Abstract:A series of trials were conducted in different experimental and feeding conditions to evaluate a purified and enriched lignin extracted from Eucalyptus grandis (LIPE®) as a marker to estimate faecal output in sheep fed temperate and tropical grasses.
Abstract: Characterization of the ovarian preantral follicle population is a necessary step to improve understanding of folliculogenesis and ovarian physiology. Therefore, in the present study, the preantral follicle population in the equine ovary in young and old mares was investigated according to follicular morphology, follicular class, distance from the geometric center using ovarian maps, and follicular density within ovarian portions (lateral vs intermediary) and regions (dorsal vs ventral).
ABSTRACT.- A telephone survey (n = 601) was conducted in Uruguay to explore participants? mental associations with meat and the underlying reasons changes in the quantity and type of meat consumed. Participants mentioned mostly positive associations with meat?s culinary and cultural aspects and its nutritional value as source of high-quality protein. Other associations were related to meat production, specific types of meat and cuts, meat consumption and pleasure, while price was perceived negatively.

Abstract: Aims:In this study, we sought to identify and characterize a collection of 101 lactobacilli strains isolated from natural whey starters used in Uruguayan artisan cheese production, based on their capacity to produce gamma-aminobutyric acid (GABA) and their probiotic potential. Methods and Results:The probiotic potential was assessed using low pH and bile salt resistance assays; bacterial adhesion to intestinal mucus was also evaluated. Selected strains were then identified by 16S sequencing, and their GABA-producing potential was confirmed and quantified using a UHPLC-MS system.
RESUMEN.- La aplicación de fertilizantes, asociada a la intensificación de la actividad agropecuaria, ha incrementado la pérdida de nutrientes desde los sitios de agricultura hacia los cuerpos de agua. Contar con coeficientes de exportación de nutrientes, específicos de los usos del suelo de cada sitio, es importante para cuantificar impactos sobre la calidad de agua.
ABSTRACT: The objective of this study was to assess hepatic ATP synthesis in Holstein cows of North American and New Zealand origins and the gluconeogenic pathway, one of the pathways with the highest ATP demands in the ruminant liver. Autumn-calving Holstein cows of New Zealand and North American origins were managed in a pasture-based system with supplementation of concentrate that represented approximately 33% of the predicted dry matter intake during 2017, 2018, and 2019, and hepatic biopsies were taken during mid-lactation at 174 ± 23 days in milk.
ABSTRACT.- In highly modified agricultural settings, it is now necessary to consider the management of plant diseases, insect pests and weeds within the One Health concept, to acknowledge that the health of plants, animals, environment and people are interlinked and interdependent. Articles included in this special issue of Sociedad Uruguaya de Fitopatología contribute to communicate scientific advances that will foster the sustainable management of diseases, pests and weeds in Uruguay and neighbouring countries.
ABSTRACT.- Performance-based funding and calls for public-funded science to demonstrate societal impact are encouraging public research organisations to evaluate impact, the so-called impact agenda. This paper explores evaluation methods of four fully or partially public-funded agricultural research organisations and how they are building evaluative capacity to respond to the impact agenda. Drawing on cross-organisational comparison of the readiness of each organisation to implement evaluation, the implications for improving evaluative capacity building (ECB) are discussed.
