Resumo: O objetivo deste trabalho foi correlacionar o volume globular com a coloração da mucosa ocular verificada pelo método Famacha de controle da verminose em caprinos pertencentes ao quarto lote de animais com diferentes graus de resistência na região semi-árida do Nordeste brasileiro. Baseados na contagem de ovos por grama de fezes (OPG), caprinos jovens F2 (½ sangue Anglo-nubiana x ½ sangue Saanen) foram classificados em resistentes (n=12) e susceptíveis (n=12) a Haemonchus contortus. Semanalmente observou-se a coloração da mucosa ocular e foi realizada a coleta de sangue para a determinação do volume globular. Para as análises de correlação entre VG e Famacha, foram considerados os valores de VG≤19%, VG≤22% e VG≤27% e dos graus Famacha 3, 4 e 5 como ponto de corte. O ponto de corte de VG19 não foi adequado para avaliar a correlação entre a coloração da mucosa ocular e o Famacha, sendo que o valor de VG22 apresentou maior sensibilidade, portanto mais adequado para esta espécie. Correlation between packed cell volume and Famacha in goats belonging to fourth batch from resistant and susceptible animals to Haemonchus contortus Abstract: The aim of this study was to correlate the packed cell volume with Famacha method to endoparasites control in goats with different degrees of resistance in semi-arid region of the Northeast of Brazil. Based on EPG (eggs per gram) counts, young goats F2 (½ blood Anglo-Nubian x Saanen ½ blood) were classified as resistant (n=12) and susceptible (n=12) to Haemonchus contortus infections. Weekly, the color of ocular mucosal was observed according to Famacha method and blood was was collected to determine the packed cell volume. For correlation analysis between packed cell volume and Famacha were considered values of VG?19%, VG?22% and VG?27% and The VG19 it was not an ideal parameter to evaluated the correlation between the color of ocular mucosa and Famacha, whereas the VG22 was the most sensible, being the best value to be used as cutoff in goats F2.

Old vineyards may present high copper (Cu) content in the soil due to the frequent application of Bordeaux fungicide to control leaf fungal diseases. Thus, many wine makers replace copper fungicides by those made of zinc (Zn) and it leads to the accumulation of these two elements in vineyard soils, fact that may potentiate the occurrence of physiological disorders and morphological changes in the plant root system. The aim of the current study was to assess the effects of high Cu and Zn contents in a sandy acid soil on the physiological state and development of the root system in young grapevines. The soil was taken from a vineyard from Southern Brazil, and then it was sieved and had its acidity and P and K contents corrected. Next, the soil was subjected to the application of 0 and 120 mg Cu kg?1 ; each one of these doses was added with 0, 120 and 240 mg Zn kg?1 , thus totaling six treatments. After the treatments were added to the soil samples, 2.4 kg of soil was stored in rizoboxtype containers. One young grapevine plant was transplanted to each box. The transplanted plants were cultivated for 60 days in greenhouse. The accumulation of root and shoot dry matter was set after the experimental period, as well as the Cu and Zn contents in the roots and shoot, the root system morphology, the chlorophyll a fluorescence, the photosynthetic pigments, the gas exchanges and the superoxide dismutase enzyme activity (SOD). Young grapevines presented mechanisms to tolerate high Cu and Zn concentrations in the soil, mainly through the retention of such metals in their roots to diminish translocation to the shoot. However, the highest Cu and Zn doses led to grapevine plant growth decrease, to gas exchange alterations and to photochemical efficiency reduction associated with photosynthetic pigment decrease and to non-photochemical energy dissipation increase. Moreover, the SOD activity was greater in intermediate Zn doses, thus indicating antioxidant system activation. Thus, the combination between high Cu and Zn concentrations in vineyard soils will enable minimizing the toxic effects of these metals to young grapevines cultivated in these soils.
