“…Indeed, lipid synthesis mainly occurs in adipose tissues of pigs. Subcutaneous and visceral adipose tissues with different anatomical locations show specific development and deposition, especially in de novo synthesized fatty acids due to desaturation and elongation [43,44]. NCG is involved in regulating the metabolism of energy substrates through nitric oxide production [19,45].…”

The present study evaluated the effects of dietary N-carbamylglutamate (NCG) on carcass traits, meat quality, and fatty acid profiles in the longissimus dorsi muscle and adipose tissues of Chinese Ningxiang pigs. A total of 36 castrated female pigs with a similar initial weight (43.21 ± 0.57 kg) were randomly assigned to two treatments (with six pens per treatment and three pigs per pen) and fed either a basal diet or a basal diet supplemented with 0.08% NCG for 56 days. Results showed that dietary NCG reduced shear force (p = 0.004) and increased drip loss (p = 0.044) in longissimus dorsi muscle of Ningxiang pigs. Moreover, increased levels of oleic acid (C18:1n9c) (p = 0.009), paullinic acid (C20:1) (p = 0.004), and α-linolenic acid (C18:3n3) (p < 0.001), while significant reduction in the proportions of arachidonic acid (C20:4n6) (p < 0.001) and polyunsaturated fatty acid (PUFA) (p = 0.017) were observed in the longissimus dorsi muscle of pigs fed NCG when compared with those fed the control diet. As for adipose tissues, the C20:1 (p = 0.045) proportion in dorsal subcutaneous adipose (DSA), as well as the stearic acid (C18:0) (p = 0.018) level in perirenal adipose (PA) were decreased when pigs were fed the NCG diet compared with those of the control diet. In contrast, the margaric acid (C17:0) (p = 0.043) proportion in PA were increased. Moreover, the NCG diet produced PA with a greater proportion of total PUFAs (p = 0.001) (particularly linoleic acid (C18:2n6c) (p = 0.001)) compared with those produced by the control diet. These findings suggest that dietary NCG has beneficial effects by decreasing the shear force and improving the healthfulness of fatty acid profiles, providing a novel strategy for enhancing meat quality of pigs.

“…En la carne, el contenido de ácidos grasos saturados y monoinsaturados fue mayor, y el de poliinsaturados menor que en la grasa de cobertura (P ≤ 0,05). Esto se podría deber al consumo de forrajes verdes desde los inicios de su desarrollo, ya que la grasa subcutánea presenta una tasa de renovación más lenta que la grasa intramuscular (Jiang et al, 2018). En este estudio los animales estuvieron estabulados sin acceso a pradera el último mes, lo cual podría haber influido en la composición final de la grasa infiltrada en la carne.…”

“…En este estudio los animales estuvieron estabulados sin acceso a pradera el último mes, lo cual podría haber influido en la composición final de la grasa infiltrada en la carne. Por lo tanto, para aumentar los ácidos grasos monoinsaturados y poliinsaturados en la carne de cerdos de sistema natural, sería recomendable prolongar el pastoreo hasta el final del proceso productivo (Jiang et al, 2018). Álvarez-Rodríguez et al (2016) determinaron un mayor contenido de ácidos grasos poliinsaturados en carne de cerdos de sistema orgánico, pero sin acceso a praderas, comparado con cerdos de sistema convencional, lo que se atribuye a ácidos grasos contenidos en la soya, como el α-linolénico (18:3n3).…”

Swine production in Chile is mainly based on an intensive confinement production system (conventional system). However, in recent years, increasing interest for healthy food has resulted in the use of a natural production system, which is an attractive alternative consisting of an extensive system with access to grassland. The aim of this study was to determine the composition of pork meat produced in a natural system. The pH and proximal analysis of: pork loin (Longissimus dorsi) (n = 54) and pork leg pulp (n = 54) were determined. The profile of fatty acids in loin, leg pulp and

“…Ningxiang pigs are well-known for their excellent meat quality and have become one of the four best-known local breeds in China. It has been reported that unsaturated fatty acids (UFAs) in Ningxiang pork account for up to 59.6% of all fatty acids [2].Moreover, He etal. [3] found that the serum of Ningxiang pigs contains more unsaturated lipids than that of lean pigs under the same environment and feeding conditions.…”

Background In recent years, thousands of different circular RNAs (circRNAs) have been identified through comparative analysis of different pig breeds. However, very few studies have investigated the spatiotemporal expression patterns of circRNA during organ development, which is crucial for functional and evolutionary analysis. Results In this study, we systematically analyzed circRNAs associated with fatty acid metabolism in the three main organs (muscle, fat and liver) a tfour growth time points (30 d, 90 d, 150 d and 210 d after birth) for Ningxiang pigs, awell-known native pig breed in China known for its excellent meat quality. We identified 61,683 circRNAs and analyzed their molecular characteristics, potential functions, and interactions with miRNAs. The circRNAs exhibited notable spatiotemporal specificity in the form of dynamic expression. At 90 d, the number and complexity of differentially expressed circRNAs in the liver was the highest.We used STEM (Short Time-series Expression Miner) to perform time series analysis on differentially expressed circRNAs and observed that there were multiple model spectra that were significantly enriched with time changes in all three organs. All the significantly changed circRNAs, miRNAs and mRNAs obtained from STEM analysis of each tissue were utilized to confirm that the circRNA and mRNA have a targeting relationship with miRNA. Notably, we screened 2384 (fat), 2672 (muscle) and 9187 (liver) circRNA-miRNA-mRNA network pairs related to developmental time changes. Finally, we used fluorescence in situ hybridization (FISH) to demonstrate the dynamic subcellular localization of circRNA during development. Conclusion These data suggest that circRNA is highly abundant in muscle, fat and liver and is dynamically expressed in a spatiotemporal manner. These results suggest that circRNAs play important roles in fat metabolism in Ningxiang pigs. Our findings also provide new ideas and perspectives for the study of Ningxiang pigs' lipid metabolism regulation pathway and meat quality traits.
