RESUMO
The present study evaluated the use of haptoglobin (Hp) as an indicator of health and performance in 166 Holstein heifer calves reared in an intensive production system. Calves were evaluated at D6-9; D10-13; D20-23; D35-38 and D65-68, corresponding to the days of life. The absence or presence of diseases was evaluated by physical examination and classification of scores. The performance parameters evaluated were body weight, height at withers and hind width. Hp was measured by spectrophotometric technique. The highest prevalence of diarrhea (59.4%; 98/165) was observed in D10-13, bovine respiratory disease (BRD) was on D35-38 (25.8%; 42/163), and umbilical inflammations in D6-D9 (7.8%; 13/166). Highest values of Hp were observed in animals with diarrhea (P=0.02), and umbilical inflammation (P=0.057), in comparison with the group of healthy calves. A significant negative correlation was observed between Hp and performance index. This protein presented an important relation with diarrhea and performance of the calves, opening perspectives on its utilization as a biomarker of diseases.(AU)
O presente estudo avaliou o uso da haptoglobina (Hp) como indicadora de sanidade e desempenho em 166 bezerras Holandesas criadas em um sistema de produção intensivo. As bezerras foram avaliadas nos momentos D6-9; D10-13; D20-23; D35-38 e D65-68, sendo estes correspondentes aos dias de vida. A ausência ou a presença de doenças foi avaliada por meio do exame físico e da classificação por escores. Os parâmetros de desempenho avaliados foram peso corporal, altura de cernelha e largura de garupa. A Hp foi mensurada por técnica espectrofotométrica. A maior prevalência de diarreia (59,4%; 98/165) foi observada em D10-13, doença respiratória bovina (DRB) ocorreu em D35-38 (25,8%; 42/163) e inflamações umbilicais em D6-D9 (7,8%; 13/166). O valor de Hp foi maior nos animais que apresentaram diarreia (P=0,02) e inflamações umbilicais (P=0,057), em comparação ao grupo de bezerras saudáveis. Houve correlação negativa significativa entre a Hp e os índices de desempenho. Essa proteína apresentou uma importante relação com a diarreia e com o desempenho das bezerras, abrindo perspectivas sobre a sua utilização como biomarcadora de doenças.(AU)

A fim de comparar as abordagens abdominais, pela linha mediana ventral e lateral direita em cadelas pré-púberes e adultas submetidas a ovariossalpingo-histerectomia, utilizaram-se 28 cadelas hígidas, distribuídas em dois grupos experimentais de igual número: grupo abordagem mediana ventral (AMV) e grupo abordagem lateral direita (ALD), com sete animais adultos e sete animais pré-púberes em cada grupo. O procedimento cirúrgico foi dividido em nove manobras cirúrgicas distintas, e o tempo para conclusão de cada uma delas, suas facilidades e dificuldades, assim como o tempo cirúrgico total, foram determinados. O tempo médio desde o início da incisão da pele até a entrada na cavidade peritoneal foi menor nas cadelas adultas (P≤0,001) e pré-púberes (P≤0,001) do grupo AMV, mas o tempo médio para identificação uterina foi menor nas cadelas pré-púberes (P≤0,001) do grupo ALD. O tempo cirúrgico total foi menor utilizando-se a abordagem lateral direita (grupo ALD) nas cadelas adultas (P≤0,001) e pré-púberes (P≤0,001). Seu uso não se relacionou com complicações cirúrgicas e facilitou a identificação uterina, possibilitando redução no tempo cirúrgico total. Assim, a abordagem lateral direita demonstrou ser uma alternativa segura em cadelas adultas e pré-púberes submetidas à OSH eletiva.
In order to compare the abdominal approaches, through the ventral midline and right lateral in pre-pubertal adult female dogs undergoing ovariohysterectory we used 28 otherwise healthy dogs, divided into two experimental groups of equal number: Ventral Median Approach Group (VMA) and Right Side Approach Group (RSA), with seven adult animals and seven pre-pubertal animals in each group. The surgical procedure was divided into nine different surgical maneuvers, and the time required for completion of each of them, their strengths and difficulties, as well as the total surgical time were determined. The time from the start of the skin incision to the entrance into the peritoneal cavity was lower in adult female dogs (P≤0.001) and pre-pubertal (P≤0.001) in the VAM group, but the time for uterine identification was lower in pre-pubertal female dogs (P≤ 0.001) in the RSA group. The total surgical time was shorter using the right lateral approach (RSA group) in adult (P≤ 0.001) and pre-pubertal (P≤0.001) female dogs. Thus, the right-side approach has proved to be a safe alternative in adult and pre-pubertal dogs undergoing elective OSH. Its use was not associated with surgical complications, and facilitated uterine identification, allowing a reduction in the total surgical time.

BACKGROUND: Presence of tumor markers in serum might be connected to the number of secreting cells and with the stage of the neoplasm. However, there are few studies regarding these markers in veterinary clinical oncology. OBJECTIVES: To determine the serum concentrations of cancer antigen 15.3 (CA 15.3), carcinoembryonic antigen (CEA), and lactate dehydrogenase (LDH) in female dogs with different stages of mammary cancer. ANIMALS: Ninety female dogs, including 30 that were healthy, 40 that had nonmetastatic cancer, 12 with regional metastasis, and 8 with distant lymph node metastasis. METHODS: Prospective case-controlled observational study. Serum samples were collected to measure CA15.3, CEA, and LDH from 60 female dogs with mammary cancer during mastectomy and 30 healthy female dogs during routine check-up. CA15.3 and CEA were determined by chemiluminescent immunoassay and LDH by ultraviolet kinetic method. Western blotting analysis was performed to confirm the specificity and possible cross-reactivity of human CA15.3 and CEA antibodies with canine serum. Group data were compared by ANOVA followed by Student-Newman-Keuls and Tukey's tests. Correlations were investigated by Pearson and Spearman tests. RESULTS: CEA, CA15.3, and LDH were measurable in all groups. Higher serum concentration of CA15.3 and LDH was associated with regional and distant metastases. There was a significantly higher serum CA15.3 concentration in animals with lymph node metastasis when compared with animals without metastasis. There were no significant differences in CEA among groups. Expression of CA15.3 and CEA in canine serum was confirmed by Western blotting. CONCLUSIONS AND CLINICAL IMPORTANCE: Serum CA15.3 can be used to distinguish nonmetastatic from metastatic carcinomas.

This study evaluated the effects of homeopathic treatment on control of Haemonchus contortus infection in sheep. Twenty lambs were randomized to three treatments: treated with the homeopathic medicines, Ferrum phosphoricum, Arsenicum album and Calcarea carbonica; treated with a conventional antihelminthic, doramectin, and an untreated control group. Fecal and blood samples were taken from each animal on days 18, 38 and 68 after start of treatment. A significant reduction in number of H. contortus larvae (p<0.01) was observed for animals in the homeopathic treatment group compared to the control group. Fecal egg counts showed negative correlation between haematocrit and haemoglobin concentrations in the homeopathic treatment group (p<0.01); however, the biochemical and immunological parameters showed better correlation, indicating that the homeopathic medicine improved vital functions. Daily weight gain in the homeopathic treatment group was superior to the control and to the antihelminthic groups, 31 and 6.5%, respectively. The cost benefit analysis confirmed that homeopathy group increases economic trend when compared with the other groups.

The proteinogram of six 12 month-old Alpine goats, intensively raised and naturally infected by gastrointestinal parasites, was evaluated. Blood and feces samples of each animal were monthly collected. Total serum protein and their fractions were determined by agarose gel eletrophoresis, using Tris buffer, pH 9.2. The identified protein fractions were albumin, alfa-globulin, beta1-globulin, beta2-globulin and gama-globulin, whose average and standard deviation (g/dl) were, respectively: 2.35±0.39, 0.69±0.36, 0.70±0.08, 0.48±0.08 and 1.52±0.41. It was not observed significative correlation (P>0.05), according to the Spearman non-parametric test, either between the Strongyloides eggs count per gram of feces or the Haemonchus spp. larval count per gram of feces and the fraction electrophorectly variable.(AU)

The molluscicide activity of hexanic extract from Anacardium occidentale L. (cashew) nut shell, of copper (II) complex, of lead (II) complex and anacardic acid has been compared in the laboratory in an attempt to obtain better stability than anacardic acid. This was obtained from the hexanic extract of the cashew nut shell by precipitation with lead (II) hydroxide or cupric sulfate plus sodium hydroxide or (II) cupric hydroxide followed by treatment of lead (II) complex with a diluted solution of sulfuric acid. Ten products of the mixture obtained were tested on adults snails of Biomphalaria glabrata at 1 to 10 ppm. The most active products were copper (II) complex, obtained by cupric sulfate plus sodium hydroxide, and anacardic acid (sodium hydroxide) which presented activity at 4 ppm. The anacardic acid's lead content was above the limits accepted by the United States standards.
