Abstract The objective of this pooled analysis was to evaluate the effect of Syngenta Enogen Feed Corn (SYT-EFC) and corn processing methods with byproducts on finishing cattle performance and carcass characteristics. Treatment factors consisted of SYT-EFC or commercial corn (CON) processed as dry-rolled (DRC) or high-moisture corn (HMC). Byproduct comparisons were 0, 18, or 30% distillers grains inclusions or with 30% Sweet Bran to determine if SYT-EFC effect was impacted by byproducts. Seven trials (n = 2,340 steers; initial BW = 327 ± 20 kg) consisting of 252 pen means with 12 treatments were analyzed utilizing contrasts. Feeding SYT-EFC as DRC resulted in heavier final BW (P ≤ 0.03) and greater 12th rib fat (P < 0.01) compared to CON. There was a linear interaction between hybrid and distillers for G:F (P < 0.01). As distillers increased, G:F improved at a greater rate for CON compared to SYT-EFC. Feeding SYT-EFC as DRC with increasing distillers was not significantly different (P ≥ 0.68) from CON for G:F, but was 3% better than CON with 0% distillers. Feeding SYT-EFC as DRC with 18% distillers resulted in heavier final BW (P < 0.01) compared to 0 or 30% distillers. Feeding SYT-EFC as DRC with Sweet Bran resulted in heavier final BW (P ≤ 0.02) and greater ADG (P < 0.01) compared to CON. This increase in ADG with no difference in DMI, resulted in SYT-EFC diets having a 5.08% increase in feed efficiency (P < 0.01). The improvement for the corn is calculated to be 9.58% (5.08 / 0.53) when SYT-EFC was fed with Sweet Bran compared to a CON corn hybrid. No positive effects were observed when SYT-EFC was processed as HMC. These data suggest that SYT-EFC is better than CON hybrids when distillers inclusion is low or when fed with Sweet Bran.

Abstract Two experiments evaluated the effects of feeding a new corn hybrid, containing an α-amylase enzyme trait, Syngenta Enogen Feed Corn (SYT-EFC), on feedlot performance and carcass characteristics at two locations. Experiment 1 utilized 300 calffed steers (298.5 ± 16.3 kg of BW) at the University of Nebraska–Lincoln Eastern Nebraska Research and Extension Center Mead, NE. Treatments were designed as a 2 × 2 + 1–factorial arrangement with factors consisting of 1) corn type (SYT-EFC or conventional [CON]) and 2) byproduct type (with or without Sweet Bran [SB]), or a BLEND of STY-EFC and CON without SB. In Exp. 2, 240 crossbred, calf-fed steers (287.6 ± 15.4 kg of BW) were utilized at the University of Nebraska–Lincoln Panhandle Research and Extension Center near Scottsbluff, NE. Steers were fed SYT-EFC, CON, BLEND, or CON with a commercial α-amylase enzyme supplement (CON-E). In Exp. 1, there was an interaction for ADG (P = 0.05) and G:F (P = 0.02). Steers fed SYT-EFC with SB had greater ADG and G:F than CON; however, in diets without SB, SYT-EFC and CON were not different resulting in a 10.1% change in G:F when steers were fed SYT-EFC in SB compared with CON and only 1.6% change between SYT-EFC and CON without SB. Energy values, based on performance data, resulted in a 6.5% and 8.3% change in NEm and NEg, respectively, for steers fed SYT-EFC and CON with SB and 1.6% change for both NEm and NEg for steers fed SYT-EFC and CON without SB. For the main effect of corn trait, steers fed SYT-EFC had greater marbling scores, fat depth, and calculated yield grade compared with CON (P ≤ 0.03). In diets without SB, there was no difference between SYT-EFC, CON, or BLEND for DMI, final BW, ADG, G:F, NEm, or NEg (P ≥ 0.35). In Exp. 2, cattle fed SYT-EFC, BLEND, or CON-E had greater final BW, ADG, and G:F than cattle fed CON (P ≤ 0.03). On average, NEm and NEg were 4.9% and 7.0% greater, respectively, for steers fed amylase enzyme treatments compared with CON (P ≤ 0.01). Hot carcass weights were greater in steers fed α-amylase treatments compared with CON (P < 0.01). Feeding Syngenta Enogen Feed Corn, which contains an α-amylase enzyme trait, at both locations improved feed efficiency in finishing cattle diets containing WDGS or SB.

Abstract An experiment was conducted to evaluate the effect of grain type and wet distillers grains inclusion on finishing cattle performance and carcass characteristics. Yearling steers (n = 320; initial BW = 325 ± 23 kg) were utilized in a 2 x 2 factorial arrangement, with the first factor as grain type at either 100% dry-rolled corn or a 50:50 blend of dry-rolled wheat and dry-rolled corn, and the second factor as wet distillers grains plus solubles (WDGS) inclusion at 12 or 30% of diet DM. There were no interactions between grain type and WDGS inclusion levels (P ≥ 0.21), contrary to our hypothesis that 50:50 wheat blend would improve performance with increased WDGS. There were no differences in DMI, ADG, or G:F (P ≥ 0.29) between 100% DRC or 50:50 blend of DRC and wheat. There was no difference in HCW between grain types (P = 0.84), but LM area was greater (P = 0.02) for steers fed a 50:50 blend of DRC and wheat. There were no differences in 12th rib fat or USDA marbling score between grain types (P ≥ 0.15), but increased LM area in steers fed the blended diet led to improved calculated yield grade (P = 0.04). Increasing WDGS in the diet increased carcass-adjusted final BW (P = 0.03) and improved carcass-adjusted ADG and G:F by 3.8% (P ≤ 0.05). Feeding 30% WDGS increased HCW by 10.9 kg (P = 0.03) and increased 12th rib fat (P = 0.02) compared to feeding 12% WDGS. There were no differences in LM area, USDA marbling score, or calculated YG between WDGS inclusions. These data suggest that increasing WDGS in the diet improves performance regardless of grain type and depending on price, wheat can replace up to 50% of the grain portion of the diet without affecting performance.

Abstract A feedlot study was conducted comparing a natural feed additive at varying corn silage (CS) inclusions on receiving and finishing cattle performance. The study utilized 480 crossbred steers (initial shrunk body weight [BW] = 296 kg; SD = 24.1 kg) in 48 pens with 10 steers/pen and 8 pens per treatment. Treatments were designed as a 2 × 3 factorial with 3 inclusions of CS (14%, 47%, 80%; dry matter [DM] basis) with or without (+, −) the inclusion of a feed additive containing fumaric acid and palm oil (FAPO). All treatment diets contained 16% modified distillers grains plus solubles and 4% supplement with dry-rolled corn replacing CS on a DM basis. All steers were fed the 80 CS diet and adapted to 47% and 14% CS over a 10- and 24-d period, respectively. Cattle fed 80 CS were fed for 238 days, 47 CS for 195 days, and 14% CS were fed for 168 days to a common backfat of 1.28 cm (P ≥ 0.59). There were no interactions for CS inclusion and the inclusion of FAPO on final body weight (FBW), DMI, ADG, G:F, hot carcass weight (HCW), LM area, marbling, or calculated yield grade (CYG; P ≥ 0.15). There was no significant difference for FBW, DMI, ADG, G:F, HCW, marbling, or CYG for cattle fed with or without FAPO (P ≥ 0.13). However, there was a quadratic response for FBW, ADG, G:F, HCW, marbling, and CYG with increased inclusion of CS (P ≤ 0.04). Inclusion of FAPO had no effect on performance. Feeding CS at greater inclusions decreased daily gain and feed efficiency but increased FBW when fed to an equal fat endpoint. CS gave greater returns ($/animal) when fed at 80% of diet DM. Feeding greater amounts of CS can be an economical way to finish cattle. In this study, FAPO did not affect animal performance, carcass characteristics, or economic return.

Abstract Environment and weather may have a significant impact on feedlot cattle growth. Most U.S. feedlot cattle are finished/fed in open-mound, dirt lots. Historic closeout data conclude that cattle performance has been optimal when finishing cattle in well groomed, dry, dirt mound lots. However, weather challenges including excessive heat, cold, or moisture conditions negatively impact cattle performance. Past attempts to provide shelter for finishing feedlot cattle with buildings/sheds have often yielded subpar finishing cattle growth expectations when compared to well-groomed dirt mounds. Improved cattle housing designs including building ventilation and flooring types are being utilized in many Northern Plains and Midwest cattle operations during the last decade. This symposium will address current designs, management issues, economic considerations and future improvement challenges for finishing cattle housing systems. Performance and economics comparing various cattle breeds and varied in-weights throughout finishing period in differing cattle facilities will be evaluated. Comparison of expected and realized performance of finishing cattle when housed in bedded barns, conventional scrape yards with sheds and cattle comfort finishing shelters will be reviewed.

Abstract Background This study aims to optimize the therapeutic regimen for refractory obstructive meibomian gland dysfunction (o-MGD) patients by combining intraductal meibomian gland probing (MGP) and intense pulsed light (IPL) to enhance their positive effects and reduce their limitations. Methods This randomized, assessor blind study includes 45 patients (90 eyes) with refractory o-MGD who were divided into 3 groups via allocation concealment: IPL (group I, received an IPL treatment course: 3 times at 3-week intervals), MGP (group II, received MGP one time), and combined MGP-IPL (group III, MGP first followed by an IPL treatment course). Standard Patient Evaluation of Eye Dryness score (SPEED), tear break-up time (TBUT), corneal fluorescein staining (CFS), meibum grade, and lid margin finding results were assessed at baseline, 3 weeks after final treatment for groups I and III, 3 and 12 weeks after MGP for group II. Six months after final treatment, the SPEED and willingness to receive any treatment again were also collected for all groups. Paired Wilcoxon, Mann-Whitney U with Bonferroni correction, and Kruskal-Wallis tests were used for data analysis. Results For all 3 groups, all previously mentioned indexes improved significantly following treatment (P<0.01). MGP-IPL was better than IPL and MGP in terms of post-treatment SPEED, TBUT, meibum grade, and lid telangiectasia (P<0.05/3). Furthermore, the MGP-IPL was better than IPL in terms of lid tenderness and better than MGP in terms of orifice abnormality (P< 0.05/3). Six months later, the SPEED for the MGP-IPL was also significantly lower than other groups (P<0.05/3). Moreover, no patients in the MGP-IPL group expressed the need to be treated again compared to 35.7% or 20% of patients in the IPL or MGP groups, respectively. Conclusions Compared with IPL or MGP alone, the combination MGP-IPL produced best results in relieving all signs and symptoms and helping patients attain long-lasting symptom relief.
