Este trabajo, tiene como objetivo compartir experiencias de investigación y desarrollo que buscan hacer uso de las oportunidades y agendar los desafíos, pudiendo agregar valor a la producción (y a la cadena de valor), atendiendo aspectos de las personas, los animales, y el ambiente.
En los últimos 15 años se ha generado en Uruguay un importante cúmulo de información asociada al valor genético de los animales y cómo la utilización de animales "superiores" impacta favorablemente en los sistemas de producción. A nivel nacional, los programas de evaluación genética ovina han estado focalizados en las variables productivas que impactan en el ingreso económico del sistema (ej. diámetro de la fibra, peso de vellón y peso corporal).
Merino breed in Uruguay:The Merino breed was introduced to Uruguay in the 19th century (1875) when a family of Basque-French immigrants arrived in the country with their flock. In 1901, the first pedigree imports were recorded in the Rural Association of Uruguay (ARU, 2021). Imports of pedigree animals from Argentina began in 1903, in 1911 from the USA and in 1924 the first rams were imported from Australia. The Australian variety was imported to Uruguay through two English companies based in Argentine Patagonia.
Improving sheep resilience could be a strategy to increase production, adaptability, and sustainability (social, economic, and environmental) under an agroecological transition. The objective of this paper is to discuss how animal breeding can contribute towards improving sheep resilience.
Introduction:Shiga toxin-producing Escherichia coli (STEC) is a zoonotic pathogen that cause food-borne diseases in humans. Cattle and derived foodstuffs play a known role as reservoir and vehicles, respectively. In Uruguay, information about the characteristics of circulating STEC in meat productive chain is scarce. The aim was to characterize STEC strains recovered from 800 bovine carcasses of different slaughterhouses. Methods:To characterize STEC strains we use classical microbiological procedures, Whole Genome Sequencing (WGS) and FAO/WHO risk criteria.
ABSTRACT.- Ergot disease (Claviceps paspali) and sterility have the potential to reduce seed yield in bahiagrass (Paspalum notatum Fluggé). Our objective was to determine the genotypic and environmental effects on seed yield, and the levels of ergot and sterility. Seventeen genotypes were evaluated in three locations across two years for seed yield, ergot severity, and total seed fractions (percentage of full seeds, ergot sclerotia and empty seeds).
