Abstract: Aim of study:This study evaluated the effect of the application of liquid aerobic treated manure (continuous liquid composting, CLC) on physical, chemical and biological soil properties, with the objective of monitoring changes induced by soil management with CLC as a biofertilizer. Area of study:Colonia, Uruguay (lat. 34,338164 S, long.

ABSTRACT. An outbreak of acute febrile syndrome associated with coagulopathy and severe pancytopenia occurred in cattle grazing in paddocks with high infestation by Adiantopsis chlorophylla. The administration of the plant to a calf reproduced the same signs and lesions seen in spontaneous cases. Similar syndromes are caused by ptaquiloside from bracken fern. Traces of the ptaquiloside-like molecule caudatoside were detected together with 0.03?0.24 mg/g of it's degradation product pterosin A, in dry fronds of the plant. In conclusion, A.

ABSTRACT. The genomic measure of inbreeding is closer to the actual inbreeding than the pedigree-based measure. However, it cannot be computed for ungenotyped animals. An estimate of genomic inbreeding comes from the diagonal of matrix H used in single-step methods. This matrix projects genomic relationships to all ungenotyped members of the pedigree. The diagonal element of H−1 gives an estimate of the genomic inbreeding coefficient. However, so far no computational methods are available to compute the diagonal of H. Here we propose 3 exact methods to compute this diagonal.

ABSTRACT. The photosynthesis process is determined by the intensity level and spectral quality of the light; therefore, leaves need to adapt to a changing environment. The incident energy absorbed can exceed the sink capability of the photosystems, and, in this context, photoinhibition may occur in both photosystem II (PSII) and photosystem I (PSI). Quantum yield parameters analyses reveal how the energy is managed.

ABSTRACT. Yield gap analysis is a powerful method to explore gap?s breadth between potential yields, attainable and those realized in farmers? fields, identifying constraints to production and assess opportunities to yield increase. We assessed yields and yield components across two seasons, in 110 greenhouse tomato (Solanum lycopersicum) crops during 2014/15 and 2015/16 in the south region of Uruguay, and compared them with potential and attainable yield.

RESUMEN: La estabilidad de agregados (EA) es determinante de la susceptibilidad del suelo a la erosión y compactación.Con el objetivo de evaluar el impacto de las propiedades físico-químicas en la EA de Molisoles, se seleccionaron 16 sitios, de diversa composición físico-química, en los cuales se determinó la EA mediante la técnica de Le Bissonnais. Un alto porcentaje de la variabilidad de la EA se debió al contenido de arena, Mg y Carbono.

ABSTRACT. Optical sensors can be used to assess crop N status to assist with N fertilizer management. Differences between cultivars may affect optical sensor measurement. Cultivar effects on measurements made with the SPAD-502 (Soil Plant Analysis Development) meter and the MC-100 (Chlorophyll Concentration Meter), and of several vegetation indices measured with the Crop Circle ACS470 canopy reflectance sensor, were assessed. A cucumber (Cucumis sativus L.) crop was grown in a greenhouse, with three cultivars.

ABSTRACT. After harvesting, barley grains (Hordeum vulgare L.) can show dormancy and water sensitivity, which delays industrial use. Both effects depend on the barley genotype and environmental conditions during grain maturation. In order to analyze the effect of the average temperature and the total rainfall accumulated during and in the final third of the grain filling, on the dormancy and water sensitivity and the relationship between them, three cultivars of barley were sownin four dates in 2009 and two in 2011.

ABSTRACT. Infection by Rhodococcus equi is considered one of the major health concerns for foals worldwide. In order to better understand the disease?s clinical and pathological features, we studied twenty cases of natural infection by R. equi in foals. These cases are characterized according to their clinical and pathological findings and immunohistochemical aspects. Necropsy, histologic examination, bacterial culture, R. equi and Pneumocystis spp. immunohistochemistry were performed.
