The present study aimed to describe the disposition and amount of circumvallate lingual papillae in Saanen goats using 26 goat tongues from the Laboratory of Animal Anatomy and Morphology of the Federal Rural University of Rio de Janeiro, which were previously fixed in 10% formaldehyde solution for later dissection of tongues that were removed from the oral cavity for the necessary studies. After identification, morphometric data were tabulated and submitted to statistical analysis for further description. In descriptive statistics, the mean of 17.85 was close to the median of 17.5 and the overall dispersion (standard deviation) was relatively low (2.24), which represents a coefficient of variation (CV) of 12.8 %. Confidence interval for mean with 95 % with 99 % confidence was also performed. Regarding the distribution of papillae, 21 tongues (80.7 %) of the total samples were located on the side of the tongue root, 3 tongues (11.5%) were distributed on the side of the tongue root, migrating toward the tongue median sagittal plane, 1 tongue (3.8 %) was located in the concave position on the side of the tongue root and 1 tongue (3.8 %) was disposed on the sides of the tongue, with some papillae arranged close to the region of the tongue median sagittal plane. © 2017, Universidade Federal de Uberlandia.

Random regression models are currently used in genetic evaluation of beef cattle, because they allow changes in the mean and variance of the trait over time as well as estimation of (co) variances between any points along the growth curve. This study aimed to estimate (co)variances and genetic parameters for growth traits of Nelore cattle by random regression using models with heterogeneous and homogeneous residual variance. We utilized 23,278 weight records from birth to 550 days of age, from animals born between 1993 and 2010. The best-ftting model considered direct genetic, maternal genetic, permanent environmental animal and maternal permanent environmental effects, adjusted by fourth, third, sixth and fourth order polynomials, respectively. Heritability estimates for direct genetic effect increased from 120 to 450 days of age and then decreased at 550 days of age. Values at 120, 210, 365, 450 and 550 were 0.23, 0.23, 0.38, 0.52 and 0.43, respectively. Estimates of maternal heritability were low for all ages analyzed, ranging from 0.01 to 0.08. The genetic correlations were moderate to high, even at age extremes.

The nefrotoxicity of prednisone in cats was evaluated, using an immunesupressor dose (5 mg/kg/day), by establishing blood count, serum biochemistry (urea and creatinine) and urinary (GGT, protein and creatinine) parameters and urinalysis. Eight cats were used. The animals were of undefinied breed, adults and with average weight of 3 kg. They were housed in four cubicles and fed with two measures of commercial ration per day and water ad libitum during an adaptation period of seven days. The trial design was entirely random, being rejected any specific criterion of inclusion in this study besides the absence of any previous kidney damage. Animals received 5 mg/kg prednisone, orally, every 24 hours for a period of 14 days. The samples were collected in two different times, with the animals resting before prednisone administration (M1), and 14 days after the administration (M2). Significant differences were found in some hematological and biochemical parameters as well as in urinalysis. It was concluded that the prednisone (5 mg/kg/day), during a period of 14 days, is potentially nephrotoxic and the determination of the urinary GGT activity was proven to be precisely sensitive to early proximal tubular injury.

The serum biochemical values allow to establish reference used in metabolic and clinical evaluations of calves, reducing losses in cattle breeding. The aim of this study was to evaluate the influence of age on serum biochemical profile in Senepol calves, at the first 120 days of age. The experiment was conducted in the city of Uberlândia, Minas Gerais, Brazil, in four periods after birth (0-15, 30, 60 and 120 days of age). Blood samples were obtained by jugular venipuncture for determination of serum total protein, albumin, globulin, triglycerides, cholesterol, AST, GGT, FA, calcium, phosphorus, magnesium, creatinine and urea. Cholesterol remained at minimum reference values or below throughout the experiment. Animals at 30 days showed the lowest values of protein concentrations, minerals and triglycerides that normalized up to 60 days of life, except to albumin that slower recovery was showed. Our data showed that the serum biochemical profile in Senepol is influenced by age up to 120 days of age; moreover there are differences with other breeds.

The canine monocytic ehrlichiosis is a cosmopolitan disease, caused by Ehrlichia canis, transmitted by ticks Rhipicephalus sanguineus that has been frequently diagnosed in dogs throughout the country. This study aimed to investigate the cytological and molecular Ehrlichia infection in 195 dogs examined at the University Veterinary Hospital of Mato Grosso, by analyzing the clinical and laboratory findings. In 48 dogs with positive cytology for Ehrlichia sp it was possible to detect the diversity of signs, with predominance statistically significant of pallor of mucous membranes (P≤0.05) as well as several hematological findings, occurring anemia, leucopenia and thrombocytopenia, or increased as normal cells. There was increased of plasma proteins, with hyperglobulinemia, however without any significant difference (P≥0.05), although this finding is common in that infection. Through the nested PCR technique it was possible to confirm the infection by E. canis in the city of Cuiaba.

The shunt portosystemic or portosystemic deviation (PSD) are unique or multiples vascular communications between the systemic circulaton and the portal circulation, that permit blood flow reaches the circulatory system without first passing trhought the hepatic metabolization. May be acquired or congenital and can also be classified as intrahepatic located within the liver or extrahepatic located outside the liver parenquima. The acquired form is usually associated with intra-hepatic disorders. They usually suggest tortuous vessels that communicate with the caudal vena cava in the region of the left kidney. The congenital form is associated with genetic lineage and one of the most affected is Maltese breed. This case report describes the diagnostis and treatment of a eight year-old female Maltese dog presenting extrahepatic Portosystemic Shunt. The patient showed signs of hepatic encephalopathy, such as restlessnees, weakness, deambulation, head tremor and impaired visual. Complementary exam demonstrated: postprandial glicemia near the lower limit of reference, alkaline phosphatase (ALP) and alanine aminotransferase (ALT) increased and hipoalbuminemia. Ultrasonography revealed the presence of vesical calculus and bilateral kidney, liver decreases and increased echogenicity, gallbladder with anechoic content and high cellularity may suggest liver/colangiohepatopatia and extrahepatic DPS was detected. The use of Doppler assisted in identifying the location of the bypass communication and the turbulence detecting the extrahepatic DPS. Protein-restricted diet and antibiotic therapy with amoxicillin achieved good results. The clinical treatment was decided make only the clinical and maintain the quality of life of the patient. © Pleiades Publishing, Ltd., 2011.

The objective of this study was to determine the frequency of animals that tested positive for brucellosis and leptospirosis and the risk factors for these diseases in the State of Paraíba. A total of 136 buffaloes from 14 herds were examined. For brucellosis, we used the buffered acidified plate antigen (BAPA) test as screening method and 2-mercaptoethanol as confirmatory test. For leptospirosis, we conducted a microscopic agglutination test (MAT), with a cut-off point of 1:100. Of the animals examined, two [1.5%; 95% CI = 0.4%-5.2%] were positive for brucellosis, and 38 (27.9%; 95% CI = 21.1%-36.0%) were positive for leptospirosis. The brucellosis-positive animals were from two (14.3%) herds, while nine (64.3%) herds had leptospirosis-seropositive animals. The more frequent Leptospira spp. serotypes were Bratislava, Pomona, and Canicola. We concluded that leptospirosis was widespread in buffaloes in the state of Paraíba and suggested that breeding alongside horses and pigs might be an important factor in the spread of leptospirosis-positive animals. The presence of brucellosispositive animals indicated the possibility of negative-impacting measures on disease control in bovines, and it is therefore recommended that greater attention be given to these animals for brucellosis control.

The objective of this study was to evaluate the gynecological examination and endometrial cytology in Holstein cows with more than three repetitions of estrus. The experiment was conducted in six commercial dairy herds both with similar reproductive and sanitary managements and assisted by veterinarians. It was included only Holstein cows up to five calving and more than three consecutive repetitions of estrus. Seventy-seven cows were identified and carried gynecological examination and endometrial cytology. The reproductive causes found in this study, subject to involuntary culling, were: clinical endometritis.with purulent vaginal discharge and more than 3% neutrophils (7.79%), clinical endometritis with purulent vaginal discharge and less than 3% neutrophils (2.6%), subclinical endometritis (10.4%), urovagina (1.3%) and 77.9% cows with unknown causes and they were not associated with reproductive disorders evaluated. It was concluded: A) the rate of cows without diagnosis is very high and it interferes directly to the reproductive performance; b) the proposed examination diagnosed 22.1% of clinical disorders that might be prevented or treated and thus decreasing the involuntary culling.
