“…To optimize the accuracy of calibration, several mathematical pre-treatments were applied, namely multiplicative scatter correction (MSC) and standard normal variate (SNV), with or without the de-trending (DT) option, for the correction of scatter effects in the spectra [23]. Furthermore, two derivative mathematical treatments of the log 1/R were tested in order to optimize the extraction of useful information from the spectra: Savitzky-Golay (2, 10, 9), second order derivative, 10 smoothing left side points, and 9 smoothing right side points; and Savitzky-Golay (1,11,15), first order derivative, 11 smoothing left side points, and 15 smoothing right side points [24]. All calibrations were evaluated in both the full NIR spectra and those reduced into specific regions for each test (1, 2, 3, and 4).…”

“…The increasing consumer demand for meat products derived from autochthonous breeds reared in extensive systems may be due to the positive perception of society towards these breeds, regarding the conservation of the environment and animal welfare [1,2], as well as their high quality products in terms of organoleptic, health, and sensory features [3].…”

Autochthonous pig breeds provide products of differentiated quality, among which quality control is difficult to perform and insufficient for current market requirements. The present research evaluates the predictive ability of near-infrared (NIR) spectroscopy, combined with chemometric methods as a rapid and affordable tool to assure traceability and quality control. Thus, NIR technology was assessed for intact and minced muscle Longissimus thoracis et lumborum samples collected from 12 European autochthonous pig breeds for the quantification of lipid content and fatty acid composition. Different tests were performed using different numbers of samples for calibration and validation. The best predictive ability was found using minced presentation and set with 80% of the samples for the calibration and the remaining 20% for the external validation test for the following traits: lipid content and saturated and polyunsaturated fatty acids, which attained both the highest determination coefficients (0.89, 0.61, and 0.65, respectively) and the lowest root mean square errors in external validation (0.62, 1.82, and 1.36, respectively). Lower predictive ability was observed for intact muscles. These results could contribute to improve the management of autochthonous breeds and to ensure quality of their products by traditional meat industry chains.

“…In fact, in late autumn, when the acorns from the oaks ( Quercus ilex ) and cork oaks ( Quercus suber ) fall, pigs eat only the acorns and other natural products like tubers, grasses, legumes, fungi or roots from the dehesa pastures ( 4 ). This late fattening phase at La Dehesa is called “montanera” and the pigs must gain their last 50 kg−60 kg based only on that type of food source ( 5 ). In fact, pigs feeding freely during the montanera season are regarded as a distinctive mark of the best quality Iberian pig products ( 6 ).…”

Sex Differences in Group Composition and Habitat Use of Iberian Free-Range Pigs

The aim of the present work was to study group size, group composition and habitat use of Iberian pigs along the year when reared outdoor. This consists of a regimen in which animals are reared free range from 2 months of age until at least 14 months of age. In a first stage, animals are supplemented with concentrates, and in a second, called montanera, pigs eat just natural resources in areas with no more than two pigs per hectare. In these systems, males are castrated to avoid boar taint and females spayed to avoid the attraction and mounting by wild boars. The study was carried out in five different farms allocated in the south-west of Spain during 2 consecutive years, from March 2012 to February 2014, under the montanera regimen, and with a total of 995 animals observed (498 males and 497 females). The data were analyzed with SAS by means of general models and proc mixed. Mean group size along the year was of 17 ± 12.9 individuals, but this was significantly lower (P < 0.05) during the montanera (12 ± 0.8) and at midday (13 ± 0.8). Groups were bigger (P < 0.05) when they were more than 50 m from a tree (23 ± 1.8), or <10 m from the shelter (25 ± 1.5), the feeding area (31 ± 3.1) and the water-bath area (25 ± 1.5). Nine percent of the groups were solitary animals, being higher (P = 0.0286) during the montanera (11%) than the rest of the year (8%) and being formed in 68% by males. Males were less involved in mixed groups than were females (75% vs. 91%), especially in spring, where the largest (P < 0.0001) male groups were found. Female groups were less frequent and smaller (P < 0.0001) than were male and mixed groups. In conclusion, although males were castrated at a very young age, they showed a different behavior than females, forming in bachelor groups during the spring and being less involved in mixed groups and with more solitary animals. During the montanera, when animals were feeding on acorns and other natural resources, groups were smaller and closer to the trees, solitary males reaching a maximum percent.

“…From a practical, technical perspective, the animal welfare concept has evolved from an initial, almost exclusive consideration of the animal, towards a multidimensional concept, which at present has strong, obvious socio-economic implications. It has been, therefore, claimed that overall welfare assessment should involve not only animal welfare science, but also economic and social science aspects [ 2 ], as well as moral and ethical considerations [ 3 , 4 ].…”

Simple SummaryWe studied different EU production standards and initiatives to determine whether there is still room or not for further animal welfare improvement, and which should be the best way to achieve it. Many of the adopted measures in these standards and initiatives are scientifically supported, but other aspects that are equally important for animal welfare are not included in any of them. Animal welfare improvement should consider, for each country, those aspects actually benefiting animals, but also the social expectations within each country. Economic constraints might explain the gap between what society demands, and what farm animals actually need.AbstractInformation about animal welfare standards and initiatives from eight European countries was collected, grouped, and compared to EU welfare standards to detect those aspects beyond minimum welfare levels demanded by EU welfare legislation. Literature was reviewed to determine the scientific relevance of standards and initiatives, and those aspects going beyond minimum EU standards. Standards and initiatives were assessed to determine their strengths and weaknesses regarding animal welfare. Attitudes of stakeholders in the improvement of animal welfare were determined through a Policy Delphi exercise. Social perception of animal welfare, economic implications of upraising welfare levels, and differences between countries were considered. Literature review revealed that on-farm space allowance, climate control, and environmental enrichment are relevant for all animal categories. Experts’ assessment revealed that on-farm prevention of thermal stress, air quality, and races and passageways’ design were not sufficiently included. Stakeholders considered that housing conditions are particularly relevant regarding animal welfare, and that animal-based and farm-level indicators are fundamental to monitor the progress of animal welfare. The most notable differences between what society offers and what farm animals are likely to need are related to transportation and space availability, with economic constraints being the most plausible explanation.
