Genetic selection has been a key tool for improving productive performance in small ruminant populations around the world, especially in Europe. This has been achieved through selective breeding for numerous traits, using diverse genetic evaluation systems and breeding schemes. Knowledge of the alternative approaches taken is paramount to the design of efficient and integrated genomic breeding programs. In this study, we summarised information on 48 sheep and goat breeding programs, genetic and genomic evaluation systems and resources available in 12 countries involved in the SMARTER project. This was done using published reports and surveys distributed to all partners. Responses to the surveys reveals information for more than 9, 16, and 20 dairy goat, dairy sheep, and meat sheep breeds involved in genetic schemes, respectively, with ~3,083,562 animals included in data collection schemes. The main groups of traits recorded across countries are: (1) milk yield and composition, mastitis indicators, udder and
body conformation, and reproduction in dairy sheep and dairy goats; and (2) growth, reproduction, health, ultrasound, wool, and carcass in meat sheep. Seven countries have progeny testing schemes, but only 5 use artificial insemination. There are numerous challenges to be addressed (e.g. disparity of trait recording, SNP panels, statistical models used, joining pedigrees across countries as well as grouping breeds based on genetic similarity, and an average of ~30% of animals with unknown sires). However, there are many opportunities to use the current resources and develop collaborative approaches to optimise selection for novel breeding goals such as resilience and efficiency in small ruminants across countries.

RESUMEN.
Para evaluar el uso potencial de las cianobacterias fijadoras de nitrógeno con heterocistos como biofertilizantes naturales para el cultivo de arroz en Uruguay, se estudió su diversidad, cantidad y variación a lo largo del ciclo de cultivo en Paso de la Laguna (Treinta y Tres). Se comparó la diversidad y densidad de cianobacterias con heterocisto en distintos tratamientos: sin urea inoculado con cianobacterias, con urea sin inocular y un testigo sin nitrógeno y sin inocular. El inoculante comercial, mezcla seca de Nostoc sp. y Tolypothrix tenuis se aplicó al doble de la dosis recomendada. Al tratamiento que se pretendía libre de cianobacterias, se le agregó CuSO4 (2,5 K/ha). Alrededor del 90% de las cianobacterias con heterocisto encontradas en todos los tratamientos correspondieron a los géneros Anabaena y Nostoc. Anabaena fue el género dominante en el testigo y Nostoc en
el resto de los tratamientos. Los géneros menos abundantes fueron Calothrix, Cylindrospennum, Nodularia, Scytonema y Tolypothrix. Colonias macroscópicas de Gloeotrichia sp. aparecieron doce semanas después de la inundación en todos los tratamientos . . La mayor cantidad de cianobacterias, 1,6 x 105 UFC/cm2 de suelo, se encontró en el testigo ocho semanas después de la inundación. En ese momento se encontraron los mayores valores de UFC/ cm2 de suelo en todos los tratamientos. La aplicación de urea en cobertura y la inoculación se asociaron con un menor número cianobacterias, 1,6 y 1 x 104 UFC/cm2, respectivamente.

SUMMARY.
To evaluate the potential use of nitrogen-fixing heterocystous cyanobacteria as natural biofertizer for rice in Uruguay, the diversity, abundance and variation of these microorganisms along the crop cycle were studied at Paso de la Laguna (Treinta y Tres). Diversity and population density ofheterocystous cyanobacteria were compared
between a treatment without urea inoculated with cyanobacteria, other with urea application and without inoculum and a control without nitrogen and inoculum. The comercial inoculum used, dry mixture of Nostoc sp. and Tolypothrix tenuis, was applied at two-fold the recommended dosis. CuS04 (2,5 K/ha) was added to the control treatment pretending to reduce the native cyanobacterial population. About 90 % of the heterocystous cyanobacteria found in all treatments belonged to the genera Anabaena and Nostoc.
Anabaena was the dominant genus at the control treatment and Nostoc at the rest of the treatments. The less abundant genera were Calothrix, Cylindrospennum, Nodularia, Scytonema and Tolypothrix. Macroscopic colonies of Gloeotrichia sp. appeared in all the treatments twelve weeks after irrigation started. The highest value of cyanobacteria,
1,6 x 105 CFU!cm2, was found at the control 8 weeks after the irrigation started. At this time ofthe crop cycle, the highest cyanobacterial numbers were found in all the treatments. The broadcasted application of urea and the inoculation were associated with less cyanobacterial density, 1,6 y 1x104 CFU/cm2, respectively. MenosRESUMEN.
