The Individual

Abstract Feed additives are commonly used in finishing pig diets to improve growth performance and carcass characteristics; however, data is limited on the interaction of various feed additives. The objective of this study was to determine the individual and combined effects of a phytogenic feed additive (Aromex® Pro) and narasin (Skycis®) on finishing pig growth performance and carcass characteristics. The study was conducted at a commercial research facility using a RCBD with 4 dietary treatments: Control (no Aromex® Pro or Skycis®); Aromex (as Control with 90.7 g/ton Aromex® Pro); Skycis (as Control with 13.6 g/ton Skycis®); Aromex + Skycis (as Control with 90.7 g/ton Aromex® Pro and 13.6 g/ton Skycis®). Diets were based on corn, soybean meal, and corn germ meal and were fed using a 3-phase program. Diets were formulated to the same nutrient levels across treatments that met or exceeded nutrient recommendations (NRC, 2012), with the feed additive added at the expense of corn. Pigs were placed on test at 40.6 ± 4.7 kg and harvested in 2 equal groups at 122.4 ± 2.2 kg. Thirteen blocks were used with pens of 34 pigs for 1,768 total pigs. Data were analyzed using PROC MIXED of SAS with pen as the experimental unit, fixed effect of treatment, and random effect of block. There was no effect (P > 0.05) of treatment on start or end weights, overall ADG (live or carcass weight), overall ADFI, or any carcass characteristics. Overall G:F (live and carcass weight) for Aromex and Skycis was similar (P > 0.05) to each other and greater (P < 0.05) than Control. Aromex + Skycis had G:F (live and carcass weight) similar to Control and Aromex, but less than Skycis. In conclusion, including Aromex® Pro and Skycis® in finishing diets improved feed efficiency, but those effects were not additive.

Abstract The objective of this experiment was to evaluate the effects of a phytogenic feed additive (PFA-F, Digestarom® Finish, BIOMIN America Inc.) on growth performance and carcass characteristics of grow-finish pigs compared to a control, two commercial PFA products (A and B), and a ractopamine feeding program. Two hundred pigs (Choice Genetics, BW = 24.88 ± 0.53 kg) were randomly allotted to 5 dietary treatments and fed diets based on 4 dietary phases. Dietary treatments consisted of: CON, a corn-soybean meal based diet; RAC, 4.5 ppm Ractopamine HCl was added into CON for the last 21 d; PFA-A (commercial product A) was added into CON when pigs reached 90 kg of BW; PFA-B (commercial product B) was added into CON from 75 kg of BW; PFA-F was added into CON from the beginning (25 kg of BW). Body weight and feed disappearance were recorded at the end of each phase, and carcass traits were measured at the end of the trial. Data were analyzed using the Mixed procedure of SAS. No differences were observed from phase 1 to phase 3 among the treatments. At the end of phase 4, RAC had a higher (P < 0.05) BW than the CON, PFA-A, or PFA-B (127.5 vs.123.1 or 121.5 kg); however, no difference between RAC and PFA-F in BW (127.5 vs.124.0 kg) was found. Pigs fed PFA-F had a higher (P < 0.05) hot carcass weight than those of fed CON or PFA-B (93.0 vs. 88.8 or 88.8 kg). No differences were found in lean percentage, fat depth, and loin depth among the treatments. In conclusion, PFA-F (Digestarom Finish) supplementation resulted in similar growth performance and hot carcass weight when compared to a Ractopamine feeding program during the grow-finish period, whereas either commercial product A or B had significantly lower performance than feeding Ractopamine.

Abstract This study was conducted at a commercial research facility and utilized 1,092 finishing pigs (PIC® 337 × Camborough®) in a RCBD with 3 dietary treatments to determine the effects of commercially available phytogenic feed additives on growth performance traits in finishing swine for the last 35 d prior to marketing. The dietary treatments were as follows: 1) Control; 2) Aromex Pro® (AP; Delacon) fed at 0.01%; and 3) Ambitine® (AM; PMI) fed at 0.1%. Pens with 13 pigs/pen and 0.66 m2/pig were randomly allotted to treatments on the basis of live weight and gender. Pigs had ad libitum access to corn-soy diets that met or exceeded the pig’s requirements (NRC, 2012). Aromex Pro® and Ambitine® were added to the diets at the expense of corn. Dietary treatments started on day 0 (BW = 97.7 kg; SEM = 1.04) and were fed throughout the 35 d trial period. On d 21, the two heaviest pigs per pen were marketed, while the remaining pigs in each pen were marketed on d 35. Pigs and feeders were weighed on d 0, 21, and 35. Data were analyzed by using PROC MIXED of SAS® version 9.4, and pen was the experimental unit. The model included the fixed effect of treatment and random effect of replicate. Pre-planned orthogonal contrasts were used to compare AP vs. Control and AM vs. Control. Feeding AP or AM for the last 35 d in finishing both improved (P < 0.05) ADG by 4%, ADFI by 3% and final BW by 1.6 kg over Control, but did not change feed to gain or mortality. These data demonstrate that phytogenic feed additives can improve growth performance traits in finishing swine.

Abstract The aim of this study was to investigate the effects of a non-animal protein source in nursery diets on performance and carcass characteristics of wean to finish pigs. A total of 432 piglets with initial BW 6.31 ± 0.13 kg were blocked by BW and randomly assigned to 1 of 6 treatments. Treatments included PC1AP1: animal protein, nursery nutrient specifications without additives; PC2AP2: animal protein, growernutrientspecification without additives; NC1NP1: Non-animal protein, nursery specification without additives; NC2NP2: Non-animal protein, grower specification without additives; NC1 NP1 + FA[(Feed Additives)]: NC1 NP1 with additives; NC2 NP2 + FA: NC2 NP2 with additives. Feed Additives [Enzymes (Xylanase, β-Glucanase, Invertaseused), Oregano Essential Oil] were used in Treatments NP1 +FA and NP2 +FA. A linear model was used via the GLM procedure of SAS 9.4, with treatment as fixed effect and block as random effect. Pigs fed on the non-animal protein source and supplemented with feed additives had similar ADF, ADG, and G:F at finishing compared with treatment group on animal protein source (P > 0.05). No treatment differences (P > 0.05) for digesta, liver and serum based on a principal component AA analysis. (P>o.o5)[H2] No positive carry-over effects (P > 0.05) were found for performance except that pigs fed onthe animal protein source had greaterhad greater hot carcass weight (P < 0.05) than the non-animal protein group. In conclusion, wean pigs fed either animal or non-animal protein source at nursery had similar performance at finishing stage and similar carcass characteristics even though pigs on animal protein source had greater hot carcass weight relative to those on plant protein.

Abstract This study was conducted to determine the effects of a multi-species direct-fed microbial (DFM) product based on lactic acid bacteria and Bacillus subtilis on growth performance and carcass characteristics of grow-finish pigs. A total of 1,188 pigs (PIC 359 × 1050; initially 25.8 kg BW) were used in a 121-d growth trial with 27 pigs/pen and 22 pens/treatment. Pigs were allotted to treatments based on initial BW in a randomized complete block design. Treatments included a control diet and the control diet with added DFM (BiOWiSH Technologies Inc., Cincinnati, OH) included at 0.055% of the diet at the expense of corn. Diets were based on corn, distillers dried grains with solubles, and soybean meal and fed in four dietary phases. Data were analyzed using a linear mixed model (PROC GLIMMIX, SAS®) with treatment as fixed effect, block as random effect, and pen as experimental unit. Overall (d 0 to 121), pigs fed the control diet had greater ADG (P < 0.05) and final BW (P < 0.001) compared to pigs fed the DFM diet (Table 1). There was no evidence for differences (P > 0.05) in ADFI or G:F between treatments. The difference in final BW resulted in heavier (P < 0.05) HCW in control pigs compared to DFM pigs, but no evidence for differences (P > 0.05) was observed in carcass yield, backfat, loin depth, and percentage lean between treatments. In conclusion, the inclusion of this multi-species DFM in growing-finishing diets reduced ADG in this commercial study. This response could be related to inclusion rate, feeding duration, or other factors not identified in this study, warranting further research to characterize the effects on pig performance.

Abstract The objective of this experiment was to determine the effects of narasin (NAR; Skycis®; Elanco Animal Health, Greenfield, IN) or virginiamycin (VIR; Stafac®; Phibro Animal Health Corporation, Teaneck, NJ) on finishing pig growth performance and carcass characteristics. Two separate experiments were conducted at the same site in 2013 and 2014. A total of 576 pigs (initial BW = 23.2 ± 0.19 kg) were housed in 24 pens with 8 pigs per pen in Exp. 1. In Exp. 2, a total of 888 pigs (initial BW = 26.2 ± 0.12 kg) were housed in 39 pens with 8 pigs per pen. Treatments consisted of a series of unmedicated corn-soybean meal diets (CON), CON + NAR (15 mg/kg), or CON + VIR (11 mg/kg) fed for 108 d (Exp. 1) or 109 d (Exp. 2). Pen was the experimental unit in both studies. Data were analyzed as a randomized complete block design with the main effects of block and treatment (Exp. 1) and as an incomplete block design with the fixed effect of treatment and the random effects of barn and barn within block (Exp. 2). In Exp.1, NAR and VIR increased (P &lt; 0.05) ADG and ADFI from d 0 to 28, and BW on d 28, 56, 76 and 97 as compared to pigs fed CON. During day 0 to 28, pigs fed NAR had a greater (P &lt; 0.05) G:F than those fed CON or VIR. Also, during d 28 to 56 pigs fed VIR had a greater (P &lt; 0.05) ADFI than pigs fed CON. Pigs fed NAR or VIR had greater (P &lt; 0.05) carcass yield than those fed CON. In Exp.2, feeding NAR increased (P &lt; 0.05) pig BW from d 54 through 96 compared to pigs fed CON or VIR. No differences (P &gt; 0.05) in ADG were detected between pigs fed VIR and CON through the first 74 d, but ADG of pigs fed VIR was similar to (P &gt; 0.05) those fed NAR from d 26 to 54. From do 0 to 109, NAR improved ADG compared to pigs fed VIR, which also had similar gain to those consuming CON (P = 0.04). Feed efficiency was similar between pigs fed NAR and VIR with pigs fed CON intermediate (P = 0.05). Pigs fed NAR had a greater (P &lt; 0.05) HCW and loin depth than those fed CON or VIR. A subtherapeutic dose of VIR showed improvements in growth performance that were similar to NAR in one experiment. Although there were differences in the magnitude of growth and carcass effects of NAR between the two studies, pigs fed NAR showed at least a tendency to have greater G:F and in some cases increased carcass weight and yield compared to pigs consuming nonmedicated feed.

Abstract The effects of dietary feed additives (single or combination) on feeding behavior of feedlot cattle, and the representativeness of one individual animal within the experimental unit were evaluated. Crossbred-Angus beef steers (n = 240; initial BW = 319 ± 29 kg) were used in an randomized complete block design (block = BW), 4 steers/pen (experimental unit; n = 12/treatment), and randomly assigned to the following treatments: 1) no feed additive; 2) monensin (300 mg/animal-daily) + tylosin (90 mg/animal-daily); 3) monensin + L. salivarius L28 (106 CFU/animal-daily); 4) tylosin; and 5) L. salivarius. Animals were fed (steam-flaked corn-based finishing diet) once-daily (clean-bunk management). Feeding behavior (24 h; 5 min intervals) was measured as time spent in activities. In addition, one steer/pen was individually assessed. The Glimmix procedures of SAS were used for statistical analyses (fixed effect = treatment; random effect = block). Feed additives did not affect time spent eating (163 min/d; P = 0.42); ruminating (71 min/d; P = 0.82); chewing (234 min/d; P = 0.21); drinking (18 min/d; P = 0.59); ruminating/kg of DM (9 min/d; P = 0.75); chewing/kg of DM (30 min/d; P = 0.40); resting (1085 min/d; P = 0.25); or other activities (102 min/d; P = 0.32). The difference between feeding behavior pen average and the value from the single animal marked within the same pen was different from zero for rumination (P ≤ 0.04), eating (P = 0.03), and other activities (P = 0.04), while not different from zero for chewing (P ≥ 0.21), drinking (P ≥ 0.13; except for one treatment P &lt; 0.01), and resting (P ≥ 0.12; tendency exhibited by one treatment P &lt; 0.09). Feed additives seem to not affect feeding behavior half-way-through the finishing phase. One animal within a 4-animal/pen unit did not represent the pen average feeding behavior.

Abstract This study evaluated the effect of an algae-clay-complex-based feed additive (ACC, Olmix Group, Brehan, France) and diet formulation regimen on growth performance and carcass characteristics of finishing pigs. A total of 1,188 pigs (PIC 337×1050, initially 49.5 kg) were used in a 90-day study. There were 27 pigs per pen and 11 replications per treatment. Dietary treatments were arranged in a 2×2 factorial with main effects of ACC (none or 0.10% until 100 kg body weight and 0.05% thereafter) and dietary formulation regimen (High vs Low). High diets were formulated to maximize growth with added fat and no dried distillers grains with solubles (DDGS). Low diets were formulated to contain approximately 150 kcal/kg less net energy (NE), 30% DDGS, no added fat, and were formulated 0.10% below the standardized ileal digestible (SID) lys requirement based on the SID Lys:NE ratio as estimated in the High diets. Data were analyzed using the GLIMMIX procedure of SAS. There were no ACC × formulation interactions (P &gt;0.220) for growth or carcass characteristics. Overall, ADG was greater (P=0.027) for pigs fed diets with ACC compared with those fed diets without ACC with no change in ADFI or G:F (P &gt;0.180). This was a result of late finishing (d 56 to 90) ADG and G:F increase (P&lt; 0.019) for pigs fed diets with ACC compared with those fed no ACC. Also, pigs fed High diets had improved (P&lt; 0.047) ADG, ADFI, G:F and final body weight compared to pigs fed Low diets. For carcass characteristics, pigs fed High diets tended to have greater (P=0.067) loin depth and had greater (P&lt; 0.001) carcass weight than pigs fed low diets with no evidence for differences between the control and pigs fed ACC (P &gt;0.05). The addition of ACC resulted in improved ADG and G:F in late finishing, but did not affect carcass characteristics.

Abstract The objectives were to determine if the augmented growth performance of gilts administered anti-gonadotropin-releasing factor (GnRF) would require additional lysine and if anti-GnRF-treated gilts would require additional lysine to enhance carcass characteristics. The study treatments were arranged as a 2×3 factorial: control vs anti-GnRF (day 7 and 84; day 0 = 11 wk of age) and lysine at 100, 110, or 120% of requirement of the control gilts. Pen (n = 60) was the experimental unit (10 pens per treatment with 18 or 19 pigs per pen). There was no lysine × anti-GnRF interactions (P ≥ 0.2). Immunized gilts grew 3.7% faster and consumed 3.9% more feed with similar gain:feed from day 0 to market with increases occurring after the administration of the 2nd anti-GnRF dose. Immunized gilts weighed 3.4-kg more at marketing. The timing of marketing (4- or 6-week post 2nd dose) influenced the effects of anti-GnRF. Hot carcass weight, loin depth, and belly weight and thickness in anti-GnRF treated gilts were similar to control gilts at 4-weeks post 2nd dose but were greater in anti-GnRF vs. control (P ≤ 0.05) when harvested 6-weeks post 2nd dose. Backfat was greater, and lean was less, in immunized gilts vs. controls regardless of time to harvest. In conclusion, gilts immunized against GnRF had heavier carcass weights and required no additional lysine compared to controls.

Abstract A total of 2,430 pigs (PIC 337 × 1050; Hendersonville, TN; initially 30.1 kg) were used in a 113-d growth trial to determine the effects of increasing dietary Zn on growth performance and carcass characteristics of finishing pigs raised under commercial conditions. Pens of pigs were assigned to be fed one of five dietary treatments in a randomized complete block design. Treatments consisted of 50, 87.5, 125, 162.5, or 200 mg/kg added Zn from Zn hydroxychloride (IntelliBond Z, Micronutrients, Indianapolis, IN). Two identical barns were used for a total of 18 pens per treatment with 27 pigs per pen. Experimental diets were fed in five phases and contained a vitamin-trace mineral premix without added Zn. Pens of pigs were weighed approximately every 2 wk to calculate average daily gain (ADG), average daily feed intake (ADFI), and gain-to-feed ratio (G:F). At the end of the experimental period, pigs were tattooed with a pen identification number and transported to a packing plant to measure hot carcass weight (HCW), backfat, loin depth, and calculated lean percentage. Data were analyzed block nested within barn as a random effect and pen as the experimental unit. From days 0 to 42, pigs fed diets with increasing added Zn had lower (linear, P = 0.043) ADFI and a tendency (P = 0.092) for lower ADG. From days 42 to 113, increasing added Zn resulted in a quadratic response (P = 0.042) for ADFI and a tendency (linear, P = 0.056) for improved G:F. Overall (days 0 to 113), there were tendencies for quadratic responses for ADFI (P = 0.073) and G:F (P = 0.059), with the greatest G:F observed when 125 mg/kg of Zn was fed. Increasing added Zn resulted in a linear increase (P &lt; 0.001) in daily Zn intake. There were no differences (P &gt; 0.10) in overall ADG, final body weight, HCW, backfat, loin depth, lean percentage, mortality, and removal rate. In conclusion, there were no improvements in ADG when feeding beyond 50 mg/kg added Zn; however, providing 125 mg/kg added Zn resulted in the greatest G:F.

Abstract Previous research has indicated that starch gelatinization during the pelleting process is greater for Enogen® Feed corn compared to conventional yellow dent corn. Increasing starch gelatinization in the pellet increases the starch digestibility in the pig, which potentially leads to increased growth rate. Therefore, the objective of this study was to determine the effects of feeding Enogen Feed corn in meal or pellet form on finishing pig growth performance and carcass characteristics. A total of 288 pigs (53.0 ± 0.5 kg) were used with 8 pigs/pen and 9 pens/treatment in a 72-d study. Treatments were arranged in a 2×2 factorial with main effects of corn source (Enogen Feed corn or conventional yellow dent corn) and diet form (meal or pellet). Main effects of corn source and diet form as well as their interactions were tested. Pelleting parameters were established with a target conditioner temperature of 82.2°C and corn moisture of 13 to 14%. When pelleting the diets, the conditioning temperature for conventional yellow dent corn averaged 68.4°C and Enogen Feed corn averaged 67.7°C. The hot pellet temperature for conventional yellow dent corn averaged 75.1°C and 75.8°C for Enogen feed corn. For overall performance (d 0 to 72), no interactions between corn source and diet form were observed (P &gt; 0.05). There was a tendency (P &lt; 0.10) for slightly improved average daily gain (ADG) and gain:feed ratio (G:F) for pigs fed conventional yellow dent corn compared to those fed Enogen Feed corn. Pigs fed pelleted diets had increased (P &lt; 0.001) ADG, G:F, and hot carcass weight compared to pigs fed meal diets. In summary, feeding pelleted diets to finishing pigs increased ADG and G:F compared to those fed meal-based diets. There were no major differences observed between corn sources or interactions between corn source and diet form on growth performance.
