ABSTRACT. This study aimed to describe the first report of an outbreak of primary photosensitization in dairy goats caused by Froelichia humboldtiana. The disease occurred from March to May 2014, in a mixed flock of 15 Saanen, Alpine, and crossbred lactating goats. The entire flock was affected; however, the Saanen and cross-bred goats developed more severe lesions, and their milk production decreased by as much as 75%. Lesions were progressive and consisted of skin hyperemia, edema, and necrosis, especially in depigmented areas.

ABSTRACT. Cyrtobagous salviniae is widely used in several countries including the United States, South Africa and Australia for biological control of Salvinia molesta Mitchell (Salviniales:Salviniaceae). Despite considerable success in tropical and subtropical regions, the effectiveness of C. salviniae on S. molesta is inconsistent in temperate regions, indicating the need for populations adapted to cooler climates. The objectives of this study were to determine the regions of South America that are climatically similar to S.

RESUMEN: Actualmente se acepta que el manejo sustentable de malezas de campo natural debe estar comprendido en una estrategia general de manejo de la vegetación. En ella, la supresión de la/s maleza/s debe complementarse con la promoción de las especies deseadas. Desde esta perspectiva, la cuantificación del éxito del control trasciende la reducción de la abundancia de la maleza a corto plazo.

Abstract. Background:Porcine circovirus 2 causes different clinical syndromes resulting in a significant economic loss in the pork industry. Three pigs with unexplained cardiac and multi-organ inflammation that tested negative for PCV2 and other known porcine pathogens were further analyzed. Methods:Histology was used to identify microscopic lesions in multiple tissues. Metagenomics was used to detect viral sequences in tissue homogenates.

En el marco de la Expo Nacional Merilín y ante la presencia de cabañeros y productores, se realizó en la Asociación Rural de Tacuarembó una presentación del trabajo conjunto que la Sociedad de Criadores de Merilín, el INIA y el SUL vienen realizando sobre el desarrollo de un nuevo biotipo doble propósito (fino y prolífico) denominado Merilín PLUS. Durante la jornada se presentó información sobre las características de este desarrollo que busca combinar las fortalezas de las razas Merilin (50%), Merino Australiano (25%) y Finnsheep (25%), para alcanzar objetivos de mercado y adaptarse a las
