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.

High Moisture Corn

Abstract Steers (n=600; Initial BW = 402 ± 17 kg) were fed for134 day to evaluate the effect of milling method and corn type on performance and carcass characteristics. Treatments were evaluated as a 2 × 3 factorial with factors being milling method (Automatic Ag® roller mill or hammer mill) and corn type (100% high-moisture, 100% dry, or 50:50 blend of high-moisture and dry corn). High-moisture corn was processed at harvested based on respective treatment and ensiled until trial initiation. Both dry corn and HMC were processed using a 16-mm screen in the hammer mill and the roller mill was adjusted to ensure all kernels were broken. There were no interactions between milling method and corn type for final BW, daily gain (ADG), or dry matter intake (DMI; P ≥ 0.32), but there was a tendency for an interaction for G:F (P = 0.09). Cattle fed 100% high-moisture corn processed with the Automatic Ag roller mill were 4.7% more efficient (P ≤ 0.01) with 55% lower fecal starch (P &lt; 0.01) compared to high-moisture corn processed with the hammer mill. Cattle fed dry corn tended (P = 0.07) to have a greater live final BW regardless of milling type and had the greatest DMI (P ≤ 0.01) Intake decreased as high-moisture corn was increased in the diet. Due to no differences in ADG with lower DMI led to a 6% improvement (P ≤ 0.01) in G:F for steers fed HMC. There were no further effects (P ≥ 0.14) on performance or carcass traits regardless of milling method or corn type. Processing high-moisture corn using Automatic Ag roller mill improved feed efficiency compared to processing with a hammer mill when corn was included at 70% of the diet, but processing method had little effect when fed as dry corn or blended diets.

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 &lt; 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.

Three experiments were conducted to determine the effects of monensin on feed intake, rate of gain and feed efficiency of a total of 198 Holstein steers. In experiment I, 72 steers were fed ground ear corn and corn silage diets containing 0 (treatment 1), 22 (treatment 2) and 33 (treatment 3) g/tonne DM monensin for 112 days. Treatments 2 and 3 received 11 g/tonne DM monensin for the first 28 days. Daily gains were not significantly different (P > 0.05) throughout the trial and intake was slightly reduced (P > 0.05) with monensin addition. Feed efficiency in treatments 2 and 3 were improved 5.5 and 8.8% respectively, but only treatment 3 was significantly (P < 0.05) better than treatment 1. Rumen fluid from steers fed treatment 3 contained a higher proportion (P < 0.05) of propionic acid and a lower (P < 0.05) A:P ratio than did rumen fluid from treatment 1. Levels of acetic and butyric acid were reduced (P > 0.05) by monensin inclusion. In experiment II, 46 steers were fed hay crop silage and shelled corn diets containing 0 (treatment 1) and 33 g/tonne DM (treatment 2) monensin for 112 days. Gains were slightly (P > 0.05) higher and intake slightly (P > 0.05) lower on treatment 2. Monensin improved (P > 0.05) feed efficiency by 8.5%. In experiment III, 40 purchased and 40 station-reared steers were assigned by origin, in pairs, to 40 Calan electronic headgates. A 23 factorial experimental design was used to evaluate the effect of diet with or without monensin used separately and in combination with progesterone-estradiol implants. Steers were fed a high moisture ear corn and corn silage diet for 84 days. No 3-factor interactions (P > 0.05) were detected. Implant treatments gained significantly (P < 0.05) faster than either control or monensin alone. Intake was significantly (P < 0.05) lower in treatments fed monensin. Feed efficiency was improved (P < 0.05) 16% with both monensin and implant, 10% (P < 0.05) with monensin alone, and 6% (P > 0.05) with implant alone over control.

Treatments of high moisture shelled corn were compared in diets containing approximately 60% (dry matter (DM) basis) corn silage. In an initial digestibility trial, treatments were: (1) ensiled, ground; (2) 1.5% (wt/wt) mixture of acetic: propionic acid, whole; (3) 2% (wt/wt DM basis) anhydrous ammonia, whole. Treatments were evaluated with six yearling steers in a double 3 × 3 latin square design. Urea was included in the ensiled and acid-treated corn diets to supply sufficient nitrogen. Ammoniating whole corn resulted in similar starch and energy digestibilities compared to ensiled ground corn. However, a large decrease in starch digestibility occurred with acid-treated whole corn. Digestibility of acid detergent fiber was greater (P < 0.05) with both ammoniated and acid-treated whole than ensiled ground corn. In a feedlot trial, two high moisture corn treatments compared were: (1) ensiled, ground; (2) 3.7% (wt/wt DM basis) urea, whole. Eighty Hereford yearling steers compared the two corn diets each with or without monensin. Temperatures rose steadily within bins plateauing approximately 21/2 wk after storage. The amount of urea that hydrolyzed to ammonia varied depending upon location within bins. A total of 1.4% DM loss occurred during storage. Urea-treatment tended to slightly reduce liveweight gain and feed efficiency. Monensin decreased intake (P < 0.05) and slightly improved feed efficiency (P > 0.05) with both types of corn. Effects of monensin on rumen VFA were similar with both corn diets. Type of corn had no effect on rumen VFA proportions.

Abstract The objective of this study was to evaluate the effect of feeding Aspergillus ssp. blend in combination with dry-rolled (DRC) or high-moisture corn (HMC) based finishing diets on performance and carcass characteristics. Crossbred beef steers (n = 320; initial BW = 267 ± 9 kg) were utilized in a generalized randomized block design. Cattle were assigned randomly to pens by initial body weight (BW) and pens were assigned randomly to one of four treatments with 8 pens per treatment for simple effect means. Treatments were set up as a 2 × 2 factorial arrangement with factors consisting of corn processing and 0 g / steer daily or 10 g / steer daily Aspergillus ssp. blend. There were no significant interactions (P ≥ 0.23) observed between corn processing and Aspergillus ssp. blend in the diet; therefore, only main effects are discussed. For the main effect of Aspergillus ssp. blend; no significant differences were observed for dry-matter intake (DMI), average daily gain (ADG), feed efficiency (G:F), hot carcass weight (HCW), or carcass traits (P ≥ 0.78). Cattle fed Aspergillus ssp. blend had a greater 12th rib fat (P = 0.05). For the main effect of corn processing, cattle fed DRC had heavier HCW and final BW (P = 0.04), greater ADG (P = 0.05), and greater DMI (P &lt; 0.01). However, steers fed HMC had greater G:F (P &lt; 0.01) compared to DRC. These data suggest that feeding Aspergillus ssp. blend in either with dry-rolled or high moisture corn diets did not significantly improve performance or carcass characteristics in finishing beef steers. While feeding HMC improved feed efficiency compared to DRC, feeding DRC increased ADG (and also DMI) compared to HMC.

Three separate experiments were conducted to investigate performance of light-weight calves fed corn silage supplemented with different non-protein nitrogen (NPN) sources added at ensiling time. In one experiment NPN was also added at feeding time. For calves up to approximately 290 kg body weight all supplements containing only NPN reduced weight gains by approximately 0.10–0.15 kg/day compared to soybean meal or low-urea supplements. Corn silage treated with NPN silage additives resulted in reduced dry matter intake compared to soybean meal supplementation. Thus, the effect on feed efficiency was not as great as on weight gains. Treated silages tended to be higher in pH and lactic acid but lower in acetic acid content. A large portion of the NPN added at ensiling time was analyzed as ammonia in the silages. Also, true protein content of the treated silages tended to be higher than that of the controls.

A trial was conducted to evaluate graded levels of wheat-based dried distillers’ grains with solubles (DDGS) on feedlot performance and carcass characteristics of growing and finishing cattle. Two hundred weaned calves (290 ± 17 kg) were randomly assigned to 1 of 20 pens and fed one of five DDGS treatments. The barley grain-based control diet (0% DDGS) was formulated to 12% crude protein (CP) and 1.52 and 0.93 Mcal kg-1 net energy maintenance (NEm) and net energy gain (NEg) respectively, during the backgrounding period and 1.90 and 1.26 Mcal kg-1 NEm and NEg respectively, during finishing. Wheat-based DDGS replaced (DM basis) barley grain at levels of 8, 16, 24 and 32% during backgrounding and 6, 12, 18 and 23% during finishing. Over the 85-d backgrounding period, dry matter intake (DMI) (P = 0.02), average daily gain (ADG) (P = 0.04), and ultrasound (US) l. dorsi gain (P = 0.02) exhibited a cubic response to DDGS inclusion level with theoretical minima at 6.9, 8.1 and 6.9% DDGS, respectively, and theoretical maxima responses at 27.2, 30.8 and 23.9% DDGS, respectively. Feed efficiency exhibited a quadratic response (P = 0.02) to DDGS inclusion level with a theoretical poorest response at 13.1% DDGS. No effect (P > 0.05) of DDGS inclusion level was noted on ADG, DMI or feed efficiency (kg gain:kg feed; FE) during the finishing period. Similarly, carcass traits were not influenced (P > 0.05) by DDGS inclusion level. The results of this study indicate that wheat-based DDGS can serve as an effective replacement for barley grain in cattle diets supplying both energy and protein and that for finishing cattle, wheat-based DDGS has an energy value at least equal to that of barley grain when fed at levels up to 23% of the diet DM. Key words: Wheat-based dried distillers' grains with solubles, growing and finishing cattle, performance and carcass quality
