RESUMEN.
Este trabajo fue realizado con el objetivo de caracterizar la diversidad vegetal del campo natural del palmar de Castillos (Rocha, Uruguay), identificar diferencias en la composición botánica dentro y fuera del palmar, determinar las especies que discriminan los dos ambientes y reconocer las potencialidades de los recursos genéticos y servicios ambientales. Mediante el uso del método de muestreo punto cuadrado, aplicado de dos formas (ocho transectas largas y 40 transectas cortas) se
determinó la presencia de 70 taxones. Los representantes de la familia Poaceae son el 57,1 % de los taxones, mayoritariamente perennes, con una relación C4/C3 de 1,6. Los análisis de agrupamientos y de componentes principales mostraron diferencias consistentes en la composición florística del estrato herbáceo del campo con palmas y sin palmas. Estas diferencias se atribuyen a la adaptación de las especies a condiciones de sombreado y mayor humedad del suelo, entre las
principales: Stenotaphrum secundatum, Pratia hederacea, Juncus spp., Hydrocotyle bonariensis, Paspalum urvillei, Paspalum proliferum y Plantago sp. El palmar provee de bienes de uso directo como forraje, sombra y abrigo para el ganado, producción de miel y recreación activa. Se reporta la utilización de un grupo destacado de recursos fitogenéticos de uso forrajero, medicinal y ornamental. |

The aim of this study was to evaluate the fatty acid composition of intramuscular fat and the vitamin E content of beef from different production systems. Four cattle production systems were used: cattle reared under intensive conditions and fed concentrate (INT1) from Spain, cattle raised at pasture and supplemented with concentrate (SUP1) from the United Kingdom, cattle raised at pasture and on corn silage (SUP2) from Germany and cattle reared under extensive conditions slaughtered at two and three years old (EXT2 and EXT3) from Uruguay. The highest proportion and content (mg per 100 g of muscle) of linoleic acid (C18:2n-6) and arachidonic acid (C20:4n-6) and the lowest saturated fatty acids (SFA) was found in INT1 beef. In contrast, beef reared under extensive conditions showed the highest proportion and content of linolenic acid (C18:3n-3), docosapentaenoic acid (DPA, C22:5n-3) and eicosapentaenoic acid (EPA, C20:5n-3), and SUP1 and SUP2 beef showed the highest level of palmitic acid (C16:0) and SFA. Beef from intensive system (INT1) had the lowest P/S (PUFA/SFA) ratio, whereas beef from extensive system (EXT2 and EXT3) had the lowest n-6/n-3 ratio. The results of the PCA (principal components analysis) of fatty acid composition showed that beef from intensive system (INT1) was clearly differentiated
from the other meats and was located with the C18:2n-6 and C20:4n-6 and the n-6/n-3 ratio. EXT2 and EXT3 beef were located with C18:3n-3 and long chain fatty acids. Beef from extensive systems had the highest concentration of vitamin E (3.91 mg a-tocopherol/kg muscle) MenosThe aim of this study was to evaluate the fatty acid composition of intramuscular fat and the vitamin E content of beef from different production systems.
