ABSTRACT.- The rising demand for sustainably and ethically produced alternatives to animal protein-rich foods has driven interest in plant-based meat analogues. This study evaluated the potential of lupin flour (LF), protein isolate (LPI), and their blends with soy protein isolate (SPI) to produce high-moisture meat analogues (HMMAs) through extrusion cooking. Six SPI-LF-LPI blends, with protein contents ranging from 64.5% to 80.5%, were extruded under three feed moisture contents (FMC) of 60%, 65%, and 70%.

ABSTRACT.- Rice (Oryza sativa L.) is a staple food for over half of the world's population. With population growth, socioeconomic changes, and shifting consumer lifestyles, the demand for high-quality rice has surged. Understanding consumer preferences for rice quality traits is crucial for breeders to effectively address evolving market needs. Rice breeding programs assess various quality aspects, including grain shape, appearance, milling efficiency, and cooking and eating qualities.

ABSTRACT.- Understanding herbivore interaction with forage resources is crucial for effective grazing management. This study investigates the impact of sward management strategies on the foraging behavior of sheep under continuous stocking. Italian ryegrass pastures were maintained at an average sward height of 15 cm, which has been reported to be optimal for animal performance. The objective was to assess whether sheep modify their grazing behavior in response to different interventions to maintain the target sward height.

ABSTRACT.- Protists are one of the most diverse major eukaryotes in the soil ecosystems and play essential functional roles in shaping the microbial community structure, soil nutrient cycling, and crop productivity. However, protist community composition in soils is poorly understood, notably in paddy field soils with alternating oxic and anoxic phases and when under rotation with other crops and pastures. Furthermore, current knowledge about South American soils' protist communities is limited.

ABSTRACT.- Effective planning and decision-making for rice (Oryza sativa L.) cultivation require precise yield predictions. Thus, new prediction strategies that incorporate climatic effects and management variables are essential to bridge the gap between actual and potential yields. This study aimed to evaluate the predictive accuracy of rice yield under real production conditions, considering weekly climatic information. The specific focus was on identifying which factors contribute to improved predictive performance and when they play a critical role in the production cycle.

ABSTRACT.- Toxoplasmosis, caused by the obligate intracellular parasite Toxoplasma gondii, is one of the most prevalent zoonotic parasitic infections worldwide. When acquired during pregnancy, T. gondii can be transmitted to the fetus, with clinical outcomes influenced by gestational age at time of infection and the parasite's genotype. Prenatal screening enables the detection of maternal seroconversion and offers a critical window for intervention. In Uruguay, despite mandatory serological screening during pregnancy, national data on T.

ABSTRACT.- Herbicide resistance in Conyza bonariensis (hairy fleabane) poses a significant challenge to agricultural systems worldwide. The genetic variability and prolific seed production of this species contribute significantly to its adaptative potential and fast spread in the agricultural fields. This study aimed to investigate the mechanisms underlying multiple herbicide resistance to glyphosate and ALS inhibitors in C. bonariensis biotypes from southern Brazil. Resistance factors exceeded 100 times for chlorimuron-ethyl and 49 times for glyphosate.

ABSTRACT.- Introduction: Varroa destructor stands as the primary global pest of honey bees, inflicting direct harm on bees while also acting as a vector for a multitude of viruses. Integrated pest management is widely recognized as the optimal strategy for minimizing acaricide application. Designed bottom boards that can limit the growth of the mite population by removing them from the hive and preventing their return and reinfestation of the colony show promising potential.

ABSTRACT.- Group A rotavirus (RVA) infections are a leading cause of neonatal diarrhoea in foals. Neonatal mice could serve as a useful tool to study the pathogenesis of equine RVA (ERVA) as well as a preclinical model for assessment of vaccine efficacy. This study aimed to comparatively evaluate the clinical, virological and pathological features of ERVA G3P[12] and G14P[12] infection in neonatal mice and compare them with porcine OSU G5P[7] and bovine UK G6P[5] RVA reference strains.

ABSTRACT.- Bromus auleticus is a perennial grass native to the campos of South America, valued for its persistence, productivity and forage quality. Conservation and breeding efforts are constrained by limited knowledge of its reproductive aspects. Although allogamy and genetic incompatibility have been reported, these traits have not been sufficiently corroborated across multiple populations. This work aimed to determine the reproductive system of B.
