DIETARY STARCH DILUTION STRATEGIES TO IMPROVE RUMEN HEALTH AND PERFORMANCE IN FEEDLOT CATTLE
Get PDFABSTRACT
The objectives of this study were to evaluate the effects of starch dilution with
different sources of dietary fiber from terminal implant to slaughter on feedlot cattle
performance, carcass characteristics, and rumen buffering characteristics. Steers (n = 416;
372 ± 2.67 kg) were allocated to 48 pens in a randomized complete block design. Pens of
cattle (n = 12 per treatment) were assigned to 1 of 4 treatments consisting of steam-flaked
corn-based diets containing: 1) CON; 7.50 % corn stalks on a DM basis fed for the entire
feeding period, 2) CS; 14.75% corn stalks on a DM basis fed from terminal implant to
slaughter, 3) WD; 9.50% wet distillers grains with solubles, and 7.50% corn stalks on a
DM basis fed from terminal implant to slaughter, and 4) NR; 19.00% wet distillers grains
with solubles, and 0.0% corn stalks on a DM basis fed from terminal implant to slaughter.
Six days before administration of the terminal implant, steers were transitioned to their
treatment diets using a two-ration system, whereas CON consumed the same diet
throughout the entire feeding period. Within each pen, 2 steers were randomly selected to
receive an indwelling ruminal pH bolus to quantify rumen pH and a 3-axis accelerometer
tag to assess rumination time. Diet samples were collected weekly to determine particle
size, NDF concentration, and physically effective fiber (peNDF). At slaughter, rumens
were evaluated for the presence of scarring and lesions. Performance (BW, DMI, ADG,
G:F) was not different (P ≥ 0.34) from initial to transition. Dry matter intake and
metabolizable energy intake from transition to final were greatest for cattle consuming
CS, intermediate for WD and CON, and least for NR (P < 0.01). Final BW and ADG did
iv
not differ among treatments from transition to final (P ≥ 0.19); however, G:F was greatest
for NR, intermediate for WD, and least for CS and CON (P = 0.10). There was no
difference (P ≥ 0.24) in hot carcass weight, dressing percentage, marbling score, quality
grade, yield grade, and percentage KPH fat among treatments. Steers consuming CS had
greater (P = 0.08) 12th rib fat thickness. The proportion of abscessed livers did not differ
(P = 0.26) among treatments. The peNDF was greatest for CS, intermediate for WD and
CON, and least for NR (P < 0.01). Particles > 4.0 mm were greatest for CON and CS,
intermediate for WD, and least for NR (P < 0.01). A treatment × day interaction (P <
0.01) was observed for daily rumination minutes and rumination per kg of DMI;
rumination was greater for CS, intermediate for WD and CON, and least for NR early in
the finishing period and greater for CS than NR towards the end of the finishing period.
Similarly, a treatment × hour effect (P < 0.01) was observed for hourly rumination; cattle
consuming CS had greater rumination than NR at 0200, 0400, 0600, 1200, 1400, 2000,
2200 and 2400 h. There was also a treatment × day interaction (P < 0.01) for rumen pH,
but the diet appeared to have minimal effects on pH throughout the entire feeding period.
A treatment × hour effect (P < 0.01) was observed for hourly pH; cattle consuming CON
had greater rumen pH than WD and NR at 0400, 0600, and 800 h, but had minimal
effects throughout the remainder of the 24 h period. Rumen scores of cattle consuming
CON had a greater (P = 0.09) percentage of rumen score 3, but there were no other
differences among dietary treatments (P > 0.31)The results of this study indicate that
increasing the proportion of corn stalks in the diet post-terminal implant administration
increases DMI, dietary peNDF, and rumination time. However, ruminal pH was
v
minimally impacted by decreased starch and greater fiber provided from either corn
stalks or WDGS and suggests that roughage can be replaced with fibrous corn milling
byproducts without negatively impacting rumen health
Silent Reflections: A Clown Noir Cabaret
No full textWe started discussing the project as early as March of 2022. Then we met as a team over zoom every Sunday, starting in July, to prepare for the residency that began Aug 13th. The 3 founding members of WFM Theatre arrived in Canyon on Aug 13th and had their first in-person meeting on Aug 13th. Then on Aug 14th we began a week of development and rehearsals that involved the student designers as collaborators. We made a commitment to stop creating new work and to have the show finalized by Saturday Aug 20th, so that the designers would have time to finish their lighting, sound and graphic design work in time for the show on Aug 26th.The objectives of this project were to bring The Women From Mars Theatre Company to WT for a 2-week residency. During this residency they would work with 4 student employees/designers to research, develop and create new technical and performative aspects, including three new scenes for the show, "Silent Reflections," culminating in a premiere performance. They would also teach a 5-hour clowning workshop, presented a panel discussion with Gender Studies and have a talk back after the performance

THE EFFECT OF A DIRECT FED MICROBIAL (10-G) ON LIVE ANIMAL PERFORMANCE, CARCASS CHARACTERISTICS, SALMONELLA PREVALENCE OF FED BEEF HEIFERS
No full textSalmonella is a major cause of food borne illness in the U.S. as this naturally occurring bacteria causing upwards of 1.35 million cases of foodborne illness annually. Cattle may harbor Salmonella in the gastrointestinal tract (GI) as well as in their lymph nodes and other areas of the animal body. This creates a challenge because lymph nodes are impervious to post-harvest pathogen interventions, thus leading to potential contamination in ground beef production. Direct-fed microbials are a possible pre-harvest intervention to reduce the burden of Salmonella. The objective of this study was to determine the efficacy of the direct-fed microbial 10-G upon cattle and carcass performance, as well as prevalence and enumeration of Salmonella in feces and lymph nodes. Fed beef heifers (n = 1,400; 343.3 ± 36.2 kg) were blocked by day of arrival and randomly allocated to one of two treatments (0 or 2g/animal/d; CON and 10-G, respectively) with ten pens per treatment. Pen served as the experimental unit. Cattle fed 10-G were provided 1 billion CFUs per animal per day of Lactobacillus acidophilus, Enterococcus faecium, Pediococcus pentosaceus, Lactobacillus brevis and Lactobacillus plantarum. Recto-anal mucosal swab samples (RAMS) and subiliac lymph nodes (SLN) were collected longitudinally at harvest from twenty-four heifers per pen (n = 476). Quantification of RAMS and SLN’s were completed via BAX® Salmonella PCR assay following the SalQuant™ approach. Data were analyzed using the GLIMMIX procedure of SAS; pen served as the experimental unit and block and harvest date were random effects. Heifers fed 10-G did not differ in dry matter intake (P = 0.78), final body weight
(P = 0.52), average daily gain (P = 0.49), gain to feed (P = 0.74), hot carcass weight (P = 0.56), dressed carcass yield (P = 0.83), 12th rib fat depth (P = 0.23), ribeye area (P = 0.62), calculated empty body fat (P = 0.35), or marbling score (P = 0.83). Distributions of liver scores (P > 0.14), yield grade (P > 0.22), and quality grade (P > 0.15) were not different between treatments. We detected a tendency for fewer inflated lungs at harvest of cattle fed 10-G (P = 0.10; 10-G 0.2%, CON 1.0%); other lung outcomes did not differ (P > 0.12). Salmonella prevalence of RAMS samples did not differ (P = 0.76; 10-G 93.7%, CON 93.3%) nor did SLN (P = 0.12; 10-G 22.7%, CON 12.2%). Salmonella log of CFU/g of RAMS and SLN did not differ between treatments at harvest (P = 0.49; 10-G 3.78, CON 3.37; P = 0.12; 10-G 0.35, CON 0.08), respectively. These results do not demonstrate any improvement live animal performance, carcass characteristics or reduction in Salmonella for heifers fed 10-G

The Amarillo Symphony: The First 100 Years
Get PDFThe data presented on this poster is gathered from Mrs. Lavon Aaronâ's history of the first fifty years of the Amarillo Symphony, which she compiled in 1974 as well as that contained in primary sources in the Panhandle Plains Historical Museum, newspaper articles published in Amarillo newspapers, and programs held in the archives of the Amarillo Symphony.The Amarillo Symphony: The First 100 Years will be a book that explores the rich history of the Amarillo Symphony Orchestra, one of the Panhandle's longest standing cultural institutions. The volume will celebrate the organization as the result of the hard work and eager support of Amarillo's citizens and calls attention to Amarillo's stature as a cultural center of the American Southwest in spite of its position as a small city located in the center of the Texas Panhandle a great distance from neighboring metropolitan centers. Moreover, this project will encourage the exploration of musical cultures of the many other small cities scattered throughout the rural regions of Texas, communities whose ardent and local support of the arts has been largely ignored on national stage
Reimagining the Mother Road with StoryMaps: Social Justice Work in Challenging Contexts
Get PDFThe data collection methodology used was community-based participatory research through narrative and geographic inquiry frameworks.Using the well-known Route 66 interstate highway, our StoryMap team, led by women of color, created an interactive, multimedia mentor text for public school teachers interested in creating learning that produces place-based projects. Teachers interested in equity and justice for their marginalized students, particularly those in censorious or condeming areas, can find inspiration for similar projects of place-conscious teaching as a subversive activity (Postman & Weingartner, 1969). These tools draw upon the collective wisdom, hidden histories, and current contexts of the user/creator communities in rural Texas spaces. Rural equity matters: nearly 1 in 5 students, (9.3 million), attend rural schools where the buildings house the sole possibility for innovation in a community (Showalter, et al. 2017). This multimedia presentation highlights action-oriented work that is emergent and does not lend itself to narrow definitions, reside in district offices, or exist solely in professional development focused on anti-bias training. It creates and supports an intentional disposition "to see the invisible structures, policies, and behaviors that sustain unequal outcomes and interrupt the ways of working that serve, implicitly or explicitly, to perpetuate gaps in opportunity for vulnerable communities" (Cheatham, et al., 2020). Localized, hidden histories made visible help to "disrupt patterns of inequity...[in] a community's history of oppression [and] helps highlight the historic wounds that need healing, wounds that continue to hurt" (DeWolf and Geddes, 2019). Along these lines, those who research their communities become architects of local historicity built among a place’s myths, legends, and flattering fictions
