“…In general, pigs fed pastures have a lower performance, due to greater development and weight of gastrointestinal tract [22]. For other hand, local breeds have a high dorsal fat thickness (29-63mm) although this feature can be modified through the feed and the production system [1,32]. Pasture intake with a restricted concentrated diet improved the ratio of concentrated intake: LW gain.…”

Trace elements, macro minerals and iron forms content, in meat of Pampa Rocha pig reared indoor and outdoor with pasture

Pampa Rocha pig (PRp) is a local breed present and produced in Uruguay. Twenty-three pigs were used housed indoor (I) and outdoor with pasture (O), live weight 94.5 and 91.5 kilograms (kg), respectively. Animals were fed with concentrate in both systems, but pasture access was granted to the animals in the O. After slaughtering, the Longissimus dorsi (LD), Psoas major (PM), Gluteus medius (GM), Semitendinosus (ST), Biceps femoral (BF), and Quadriceps femoris (QF) were sampled to be analyzed. In O, the growth of pigs was lower, and improved the concentrate intake:live weight gain. The content of heme iron and the ratio Fe Heme/Fe Total were higher in outdoor. The LD muscle showed lower total and heme iron content. For ham, QF showed the highest values of heme iron. No differences were observed between systems or muscles in the content of Ca, Mg, and K. The Na content was similar in both systems, and higher in PM. No differences were observed between production systems for trace elements content. According to the results obtained, it is possible to produce PRp meat with interesting mineral content, in two alternative systems to the classic confinement. This breed produces healthier meat in O. It could be interesting to exploit some differences founded between LD and PM muscles, which are normally consumed as fresh meat, and are adapted to the different demands of human nutrition. Rearing in O that include pastures is a good way to promote and add nutritional value to this local breed.

“…menores que los de las razas seleccionadas. De hecho, en un estudio reciente realizado en cerdos concluyen que los rendimientos obtenidos en razas autóctonas y tradicionales no son comparables con los de las razas comerciales, precisamente no solo por el rendimiento como tal (que es muy inferior), sino también debido al alto grado de engrasamiento de estos animales (Araujo et al, 2018). Sin embargo, los productos derivados de la ganadería extensiva con razas autóctonas presentan características superiores a los productos de animales procedentes de razas mejoradas y criados en extensivo.…”

Las modificaciones derivadas del cambio climático hacen que sea necesario establecer estrategias de mitigación y adaptación del sector de la ganadería. La ganadería extensiva es un sector que se adapta de modo continuo y dinámico a los cambios y condicionantes que se presentan, por lo que es una herramienta muy importante como parte de la solución del cambio climático. Su resiliencia pasa por un aprovechamiento eficiente de los recursos y una programación adecuada de su uso que garantiza la gestión sostenible de los pastos, los animales y las explotaciones para mitigar el cambio climático, reduciendo al mínimo la generación de residuos y permitiendo una sinergia agrícola-ganadera. La gestión de los sistemas pastorales tendrá un papel fundamental a la hora de minimizar el impacto climático sobre la ganadería al contribuir a conservar la biodiversidad. Además, los sistemas de predicción son esenciales para el desarrollo de estrategias de adaptación, adelantándose a la toma de decisiones y evitando en la medida de lo posible los efectos adversos provocados por el cambio climático.

The aim of the current experiment was to characterize and evaluate the effect of the dry-curing process on chemical composition, physicochemical properties, and sensory characteristics of the dry-cured Bísaro shoulders. For this purpose, thirty-eight raw forelegs were used, and no nitrites were added during the dry-curing process. This process increased protein, fat, ash content, and pH, with a decrease in moisture and water activity (p < 0.001). The dry-cured shoulders were darker (L*), less red (a*), and less yellow (b*) than the raw shoulders (p < 0.001), and this may be mainly due to the moisture reduction. The proportion of polyunsaturated fatty acids (PUFA) decreased during processing, whereas the saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) increased (p < 0.001), which could be related with the oxidative degradation. The sensory analysis showed that dry-cured Bísaro shoulders presented similar organoleptic characteristics to other dry-cured meat products. Also, the chemical composition and fatty acid profile of the dry-cured Bísaro shoulder showed results comparable to those of other cured products. This study revealed that it is possible to obtain safer and healthier dry-cured Bísaro shoulder products judging by these characteristics, since nitrites were not added in its preparation. These findings, along with the product’s high sensory attributes similar to more popular products such as ham, would give more advantage for its acceptability and market demand.
