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.- Although the sensory characterization of mandarins has usually been performed by trained assessors, in recent years, the methodologies that depict sensory descriptions from the perception of consumers, such as the check-all-that-apply (CATA) questionnaires have become very popular. In this work, an exploratory study was first carried out using a focus group (FG) technique to determine attributes and aspects that influence the decision to purchase mandarins. Secondly, the consumer panel recruited 100 regular mandarin consumers that were randomly divided into two groups.

ABSTRACT.- A nodule-inhabiting Paenibacillus sp. strain (UY79) isolated from wild peanut (Arachis villosa) was screened for its antagonistic activity against diverse fungi and oomycetes (Botrytis cinerea, Fusarium verticillioides, Fusarium oxysporum, Fusarium graminearum, Fusarium semitectum, Macrophomina phaseolina, Phomopsis longicolla, Pythium ultimum, Phytophthora sojae, Rhizoctonia solani, Sclerotium rolfsii, and Trichoderma atroviride). The results obtained show that Paenibacillus sp.

ABSTRACT.- Long-term agricultural experiments (LTE) are essential to detect cumulative treatment effects on soil properties and to design sustainable production systems. However, to ensure high quality of long-term soil data and their correct interpretation, several analytical issues regarding the accuracy and analytical laboratory bias need to be considered.

ABSTRACT.- Context:Improving the partitioning of the energy consumed by dairy cows towards milk-solid production is a priority in grazing diary systems because energy efficiency has been associated with sustainability. Different selection criteria in the Holstein breed have led to divergent Holstein strains with different suitability to grazing systems.

Rice (Oryza sativa L.) systems rotated with perennial pastures have intensified in South America to increase annual grain productivity, but the effects on rice yield and soil quality remain poorly understood. We evaluated rice grain yield, crop and pasture biomass production, and soil organic carbon (SOC) and total nitrogen stocks (0?15-cm depth) in three rice-based rotations over 8 yr in Uruguay.

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
