Special Issue Information

Dear Colleagues,

For decades, the meat industry has benefited from advances in animal genetics, nutrition, housing, management strategies, etc., in efforts to maximize WHC (selling water at the price of meat) and color. The focus of scientific literature has followed the same line. This special issue will proceed from an animal welfare point of view in which any treatment that improves animal welfare and enhances both carcass characteristics and meat quality is welcome.

During the last 20 years, meat’s visual appearance has been the most important sensory property related to consumer purchasing decisions. Consumers strongly associate a bright red color with freshness and superior meat quality.

Nevertheless, in the last 4–5 years, the consumer has been progressively educated in concepts such as welfare, good practices in animal production, water holding capacity and color, thus increasing customer requirements and demands when choosing to purchase a meat product.

The phrase “welfare-enhanced meat” can involve specific issues such as neonatal interventions in farms or protocols to avoid heat stress in fattening animals or sows, as well as more general aspects such as sustainability in meat production considering intensive production (efficiency, productivity and food security).

In addition, the first thing that comes to mind when considering “welfare-enhanced meat” is the improvement in transport and production systems of common species such as pork, beef, poultry, etc., and the implication for consumer demands and product quality. However, the point of view of game meat and/or wild species should be also considered. In this case, the means of dealing with consumer requirement differ and there are other quality parameters that require study.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Heat stress is a significant environmental problem that has a detrimental impact on animal welfare and production efficiency in swine farms. The current study was conducted to assess the effect of low-intensity showers, provided during critical high-temperature hours daily, on body external temperature, feeding pattern, and carcass and meat quality characteristics in fattening pigs. A total of 400 animals (200 barrows and 200 gilts) were randomly allotted in 40 pens. A shower nozzle was installed over 20 pens (half barrows and half gilts) where pigs received a low-intensity shower for 2 min in 30 min intervals from 12 to 19 h (SHO group). Another group without showers was also considered (CON). Feeder occupancy measurement, thermographic measures, and carcass and meat quality parameters were studied. In the periods with higher environmental temperatures, SHO animals showed an increase in the feeder occupancy rate compared to the CON group. A decrease in temperature was observed after the shower, regardless of the anatomical location (p < 0.005). The treatment with showers led to higher values than in the CON group of 4.72%, 3.87%, 11.8%, and 15.1% for hot carcass weight, lean meat yield, and fat thickness in Longissimus Dorsi (LD) and Gluteus Medius muscles, respectively (p < 0.01). Pork from CON showed a 14.9% higher value of drip loss, and 18.9% higher malondialdehyde concentration than SHO (p < 0.01); meanwhile, intramuscular fat content was 22.8% higher in SHO than in CON (p < 0.01). On the other hand, the CON group exhibited higher L* (2.13%) and lower a* and b* values (15.8% and 8.97%) compared to the SHO group. However, the pH20h of the CON group was significantly lower than that of the SHO group (p < 0.001), indicating a softer pH decrease. Related to fatty acids in subcutaneous outer and inner layers and intramuscular fat, the CON group showed higher ΣSFA and lower ΣMUFA and Δ9-desaturase indexes than SHO (p < 0.05). In conclusion, the amelioration of heat stress through showers at critical times should be considered an interesting tool that improves both carcass and meat quality, as well as animal welfare.
