  Abstract The present study used 48 lambs originating from three different locations in the Western United States (16 lambs per location; 8 ewes and 8 wethers per location). Each consisting of similar breed composition (Suffolk cross) that were selected to represent weight by age at harvest treatments: light weight carcasses at 5 mo (LW5, 31.81 ± 1.88 kg), light weight carcasses at 12 mo (LW12, 35.09 ± 4.45 kg), heavy weight carcasses at 12 mo (HW12, 57.89 ± 4.70 kg) with different carcass weight compositions. Older heavy weight lambs (HW12) had greater (P ≤ 0.01) hot carcass weight, ribeye area, backfat and body wall thickness, and yield grade compared with light weight lamb carcasses (LW5 and LW12). The longissimus thoracis longissimus thoracis (LT) from older lamb carcasses (LW12 and HW12) had a greater (P ≤ 0.01) total lipid percentage compared with younger lamb carcasses (LW5). Across harvest weight and age treatments, wether carcasses had greater (P ≤ 0.05) total lipid percentage compared with ewe carcasses. Slice shear force values were greater (P ≤ 0.01) for both the LT and semimembranosus from older lambs (LW12 and HW12) compared with LW5 lambs, with no differences between ewes and wethers. Lamb flavor intensity was greater (P ≤ 0.05) for the LT of LW12 lambs and tended (P = 0.08) to be greater for HW12 lambs, compared with the LT from LW5 lambs. The off-flavor intensity of the LT was greater (P ≤ 0.01) for older lambs (LW12 and HW12) compared with LW5 lambs. Interestingly, the lamb flavor and off-flavor intensity scores of the ground shoulder exhibited a treatment × sex interaction. Lamb flavor intensity of LW12 lamb was greater (P ≤ 0.05) from ewes compared with wethers, whereas wethers had a greater (P ≤ 0.05) lamb flavor intensity compared with ewes for HW12 lambs, and LW12 ewe lambs had a greater (P ≤ 0.05) off-flavor intensity compared with all other treatment × sex treatment combinations. Overall, lambs in the present study possessed a mild lamb flavor, typically with greater lamb flavor and off-flavor intensities for older animals; while slice shear force and LT lipid percentage increased as animal age increased at the time of harvest.

  The objective was to assess the consumer (n = 360) palatability and satisfaction of enhanced (7%) and nonenhanced Australian grain-fed, Australian grass-fed, and US grain-fed beef from 2 beef muscles. Strip loin (longissimus lumborum [LL]) and top sirloin butt (gluteus medius [GM]) subprimals were collected from 12 Australian grass-fed, 12 Australian grain-fed, and 12 US grain-fed (USDA Choice) carcasses. In addition, tenderloin (psoas major) and eye of round (semitendinosus) subprimals were collected from the same US carcasses to serve as anchors for high and low palatability. All subprimals were aged until 29 to 32 d postmortem. All fabrication and enhancement occurred in Lubbock, Texas. Data were analyzed initially as a randomized complete design and subsequently as a split-split plot design, with the main effects of country of origin/diet (Australian grain-fed, Australian grass-fed, and US grain-fed), muscle (LL and GM), and enhancement (0% or 7%) and all potential interactions as fixed effects. Enhancement significantly improved palatability in both LL and GM steaks as evidenced by greater (P < 0.05) consumer ratings for tenderness, juiciness, flavor liking, overall liking, and satisfaction. Enhancing LL steaks resulted in consumer responses that were comparable or superior to consumer responses for psoas major samples. Similarly, enhancing GM steaks resulted in consumer responses that were comparable or superior to nonenhanced LL samples. Consumers reacted least favorably to nonenhanced Australian grass-fed beef as they rated all palatability traits lowest (P < 0.05) for both LL and GM samples. However, enhancing grassfed beef resulted in consumer responses that were similar (P > 0.05) to nonenhanced grain-fed beef. This response to enhancement was observed in consumer scores for both LL and GM samples. Consumers could not detect differences (P > 0.05) in tenderness, juiciness, flavor, overall liking, or satisfaction between grain-fed beef from Australia and the US.

• Lean on Your Land Grant: One University’s Approach to Address the Food Supply Chain Workforce during the COVID-19 Pandemic

  During the spring 2020 COVID-19 outbreak, faculty and staff within Ohio State University's College of Food, Agricultural and Environmental Sciences came together from multiple disciplines to support essential agricultural workers. Concerted leadership from administration provided a framework for this interaction to occur while faculty worked off-campus to address the many issues identified by the agricultural community, the industry sector, and other state agencies. During the onset period, much of our work was reactive; our efforts to address worker safety and health involved three primary areas within: 1) production agricultural workers, 2) produce growers and direct marketing enterprises, and 3) meat supply chain workers. Communication to target audiences relied upon our ability to convert face-to-face programming into virtual webinars, social media, and digital publications. A Food System Task Force mobilized specialists to address emerging issues, with one specific topic related to Personal Protective Equipment (PPE). As we continue to face new seasons in agriculture production, and pockets of COVID-19 outbreaks within our state, we will continue to address the dynamic needs of our food supply systems. There are implications for how we will teach the agricultural workforce within a virtual platform, including the evaluation of the effectiveness of those training programs. There are renewed opportunities to integrate health and safety content into other Extension teams who conventionally focused on production practices and farm management topics. Several research themes emerged during subgroup dialog to pursue new knowledge in workers' cultural attitude and barriers, PPE design, PPE access, and overall attitude toward COVID-19 health practices.
