In the present work it is studied the predictive ability of NIRS for the estimation of chemical composition (n = 81) and organic matter digestibility (n = 52) of permanent and temporary pasture hays, being developed empirical equations based on chemical parameters to estimate the organic matter digestibility (OMD) values and compared the predictive ability of empirical models vs. NIRS equations. The collections of sam-Pereira-Crespo with standards of known in vivo digestibility (n = 38 samples). The predictive ability of the NIRS models for estimating the OMD and chemical composition ranged from excellent to good, according with the observed coefficient of determination in cross-validation (1 – VR) , higher than 0.90, except for the organic matter content (1 – VR = 0.87), whilst the ratio of the standard deviation of the original data to standard error of cross-validation ( RPD ) values were higher than 3.0 for all the parameters studied. Appl-ying NIRS models to the prediction of OMD of hay led to the reduction by half of the standard error of cross-validation ( SECV ) of the best empirical models, from ± 3.9 % to ± 1.9 %. It is concluded that the NIRS models developed in the present work as a tool for the rapid and precise nutritional evaluation of hay used in Galician dairy farms and can be satisfactorily used in routine analysis.

Rioja and Ribera del Duero are two of the most important wine PDOs in Spain considering the value in euros of their annual production, as well as the prestige of their wineries and wines. The wineries of both PDOs compete in the globalized market, taking advantage of their distinctive resources and capacities, and developing strategies that allow them to differentiate themselves and earn a place in the market. However, what remains unknown are what are these differentiating resources and capabilities, and what are the strategies that characterize each of these successful competition models. This article addresses the analysis from a novel point of view, from the study of its resources and capabilities and its interaction with the strategy. With respect to resources and capabilities we focus on innovation, and on strategy in the Robinson and Pearce model. Through the analysis of 69 wineries of these two PDOs, the results show how the competitive situation and resources influence the strategy developed by the wineries. It is verified how the wineries combine resources and strategies, and how they balance their competitive position by strategically developing those resources in those that are less competitive.
Rioja和Ribera del Duero是西班牙最重要的两个葡萄酒PDO，考虑到其年产量的欧元价值，以及其酒庄和葡萄酒的声望。两家PDO的酒庄都在全球化市场中竞争，利用其独特的资源和能力，制定战略，使其能够脱颖而出，并在市场中赢得一席之地。然而，仍然未知的是，这些差异化的资源和能力是什么，以及这些成功竞争模式的特点是什么。本文从一个新的角度，从研究其资源和能力以及与战略的互动来进行分析。在资源和能力方面，我们专注于罗宾逊和皮尔斯模式下的创新和战略。通过对这两个PDO的69家酒庄的分析，结果显示了竞争形势和资源如何影响酒庄制定的战略。验证了酿酒厂如何将资源和战略相结合，以及如何通过在竞争力较低的地区战略性地开发这些资源来平衡其竞争地位。
