryngospasm) was achieved in 32 of the 58 rabbits (55%). Laryngospasms occurred in 25 of 58 animals (43%) and were controlled in 20 cases (80%) by providing 0.33 mL 2% topical lidocaine, incremental increase in infusion rate, or both. Continuous rate infusion of ketamine hydrochloride–dexmedetomidine with prophylactic topical lidocaine provides a predictable and adjustable surgical plane of anesthesia, with minimal confounding respiratory and autonomic laryngeal responses, during extended-duration laryngotracheal surgery in rabbits. This regimen should be considered as an alternative to injection maintenance for prolonged, invasive procedures.
