High-moisture barley (HMB) was ensiled or treated with 1% (wt/wt) liquid sulfur dioxide (SO2). Forty-five weanling pigs were allocated to five dietary treatments for 28 d. Diets consisted of: (1) dry barley, diet mixed every 28 d; (2) ensiled HMB, diet mixed daily; (3) SO2-treated HMB, diet mixed every 28 d; (4) SO2-treated HMB, diet mixed daily; (5) SO2-treated HMB, diet mixed daily and supplemented with thiamin. All diets contained 47% barley on a dry matter (DM) basis. Pigs fed diets 2 and 4 continued on test to 85 kg; diets formulated after 28 d contained 75% barley (DM basis). Feed intake, growth rate and feed:gain ratio were not influenced (P < 0.05) by treatment during the 28-d initial trial. For pigs fed SO2-treated HMB to 85 kg, feed intake and average daily gain were reduced by 9.8 and 9.0%, respectively. SO2 treatment effectively preserved high-moisture barley for 18 d at 16 °C; however, 61% of the dietary thiamin was destroyed by 7 d after diet mixing. Pigs fed diet 4 were thiamin depleted at slaughter; with a 38.5% higher erythrocyte thamin pyrophosphate effect, an 83% incidence of cardiac hypertrophy and thiamin levels in meat reduced to 7.6% of that present in the meat of pigs fed untreated HMB. Destruction of dietary thiamin appears to have been the primary factor responsible for reduced animal performance. Reduced ration palatability and toxicological effects on the digestive tract due to 75% SO2 treated grain in the diet (DM basis) may have also contributed to the reduced performance of growing-finishing pigs.

Two experiments were conducted to determine the influence of feeding sulfur dioxide (SO2)-treated high-moisture barley (HMB) on the performance of lactating dairy cows and feedlot cattle. High-moisture barley was ensiled or treated with 1% (wt/wt) liquid SO2. In exp. 1, 36 lactating Holstein cows were assigned to three treatments for a 6-wk trial. Diets contained 35% rolled barley on a dry matter (DM) basis and differed only in the type of barley fed: dry barley, ensiled HMB or SO2-treated HMB. While no differences (P > 0.05) were observed in DM intake, milk yield, milk composition, milk taste or odour, cows fed SO2-treated HMB tended to have lower milk yield (21.7 kg d−1) than those fed ensiled (22.6 kg d−1) or dry barley (24.6 kg d−1). In experiment 2, 64 steers were allotted to four dietary treatments: (1) dry barley, (2) ensiled HMB, (3) SO2-treated HMB, and (4) SO2-treated HMB plus sodium bicarbonate. All diets contained 85% barley (DM) and were supplemented with thiamin (5.5 mg kg−1 DM). The results of the feedlot trial were confounded by the feeding of spoiled SO2-treated HMB, primarily between days 29 and 57 of the 96-d trial, at approximately 40% of the diet DM. During the period that spoiled SO2-treated grain was being fed, four steers (two from each treatment) developed polioencephalomalacia. Steers fed SO2-treated HMB (diets 3 and 4), had 10.1% lower DM intake (P < 0.01), 31% lower average daily gain and required 32% more DM per kilogram of gain than steers fed diets 1 or 2 (P < 0.001). Feeding SO2-treated HMB to either dairy or feedlot cattle cannot be recommended at the present time. Key words: Sulfur dioxide, preservative, barley, cattle (dairy, beef)

AbstractThe objective was to evaluate the effect of dietary Bacillus altitudinis spore supplementation during day (D)0–28 post-weaning (PW) and/or D29–56 PW compared with antibiotic and zinc oxide (AB + ZnO) supplementation on pig growth and gut microbiota. Eighty piglets were selected at weaning and randomly assigned to one of five dietary treatments: (1) negative control (Con/Con); (2) probiotic spores from D29–56 PW (Con/Pro); (3) probiotic spores from D0–28 PW (Pro/Con); (4) probiotic spores from D0–56 PW (Pro/Pro) and (5) AB + ZnO from D0–28 PW. Overall, compared with the AB + ZnO group, the Pro/Con group had lower body weight, average daily gain and feed intake and the Pro/Pro group tended to have lower daily gain and feed intake. However, none of these parameters differed between any of the probiotic-treated groups and the Con/Con group. Overall, AB + ZnO-supplemented pigs had higher Bacteroidaceae and Prevotellaceae and lower Lactobacillaceae and Spirochaetaceae abundance compared to the Con/Con group, which may help to explain improvements in growth between D15–28 PW. The butyrate-producing genera Agathobacter, Faecalibacterium and Roseburia were more abundant in the Pro/Con group compared with the Con/Con group on D35 PW. Thus, whilst supplementation with B. altitudinis did not enhance pig growth performance, it did have a subtle, albeit potentially beneficial, impact on the intestinal microbiota.

Abstract A total of 2,164 pigs [DNA610 x DNA241; initially 100.7 ± 2.14 kg body weight (BW)] were used in a 54.1 ± 3.85-day study to determine dietary strategies to limit average daily gain (ADG) in late finishing pigs raised in a commercial environment. Mixed-sex pens (20.0 ± 0.85 pigs/pen) balanced by initial BW and gender ratio were randomly assigned to 1 of 4 dietary treatments fed ad libitum with 27 replications each: (1) Nutritionally replete corn soybean-meal control (CTRL), (2) Treatment 1 with 21% reduced lysine and other amino acids (AAR), (3) Corn/vitamin/mineral diet (CVM), and (4) Treatment 3 fed for 21 days then switched to CTRL. Data were analyzed as a randomized complete block design using a linear mixed model. Relative to CTRL, feeding AAR or CVM for 21 days reduced ADG (P &lt; 0.001), average daily feed intake (ADFI; P = 0.005), and gain-to-feed (G:F, P &lt; 0.001). Over 55-days, AAR and CVM diets reduced (P &lt; 0.001) cumulative ADG, ADFI, G:F, and final BW compared to CTRL. Transitioning to CTRL diet from CVM diet after 21-days increased ADG (P &lt; 0.001) and improved G:F (P &lt; 0.001) from day 21 to marketing compared to 55-day CTRL, AAR, and CVM; nevertheless, the compensatory CTRL period was insufficient for the 21-day CVM fed pigs to fully compensate resulting in reduced cumulative BW, ADG (P &lt; 0.001) and poorer G:F (P &lt; 0.001) than the 55-day CTRL. All holding strategies decreased (P &lt; 0.001) carcass yield, hot carcass weight (HCW), and loin depth compared to CTRL. Utilizing a CVM diet for 21 or 55 days increased (P &lt; 0.001) backfat compared to CTRL or AAR. In summary, utilizing lysine deficient or corn/vitamin/mineral diets can limit ADG along with poorer G:F. Transitioning to a non-holding diet after feeding a corn/vitamin/mineral diet for 21-days resulted in compensatory gain, but reductions in growth performance and carcass traits remained evident.

Abstract Our objective was to evaluate the effects of different vitamin concentrations on growth performance of wean-to-finish pigs under commercial conditions. A total of 900 barrows and gilts (PIC337×Camborough; initially 5.34±0.13 kg) were used in a 136-d growth trial with 25 pigs per pen and 12 pens per treatment in a randomized complete block design. Experimental diets were fed in 3 phases during nursery (5-6, 6-13, and 13-26 kg) and 5 phases during grow-finish (26-44, 44-65, 65-87, 87-108, and 108-128 kg). Dietary treatments consisted of: 1) NRC: vitamin concentrations following NRC (2012) recommendations; 2) PIC: vitamin concentrations following PIC (2016) recommendations; 3) Low-PIC: vitamin concentrations that ranged from 0 to 91% of PIC recommendations. Data were analyzed using the GLIMMIX procedure of SAS with pen as the experimental unit. During the nursery period, pigs fed PIC and Low-PIC diets had greater (P&lt; 0.05) average daily feed intake (ADFI) compared to pigs fed NRC diets. There was no evidence (P &gt;0.10) for differences in average daily gain (ADG) and feed efficiency (G:F). During the grow-finish period, there was no evidence (P &gt;0.10) for differences in growth performance. During the overall wean-to-finish period, pigs fed PIC diets had lower (P&lt; 0.05) ADG and final body weight compared to pigs fed NRC and Low-PIC diets. There was no evidence (P &gt;0.10) for differences in ADFI or G:F. Pigs fed PIC diets had the greatest serum vitamin D3 at the end of nursery and finish periods (P&lt; 0.05) and the greatest serum Vitamin E at the end of nursery period (P&lt; 0.05). In summary, pigs fed PIC and Low-PIC diets had greater nursery feed intake and serum vitamin E and D3 concentrations compared to pigs fed NRC diets. Data from this study have demonstrated that pigs fed diets with reduced vitamin concentrations compared to PIC (2016) recommendations had improved wean-to-finish growth rate.

Standardized Ileal Digestible Lysine

Abstract Our objective was to determine the effects of feeding different neutral detergent fiber (NDF) and standardized ileal digestible (SID) lysine (Lys) levels on performance of growing-finishing pigs from 30- to 130-kg. A total of 2,016 barrows and gilts (PIC 280×Camborough, initial BW of 29.6±0.53 kg) were allotted to a randomized complete block design with a 2×2 factorial arrangement. Dietary treatments (Table 1) consisted with two NDF levels (13% or 20%) and two SID Lys curves (PIC2008 or PIC2016). There were 21 mixed-sex pigs per pen, and 24 pens per treatment. The experiment diets were fed in 3 phases. Wheat, wheat by-products, peas, and canola oil were used with NRC (2012) loading values to achieve treatments, and all diets were formulated to be iso-caloric (2,420 kcal NE/kg). Experimental data were analyzed using generalized linear mixed models with pen as the experimental unit. Increasing NDF level resulted in a reduction (P&lt; 0.05) in average daily gain (ADG), average daily feed intake, hot carcass weight, carcass yield, carcass ADG, and backfat depth (Table 2), and tended to decrease percentage of removals and mortality (P=0.10). Pigs fed PIC2016 Lys curve had greater ADG and carcass ADG as compared to those fed PIC2008 Lys curve (P&lt; 0.05). There were NDF×Lys interactions (P&lt; 0.10) for ADG, gain to feed ratio (G:F), carcass ADG, and carcass G:F. These response criteria were improved for pigs fed PIC2016 Lys curve compared to those fed PIC2008 Lys curve when NDF level was 13%; while no evidence of differences was observed at 20% NDF. Results indicate that increasing NDF level from 13 to 20% deteriorate performance of 30- to 130- kg pigs; and the improved growth performance of pigs fed PIC2016 Lys curve as compared to those fed PIC2008 Lys curve was only observed when lower NDF level was presented.

Abstract Based on results of a recent meta-analysis, we hypothesized that increased dietary Val, Ile, or Trp could correct possible amino acid interactions because of excess Leu in diets containing high levels of corn protein, namely dried distiller’s grains with solubles (DDGS). A total of 1,200 pigs (PIC TR4 × (Fast LW × PIC L02); initially 33.6 ± 0.6 kg) were used in a 103-d study. The 6 dietary treatments were corn–soybean meal (SBM)-DDGS-based as follows: (1) high SBM and low level of l-Lys HCl (HSBM), (2) high l-Lys HCl and moderate Ile, Val, Trp (AA above NRC 2012 estimates; NC), (3) moderate l-Lys HCl and high Ile, Val, and Trp (PC), and PC with either increased (4) L-Val (PC+Val), (5) L-Ile (PC+Ile), or (6) L-Trp (PC+Trp). Pigs fed the NC diet were predicted to have the poorest average daily gain (ADG), the PC diet to be intermediate, and pigs fed the HSBM, PC+Val, PC+Ile, and PC+Trp have the same and highest predicted ADG. In the grower period (34 to 90 kg), ADG was greater (Ρ &lt; 0.05) for the pigs fed HSBM and PC+Val diets than the NC with pigs fed other diets intermediate. Pigs fed HSBM were more (Ρ &lt; 0.05) efficient (G:F) than the NC and PC with pigs fed other diets intermediate. In the finisher period (90 to 136 kg), ADG was greater (Ρ &lt; 0.05) for pigs fed PC+Ile than that of the NC with pigs fed other diets intermediate. Pigs fed PC+Val had greater (Ρ &lt; 0.05) average daily feed intake (ADFI) than the NC with pigs fed other diets intermediate. However, PC+Ile pigs were more (Ρ &lt; 0.05) efficient than PC+Val with pigs fed other diets intermediate. Overall, ADG was greater (Ρ &lt; 0.05) for pigs fed HSBM, PC+Val, and PC+Ile diets than the NC with pigs fed other diets intermediate. Pigs fed the PC+Val diet had greater (Ρ &lt; 0.05) ADFI than the NC with pigs fed other diets intermediate. No differences were detected between treatments for overall G:F or other carcass characteristics. In conclusion, increasing Val or Ile in high l-Lys-HCl-DDGS-based diets improved growth performance compared with pigs fed diets containing high levels of l-Lys HCl without added Val and Ile. These results present evidence that the recently developed meta-analysis can predict the relative differences in overall ADG for pigs fed the NC, PC, PC+Val, and PC+Ile diets; however, the predicted G:F was less accurate. The data demonstrate that the negative effects of high Leu concentrations in corn-DDGS-based diets can be reversed by increasing the ratios of Val and Ile relative to Lys.

Sixty-six Dorset Horn lambs weaned at 8 wk of age were fed dry (88% DM) or high-moisture (73% DM), reconstituted, acid-preserved barley-based diets either whole or as 5-mm or 9-mm pellets. Lambs fed high-moisture or dry barley performed similarly in terms of feed intake, average daily gain, feed conversion ratios (DM basis) and digestibility of protein. Digestibility of organic matter was slightly higher (P < 0.05) for dry than moist barley. Whole barley resulted in faster (P < 0.05) growth rates than either 5-mm or 9-mm pellets, 276, 221 and 227 g/day, respectively. The corresponding feed convetsion ratios were 3.94, 4.24 qnd 4.31. Pelleting had no significant (P < 0.05) effect on feed intake or the digestibility of organic matter or protein.

This study was conducted to evaluate the effect of choline chloride alone and in combination with propylene glycol on the growth performance, meat quality and backfat in finishing pigs. A total of 90 crossbred ((Landrace× Yorkshire)× Duroc) pigs with an average initial body weight (BW) of 75.15± 1.94 kg were randomly distributed by BW and sex. This 8-week experiment consisted of 3 dietary treatments with 6 replications per treatment and 5 pigs per pen. The experiment included 3 treatments: CON, basic diet; TRT1, basic diet+0.05% choline chloride; TRT2, basic diet+0.05% biocholine P (chloride chloride and propylene glycol). Body weight was statistically higher (P less than 0.05) in pigs fed TRT2 diet than the CON diet in week 8. During 4 to 8 weeks and overall, the average daily gain (ADG) was significant higher (P less than 0.05) in the pigs fed TRT2 diet than the CON diet. Digestibility of nitrogen was significantly increased (P less than 0.05) at week 4 and week 8, back fat was higher (P less than 0.05) in week 6 and week 8 in pigs fed TRT2 diet than the CON diet. In conclusion, dietary TRT2 can increase the BW, ADG, nitrogen, and backfat in finishing pigs.
