Feed intake, growth, plasma glucose and urea nitrogen concentration, and carcass traits of lambs fed isoenergetic amounts of canola meal, soybean meal, and fish meal with forage based diet

Sixty-four crossbred pigs (averaging 24 kg) were used to study the effects of dietary propionic acid (PA) on backfat measurements and fatty acid (FA) composition and on rate of gain and feed:gain ratio. Isonitrogenous and isoenergetic diets, based on either barley-soybean meal or barley-conola meal, contained either 0, 3, 6 or 9% PA. Inclusion of PA depressed feed intake in a linear manner, with daily gain being reduced when pigs received 6 or 9% PA. Feed:gain ratio did not differ significantly for PA treatments. Backfat thickness was significantly reduced by PA inclusion in the diet, while carcass grade was slightly improved. Inclusion of PA significantly increased levels of 15:0, 17:0 and 17:1 FA in the outer subcutaneous backfat layers with an accompanying decrease in 16:0 and 18:0 FA. Higher levels of odd-chain FA observed in the backfat of PA-supplemented pigs suggest that not all the propionic acid was metabolized; some is being incorporated directly into FA. Pigs fed diets containing 15.9–18.9% canola meal had reduced feed intake, lower daily gains, poorer feed:gain ratio, and reduced total backfat compared with those fed soybean meal diets. Pigs fed canola meal had higher backfat levels of 17:0 FA compared with those fed soybean meal. These results do not invalidate the current recommendation that 10% canola meal may be fed in diets of growing pigs.

Eighty crossbred pigs (28.7 ± 3.9 kg BW) were assigned to one of five dietary treatments in a factorial design experiment (sex × treatment). The control diet was formulated using barley and soybean meal, while four experimental diets were formulated with either toasted or non-toasted canola meal replacing either half or all of the soybean meal in the test diets. The total glucosinolate content of the non-toasted meal was more than 15-fold higher than the to asted meal (1.01 vs. 15.58 µmol g-1). The principal glucosinolates in the non-toasted meal were 3-butenyl (3.05 µmol g-1), 2-OH-3-butenyl (5.47 µmol g-1) and 4-OH-3-methylindoyl (4.68 µmol g-1). Digestibility coefficients for dry matter, crude protein, and gross energy were significantly (P < 0.05) lower for the toasted and non-toasted canola meal diets compared with the soybean meal diet. There were no significant differences (P > 0.05) in digestibility coefficients between the two canola meals. Digestibility coefficients were higher (P < 0.05) for pigs fed the diets in which canola meal supplied only 50% of the supplementary protein compared with diets in which 100% of the supplementary protein was supplied by canola meal. Pigs fed toasted canola meal had similar weight gain, feed intake and feed conversion (P > 0.05) as pigs fed soybean meal while pigs fed non-toasted canola meal had lower weight gain and feed intake (P < 0.05) than pigs fed soybean meal. Feed conversion was unaffected by dietary treatment (P > 0.05). There were no significant effects (P < 0.05) due to diet on any carcass trait. The overall results of this experiment indicate that omitting the desolventization/toasting procedure from the process involved in the production of canola meal did not result in an improvement in the performance of pigs fed diets containing canola meal.

Finishing Pigs

The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased (p < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced (p < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved (p < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher (p < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.

Lactating Sow

Abstract A total of 131 sows (Line 241; DNA, Columbus, NE) were used in a study to evaluate the effect of increasing soybean meal concentration in lactating sow diets on sow and litter performance. Sows were blocked by body weight (BW) within parity on day 112 of gestation and allotted to one of three treatments of increasing dietary soybean meal (25%, 30%, or 35% of the total diet). Diets were formulated to 1.05% standardized ileal digestible lysine (Lys) with L-Lys HCl decreasing as soybean meal increased. All other amino acids and nutrients were formulated to meet nutrient requirement recommendations. Diets were fed from day 112 of gestation until weaning (day 20 ± 2). Litters were cross-fostered up to 48 h after farrowing to equalize litter size. Increasing soybean meal concentration increased (linear, P = 0.017) sow BW loss and tended to increase (quadratic, P = 0.052) sow backfat loss from farrowing to weaning. Sow average daily feed intake (ADFI) from day 0 to 7 was similar (P > 0.10) across dietary treatments. However, from day 7 to 14, 14 to weaning, and overall, ADFI decreased (linear, P = 0.01) as soybean meal concentration increased. Despite the linear response in ADFI, the greatest decrease was observed as soybean meal concentration increased from 30% to 35% of the diet. There was no evidence for difference (P > 0.10) in wean-to-estrus interval, litter size, litter weight, or litter weight gain between dietary treatments. Sow serum urea nitrogen concentrations taken on day 14 of lactation increased (linear, P = 0.001) as soybean meal concentration increased. There was no difference (P > 0.05) for sow creatinine concentration, regardless of dietary treatment, suggesting that the increased urea nitrogen was a reflection of the increased dietary crude protein as opposed to increased protein catabolism. In summary, sow feed intake decreased and weight loss increased as soybean meal concentration of the diet increased, with the greatest decrease observed at 35% of the total diet. Although there were no differences in litter performance, it appeared that 35% soybean meal in the lactation diet negatively affected feed intake.

Stimulus Trial

Selection preferences of starter pigs (4–5 wk old) fed diets supplemented with soybean meal (SBM) and canola meal (CM) with or without added flavor were studied in four experiments. In exp. 1, starter pigs were offered a choice between a SBM control diet and one of four isonitrogenous, isoenergetic CM supplemented diets containing either 5, 10, 15 or 20% CM. From 5 to 9 wk of age, pigs consumed two and one-half to seven times more SBM control diet than diets containing 5–20% CM, respectively. In exp. 2, the influence of supplementary monosodium glutamate (0.15%), dextrose (10%) and corn oil (4 and 5%) on the consumption of diets in which CM replaced 50–100% of the protein supplied by SBM was studied. No significant differences in feed intake or pig performance were attributed to the addition of these additives to the CM diets. In experiments three and four, the effect of flavor additives (Pig Krave and Hy Sugr ADE) on the palatability of CM supplemented diets was determined. In exp. 3, feed intake of pigs fed diets containing 100% CM with added flavors was significantly greater than that of pigs fed the 100% CM nonflavored diets. In exp. 4, a single stimulus trial, pigs consumed more (P < 0.001) of the flavored CM diets than the nonflavored diets. The improved feed intake of flavored CM supplemented diets decreased as the level of dietary CM increased. Key words: Palatability, flavor additives, starter pigs, canola meal, soybean meal
