AbstractThis study aimed to evaluate the beaks of three species of birds using radiography and computed tomography (CT). The mean lengths of maxillary and mandibular rostra on radiographs were highest for toco toucan, followed by buff‐necked ibis, and least for red‐legged seriema birds. The height and width of maxillary and mandibular rostra measured on CT had mean values highest for toco toucans, followed by red‐legged seriema, and least for buff‐necked ibis. Except for the proximal region of the maxillary rostrum, the HU values were positive for other regions of the maxillary and mandibular rostra in the buff‐necked ibis and red‐legged seriema and negative in all for the toco toucan.

AbstractA free‐ranging adult, 1.59‐kg, female orange‐spined hairy dwarf porcupine (Sphiggurus villosus) was presented due to inability to locomotion. Ventrodorsal and lateral radiographs of the pelvis showed craniodorsal luxation of the right hip joint, and ischial fracture on the left side. Femoral head and neck ostectomy was performed, but the lesser trochanter was preserved. At the final evaluation, 2 months after the surgery, the porcupine showed full weight‐bearing on the right hindlimb, with no signs of lameness. Range of motion of the hip joints showed a decrease in the right hip joint, but crepitation was not observed in palpation. On radiographs, no bony proliferation was seen along the osteotomy line or in the area of the lesser trochanter, and the right and left trochanter were on the same level. The animal was released back into its natural habitat.

AbstractThis study aimed to evaluate radiographic and sonographic features, and histogram parameters based on grayscale ultrasound of the liver and spleen in healthy toco toucans. Fifteen adult toco toucans (Ramphastos toco), seven females and eight males, weighing approximately 650 g, were enrolled in the study. On the right lateral radiographic view, the liver was visualized in the midventral region of the coelomic cavity; ultrasonographically, the liver was located in the middle portion of the coelomic cavity in close relationship to the heart, and thoracic and abdominal air sacs. Two hepatic lobes were identified; the right lobe was larger than the left one. The spleen was visualized in 10 toco toucans on radiographs and only in eight toucans on ultrasound exams. The gallbladder was identified only on ultrasound. On the right lateral radiographic view, the spleen was visualized dorsal to the proventriculus and ventral to the lungs/air sacs as an oval shape. Ultrasonographically, the spleen was observed caudal to the liver, cranial to the proventriculus and craniodorsal to the ventriculus. There was no significant difference in spleen length for either radiographic or ultrasound measurements. The brightness intensity (BI) for mean gray level (G) and standard deviation of gray levels (SG) in the liver were 101.315 (± 16.170) and 12.453 (± 2.616), respectively. Mean G and SG levels in the spleen were 63.940 (± 18.321) and 7.494 (± 3.595), respectively. In conclusion, the sonographic features and histogram parameters indicated that the liver is more echogenic and heterogeneous than the spleen, which must be considered for diagnosing alterations in these organs.

AbstractThis study aimed to assess the sonographic features of abdominal organs in healthy captive Neotropical otters (Lontra longicaudis). The sonograph showed that the urinary bladder was located in the caudal abdomen and its content was uniformly anechoic. The bladder wall had three layers: outer hyperechoic serosa, hypoechoic muscular layer and hyperechoic mucosa. The mean total wall thickness was 0.10 cm. The splenic parenchyma had a homogeneous echotexture with greater echogenicity than that of the left renal cortex and liver. The borders were regular and tapered. Rugal folds were observed in the stomach when undistended. The mean gastric wall thickness was 0.28 cm and five distinct layers were visible. The liver had smooth contours, and division of the hepatic lobes was not precisely visualized. The hepatic parenchyma had a homogeneous echotexture with greater echogenicity as compared to the right kidney and lesser echogenicity than that of the spleen. The gallbladder appeared as an oval or rounded structure in the transverse plane, filled with homogeneous anechogenic content; the wall was thin, regular and hyperechoic, with a mean thickness of 0.09 cm. The kidneys had a lobulated appearance with renicular subunits. The mean total length of the kidneys in longitudinal plane was 6.18 cm for the left and 6.27 cm for the right. Each reniculus was covered by an echogenic capsule, and the medullary region was more hypoechogenic than the cortical region. In conclusion, sonographic features in most of the abdominal organs in Neotropical otters are similar to the ultrasound patterns observed in healthy dogs and cats, except for kidneys with reniculi.

AbstractThis study aimed to describe sonographic features of the liver, gallbladder and hepatic histogram from grey‐scale ultrasound in three species of healthy non‐venomous snakes. Twenty‐eight adult snakes were enrolled in the study, including 10 common boas (Boa constrictor), eight black‐tailed pythons (Python molurus) and 10 rainbow boas (Epicrates crassus). The snakes fasted for 30 days and were manually restrained while conscious. For B. constrictor and P. molurus the liver and gallbladder were best visualized in ventral recumbency, and E. crassus in dorsal recumbency. A single elongated hepatic lobe was identified in all snakes. The gallbladder was positioned caudal and separated from the liver, with an oval shape and homogeneous anechoic content in the lumen, and thin and regular walls. A region of interest by pixel number was chosen for the liver, fat bodies, left kidney, and splenopancreas. The mean grey level (G) of the organs had significant differences within each species. Standard deviation of grey levels (SG) had significant differences within B. constrictor and E. crassus. P. molurus had no significant difference among organs. The comparison among snakes showed that E. crassus had G of liver and splenopancreas lower than B. constrictor and P. molurus. The SG of the liver in E. crassus was lowest compared to B. constrictor and P. molurus. P. molurus showed the highest values in mean of G and SG. In conclusion, despite the liver and gallbladder having similar sonographic features, the grey‐level histogram showed that liver echotexture and echogenicity differ among species.

AbstractThe present study aimed to determine references of normality of computed tomographic (CT) images of mandibular and parotid salivary glands (PSGs), medial retropharyngeal and mandibular lymph nodes and thyroid gland of 10 clinically healthy crab‐eating foxes, Cerdocyon thous. The location, shape, homogeneity of the parenchyma, and length, height, width and pre‐ and post‐contrast attenuation values were evaluated. The anatomical structures in the crab‐eating foxes studied here presented anatomical landmarks similar to those described for domestic dogs, and showed a regular shape and homogenous parenchyma, except for the PSGs, that showed predominantly heterogeneous parenchyma. The thyroid gland topography in the crab‐eating fox, though very similar, is not identical to the domestic dog and the presence of isthmus between the lobes was not detected. The values obtained from crab‐eating foxes are within the normal range, although in the upper limits of dogs. There was a significant difference in the attenuation values between the right and left lobes of the thyroid gland, being greater in the left thyroid lobe. CT attenuation values ranges for this neotropical canid can be incorporated into routine staging procedures in the veterinary care of the crab‐eating foxes. Furthermore, the CT images obtained were similar to those of healthy dogs, and the information obtained can be considered as initial tomographic references of normality in the cervical structures of the crab‐eating fox, in order to aid in the diagnosis of future diseases that can affect this neotropical canid.

This pilot study aimed to evaluate the long-term effects of Whole-Body Vibration (WBV) on hind limb muscles, gait and pain in lame dogs with borderline-to-severe hip dysplasia. Ten lame client-owned dogs with borderline-to-severe hip dysplasia, aged from 1.5 to 9.0 years and weighing 14.5 to 53.0 kg, were enrolled. The WBV training program consisted of 15 min sessions three times weekly for 16 weeks. Muscles of the hind limbs were evaluated using measurements of thigh circumference, the cross-sectional thickness of selected hind limb muscles by ultrasound assessment, and vastus lateralis muscle activity determined by surface electromyography (EMG). Lameness and clinical signs of pain were assessed by visual lameness scoring, orthopedic examination and an owner-based questionnaire. Kinetic analysis was performed by using a pressure-sensitive walkway. Manual thigh circumference measurements of both hind limbs showed significant increases over the trial period with a greater degree of change observed after week 8. Ultrasound measurements of the left gluteal muscles and the quadriceps femoris muscles of both hind limbs showed significant increases in the cross-section thickness post WBV. Owner’s perception of pain also showed a decrease in signs of pain at week 12 and week 16 compared to baseline. Based on graphs of the EMG activity patterns of the vastus lateralis muscle, 65% of the hind limbs had an improvement after 48 WBV sessions when compared to pre-session patterns. However, no significant differences were observed in visual lameness evaluation and kinetic analysis. Therefore, further studies will help to better clarify the role of WBV in canine rehabilitation protocols.

AbstractBackgroundRadiographic measurements are a useful tool to assess skeletal health and development in primates. This study aimed to perform radiographic measurements of hind limbs in capuchin monkeys.MethodsTwelve Sapajus spp. were used; ten adults and two sub‐adults, nine females and three males.Results and conclusionsThe pelvimetry showed that the pelvic inlet area presented mean values of 7.63, 10.23, and 5.43 cm2 for adult males, adult females, and sub‐adult females, respectively. The mean inclination angle was 129.45° and the mean values for the mechanical lateral proximal and distal femoral angles were 102.32° and 90.93°, respectively. The mean values for the anatomic lateral proximal and distal femoral angles were 104.59° and 85.98°, respectively. In conclusion, the radiographic measurements proved feasible for hind limb evaluation in Sapajus spp. and can be used for comparison with animals presenting orthopedic lesions.

AbstractThe giant anteater (Myrmecophaga tridactyla) is the largest of the Neotropical vermilinguans. This animal is the second mammal most frequently run over on the roads of Cerrado biome, Brazil. Therefore, it is pivotal to know the anatomy of this species to contribute to the clinical care of these animals. Thus, the aim of this study was to identify the anatomical structures in the abdominal region of the giant anteater using computed tomography (CT). For this, the tomographic analysis was performed in sequential order in the craniocaudal direction in five giant anteaters. Moreover, four giant anteater corpses were used for anatomical studies, where two corpses were sectioned in cross sections of approximately 3 cm each, and two animals were dissected to identify the abdominal organs. The association between CT and anatomical study allowed the visualization of anatomical structures found in the abdominal cavity, such as the topographic anatomy facilitates the identification of organs on CT images. The findings of this study demonstrated that CT is a good technique to provide detailed information about the anatomical structures in the abdominal cavity and that this study can be used as CT and anatomical reference for veterinarians who care for wild animals.

Background Ligamentum teres (LT) has traditionally been considered a vestigial or redundant structure in humans; however, based on new studies and the evolution of hip arthroscopy, the LT injury has been viewed as a source of hip pain. Therefore, LT reconstruction can be beneficial in some cases. Rabbits have been frequently used as a model for cranial cruciate ligament reconstruction but few studies are available for ligamentum teres reconstruction. Objective To evaluate the semitendinosus tendon to replace ligamentum teres with the toggle technique, using rabbits as an experimental model. Methods Twenty-six female Norfolk rabbits with approximately 3 months of age were divided into two equal groups after excision of ligamentum teres (LT) from the right hip joint: G1—no reconstruction of LT and capsulorrhaphy; G2—double—bundle reconstruction of the LT using semitendinosus tendon autograft. In both groups, the LT was removed from the right hip joint. In G2 the autograft was harvested from the left hind limb of the same rabbit. The rabbits were evaluated clinically at different time intervals; before surgery (M1), 48 h (M2), 15 days (M3), 30 days (M4) and 90 days (M5) after surgery. Results The rabbits supported their limbs on the ground in both the groups. As complications of the procedure, four hip joints showed subluxations in the radiographic evaluation of G1; three at M4 and one at M5. In G2; two luxations of hip joints at M3 and one subluxation at M4 were seen. On ultrasound, irregular articular surface was seen in 30.8% of the rabbits that had subluxation of hip joints. Gross evaluation identified tendon graft integrity in 76.92% of the rabbits. Histological analysis revealed graft adhesion to the bone in the early phase comprised of sharpey-like collagen fibers. Conclusion The double-bundle reconstruction of the LT using autologous semitendinosus tendon associated with the toggle rod shows an early phase of tendon graft ligamentization at 90 days post-operatively in young rabbits, but biomechanical bias suffered by the tendon during gait must be considered.

AbstractAn approximately 5‐month‐old, male puma (Puma concolor) was rescued after being hit by a vehicle on a highway. Radiographic examination revealed caudal endplate fracture of L6 and fissure of the vertebral arch with articular facet involvement. Conservative treatment was considered the most appropriate option due to the clinical signs, location and fracture type. The animal was confined in an enclosure that allowed limited mobility. On the 35th day after admission, a new radiographic exam showed signs similar to osteomyelitis. A 30‐day treatment with amoxicillin‐clavulanate was successful in resolving the suspected infection. At the same time, environmental enrichment was carried out by feeding living prey, which allowed the puma to be released into its natural habitat on the 79th day after admission.

AbstractBackgroundCholelithiasis is a digestive system disorder of multifactorial origin that occurs due to stones formed in the gallbladder. This study aimed at investigating by abdominal ultrasound examination the prevalence of cholelithiasis in lion tamarins kept under human care.MethodsThirty lion tamarins from five Brazilian zoos, including 17 golden lion tamarins and 13 golden‐headed lion tamarins, were evaluated.ResultsConsidering all lion tamarins, the overall frequency of cholelithiasis was 53.3% (16/30). There were no significant differences between species and sex. Cholelithiasis was predominant (75.0%) in lion tamarins older than 5 years. Septate gallbladder was observed in 86.6% (26/30) of the lion tamarins. Of these, 53.8% (14/26) had gallstones. Biochemical analysis revealed a moderate positive correlation between gamma‐glutamyl transferase and the number of gallstones.ConclusionsAsymptomatic cholelithiasis is frequent in lion tamarins kept under human care. Therefore, systematic monitoring through ultrasound should be part of the preventive care of these animals.

Abstract Objective The aim of this study was to perform gait analysis using a pressure-sensitive walkway in dogs submitted to high (total) or low amputation (partial) of one forelimb or hindlimb. Study Design A total of 39 dogs met the inclusion criteria. The reasons for the amputations were motor vehicle accidents in 38 dogs and possible limb malformation in 1 dog. The amputee dogs were divided into four groups: G1 (n = 10)—high forelimb; G2 (n = 10)—low forelimb; G3 (n = 9)—high hindlimb; and G4 (n = 10)—low hindlimb. For kinetic evaluation, the dogs were walked across a pressure-sensitive walkway. Results In dogs with forelimb amputation, the percentage of body weight (%BW) distribution on the contralateral forelimb was 50.7% in cases of high amputation and 55.5% in cases of low amputation, while the %BW distribution on the hindlimbs, mainly in the ipsilateral hindlimb, was 27.9% in cases of high amputation and 27.1% in cases of low amputation. In cases of high amputation of the hindlimb, the %BW distribution was 71.5% on the forelimbs and 29.7% on the contralateral hindlimb, while in cases of low amputation, the distribution was mainly for the contralateral hindlimb and ipsilateral forelimb. No statistical difference was noted between the amputation levels, except for the contralateral limb in cases of low and high amputation of the hindlimbs concerning the overload percentage and %BW distribution. Conclusion The amputation level of one forelimb did not influence the %BW distribution; however, in the hindlimb, this was higher for the contralateral limb in dogs submitted to high amputation.

This retrospective study aimed to identify the common extra-pelvic injuries at the first admission at the hospital of cats with pelvic fractures. The medical records and radiographs were assessed. Seventy-three cats with pelvic fractures were identified, of which 41 were associated with extra-pelvic injuries. Of the 41 animals with extra-pelvic injuries, 21 were females and 20 were males. Motor vehicle trauma represented 56.09% of the pelvic fracture cause. Injuries to the appendicular skeleton included femur (n=12), tibia (n=1), lateral malleolus (n=1) and olecranon (n=1) fractures, and unilateral hip luxation (n=4). In the axial skeleton, mandibular condyle fracture (n=1), fracture of lumbar vertebrae (n=1), fracture and/or luxation of the coccygeal vertebrae (n=3), and luxation between S3 and the first coccygeal vertebra (n=3) were detected. Sacrum or sacroiliac fractures were detected in six cases. Sacroiliac luxation was verified in 22 cats unilaterally (n=15) and bilaterally (n=7). Respiratory tract lesions were pulmonary contusion (n=2), pneumothorax (n=2), and diaphragmatic hernia (n=1). Lesions of the urinary system organs included bladder rupture (n=3) and bladder entrapment in the hernia (n=1). In the integumentary system, there was one case of cutaneous laceration and one of subcutaneous emphysema. Traumatic hernias of the abdominal wall were found in five cats. Nervous system lesions included traumatic brain injury (n=2) and spinal cord injury (n=1). Two cats presented with constipation. Two animals died, and two were euthanized due to the severity of the injuries. In conclusion, the extra-pelvic injuries at admission were more frequent in the appendicular skeleton, mainly represented by femur fractures. RETROSPEKTIVNA ANALIZA POŠKODB IZVEN MEDENICE, POTRJENIH OB PRVEM SPREJEMU MAČK Z ZLOMOM MEDENICE Izvleček: Namen te retrospektivne študije je bil ugotoviti pogoste zunajmedenične poškodbe ob prvem sprejemu mačk z zlomom medenice v bolnišnico. Pregledali smo medicinsko dokumentacijo in rentgenske slike. Identificirali smo 73 mačk z zlomom medenice, od katerih jih je bilo 41 povezanih z zunajmedeničnimi s poškodbami. Od 41 živali z zunajmedeničnimi poškodbami je bilo 21 samic in 20 samcev. Poškodbe zaradi motornih vozil so predstavljale 56,09 % vzrokov zlomov medenice. Poškodbe privesnega skeleta so vključevale zlom stegnenice (n = 12), golenice (n = 1), lateralnega skočnega sklepa (n = 1) in olekranona (n = 1) ter enostranski izpah kolka (n = 4). V osnem skeletu so bili odkriti zlom čeljustnega kondila (n = 1), zlom ledvenih vretenc (n = 1), zlom in/ali izpah repnih vretenc (n = 3) ter izpah med S3 in prvim repnim vretencem (n = 3). V šestih primerih so bili ugotovljeni zlomi križnice ali križnice in črevnice. Izpah križnično-črevničnega sklepa je bil potrjen pri 22 mačkah, enostransko (n = 15) ali obojestransko (n = 7). Poškodbe dihalnih poti so vključevale kontuzijo pljuč (n = 2), pnevmotoraks (n = 2) in diafragmalno hernijo (n = 1). Poškodbe organov sečil so vključevale rupturo mehurja (n = 3) in ujetje mehurja v hernijo (n = 1). Najden je bil en primer raztrganine kože in en primer podkožnega emfizema. Travmatske hernije trebušne stene so bile ugotovljene pri petih mačkah. Poškodbe živčnega sistema so vključevale travmatsko poškodbo možganov (n = 2) in poškodbo hrbtenjače (n = 1). Dve mački sta imeli zaprtje. Dve živali sta poginili, dve sta bili zaradi resnosti poškodb evtanazirani. Zaključimo lahko, da so bile zunajmedenične poškodbe ob sprejemu pogostejše na privesnem skeletu, ki so jih predstavljali predvsem zlomi stegnenice.

Objectives This study aimed to evaluate renal measurements by B-mode ultrasound in kittens during their first 3 months and compare them with those of young adult cats. Methods Forty-eight healthy mixed-breed cats (24 males and 24 females) were enrolled in this study. The cats were divided into six age groups: groups 1–5 (kittens) and group 6 (young adult cats). Each kidney was examined using B-mode imaging and the following measurements taken: renal length (RL), renal height (RH), renal width (RW), cortical thickness (CoT), medullary thickness (MdT) and corticomedullary ratio (CMr). The ratio and correlation of RL to aortic diameter (AoD) and the length of the fifth/sixth lumbar vertebrae (LLV) were also determined. Results Among groups, there was a statistically significant difference between RW, renal volume (RV), CoT, MdT and CMr. The smallest renal dimensions were obtained in the youngest kittens (up to 10 days of age), including RL (1.84 ± 0.40 cm), RH (1.14 ± 0.17 cm), RW (1.25 ± 0.20 cm) and RV (1.47 ± 0.68 ml). A strong correlation was observed between RL:AoD and RL:LLV, allowing for linear regression equations and reference intervals for RL:AoD and RL:LLV to be created for each age group. Conclusions and relevance B-mode ultrasound showed that renal measurements in kittens differed from those in young adult cats, and that the renal dimensions, renal CoT and CMr increased with the growth of the cat. The RL-LLV ratio is a reliable method for measuring RL according to age group.

This study aimed to compare renal function between obese and normal‑weight healthy cats, using intrarenal resistive index (RI), serum symmetric dimethylarginine (SDMA), and serum creatinine, and to identify the variables that might influence intrarenal RI. Thirty crossbred client‑owned cats met the inclusion criteria and were allocated into two groups: Control and Obese. Body weight, body mass index (BMI), body condition score (BCS), SAP, serum SDMA, urea, and creatinine were evaluated. B‑mode and Doppler ultrasound of the kidneys were done. RI evaluation was in the interlobar artery. SDMA and intrarenal RI were compared between groups, also considering the gender of the cats. A correlation analysis between intrarenal RI with the other parameters was performed. SDMA was higher in the Obese group. Intrarenal RI was higher in females than males in the Obese group. Obese females presented higher RI and SDMA than Control females. A positive correlation was observed between RI, age, body weight, and BMI. Six obese cats (40%) showed increased RI. The increase in body weight, BCS, and BMI resulted in a simultaneous increase in RI and SDMA. The RI may assist in monitoring renal function, and may be associated with preclinical kidney changes in obese cats.

ABSTRACT Purpose: To evaluate in-vivo degradation of two bioabsorbable interference screws. Methods: Twenty-two crossbred Santa Inês ewes were used. A poly-DL-lactide (PDLLA) screw (70%/30%) was inserted in the right pelvic limb, and a PDLLA screw (70%) + β-tri-calcium phosphate (β-TCP) (30%) in the left pelvic limb. Animals were euthanized at one, four, seven and a half and 18 months after surgery. Plain radiography, computed tomography (CT), microCT, and histological analysis were accomplished. Results: PDLLA screw was hypodense at all evaluation moments, but with progressive density increase along the central axis, whereas PDLLA/β-TCP was initially hyperdense and progressively lost this characteristic. No adverse reactions were observed on histological evaluation. Conclusions: The inclusion of β-TCP favors screw degradation since the PDLLA/β-TCP screws evidenced a more intense degradation process than the PDLLA screws at the last evaluation. PDLLA screws showed higher bone production, evident around the screw thread, inside the lateral perforations, and in the central canal, whereas the PDLLA/β-TCP screws presented less bone tissue at the implantation site.

AbstractThis study aimed to perform quantitative and qualitative evaluations of the lateral and third ventricles, and brain parenchyma, in healthy dogs of different skull conformations on CT scans. Forty‐five adult client‐owned dogs were divided into three groups according to skull conformation: G1 (dolichocephalic)—15 German Shepherds; G2 (mesaticephalic)—15 Rottweilers; G3 (brachycephalic)—15 Boxers. Transverse plane images were used for quantitative and qualitative evaluations of the lateral ventricles and third ventricle, and pre‐ and post‐contrast brain parenchyma. The height of both ventricles and brain was measured at the level of the interthalamic adhesion. Ventricle height, brain height, and ventricle/brain height ratio were statistically higher in G3 compared with G1 and G2 that were similar. The third ventricle was visible but unmeasurable in five dogs from G1 and three from G2. In G3, all dogs had third ventricle visible and measurable in all images. Asymmetric ventricles were seen in five dogs in Group 1 and Group 2, and seven in Group 3. Brain parenchyma had homogenous density in 80% of the dogs in all groups. Contrast enhancement of the rostral midline was visualized in all dogs. In conclusion, brain CT scans of healthy dogs showed that the qualitative data were similar among groups, but lateral ventricle and brain measurements in brachycephalic dogs differed from the dolichocephalic and mesaticephalic dogs.

AbstractBaseline data for wall thickness in healthy toucans can be used to diagnose disease in sick individuals. This study aimed to evaluate the use of ultrasonography for the examination of the gastrointestinal tract of healthy toco toucans (Ramphastos toco). Ten non‐anaesthetized healthy adult toco toucans were evaluated. Food was withheld for 3 h prior to the ultrasound examination. Longitudinal and transverse images of the gastrointestinal tract were obtained using ventromedian cranial and ventromedian caudal approaches to evaluate the morphology and stratification. The wall thickness of the sections was measured: proventriculus and ventriculus, duodenum, jejunum/ileum, and cloaca. Additionally, the thickness of the mucosal layer of the duodenum and jejunum/ileum was also measured. Subsequently, the ratios of the duodenal wall thickness to the duodenal mucosa layer and the total wall thickness of the jejunum/ileum to the jejunum/ileum layer mucosa were stablished. The wall thickness of the proventriculus was significantly higher than the wall thickness of ventriculus. The wall thickness of the duodenum was significantly higher than the wall thickness of jejunum/ileum. The mean ratios of the duodenal wall thickness to the duodenal mucosa layer and the wall thickness of the jejunum/ileum to the jejunum/ileum layer were 83.15% and 80.07%, respectively. In conclusion, it was possible to assess the stomach and intestines using ultrasound examination in healthy toco toucans, due to their medium body size and no interference by surrounding air sacs.
