Abstract:Herbicide resistance is currently one of the most important problems in agricultural systems, threatening their sustainability. In Uruguay, there have been increasing reports of herbicide failures to control LOLMU (Lolium multiflorum Lam.) populations. However, methodical characterization of herbicide resistance cases is lacking.

Hace unos dos años se temió por su desaparición. La primera experiencia de la Red Tecnológica Sectorial RTS había llegado a su fin y no aparecían recursos para poner a andar una segunda etapa. Se abrió un período de incertidumbre, gestiones y negociaciones que, recientemente, permitió alumbrar una segunda Red, con otro nombre, más abierta, corregida y mejorada, que genera auspiciosas perspectivas. Santiago Fariña, Director del Programa Nacional de Lechería, INIA, nos explica qué cambió y porque debemos aguardar mejores resultados.

ABSTRACT. - Composition and antioxidant properties of sixteen pecan [Carya illinoinensis (Wangenh) K. Koch] cultivars grown simultaneously in a single experimental orchard in Uruguay were evaluated to characterize their nutritional properties and nutraceutical potential. The percentage of oil, moisture, ash, minerals, and proteins were determined and also the fatty acid profile. Total phenolic compounds [18-41 mg gallic acid equivalents (GAEs)/g], condensed tannin [2-12 mg catechin equivalents (CEs)/g], and tocopherols (110-163 ?g/g) contents were estimated in nut kernels.

bstract:Yellow lamb disease is an infrequent disease in sheep for which there is scant literature, and that has been reported in the US, Australia, New Zealand, South Africa and Europe, although anecdotal evidence indicates that it may have also been diagnosed in South America. The disease is produced by some strains of Clostridium perfringens type A that produce unusually high levels of alpha- toxin. Because C.

ABSTRACT - The multiple sire system (MSS) is a common mating scheme in extensive beef production systems. However, MSS does not allow paternity identification and lead to inaccurate genetic predictions. The objective of this study was to investigate the implementation of single-step genomic BLUP (ssGBLUP) in different scenarios of uncertain paternity in the evaluation for 450-day adjusted liveweight (W450) and age at first calving (AFC) in a Nellore cattle population.
