Even though farms have technical capacity to frequently apply nutrients and irrigation according to crop demand, potassium (K) and nitrogen (N) supply and the hydric welfare index were the most important limiting factors responsible of greenhouse tomato yield variability in Uruguay
Final Comments:
- Genetics: improvement (yield, oil). - Diseases: low incidence of Phoma lingam.
- Low shattering: direct harvest. - Meal: it can be used for animals in mixtures. - Plague birds:- not a problem.
- Brassicas: Carinata and Canola should complement wheat and barley area for a sustainable rotation in agriculture.

Improving feed efficiency is a key factor in livestock systems to reduce feeding costs and enhance profitability [1], and it is also associated with beef production sustainability. Residual feed intake (RFI) is one of the methodologies for calculating feed efficiency of growing beef cattle, which is a moderately heritable characteristic enabling genetic improvement through selection [2]. However, literature is not entirely conclusive about the effect of RFI genetic selection on beef quality.
The first Uruguayan Beef Quality Audit (UBQA) was conducted in 2002, in a joint project among Colorado State University, INAC e INIA and was an important benchmark to identify what the beef industry was producing, measuring and reporting on cattle and carcass traits. Seven National Beef Quality Audits (NBQA) were conducted in the U.S. (1991, 1995, 2000, 2005, 2011, 2016 and 2022), and four in Uruguay (UBQA 2002, 2007, 2013 and 2022). Many of the UBQA findings were used as training practices for producer and packers related to animal handling.
Aging is a post-mortem practice for beef tenderization and flavor improvement. Wet and dry aging are the most common processes to age beef. Dry aging in a highly moisture-permeable bag has been widely used in the last decades, producing dry-aged products mainly to reduce microbial
La selección genética es una herramienta clave para fortalecer la sostenibilidad económica, social y ambiental de la ganadería, con impacto acumulativo y permanente. Actualmente, el sector enfrenta el desafío de reducir las emisiones de metano entérico producido por los rumiantes.
La pérdida de biodiversidad en el Antropoceno alcanza tasas similares a la última extinción masiva, afectando el ambiente drásticamente. En Uruguay, a fines del siglo XX, el uso del suelo cambió significativamente debido al avance de la forestación y la producción de soja.
Introduction: Resilient animals are minimally affected by environmental disturbances. When affected, they can return quickly to the state that was previous to the disturbance (Colditz & Hine, 2016). To test this hypothesis, we attempted here to measure the relationship between resilience traits in lambs from the Uruguayan Texel breed.
