Wet Distillers Grains

Abstract One hundred twenty individually fed steers (initial BW 283 kg ± 32) were utilized in an 84-d growing trial to evaluate effects of increased metabolizable lysine from non-enzymatically browned soybean meal (SoyPass) in grass hay-based diets containing wet distillers grains plus solubles (WDGS). The treatments were arranged as a 2 × 3 factorial with two levels of protein supplement as 20% (low; DL20) or 35% (high; DL35) of dietary DM using WDGS as the basal protein source, and three increments of SoyPass (SP) replacing 0%, 30%, or 60% of the WDGS DM in the protein supplement yielding six dietary treatments. Average daily gain (ADG), dry matter intake (DMI), gain:feed (G:F), and plasma urea N (PUN) data were analyzed using the MIXED procedure of SAS as a 2 × 3 factorial. Animal was the experimental unit and fixed effects included body weight block, dietary inclusion of distillers grains (DL20, DL35), dietary inclusion of SoyPass (SP) (3 levels), and DL × SP inclusion interactions. Linear and quadratic interactions between DL and SP inclusion were analyzed using covariate regression . No interactions were detected for ADG between SP and DL (P = 0.76). Additionally, SP had no effect on ADG (P = 0.49). However, ADG was increased for steers consuming the DL35 diet compared to DL20 (1.13 vs. 0.86 kg/d, respectively; P < 0.01). A DL × SP interaction was detected for dry-matter intake (DMI; P = 0.01). As SP replaced WDGS in the DL35 diet, DMI increased linearly from 8.10 to 8.93 kg/d (P = 0.02). In the DL20 diet, DMI was not different as SP replaced WDGS (P ≥ 0.11). Therefore, G:F tended to decrease linearly (P = 0.06) as SP replaced WDGS in the DL35 diet, while no difference (P ≥ 0.11) was detected in the DL20 diet, suggesting SP contained less energy than WDGS but did improve dietary lysine balance. Furthermore, plasma urea nitrogen (PUN) increased linearly as SP replaced WDGS in the DL20 diet (P < 0.01) but was not affected by SP substitution in the DL35 diet (P ≥ 0.19). When WDGS is fed at a low (20% DM) or high (35% DM) inclusion rate in a forage based diet, replacing the distillers with a source of protected amino acids supplied through heat-treated soybean meal, did not improve performance. A more concentrated or energy dense form of amino acids may be beneficial in forage-based growing cattle diets containing 20% distillers grains, but is not needed in diets with 35% distillers grains.

Urea Inclusion

Abstract Crossbred beef steers (n = 384) were utilized to evaluate the effects of adding urea to a dry rolled corn based finishing diet containing low inclusions of wet distillers grains plus solubles (WDGS). Treatments were set up as a 2 × 4 factorial arrangement with factors consisting of WDGS inclusion at either 12 or 20% of diet dry matter (DM) and urea inclusion at either 0, 0.4, 0.8, 1.2% of diet DM. Cattle were blocked and stratified by initial body weight (BW) and assigned randomly to treatment. The heavy block of cattle were harvested after 160 d on feed (DOF) and the middle and light blocks of cattle were harvested after 179 DOF. The model include the fixed effects of weight block, WDGS inclusion, urea inclusion, and their interactions. There were no significant interactions (P > 0.12) observed between WDGS inclusion and urea inclusion in the diet; therefore, only main effects are discussed. Increasing inclusion of WDGS improved (P < 0.04) carcass adjusted ADG and G:F. Dry matter intake was reduced (P = 0.04) with increasing WDGS inclusions. Fat thickness was increased (P = 0.04) with increased WDGS inclusion; however, no other carcass characteristics were significantly affected by WDGS inclusion. Cubic effects of urea inclusion were observed (P < 0.05) for HCW, final BW, ADG, and DMI on a carcass adjusted and live BW basis; however, cubic effects with increasing urea inclusion are of minimal biological relevance. There were no linear or quadratic responses (P > 0.11) for increasing urea inclusion in the diet for performance measurements or carcass characteristics. Increasing WDGS inclusion in the diet improved performance. Added urea in the diet had minimal impact on performance, regardless of wet distillers grains plus solubles inclusion.

Abstract One hundred twenty individually fed steers (initial BW 283 kg) were utilized in an 84-d growing trial to evaluate effects of increased metabolizable lysine from non-enzymatically browned soybean meal (SoyPass) in grass hay based diets containing wet distillers grains plus solubles (WDGS). Treatments were arranged as a 2 × 3 factorial design with two levels of WDGS (20% or 35% of DM) and three levels of supplemental SoyPass replacing 0%, 30%, or 60% of WDGS. The statistical model included animal as the experimental unit and level of WDGS and SoyPass substitution were included as fixed effects. Covariate regression was used to test for linear and quadratic interactions between WDGS and SoyPass substitution. No interactions were detected for ADG between SoyPass supplementation and level of WDGS in the diet (P = 0.76). Additionally, SoyPass inclusion had no effect on ADG (P = 0.49). However, ADG was increased for steers consuming the 35% WDGS diet compared to steers offered the 20% WDGS diet (1.13 vs. 0.86 kg/d, respectively; P < 0.01). A SoyPass × WDGS interaction was detected for DMI (P = 0.01). As SoyPass replaced WDGS in the 35% diet, DMI increased linearly from 8.10 to 8.93 kg/d (P = 0.01). In the 20% WDGS diet, DMI decreased as SoyPass replaced 60% of the WDGS compared to 30% (7.68 vs. 8.36, P = 0.02). Therefore, G:F decreased linearly (P = 0.01) as SoyPass replaced WDGS in the 35% treatment and increased quadratically (P = 0.02) for the 20% WDGS treatment. Furthermore, BUN increased linearly as SoyPass replaced WDGS in the 20% diet (P = 0.01) but was not affected by SoyPass substitution in the 35% diet. Overall, results indicate forage-based growing diets formulated with low-levels of WDGS (< 20%) may be deficient in metabolizable lysine, which could be supplied with SoyPass.

Abstract This study was conducted to determine the effect of pelleting on the digestibility of corn-soybean meal-based diet in growing pigs. Two trials with 6 pigs cannulated at the distal ileum were conducted. In each trial, pigs were assigned to each treatment following a crossover design. In each experiment, the same diet, composed of corn and soybean meal with 10% wheat from two different feed mills, was served in pellet or mash form. Pelleting allowed an increase in digestibility in one of the trials. Apparent ileal digestibility (AID) of dry matter (DM), crude protein (CP) and digestible energy (DE) were improved with pelleting by 8, 12 and 9% (P&lt; 0.01). The AID of amino acids (AA) was also improved (P&lt; 0.05). Apparent total tract digestibility (ATTD) was increased by pelleting in DM, CP and DE by 5, 7 and 6% respectively (P&lt; 0.01). The digestibility of the mash diet in experiment 1 was lower than in the pelleted diet in the experiment 1 and both diets in experiment 2 as shown by the interaction Pelleting X Trial which was significant for the AID and ATTD of DM, CP and DE (P&lt; 0.01). Therefore, in experiment 1, pelleting allows to improve the digestibility of diet to the same level as in experiment 2. The AID of CP was higher by 37% in the mash diet from the second experiment compared to the one in the first experiment. Even though the same ingredients were chosen in the two experiments, this shows the variability in digestibility existing between different feed mills and ingredient sources. This difference was not observed in pelleted diets. The results obtained in these two trials show that pelleting can reduce the variability of digestibility and then give a good digestibility of diets even if the ingredients are of different quality or sources.

Abstract Two experiments were conducted to determine the effects of increasing levels of soybean meal (SBM) replacing feed grade amino acids in corn or corn-dried distillers grains with solubles (DDGS)-based diets on growth performance of late finishing pigs. In both experiments, there were 22 to 27 pigs per pen and 14 pens per treatment. Average length of the experiments was 35 (Exp. 1) and 29 days (Exp. 2). Diets were balanced to contain 0.70% SID Lys and 2,667 or 2,610 kcal NE/kg for Exp. 1 and 2, respectively. Minimum amino acid ratios relative to Lys were: Ile, 55; Met&Cys, 60; Thr, 65; Trp, 19.5, and Val, 70. Dietary crude protein ranged from 10.1 to 15.2 for Exp. 1 and 13.6 to 19.4 for Exp. 2. The statistical model considered fixed effects of treatment, linear and quadratic contrasts, and random effect of block. In Exp.1, 1,793 pigs (L337×1050, PIC; initially 104.9 ± 1.4 kg) were fed corn-based diets and pens of pigs were assigned to 1 of 5 dietary treatments with increasing SBM from 5 to 20%. Overall, average daily gain (ADG) and gain-to-feed (G:F) increased (linear; P &lt; 0.05) as SBM increased with the greatest improvement observed as SBM increased from 5 to 8.75%, with little improvement thereafter. In Exp. 2, 1,827 pigs (L337×1050, PIC; initially 97.9 ± 1.1 kg) were used in a similar study as Exp. 1, but all diets contained 25% DDGS and SBM levels increased from 0 to 16%. Overall, G:F and final bodyweight of pigs marginally improved (linear and quadratic, respectively; P &lt; 0.10) as SBM increased, with the greatest performance observed when diets contained 8% SBM. These results suggest that increasing SBM up to 8% at the expense of feed grade amino acids in corn or corn-DDGS-based diets improved ADG or G:F in late-finishing pigs.

The aim of this study was to determine the influence of leucine supplement in the form of rumen-protected tablets on milk yield and composition and plasma amino acids in four high-yielding lactating Holstein cows. The experiment was carried out as a cross-over procedure and was divided into 4 periods of 14 d (10 d preliminary period and 4 d experimental period). Cows were fed ad libitum a diet based on maize silage, lucerne hay and a supplemental mixture. The diet, defficient in methionine, lysine, and leucine, was supplemented with methionine+lysine (Control) or methionine+lysine+leucine (Leu) in rumen protected form. The dry matter intake, milk yield and milk yield expressed in energy corrected milk did not differ significantly between the treatments. Milk protein content and yield did not show statistically significant variation. The contents and yield of casein, fat, lactose and urea were unaffected by the treatment. Blood metabolites did not vary between the treatments. The introduction of Leu resulted in higher plasma levels of proline (p
