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 alpha-amylase enzyme has the potential to increase starch digestibility, thus improving feedlot cattle performance and efficiency. The objective of this experiment was to evaluate the addition of an alpha-amylase enzyme on two steam-flaked bulk densities and subsequent performance of finishing beef steers. Forty-eight crossbred steers (325 ± 19 kg), were used in a complete randomized block design with a 2 × 2 factorial treatment design. Factors were corn processing and enzyme addition. Dietary treatments were steam-flaked corn-based diets with two bulk-flake density weights of corn (0.32 kg/L vs. 0.39 kg/L). Experimental treatments were 1) 0.32 kg/L with no enzyme (32NE), 2) 0.39 kg/L with no enzyme (39NE), 3) 0.32 kg/L with enzyme (32E), and 4) 0.39 kg/L with enzyme (39E) on a DM basis. The enzyme was applied at 0.50 kg/T of steam-flaked corn (As-fed basis). Data were analyzed using a mixed model with fixed effects of flake weight, enzyme, and flake weight × enzyme interaction. Throughout the feeding period, starch availability for 0.32 kg/L and 0.39 kg/L corn averaged 60.7% and 42.2%, respectively. Steers receiving the alpha-amylase enzyme had no differences in BW (P ≥ 0.62), ADG (P ≥ 0.55), and DMI (P ≥ 0.56) compared to NE steers. Furthermore, carcass characteristics did not differ (P ≥ 0.26) between E and NE steers. Feeding an alpha-amylase enzyme to finishing cattle had no detrimental effects on performance or carcass characteristics. Overall, a more highly processed corn was observed to decrease dry matter intake and increase the potential for digestive upsets. This may limit the use of the alpha-amylase enzyme to a lesser processed corn.

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.

Alfalfa Silage

Two experiments were conducted to evaluate the effects of monensin with growing and finishing cattle. In experiment 1, 80 Hereford steer calves were fed two different silage rations. With alfalfa silage, monensin increased weight gains (+12%) and feed efficiency (P < 0.05) (+11%). When high moisture (HM) shelled corn was fed along with alfalfa silage, monensin had no effect on weight gains, but increased feed efficiency (P < 0.05) (+12%) largely by decreasing (P > 0.05) feed intake. In experiment 2, 72 steer and heifer crossbred calves were fed corn silage for 112 days followed by high levels of HM shelled corn through to marketing at a constant finish. Over an average total of 258 days on feed, monensin increased (P < 0.05) rate of gain (+9%) as well as feed efficiency (+13%). Monensin produced no effects on carcass characteristics. At least part of the improvement in feed efficiency could be attributed to altered ruminal fermentation. Molar percentage of propionic acid was increased (P < 0.05) and butyric and acetic acid decreased (P < 0.05) with monensin feeding.

Abstract There is strong interest in feeding cattle in Missouri, but climatic extremes warrant exploring indoor management systems. Therefore, our objective was to compare performance and carcass characteristics of finishing beef heifers managed in a bedded hoop barn versus an open feedlot. On February 14, 2018, a total of 60 (297.5 ± 34.53 kg BW) crossbred beef heifers were allocated randomly to two pens (4.8 m2 per head) in a hoop-barn (Indoor; n = 30) and to two pens (27 m2 per head) in an open feedlot (Outdoor; n = 30). Heifers had ad libitum access to a commercial feedlot ration and water. Heifers were weighed at the start, approximately every 30 d, and at the end of the study and then were transported and harvested in two groups based on visual BF evaluation at a commercial abattoir. Data were analyzed using PROC MIXED of SAS. Start and final BW and final gain did not differ (P ≥ 0.32) between treatments. However, d 28 BW, final ADG, and d 119 gain tended (P ≤ 0.12) to be greater from Indoor compared to Outdoor. Also, d 58, d 89, and d 119 BW and d 28, d 58, d 89, and d 119 ADG, and d 28, d 58, and d 89 gain were greater (P ≤ 0.07) from Indoor compared to Outdoor. All carcass measurements were similar (P ≥ 0.40) between treatments. Therefore, finishing cattle in a bedded hoop barn may improve some performance measurements without impacting carcass quality and yield attributes. Hoop barns appear to be a viable consideration for finishing beef cattle in Missouri. This project was funded by the Missouri Department of Agriculture’s Missouri Agricultural Foundation Beef Initiative Grant Program.
