The objective of this experiment was to determine the effects of feeding graded levels of Linpro (a 50:50 combination of extruded full-fat flax seed and peas) on pig performance and carcass traits, particularly the fatty acid composition of backfat. Eighty crossbred pigs (Camborough 15 Line female × Canabred sire, Pig Improvement Canada Ltd., Airdrie, AB) weighing an average of 22.7 ± 2.2 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a 5 × 2 factorial arrangement (treatment × sex). The experimental diets were based on barley and soybean meal and contained 0, 7.5, 15, 22.5 or 30% Linpro during the growing period (22.7–69.7 kg) and 0, 6, 12, 18 or 24% Linpro during the finishing period (69.7–111.1 kg). Digestibility coefficients for dry matter were not significantly affected by incorporation of Linpro in the diet. Digestibility coefficients for crude protein (P = 0.01) and gross energy (P = 0.04) exhibited a cubic effect due to Linpro incorporation with the highest digestibility coefficients observed for pigs fed 7.5% Linpro. Over the entire experimental period (22.7–111.1 kg), daily gain was affected both linearly (P = 0.02) and quadratically (P = 0.04) by Linpro inclusion. The most rapid gains were obtained by pigs fed 7.5% Linpro (6% in finisher), while pigs fed 30% Linpro (24% in finisher) gained weight the slowest. Feed intake was not significantly affected by Linpro inclusion, while feed conversion exhibited a quadratic effect (P = 0.02) with pigs fed the highest and lowest levels o f Linpro showing the poorest feed conversion. Linpro inclusion, had no significant effects on carcass traits including slaughter weight, carcass weight, dressing percent, carcass value index, lean yield, loin fat or loin lean. Inclusion of 30% Linpro (24% in finisher) significantly (P < 0.05) increased the levels of linolenic acid in backfat and this increase could provide significant health benefits for consumers of pork. Linpro would appear to be an acceptable alternative to soybean meal as a protein supplement for use in growing-finishing swine diets and can be incorporated at levels as high as 22.5% in the grower period and 18% in the finisher period without detrimental affects on pig performance.

This study was conducted to determine the performance and carcass characteristics of growing-finishing pigs fed diets containing graded levels of canaryseed. Sixty-four crossbred pigs (Pig Improvement Canada Ltd) weighing 34.4 ± 2.8 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a factorial (5 treatments × 2 sexes) arrangement. A barley and soybean meal diet served as the control. The remaining pigs were fed diets in which approximately 25, 50, 75 or 100% of the barley was replaced by canaryseed (cv. Elias). There was a linear (P = 0.01) decrease in dry matter digestibility with increasing level of canaryseed. In contrast, crude protein digestibility showed a linear increase (P = 0.01) with increasing level of canaryseed. Gross energy digestibility of the diets did not differ (P > 0.05). Over the entire experimental period (34.4 to 107.8 kg), there was a quadratic (P = 0.01) response for weight gain. The 25% canaryseed diet supported the highest growth rate and pigs fed the 100% canaryseed diet had the lowest gain. Feed intake and feed conversion were unaffected (P > 0.05) by level of canaryseed. There were no differences (P > 0.05) in carcass weight, carcass value index, estimated lean yield, loin fat depth or loin lean depth as a result of canaryseed inclusion. However, there was a quadratic (P = 0.02) response for dressing percentage with increasing level of canaryseed. The overall results of this experiment provide a favorable indication that canaryseed can be successfully fed to growing-finishing pigs without dramatically affecting pig performance or carcass characteristics. Therefore, in the future, the swine industry may provide an alternative to the caged bird market as an outlet for growers of canary seed to market their product.

Pig Performance

This experiment was conducted to determine the effect of graded levels of number 1 wheat screenings on performance, nutrient digestibility and carcass traits when fed to growing-finishing pigs. Forty crossbred pigs (Camborough 15 Line female × Canabred sire) weighing an average of 19.7 ± 2.8 kg were assigned to one of five dietary treatments in a 5 × 2 factorial design experiment. The main effects tested included level of wheat screenings and sex of pig (barrows and gilts). The levels of inclusion were 0, 18, 36, 54 and 72% in the grower diet and 0, 20.5, 41, 61.5 and 82% in the finisher diet. Screenings were added largely at the expense of barley. A botanical analysis was preformed and it indicated that the screenings contained approximately 88.5% whole or cracked wheat with the most prevalent weed seeds being wild buckwheat (6.7%), canola seed (2.8%) and cleavers (0.96%). There was a linear (P = 0.001) increase in the digestibility of dry matter, crude protein and gross energy with increased incorporation of wheat screenings in the diet. Over the entire experimental period (19.7–105.1 kg), there was no change in growth rate due to feeding wheat screenings, but feed intake declined in a linear (P = 0.044) fashion while feed conversion improved linearly (P = 0.014) as the inclusion level of screenings increased. There were no sex effects on pig performance. Dietary inclusion of wheat screenings had no significant effects on any carcass traits including dressing percent, carcass value index, lean yield, loin fat or loin lean. The carcass value index for gilts was higher than that of barrows (P = 0.038). The overall results of this experiment indicate that number 1 wheat screenings can be successfully uti lized as an energy source for use in growing-finishing diets and can be fed at levels as high as 72% for growing pigs and 82% for finishing pigs with no negative effects on pig performance or carcass quality. However, should the level of weed seeds increase or the type of weed seeds contaminating the screenings change appreciably from those reported here, then it may be necessary to reduce the incorporation level of screenings in the diet.

Abstract The effects of feeding diets based on soybean meal, low phytate hulless barley (Lphybarley) and low phytate pea (Lphypea) with inorganic phosphorus (iP) reduced by 50 or 100% to broiler chickens on performance, P digestibility and bone characteristics were investigated. Two hundred and ten day-old (Ross 308 strain) broiler chicks (5 birds per cage; 6 cages per diet) were randomly allocated to 7 dietary treatments for a 21-day study. Diets were formulated based on soybean meal-normal phytate hulless barley (SBM-normbarley) with added inorganic P (iP) to meet NRC (1994) P requirements (SBM-normbarley100) or with 50% less iP (SBM-normbarley50), soybean meal-Lphybarley-Lphypea with added iP (Lphybarley-Lphypea100) or iP reduced by 50% (Lphybarley-Lphypea50) or 100% (Lphybarley-Lphypea0), and soybean meal-normbarleynormal phytate pea (normpea) with added iP (normbarley-normpea100) or iP reduced by 50% (normbarley-normpea50). Birds fed the Lphybarley-Lphypea0 diet had the lowest (P<0.001) ADG compared with those fed the other diets. Reducing iP by 50% led to a reduction (P<0.05) in ADG for birds fed the SBM-normbarley- and normbarley-normpea-based diets but not in the Lphybarley- Lphypea-based diet. Reducing iP by 50% led to a reduction (P<0.05) in ADFI in birds fed the SBM-normbarley-based diet and normbarley-normpea-based diet compared with those fed adequate iP. Feed conversion ratio was not affected by diet throughout the experimental period (P>0.10). Reducing iP content reduced P retention in the SBM-normbarley-based diet but not in the normbarley-normpea-based diet but tibia ash and length were reduced in birds fed both diets (P<0.05). Reducing dietary iP content linearly increased (P < 0.05) P retention and linearly decreased (P<0.05) tibia ash and length in the Lphypea-Lphybarley-based diets. In conclusion, feeding a low phytate hulless barley-low phytate pea based diet with iP reduced by 50% supported similar performance as control and increased P retention, suggesting that utilizing a combination of low phytate ingredients can reduce the need for supplemental iP with significant cost and environmental implication.

The effect of partial and total replacement of soybean meal (SBM) with extruded chickpeas (Cicer arietinum L.) and partial replacement of SBM with raw chickpeas on pig growth and carcass characteristics was determined in a 17 week experiment. Sixty growing-finishing pigs were allocated to five dietary treatments: CKP0, ECKP100, ECKP200, ECKP300 and CKP100 of 12 animals each, and received a diet ad libitum. The diet for CKP0 treatment had no chickpeas (control), while those for treatments ECKP100, ECKP200 and ECKP300 included 100, 200 and 300 kg/t of extruded (at 120&deg;C for 20 s) chickpeas, respectively, and for treatment CKP100 it included 100 kg/t of raw chickpeas. Body weight (BW) gain linearly increased (P &lt; 0.05) and feed conversion ratio (FCR) linearly decreased (P &lt; 0.05) with the inclusion of increasing levels of extruded chickpeas during the growing period. However, in both the growing and finishing period, there were no differences between extruded chickpea inclusion treatments in final BW, BW gain, daily feed consumption (DFC), FCR, and carcass yield traits. Partial replacement of SBM with raw chickpeas negatively affected (P &lt; 0.05) BW gain and DFC during the finishing period. Extrusion offers a practical method for the heat processing of chickpeas for use in pig diets. Thus, extruded chickpeas can be used as an alternative protein source to SBM at inclusion levels up to 300 kg/t of diet. &nbsp; &nbsp;

Abstract A total of 860 finishing pigs (PIC C48/L42×327; initially 66.2 kg BW) were used in a 76-d experiment to evaluate the effects of removing corn DDGS from diets at increasing intervals before harvest. Diets contained 40% DDGS prior to the experiment, 0 or 35% DDGS during the experiment from approximately 66 to 82 kg and 0 or 30% DDGS until the completion of the trial. Pen served as the experimental unit, and there were 7 replicate pens/treatment with 23 to 25 pigs/pen. Pens were blocked by BW and allotted to 1 of 5 dietary treatments, differentiated by the number of days prior to slaughter that diets containing DDGS were withdrawn and replaced with corn-soybean meal-based diets. Withdrawal times were 76, 42, 27, 15, or 0 d (no withdrawal) before harvest. Linear and quadratic response to withdrawal time was evaluated using PROC GLIMMIX. For the overall period (d -76 to 0), as time of DDGS withdrawal increased, ADG and final BW also increased (linear, P < 0.018) and G:F improved (quadratic, P = 0.019). Average daily feed intake quadratically decreased (P = 0.030) with increasing withdrawal time. There was a linear increase (P = 0.010) in HCW, with a marginally significant increase in carcass yield (linear, P = 0.094) with increasing DDGS withdrawal time. Loin depth and lean percentage did not demonstrate any evidence for treatment differences (P > 0.132). Backfat was linearly increased (P = 0.030) with increasing DDGS withdrawal time. Lastly, iodine value (IV) of belly fat was increased (linear, P = 0.001) with increased feeding duration of DDGS. In conclusion, removing pigs from diets containing DDGS for longer periods before slaughter increased ADG and improved G:F, resulting in increased HCW. Belly fat IV was decreased as the length of DDGS withdrawal increased, with the highest IV resulting from pigs that consumed DDGS for the entire experimental period.

The objective of this study was to compare a high-fat oat recently developed at the University of Saskatchewan with regular oat as energy sources for use in diets fed to growing-finishing pigs. Seventy crossbred pigs (Pig Improvement Canada Ltd, Acme, AB) weighing an average of 27.5 ± 2.6 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a factorial design experiment. The main effects tested included oat type (normal and high fat), level of oat inclusion (0, 25 and 50%) and sex of pig (barrows and gilts). Digestibility coefficients for dry matter (P = 0.002), crude protein (P = 0.001) and gross energy (P = 0.004) were significantly higher for pigs fed high-fat oat compared with normal oat. Pigs fed the high-fat oat also gained weight significantly faster (P = 0.01) and with increased efficiency (P = 0.01) compared with pigs fed diets containing normal oat. Oat level did not affect pig performance (P > 0.05). Neither type of oat nor level of inclusion had any significant (P > 0.05) effects on any carcass trait including dressing percent, carcass value index, lean yield, loin fat or loin lean. In conclusion, feeding diets containing a recently developed high-fat oat to pigs improved growth rate and efficiency of feed conversion compared with feeding diets containing normal-fat oat. Nutrient digestibility also improved with no negative effects on carcass quality. High-fat oat is an attractive alternative to normal oat as an energy source for growing-finishing pigs and can be fed at higher levels than are currently recommended for normal oat without hindering pig performance.

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.

Abstract Dried distiller grains with solubles (DDGS) is a popular protein source in grow-finish swine diets to replace soybean meal. An experiment was conducted at the South Dakota State University commercial swine research facility to determine the effect of standardized ileal digestible (SID) Trp:Lys ratio in grow-finish swine diets containing 40% DDGS compared to a standard corn-soybean meal diet. A total of 1,170 pigs (38.6 ± 0.2 kg initial BW) were utilized in a 98-d trial (9 pens per treatment). Pens of pigs were randomly allotted to 1 of 4 DDGS dietary treatments providing SID Trp at 15, 18, 21, and 24% of Lys or a corn-soybean meal diet (18%). Diets were isocaloric, with lysine at 100% of the requirement. From d 0 to 82, increasing Trp:Lys ratio in DDGS diets improved (P &lt; 0.01) BW, ADG, and ADFI with no effect on F:G. Pigs fed the corn-soybean meal diet had greater (P &lt; 0.01) BW, ADG, ADFI, and F:G compared to the DDGS diets with the exception of the ADFI of the 24% Trp:Lys treatment. From d 82 to 98, increasing SID Trp:Lys in DDGS diets had no effect on performance. Overall (d 0 to 98), increasing SID Trp:Lys in DDGS diets increased (P &lt; 0.02) final BW and ADG, but pigs failed to perform to the same degree as the corn-soybean meal diet. Increasing SID Trp:Lys in DDGS diets resulted in an increase in hot carcass weight (P &lt; 0.01); however, diets containing DDGS had decreased (P &lt; 0.02) hot carcass weight, dressing percentage, percent lean, and loin depth compared to pigs fed the corn-soybean meal diet. These results indicate that increasing the SID Trp:Lys in diets containing 40% DDGS improved performance in early grow-finish phases with no effect in late finishing, but performance was inferior to standard corn-soybean meal diets.

The present study was to evaluate the impact of rapeseed meal (RSM), canola meal (CM), and their mixture substitute for soybean meal on performance of lactating sows and their offspring. In total, 16 Yorkshire×Landrace sows with initial BW 258.87±5.36 kg were used in this trial. The experimental period lasted 30 days. The sows were allotted to one of four dietary treatments (4 sows per treatment): 1) corn-soybean meal (SBM) basal diets; 2) basal diets containing 8% RSM; 3) basal diets containing 8% CM; 4) basal diets containing RSM (4%) and CM (4%) mixture (RSCM). Sows fed with RSM and RSCM diets had a higher (P less than 0.05) body weight loss than sows fed SBM diet. The parity, litter number, piglet survival rate, weaning pig number, backfat, ADFI and estrus interval were not influenced by dietary treatments (P greater than 0.05). The ADG of piglets from sows fed SBM was higher (P less than 0.05) than sows fed RSM at 1 week. After farrowing, the apparent total tract digestibility (ATTD) of dry matter in sows fed with SBM diet was higher (P less than 0.05) than the RSCM group. The ATTD of energy in SBM and CM treatments was higher (P less than 0.05) than that in RSM and RSCM treatments. On the weaning day, the ATTD of nitrogen and energy in SBM treatment was highest (P less than 0.05) than other treatments. In conclusion, inclusion of 8% rapeseed meal, canola meal, and their mixture substitute for soybean meal had negative effects on reproductive performance of lactating sows and their offspring.

A total of 150 crossbred pigs [(Duroc × Yorkshire) × Landrace; body weight (BW) = 5.74 ± 1.15 kg; weaned at day 21 after birth] were assigned to one of five dietary treatments (six pens per treatment and five pigs per pen) by BW and sex (two barrows and three gilts) for a 6 wk experiment. The pen was considered the experimental unit in the statistical model. Treatments were corn–soybean meal diets supplemented with 0.0033% tiamulin as well as 0%, 0.05%, 0.10%, or 0.20% fermented garlic (FG). The average daily gain, average daily feed intake (ADFI), and feed conversion ratio were linearly (p < 0.05) increased by FG inclusion during days 21–42 and days 0–42. Dietary supplementation of FG linearly increased (p < 0.05) the coefficient of apparent total tract digestibility of dry matter, nitrogen, and gross energy as well as blood immunoglobulin G concentration during week 6. The fecal ammonia (NH3), total mercaptan emissions, and Escherichia coli counts were linearly (p < 0.05) reduced by FG in the diet. Dietary supplementation of FG increased (p < 0.05) ADFI during days 21–42 and days 0–42 and reduced (p < 0.05) fecal NH3 emissions compared with pigs fed tiamulin. In conclusion, the results indicate that FG can enhance growth performance and digestibility, and reduce fecal E. coli counts as well as fecal gas emissions in weanling pigs.
