ABSTRACT.- The objective of this study was to compare the behavioural and immunological responses of twin lambs housed together with their siblings or not after weaning. The study was performed with seven multiparous Milchschaf ewes and their twin lambs (n = 14), which were weaned abruptly at 63 days of age and assigned to two experimental groups:(1) lambs that were housed together with their sibling after weaning (group GT, n = 6) and (2) lambs that were separated from their siblings and remained with other lambs from the same flock (group GS, n = 8).

ABSTRACT.- Prevention of the development of chronic diseases related to metabolic syndrome has been found to depend on a healthy diet. Among healthy foods, fruits and vegetables play a very important role due to their nutrient content, especially antioxidants, vitamins and polyphenols. For 20 years, INIA has promoted the concept of quality asso-ciated to the differentiation of products in the fruit and horticultural sectors, considering aspects not only linked to the organoleptic qualities, but also the production processes that ensure food safety and nutritional contribu-tion.

En adhesión al Año Internacional de las Frutas y las Verduras, y reafirmando su importancia, Agrocien-cia Uruguay decide publicar una edición especial con trabajos referidos a los principales desafíos en la producción, la comercialización y el consumo de frutas y hortalizas en Uruguay.La definición de Naciones Unidas tiene como obje-tivo sensibilizar, atraer la atención de las políticas y compartir las buenas prácticas en relación con:los beneficios nutricionales del consumo de frutas y verduras; la contribución de estas a dietas y estilos de vida diversificados, equilibrad

Las Naciones Unidas declararon el año 2021 como el Año Internacional de las Frutas y Verduras. Agrociencia Uruguay consideró oportuna la edición de un número especial conmemorando esta iniciativa y contribuyendo a la difusión de información científica sobre el aporte de estos cultivos y alimentos

ABSTRACT.- The expansion of olive orchards into regions with no tradition of olive production and humid climates, such as Uruguay, with more than 1200 mm of annual rainfall, calls into question the need for irrigation. In these regions, however, years with water deficit during summers are quite common. The vapor pressure deficit during summer is lower than in countries with a Mediterranean climate.

ABSTRACT.- Diversification of rootstock varieties, with consequent reduction in phytosanitary risks, has great importance to the sustainability of citrus cultivation in the south of Brazil. This study evaluated the performance of 42 rootstocks in the nursery phase to generate ?Valencia Late? sweet orange seedlings. Therefore, nucellar seedlings from the rootstocks under study were analyzed in relation to plant height, stem diameter, mortality rate and percentage of bud set after grafting. The experimental design was completely randomized with four replications of 20 sample units.
