RESUMEN. - La lechería en Uruguay representa un componente esencial, tanto desde lo económico como en lo cultural. Dentro de los datos de interés podemos mencionar que el 70% de lo que producimos se exporta, que somos el país de Latinoamérica con mayor consumo per capita de leche y sus derivados; y nos encontramos entre los primeros 12 países cuyas exportaciones de leche y derivados alcanzaron los valores más elevados durante el

Los sistemas arroz-ganadería disminuyen en forma significativa el área de pastoreo durante el verano debido a la presencia de los cultivos (arroz y soja) y a la realización de laboreos de verano para la próxima zafra de arroz. Esta situación se agrava a medida que el área de la rotación ocupa un porcentaje mayor del área total del sistema y que aumenta la intensidad agrícola de la rotación.

ABSTRACT.- This study evaluates nutritional and management strategies aimed at exploiting compensatory growth (CG) in weanling-to-beef systems in Uruguay. The evaluation encompassed productivity, economic viability, and environmental impact. The Grange Beef System Model, augmented with Uruguayan national technical coefficients, was used.

ABSTRACT. - Studies of oriental fruit moth (OFM), Grapholita molesta (Busck), and codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), both important pests of pome fruit, evaluated the addition of low-intensity light-emitting diode (LED) to delta traps baited with 3 commercial monitoring lures. Studies were conducted in 9 orchards treated with and without sex pheromone mating disruption for one or both species.

ABSTRACT. - Olive anthracnose caused by Colletotrichum spp. is the most important olive fruit disease worldwide. We hypothesize that induced water deficit in olive trees generates anatomical and biochemical changes which contribute to anthracnose fruit rot resistance. A three-year experiment was conducted in Arbequina under two irrigation treatments: fully irrigated (no water stress) and non-irrigated (moderate water stress), from pit hardening until harvest. At harvest, fruits were inoculated both in planta and in vitro with an isolate of C. acutatum s.l.

ABSTRACT.- The microbiota composition of the bovine female reproductive tract influences reproductive efficiency, susceptibility to genital pathogens, and the health of newborn calves. However, knowledge about cervico-vaginal microbiota during gestation is scarce. Therefore, the present study aimed to analyze the taxonomic profile of the cervico-vaginal bovine microbiota throughout pregnancy and after calving using high-throughput sequencing of a fragment of the 16S ribosomal RNA gene.

ABSTRACT.- Stockpiling forage (i.e., deferring grazing) is one way to provide forage for livestock during intervals of low pasture growth, but there are trade-offs as nutrient content declines with increasing forage maturity. Phosphorous (P) concentration, crude protein (CP) content and organic matter digestibility (OMD) were evaluated in two C3 and four C4 grasses native to the South American Campos grasslands.

ABSTRACT.- We estimate the implicit market price of soil erosion using quarterly data of 2824 agricultural farms traded in Uruguay between 2000 and 2014.Aunique feature of our estimation is that we allow for possible spatial spillovers. We find evidence of a negative and statistically significant association between erosion and land values. On average, an additional loss of 1% of the original topsoil due to erosion is associated with a direct (own) decrease of .24% in the per-hectare price of agricultural land (P-value: .012, 95% CI: -.0042, -.0005).

ABSTRACT. - The demand for animal protein is rising, increasing pressure on animal production systems and ecological resources. Ethical and environmental concerns are also growing worldwide, pushing for more sustainable food production systems. The international scientific community has raised concerns about misinformation regarding meat production processes and their harmful impact on the environment, animal welfare and human health consumption.
