title: Equine ocular hemangiosarcoma: case report

description: Equine ocular hemangiosarcoma is a rare and aggressive malignant tumor of vascular endothelial origin. We describe a case of ocular hemangiosarcoma in a 10-year-old mare with serosanguineous secretion arising from a mass involving the bulbar conjunctiva and third eyelid of the right eye. The diagnosis was based on histopathological evaluation and immunohistochemistry. Enucleation was performed as complete surgical excision of the affected tissue, with no recurrence or metastasis of the lesion being observed after six months of.

title: Morphology and vascularization of the corpus luteum of peccaries (Pecari tajacu, Linnaeus, 1758) throughout the estrous cycle

description: The current paper characterizes the changes in morphology and vascularization of the corpus luteum of collared peccaries during the estrous cycle and correlates progesterone synthesis (P4). Twenty females were subjected to a treatment for estrus synchronization; an ear implant containing 1.5 mg of norgestomet was implanted on D0, whereas on D9 the peccaries received an IM injection of eCG 200UI and 50g of PGF2a. The animals were divided into four groups (G1, G2, G3 and G4) and euthanized on post-ovulation days 3, 12, 18 and 22. The ovaries were collected and the corpora lutea were measured and processed for histological and vascular density (Dv). Blood was collected for dosage of P4 serum. The morphology of the ovaries, the corpora lutea and P4 varied significantly during the estrous cycle (P&lt;0.001). There was a significant co-relationship between weight and length of the ovaries and CL (r = 0.66, r = 0.52, P&lt;0.05, respectively) and between weight, length and width of the CL and P4 (r = 0.51, r = 0.54 and r = 0.68, P&lt;0.05, respectively). The luteal Dv was highly influenced by the estrous cycle phase (P&lt;0.0001). The P4 and luteal Dv concentrations were higher in G2 and evidenced maximum secretory activity, with a highly significant correlation (P&lt;0.0001). Assessed lutein parameters may estimate the phase of the estrous cycle in peccaries and the functional activity of the corpus luteum.

title: Morphometric characterization of Campolina mares, stallions and gelded horses using indexes

description: The present study aimed to evaluate the morphometric indexes for Campolina stallions, gelded and mare horses, as well as morphologically characterizing them. For this purpose linear measurements from 4.840 stallions, 19.037 mares and 1371 gelded horses were used, obtained from ABCCCampolina's stud book database, from which nine morphometric indexes were calculated from six linear measurements. Analysis of variance was carried out to evaluate the effect of sex and age on the indexes obtained. We found that both factors influenced the morphometric index. Stallions have presented higher estimate body weight values than mares and gelded horses. According to the pectoral index values all categories were classified as far from the ground. According to body index and dactyl thoracic index average values, stallions and gelded horses were classified as medium lined and middleweight, respectively, once the mares were classified as more compact and overweight. It is concluded that Campolina stallions and gelded horses fall within the breed standard for saddle animals, but mares don't. However, the compact indexes 1 and 2 showed contradictory results and need to be better evaluated for its intended use in classifications. For most indexes gelded animals showed better proportion than the other categories.

title: Serum biochemical profile from clinically healthy Campeiro horses

description: ABSTRACT Blood samples were obtained from 138 equines of the Campeiro breed with mean ages of 9.7±5.4 years, including 14 males (10.15%) and 124 mares (89.85%). Mean values of serum of GGT: 13.73 ± 4.08U/L; AST: 246.34±72.87U/L; ALT 5.13±1.18U/L; FA: 284.32±53.33IU/L; CK: 132.54±72.25U/L; LDH: 511.38±143.65U/L; and serum urea: 38.65±12.62mg/dL and creatinine: 1.24±0.24mg/dL were observed. The mean values of AST, FA, ALT, urea and creatinine were similar to those proposed in the literature for other breeds. The CK values, GGT, and LDH were higher than those commonly used as references. There was no difference in the concentrations of any of the serum components evaluated at different ages analyzed. Further average values in the lower urea concentrations and creatinine were observed in females compared to males, as well as the higher serum activity of FA in pregnant mares in relation to non-pregnant. Serum biochemical profile of healthy horses of the Campeiro breed presents peculiar variations that must be taken into consideration in the interpretation of laboratory tests.

title: B-mode and Doppler ultrasonography of adrenal glands of healthy dogs

description: ABSTRACT The aim of this study was to determine the vascular indices of adrenal blood flow in healthy dogs (systolic velocity - SV; diastolic velocity - DV; resistance index - RI). Eighteen dogs (thirty six adrenal) were studied. Physical examination, biochemical profile and dexamethasone suppression test were performed to determine general health status. Echotexture, size, contours and margins, and overall shape of the adrenal gland (right and left) were assessed via ultrasound. By spectral Doppler of the phrenic-abdominal artery, the SV, DV, and RI were acquired. Animals did not show alterations in clinical and laboratory examination and suppression of cortisol. Normal homogeneous and echotexture, regular contours and margins and normal shape and size were verified via B mode. Spectral Doppler of the phrenic-abdominal artery showed monophasic-patterned waves and low vascular resistance and systolic peak evident with means values: left adrenal - SV = 31.34cm/s, DV = 9.54cm/s and RI = 0.69; and right adrenal - SV = 27.83cm/s, DV = 7.71cm/s and RI = 0.68. Doppler evaluation of adrenal was easily implemented and may provide base line data in the study, allowing for the use of this technique as a diagnostic tool for diseases of the dog's adrenal.

title: Electromyographic analysis of the gait cycle phases of boxer dogs

description: ABSTRACT Systematic studies involving technologies such as surface electromyography (sEMG) may provide important data that enable veterinarians to recognize musculoskeletal, ligamentous, and neurological alterations. The aim of this study was to describe the gait cycle phases and the timing of muscle activation in healthy Boxer dogs during gait by means of sEMG. The gait cycle of seven Boxer dogs was evaluated and sEMG was recorded from the biceps brachii, triceps brachii, brachiocephalic, rectus femoris, semitendinosus, semimembranosus, and superficial gluteal muscles of the right hemibody. Circular monopolar Ag/AgCl electrodes were attached to the mean point between the motor point and the muscle insertion. The electromyographic signals were collected by an active interface with 20-fold gain in a bipolar differential configuration using a 16-channel signal conditioner (EMG Systems Brasil), while the dogs walked on a treadmill at a speed of 2m/s. Pearson's correlation was used for the statistical analysis. A positive correlation was found between the rectus femoris and biceps brachii (r= 0.81); superficial gluteal and triceps brachii (r= 0.69); semitendinosus-semimembranosus and biceps brachii (r= 0.76); and rectus femoris and semitendinosus and semimembranosus muscle groups (r=0.99). The biceps brachii and brachiocephalic muscles work in tandem to position the thoracic limb during the gait cycle, while the semitendinosus-semimembranosus group flexes the knee and, simultaneously with the quadriceps that flexes the hip, prevents the contact of the pelvic limb with the ground during the swing phase. The body is propelled forward by the triceps brachii muscle, which extends the elbow and flexes the shoulder at the final contact, while the superficial gluteal muscle extends the hip.

title: Gastrointestinal stromal tumors in dogs: a clinicopathologic study

description: ABSTRACT Gastrointestinal stromal tumors (GIST) are uncommon and show high histological similarity with smooth muscle and peripheral neuron tumors. This paper reported three cases of gastrointestinal stromal tumor (GIST) showing its clinical and laboratorial presentation, and gross, microscopical and immunohistochemical features. Clinical signs and symptoms of the animals studied were progressive and characterized by nonspecific chronic gastrointestinal disorders such as depression, anorexia, weight loss and melena. Non regenerative anemia and leukocytosis were the main laboratory findings. Grossly, tumors were 19cm big, ulcerated and with necrotic areas. Microscopically, the tumors were malignant spindle cell proliferation with positivity to vimentine and CD117, with neural (S100+), myogenic (desmine + and smooth muscle actine+) and anaplasic differentiation. GIST should be one of the differential diagnoses to be considered among the mesenchymal neoplasms of the gastrointestinal tract of dogs.

title: Synthetic pigments for Japanese quail fed diets with sorghum

description: ABSTRACT Corn is the major energy ingredient in diets, and many ingredients have been tested aiming to replace it. In this regard, sorghum stands out for its chemical profile similar to that of corn. However, because it is low in carotenoids, its inclusion in diets reduces the egg yolk color pigmentation, which can be corrected by the addition of synthetic pigments. This study aimed to evaluate the performance and egg quality of Japanese quail (Coturnix japonica) supplemented with red (canthaxanthin) and yellow (apo-ester 10%) synthetic pigments. A total of 150 quail at 70 days of age were distributed according to the experimental diet [R1: corn-based control diet (DC); R2: sorghum-based diet (DS); R3: DS + yellow; R4: DS + yellow + red; and R5: DS + red] with six replications and five birds per experimental unit, for 28 days. Performance, egg quality, yolk color, and feed cost characteristics were evaluated. Regression equations were estimated for the effects of color as a function of periods, and treatment means were compared by Tukey's test at 0.05 probability. There was no significant effect (P&gt;0.05) of additives on the quail productive traits. However, addition of synthetic pigments significantly improved the chromatic profile of the yolks (P&lt;0.05). Inclusion of synthetic pigments improves yolk color, but should be evaluated according to market demands.

title: Influence of gender on carcass yield of twin lambs Blackbelly x Pelibuey at 56 days of age

description: ABSTRACT The aim of this study was to determine the influence of gender on pre-weaning growth, yield and weight of primal cuts of the carcass of Blackbelly x Pelibuey lambs. 16 twin lambs were used. The lamb gender was the fixed factor. The variables evaluated were: body weight at birth and at weaning, average daily weight gain, weight and yield of carcass and primal cuts: neck, arm, thorax, abdomen and leg. Gender did not affect (P&gt;0.05) body weight at birth. However, the pre-weaning average daily weight gain and body weight at weaning were affected (P&lt;0.05) by the gender. Hot carcass yield and weight and primal cuts were not affected (P&gt;0.05) by the gender of the lamb. Nevertheless, the area of the Longissimus dorsi muscle and cavity fat were different between males and females (P&lt;0.05) 11.5±0.73cm2 and 198±0.05 g vs 9.3±0.73cm2 and 282±0.05g, respectively. In conclusion, in twin lambs Blackbelly x Pelibuey males had greater average daily weight gain and body weight at weaning than females. Carcass yield and weight and primal cuts were not affected by the gender of the lamb. However, males had greater area of the L. dorsi muscle than females and these in turn had a greater amount of cavity fat than males.

title: Evaluation of different fixatives for histological studies in canine ear skin

description: ABSTRACT The biological fixatives have an important role in the final histology quality. In veterinary, routine skin biopsy is a common procedure and the choice of fixative is essential for the final result. The most common fixative is Formalin, even though it is toxic, carcinogenic, and has low and slow penetration. Still, there isn't a fixer which can replace the qualities of formalin. The aim of this study was to evaluate qualitatively the preservation of the histological features of dog skin using different tissue fixative embedded in paraffin, sectioned and stained with hematoxylin - eosin. We used a 4 mm punch pen to collect ear skin samples in six dog cadavers. After collection, the tissues were fixed in: (1) Bouin for 6 hours; (2) Carnoy for 4 hours; (3) 10% buffered formaldehyde for 24 hours, all under refrigeration (4 ° C). The tissues were then processed, sectioned and stained with hematoxylin and eosin. The slides were evaluated blindly by four different pathologists who considered the qualitative aspects below: (1) quality of coloring; (2) preservation of the histological characteristics; (3) preservation of cytoplasmic boundaries using a Likert scale score for each blade. The fixative with the highest mean score on all items was buffered formalin with 3.76 points followed by Bouin (3.39) and Carnoy (2.52). Formaldehyde can bring health a risk of professional routine handling, so it is necessary to search for a biological fixative with the same qualities being less harmful to health.
