Históricamente, nuestra ganadería ha jugado un papel protagónico como soporte de la economía nacional. Sin embargo, el funcionamiento actual del mercado ganadero lleva menos de tres décadas. En un mercado competitivo, las señales deberían transmitirse vía precios a través de la cadena de comercialización, desde el producto final "carne" hasta el del ternero. Verificar si esto efectivamente ocurre, es el objetivo de esta investigación. He aquí los primeros resultados.

La Unidad Experimental "Glencoe" celebró el pasado 29 de setiembre sus 50 años. Se realizó una recorrida de campo con 3 paradas: 1.- Herramientas para la intensificación sostenible de la ganadería: mejoramientos de campo con Lotus INIA Basalto, genética animal y suplementación infrecuente restringida. -- 2.- Entretejiendo innovación e investigación: las lanas finas. -- 3.- Experimento de largo plazo: sistemas de pastoreo sobre campo natural.

ABSTRACT.- Ensifer (syn. Sinorhizobium) meliloti U143 is an effective nitrogen-fixing strain isolated from Uruguayan soils. For decades, this strain has been used as an inoculant for different alfalfa cultivars. Here we report for the first time a characterization of the U143 elite strain that includes the preliminary genomic sequence, its annotation, and physiological parameters related to its symbiotic efficiency and nitrate respiration capacity. Through Illumina sequencing, the genome of the U143 strain was sequenced.

Defoliation management is determinant of forage production and plant persistence. The objective of this study was to identify grazing suitability and stability of herbage production of INIA Sepé subjected to four intensities of defoliation (represented for sward canopies of 3, 10, 17 and 24 cm maintained constant through weekly cuts) and two rates of nitrogen fertilization (100 and 300 kg ha-1).

ABSTRACT.- Eucalyptus is one of the mainstays of the forest industry, contributing high-quality raw materials for pulp, paper, wood, and energy production. The typical approaches to reveal the genetic basis of important traits include classical Quantitative Trait Locus (QTL) mapping and Genome-Wide Association Studies (GWAS) approaches, but these are typically expensive and time-consuming. Here we evaluate the potential of Extreme-Phenotype GWAS (XP-GWAS) to identify candidate genes underlying a quantitative trait in Eucalyptus, using the timing of leaf heteroblasty as a case study.
