Special Issue Information

Dear Colleagues,

Meat quality includes numerous traits that can be affected by intrinsic and extrinsic factors. Meat quality can be analysed in terms of the nutritional properties they provide for human consumption, the traits that determine they safety of the meat (hygiene and toxicology), the traits that are important for meat processing, and the set of traits that determine sensory quality. Thus, the analysis of meat quality can be approached from different points. The genetic background of a species and/or breed has an inevitable effect on farm animal meat quality and its interaction with production systems, mainly with respect to nutritional properties and pre-mortem handling results regarding the specific physio-chemical characteristics of the meat. During post-mortem handling, transport and shelf-life microorganism contamination can occur, leading to meat spoilage and unappetizing or even poisonous or infectious effects. The meat industry requires specific meat characteristics, and different post-mortem handling and treatment methods can be beneficial to improve meat quality parameters. In addition to nutritional traits, consumers are becoming more interested in the sensory characteristics of meat (juiciness, flavour, and texture), which determine meat eating quality, as well as the welfare of the animals used for meat production. Due to these broad topics, new studies are valuable sources of information on the diverse effects on meat quality parameters.

This Special Issue focuses on the current research on improving farm animal meat quality and the relevant strategies used to achieve this goal. We welcome the submission of studies that present new and valuable results regarding the effects of breeding and genetics on meat quality and the effects of production systems and nutritional strategies, welfare status, and pre- and post-mortem handling procedures on the nutritional, physio-chemical, and sensory profiling of farm animal meat quality. Both original research articles and reviews are welcome.

Abstract

In the livestock industry, an excessive accumulation of subcutaneous fat diminishes the proportion of lean meat, while elevated intramuscular fat (IMF) content is associated with enhanced meat quality. However, the heterogeneity of various fat depots in pigs remains incompletely understood. Comprehensive tissue section, lipidomic, and transcriptomic analyses indicated that the maturity of IMF was significantly less than that of both intermuscular and subcutaneous fats. We identified 467 lipids across 29 lipid classes in total, revealing that IMF exhibits unique lipid composition and transcriptional profiles. More importantly, several lipids, including GalCer, S1P, CL, AcCa, PC-O, PE-O, and sulfatide, are highly enriched in intramuscular fat and may play pivotal roles in neuromodulation, mitochondrial function, lipogenesis, and membrane signaling. In conclusion, we unveiled unique lipid composition and molecular regulatory pathways of porcine IMF, offering new insights for the synergistic breeding that aims at optimizing pig backfat thickness and IMF content.
