Developing livestock and equine trainings to empower county Extension agents is challenging, especially when spanning in-person and online delivery modules. Real life application of training concepts is difficult, particularly when participants have varied backgrounds and experience. Thus, we assessed if scenario-based training modules were an effective training method across in-person and virtual formats. The same scenario-based training was delivered at three, regional in-person trainings (n = 42), and one virtual training (n = 32). Training format consisted of four, species-specific lectures addressing various production topics. Small groups then developed recommendations for a specific scenario, followed by a debriefing session consisting of group reactions and specialist recommendations. Topic-area application to county programs, instructor effectiveness, and overall benefit of the training session were evaluated (Qualtrics, in-person n = 26, 62% completion; virtual n = 17, 53% completion). Data were assessed using analysis of variance and mean comparisons (α=0.05), with Tukey’s pairwise post hoc analysis where appropriate (STATA 16). Across all sessions, likert scale responses (1=poor and 5=excellent, n = 43) indicated lecture sessions were applicable to county areas of need across material content (mean±SD, cattle=4.71±0.57, equine=4.64±0.50), teaching effectiveness (cattle=4.77±0.42, equine=4.75±0.43), and overall quality (cattle=4.68±0.57, equine=4.67±0.51), respectively. Scenario-based training benefit was not influenced by the number of times an agent had attended in-service training on livestock species, agent appointment (youth vs. adult educator), or training location (p >0.05). Attendance at previous in-service trainings (cattle P = 0.005; equine P = 0.013) and agent appointment (cattle P = 0.0006; equine P = 0.05) had a significant impact on the number of questions agents reported to have received on scenario topics in the last 12 months. More topic area questions were reported by agents with adult education responsibilities and previous training attendance. Based upon these results, scenario-based training is an effective in-person and virtual training tool for 4-H and adult Extension agents of varying experience.

Classification of horses as livestock or companion animals is often contested in cases of management and welfare concerns, legislation, and educational forums. Limited data are available regarding perception of equids in relationship to animal agriculture management practices. Therefore, our objective was to test associations between livestock management practices and perception of horses as companion animals or livestock. An online survey was administered for 6 weeks to U.S. residents over age 18. Participants provided demographic information, connection to the industry, and welfare definition of choice. Management questions included 2 scenarios each—one regarding horses and a direct comparison for another livestock species. Respondents then chose which scenario was most concerning or if the scenarios were equally non-concerning (i.e. no issue) or concerning. Analyses were performed using SAS (SAS Institute, Cary, NC), with significance set at α=0.05. Multinomial logistic regression (PROC GLIMMIX) was used to test factors affecting management scenario responses. Out of 1,334 respondents, 807 (60.5%) categorized equids as companion animals; 527 (39.5%) classified equids as livestock. Welfare definition, equid classification, and industry connection significantly affected responses to every management scenario (P < 0.01). People who classified horses as livestock had 2.8 times greater odds (OR=2.8; 95%CI:1.8, 4.5) to select lack of shelter during spring months as equally non-concerning for horses and cattle rather than selecting horses without shelter as a concern compared to respondents who classified horses as companion animals. Respondents heavily connected to the equine industry were less likely (OR=0.38; 95%CI:0.19, 0.75) to select that both species without shelter were concerning rather than selecting that only horses lacking shelter was concerning compared to respondents lightly connected to the industry. Understanding associations between public perceptions of livestock management and individual’s welfare definition, equine classification and industry connection may improve our ability to educate the public regarding animal agricultural practices.

Effects of pig birth (first 3-wk period) and rearing environments on growth and muscle quality characteristics of loins were evaluated in three experiments over seasons in west Texas and central Missouri. Housing systems included indoor slatted-floor buildings, indoor deep-bedded buildings, outdoor housing on dirt, and outdoor housing on alfalfa pasture. Experiments were conducted during the growing/finishing phases and pigs were slaughtered at the same age. Loins were collected, vacuum-packaged, and stored for 14 d at 2 degrees C. Pigs born and finished in an outdoor environment during the summer months (Exp. 1) had a greater ADG (0.92 vs 0.82+/-0.06 kg/d, P < 0.05) and had heavier carcass weights (87.9 vs 78.4+/-2.4 kg, P < 0.05) than pigs born and finished in an indoor environment with a slatted-floor finishing building. Carcasses from the outdoor-reared group measured a larger (P < 0.05) loineye area and were fatter (P < 0.01) at the first rib, last rib, and last lumbar vertebra measurements than carcasses from the indoor-reared group. Loin chops from outdoor-reared pigs had darker color scores in the retail display case throughout the 4-d period, measured lower L* values on d 1, and had more discoloration and browning on d 4 than loin chops from the indoor-reared group. During the winter months (Exp. 2), no difference was detected in ADG, carcass measurements, sensory characteristics, or shear force values from indoor-born pigs placed in either an outdoor or indoor finishing environment. Pigs finished on deep bedding (Exp. 3) had heavier carcass weights and more backfat (P < 0.01) than pigs finished on slats, but no differences were detected in sensory panel or shear force results. Overall, carcass measurements, pH, drip loss, sensory panel, and shear force values were similar among the groups finished in different housing systems. Outdoor or deep-bedded systems may increase growth rates of pigs if suitable land area and resources are available, but pork quality of loins will be similar for pigs finished in either conventional or alternative systems.

The meaning of the term "stress" as it applies to animal husbandry is discussed. Because "stress" is used with various meanings, its application is often misinterpreted. Stress in general is looked upon as a symptom resulting from exposure of an animal to a hostile environment. To some it is a nonspecific response to all environmental forces; others feel there are specific stress symptoms caused by specific environmental forces. The term stress is sometimes used to describe the hostile environment. The correct usage depends upon the school of thought espoused. A common working definition of physiologists is that "stress" consists of external body forces that tend to displace homeostasis and "strain" is the internal displacement brought about by stress. There are environmental forces continuously acting upon animals that disrupt homeostasis, resulting in new adaptations that can be either detrimental or advantageous to man's interest. Measuring the magnitude of stress often means measuring the degree of adaptation. The important function of livestock management is to avoid the detrimental adaptations and capitalize on the advantageous ones.
