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.- 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.- 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.- 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.- Sorghum-associated arthrogryposis and axonopathy is a rare congenital condition reported in ruminants and horses. Here, we describe the epidemiologic, clinical, and pathologic aspects of nine outbreaks of this condition in beef cattle in midwestern and southeastern Brazil (2014-2023). These regions are the most productive grain sorghum areas, where livestock producers use the straw extensively, producing a high regrowth during drought periods. All the affected pregnant cows had grazed sorghum stover for periods ranging from 25 days to 4 months.

ABSTRACT.- The development of metrics to assess the sustainability of food production systems is vital for achieving sustainable global agri-food systems. Nitrogen use efficiency (NUE), defined as the ratio of nitrogen (N) in food outputs to total N inputs, is a key indicator of resource efficiency in crop and livestock systems.

ABSTRACT.- In Brazil, CNS diseases in equids were little known until the 1980s. Since then, several diagnostic laboratories have been operating in different universities, initially in the South and Southeast regions and, later, in the Central-West, Northeast and North regions. However, the knowledge accumulated from the diagnoses of nervous system diseases of equids made at these institutions over the years has not been reviewed comprehensively, and many papers are published in Portuguese.

RESUMEN.- Se evaluó el estado estructural del suelo en distintos sistemas agrícolas y agrícola-pastoriles mediante la metodología del Perfil Cultural. Se consideraron las estructuras de origen antrópico relacionadas al uso y manejo del suelo y a la actividad biológica en el perfil. La evaluación abarcó la proporción de dichas estructuras
