Summary: The study found that purine bases have a significant impact on the sensory quality of pork, with total purine and two major uricogenic bases negatively correlated with tenderness, juiciness, oiliness, and overall liking, while guanine content was positively correlated with umami. These results suggest that different purine bases with various uricogenic effects influence different sensory quality indices of pork.

Summary: The quality of pork products depends on the properties of the raw material and processing conditions. Factors such as pig husbandry practices and processing techniques influence the quality of processed pork products. Cooked ham and dry-cured ham are two important processed pork products that are affected by various factors in both animal production and processing steps. The variability of raw material poses challenges for achieving uniformity and homogeneity in processed pork products. The properties of raw material and processing conditions interact to determine the quality attributes of cooked ham and dry-cured ham. The quality of the products is built along the entire chain from farm to fork.

Summary: The study analyzed the feasibility of using supercritical CO2 (SC-CO2) and conventional vacuum steam distillation (VSD) for deodorization and defatting of dried pork liver. Both techniques were effective in reducing volatile organic compounds (VOCs), with SC-CO2 achieving a higher reduction rate of 81.3% UA compared to VSD's reduction rate of 67.6% UA. SC-CO2 also completely eliminated three characteristic compounds of raw pork liver, potentially reducing unpleasant flavors. Furthermore, SC-CO2 led to a reduction in fat content by 24.9%.

Summary: The study examined the impact of high inclusion of co-products in pig diets during the finishing stage on pig growth performance, meat quality, and boar taint compounds. Pigs fed the alternative diet showed lower feed intake, but growth rate and feed conversion efficiency were unaffected. Pork from pigs fed the alternative diet had lower a* and Chroma values and protein content, but other meat quality characteristics were unaffected. The alternative diet also reduced backfat skatole levels. This finding suggests that high inclusion of co-products in pig diets can be beneficial for pig production.

Summary: Feeding high-fiber coproducts to grow-finish pigs can compromise their growth performance, while the inclusion of antibiotic growth promoters may improve it. The metabolic interactions between fiber and antibiotics in the digestive tract of pigs and their detectability in feces have not been well-examined. In this study, metabolomic analysis showed comprehensive metabolic changes in pigs fed with high-fiber coproducts, while selective metabolic changes were observed with the inclusion of antibiotics. Limited metabolic interactions were found between fiber and antibiotics treatment. Fecal metabolome can be used as a source of biomarkers to monitor and predict the metabolic performance of grow-finish pigs.

Summary: This study aimed to determine and compare the environmental impacts of five diet formulation strategies and feeding programs for growing-finishing pigs in the U.S. The addition of food waste (FW) to diets resulted in the least overall greenhouse gas emissions, water consumption, and land use compared with other feeding programs, while the Midwest region had the least contributions to GHG emissions and land use attributed to feed and manure. Water consumption associated with feeding programs was highest in the Southwest region.

Summary: Zinc is a required nutrient for pigs but is commonly supplemented at concentrations that greatly exceed estimated requirements. Feeding pharmacological concentrations of Zn from ZnO to pigs for 1 to 2 weeks post-weaning reduces post-weaning diarrhea and improves growth performance. Feeding elevated dietary levels of Zn to sows during the last 30 days of gestation can reduce the incidence of low-birth-weight pigs and pre-weaning mortality. Most of the dietary Zn consumed by pigs is not retained in the body and is subsequently excreted in manure, which led several countries to impose regulations restricting dietary Zn concentrations to reduce environmental impacts. Although restricting Zn supplementation in swine diets is a reasonable approach for reducing environmental pollution, it does not allow capturing health and productivity benefits from strategic use of elevated dietary Zn concentrations. Therefore, we propose feeding strategies that allow strategic use of high dietary concentrations of Zn while also reducing Zn excretion in manure compared with current feeding practices.

Summary: Feeding pigs oxidized lipids has negative effects on growth and health, but the impact on amino acid metabolism has not been well studied. This research found that feeding oxidized corn oil to nursery pigs caused changes in amino acid homeostasis and metabolic pathways. These changes, including increased antioxidant responses, suggest that pigs are capable of adapting to the consumption of oxidized lipids by adjusting amino acid metabolism.

Summary: Traditionally, swine diets focused on meeting nutrient requirements at the lowest cost, without considering the environmental impact. This study aimed to compare the effects of four different grower-finisher feeding programs on growth performance, carcass composition, nitrogen utilization efficiency, and environmental impacts. The results showed that feeding diets containing corn and soybean meal (CSBM) led to better growth performance, carcass composition, and reduced environmental impacts compared to diets with lower protein content or distillers dried grains with solubles (DDGS) supplementation.

Summary: Global trade of feed ingredients contaminated with swine viruses raises concerns about disease transmission. Biosecurity protocols and measures are needed to prevent virus contamination, along with the development of accurate analytical methods for detecting viable virus concentrations. Effective decontamination strategies and the use of antiviral ingredients are also important. Current lack of standardized procedures and systems for measuring virus contamination in feed supply chains contributes to high uncertainty.
