| During a 12-month study, bulk-tank milk was collected once a month from organic (O) (n=3) and conventional semi-extensive (CSE) (n=5) ewe’s dairy farms in the Castile and León region (northwest Spain). CSE is the most similar conventional production system to the organic one because they are both part-time grazing system. Milk samples were analysed for retinol, -tocopherol and -tocopherol. The production system and the sampling month affecting the milk fat vitamin content were investigated. Results show that organic ewe’s milk showed significantly higher contents of -tocopherol and -tocopherol and consequently of total tocopherol possibly due to the higher green pasture intake (1,02 vs 0.48 kg sheep-1 day-1) and the lower milk yield (53.5 vs 88.7).... |

| Sustainability is a concept developed from economic, ecological and social strategies in the decision-making process. Quality of life and quality of work life are two indicators very related to the viability and sustainability of farms. They are located into the social sustainability but in some cases the production system affects all three aspects of sustainability and transcends into a lifestyle. Organic production in several small ruminant farms analyzed in Spain provides quality of life and quality of work significantly better than conventional ones. |

| Samples of suckling lambs (n=40) of two breeds reared under conventional and organic conditions were analysed to asses physico-chemical characteristics, including instrumental texture, and nutritional quality in terms of fatty acid composition. Consumer acceptance was also studied using the home-use test. Results revealed that organic suckling lamb meat is healthier as shown by the lower saturated fatty acid levels, the higher polyunsaturated fatty acid contents and the higher 6/3 ratiko. The organic meat had lower instrumental hardness, received higher scores in all sensory parameters, and had statistically better fat sensation and higher ratings for overall liking. These results lend support to the notion among consumers that organic products are... |

| 40 L. dorsi muscles from the left half carcass of suckling lambs raised under both organic and conventional systems were evaluated by a sixteen-member trained panel, following QDA methodology. After developing a common vocabulary for the evaluation of characteristics, 30 meat descriptors in raw and grilled meat were selected. Additionally,overall appreciation was evaluated by 140 consumers in a home-use test. The results obtained show that the appearance of the organic meat was more fibrous, darker, and with a lower aroma intensity than the conventional counterpart, but with no differences in homogeneity or juiciness. In grilled meat, the organic samples had less subcutaneous fat,less fatness, a less fibrous texture and less aroma intensity, but also less... |

| In the Mediterranean Agriculture, the organic production constitutes a real possibility for sustainable development, it can keep a population in these areas and provide it with a decent work. This paper try to establish differences between conventional and organic systems of production, so that observation of these differences would lead to conclusions relating to the level of efficiency of one system as against the other. To achieve this objective, the research team analyzed the evolution of seventeen milk sheep farms in various places in the Castilla y León Region for a whole year. The study consisted in the modeling of the results of a Cobb-Douglas production function. The findings reveal that organic farms have higher production levels with the same... |

| Carcass characteristics of sucking lambs (n= 40) of two breeds reared under conventional and organic conditions were analysed including objective and subjective parameters for fatness and conformation, meat and fat colour. Consumer acceptance was also studied using the home-use test. Results showed that the characteristics of the carcass of suckling lamb were similar for both types of production systems pointing out that organic production system did not affect fatness or muscle development. However, organic meat was darker (higher L* and a* values) probably related with the higher amount of exercise, although fat was not more yellow. In contrast consumers did not consider organic meat darker and there were not significant differences in appearance related... |
