RESUMEN.- Los sistemas silvopastoriles constituyen una modalidad de sistemas agroforestales basada en la producción integrada entre árboles,
plantas forrajeras y rumiantes. Cuando estos sistemas son bien planeados y conducidos, permiten explotar las sinergias entre los componentes, proporcionando ventajas económicas, para el bienestar animal y la prestación de servicios ambientales. La presencia de cubiertas arbóreas aumenta la humedad y posibilita una menor amplitud de variación térmica tanto del aire como del suelo, condiciones que mejoran el microclima para el crecimiento de plantas forrajeras y animales. La mayoría de los cultivos arbóreos establecidos en Uruguay son de alta densidad y destinados
prioritariamente para la producción de pulpa o madera para aserrío, condiciones que restringen la cantidad y calidad de radiación fotosintéticamente activa disponible para el sotobosque. De esa manera, no ocurre una satisfactoria producción de forraje a lo largo de los años, aspecto que determina que la integración con la ganadería sea temporaria. El objetivo de esta revisión es presentar el conocimiento generado en los sistemas silvopastoriles que se han establecido en Uruguay, sus aspectos críticos, experiencias internacionales y las oportunidades y desafíos para la investigación y transferencia de tecnología en Uruguay. Destacamos la necesidad de creación de sistemas planeados en forma conjunta con los destinatarios de esta tecnología y otras instituciones de investigación, fomento y desarrollo, para evaluar los diferentes componentes y sus interacciones en el largo plazo, además de determinar su impacto productivo y económico, valorando adecuadamente los posibles servicios ambientales. ------------------------------ SUMMARY.- Silvopastoral systems constitute a modality of agroforestry based on the integrated production between trees, forage plants and ruminants. When these systems are well planned and conducted, they allow to exploit the synergies between its components, providing economic benefits, better animal welfare and the provision of environmental services. The presence of tree covers increases humidity and allows a smaller thermal variation of both air and soil, conditions that improve the microclimate for the growth of forage plants and animals. Most of the tree crops established in Uruguay are constituted by high density plantations, destined for pulp or solid wood production,
conditions that restrict the quantity and quality of photosynthetically active radiation available for the understory environment. Therefore, there is no satisfactory forage production over the years, which determines that the system integration with livestock be only temporary. The objective of this review is to present the knowledge generated in silvopastoral systems that have been established in Uruguay, its critical aspects, international
experiences and the opportunities and challenges for research and technology transfer in our country. We highlight the need to create systems planned jointly with the recipients of this technology and other research and development institutions, in order to evaluate the different components and their interactions in the long term, as well as to determine their productive and economic impact at farm and region scale, and properly assessing the environmental impacts.

Abstract:
The relationships between ovulation rate and nutrition remain confused, probably because of uncontrolled variation in experimental conditions. To help resolve the problem, we analyzed data from 20 experiments conducted between 2002 and 2016, in Uruguay with grazing ewes. All experiments were carried out by a single laboratory under comparable conditions of experimental design and measured variables. The studies used a total of 3?720 ewes, of purebred Corriedale, Polwarth, or East Friesian x Polwarth genotypes. In all experiments, a control group grazed native pastures and extra nutrition was provided to the treatment groups using either improved pastures or supplements. Ovulation rate was measured by counting corpora lutea using laparoscopy or rectal ultrasound or by counting foetuses at ultrasound on day 45 of gestation. For statistical analysis, data were grouped according to nutritional treatment (control or supplemented) and, within these groups, type of supplement to provide energy or protein (protected or not from rumen degradation). Across all experiments, 92?99% of the ewes ovulated and the effects of diet, length of supplementation, and initial live weight and genotype are reported. Within diets, ovulation was most affected by overall energy intake during supplementation (P?0.01). Ewes that grazed native pastures supplemented with protein supplements had higher ovulation rates (P?0.05) than control ewes grazing only native pastures. The addition of tannins to the protein supplement, to protect it from degradation in the rumen, did not further increase the ovulation rate. In unsupplemented ewes that had access to legume pastures, ovulation rates did not increase when the legume pasture was rich in tannins although only ewes that grazed tanniniferous legumes had marginally higher ovulation rates than the control ewes (P?0.05). When ewes grazing native pastures were supplemented with energy, their ovulation rate did not increase above those of nonsupplemented ewes. Live weight at the start of supplementation also affected ovulation rate. We conclude that ovulation was most affected by overall energy intake, whereas the factors that affected ovulation rate during short-tern nutritional supplementation were intake of protein from highly digested supplements or dietary protein protected from ruminal degradation.
