Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted to determine the nutritional value of corn- and sorghum-based dried distillers grains with solubles (DDGS). In Exp. 1, 120 finishing pigs (average initial weight of 244 lb) were used in a 19-d DE determination. The reference diet was 97% corn with vitamins, minerals, and amino acids added to meet or exceed all NRC suggested nutrient concentrations. Treatments were corn-based (Sioux River Ethanol, Hudson, SD and MGP Ingredients, Atchison, KS) and sorghum-based (US Energy Partners, Russell, KS and Western Plains Energy, Oakley, KS) DDGS substituted as 50% of the reference diet in place of corn. Comparisons among …

An Evaluation Of Dextrose, Lactose, And Whey Sources In Phase 2 Starter Diets For Weanling Pigs (2007), J R. Bergstrom, C N. Groesbeck, J M. Benz, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz
An Evaluation Of Dextrose, Lactose, And Whey Sources In Phase 2 Starter Diets For Weanling Pigs (2007), J R. Bergstrom, C N. Groesbeck, J M. Benz, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted to evaluate the effects of various dextrose, lactose, and whey sources on weanling pig performance. In Exp. 1, a total of 228 pigs (initially 17.1 lb) were used in a 14-d experiment. There were six treatments consisting of a control (corn-soybean meal diet) or the control diet with 7.2% lactose, 7.2% dextrose anhydrous, 7.2% dextrose monohydrate, 10% feed-grade whey, or 10% food-grade whey. Pigs were blocked by weight and randomly allotted to treatment after being fed SEW and Transition diets for the first seven days post-weaning. Overall, ADG and d 14 weight were improved (P<0.05) for pigs fed lactose or food-grade whey when compared to pigs fed feed-grade whey. There were no other differences in ADG or d 14 weights among the treatments. Average daily feed intake was improved (P<0.05) for pigs fed lactose, dextrose monohydrate, or food-grade whey when compared to those fed feed-grade whey. Feed efficiency was improved (P<0.05) for pigs fed food-grade whey rather than dextrose monohydrate. For the economic analysis, pigs fed the control diet had the lowest (P<0.01) cost per pound of gain, followed by pigs fed dextrose monohydrate, dextrose anhydrous, feed-grade whey, lactose, and food-grade whey. Margin-over-feed cost was improved (P<0.05) for pigs fed the control diet rather than the diets containing lactose, dextrose anhydrous, or either whey source. In Exp. 2, a total of 352 pigs (initially 17.1 lb) were used in a 14-d experiment to evaluate seven commercial whey sources. There were eight treatments consisting of a corn-soybean meal-based control diet and seven diets containing 10% whey, each of a different whey source. Pigs were blocked by weight and randomly allotted to treatment after being fed SEW and Transition diets for the first five days post-weaning. Overall, ADG and d 14 weight were improved (P<0.05) for pigs fed whey sources A and E when compared to the control and sources B and D. Pigs fed whey sources C, F, and G had intermediate ADG. Average daily feed intake was greater (P<0.05) for pigs fed whey source E rather than the control or whey sources B, C, D, and G. Feed efficiency was improved (P<0.05) for pigs fed whey source A rather than the control. Pigs fed the remaining whey sources had intermediate F/G. For the economic analysis, pigs fed the control diet had the lowest cost per pound of gain (P<0.01). Margin-over-feed cost was improved (P<0.05) for pigs fed the control diet rather than the diets containing whey sources B, D, and G. Pigs fed whey source A had intermediate MOF that was also greater (P<0.05) than that of pigs fed whey sources B and D. In conclusion, differences in the growth performance of pigs fed various whey (or lactose) and dextrose sources exist. The quality, cost, and relative feeding value of lactose sources should be considered when formulating diets for nursery pigs. In some cases, especially with the current high price of dried whey, feeding a Phase 2 diet containing no added source of lactose may be a more economical option despite the slight reduction in growth performance.; Swine Day, 2007, Kansas State University, Manhattan, KS, 2007

Experiments were conducted using corn ground by either a full circle, tear drop hammer mill or a three-high roller mill at the Kansas State University Grain Science Feed Mill. Flow ability was determined by measuring angle of repose. In Exp. 1 we evaluated the effects of added soy oil, glycerol, or a 50:50 soy oil/glycerol blend on the flow ability of ground corn. Samples were ground …
Validation Of Flank-To-Flank Allometric Equations In Predicting Weight Of Lactating Sows And Lactation Weight Change (2007), R C. Sulabo, Michael D. Tokach, E J. Wiedmann, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Validation Of Flank-To-Flank Allometric Equations In Predicting Weight Of Lactating Sows And Lactation Weight Change (2007), R C. Sulabo, Michael D. Tokach, E J. Wiedmann, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
The objectives of this study were to validate the use of flank-to-flank measurement in predicting weight of lactating sows and to determine the accuracy of the developed models in estimating lactation weight change. A total of 70 lactating sows (PIC Line 1050) were used in this study. Flank-to-flank measurement and body weight were measured on each individual sow after farrowing and at weaning. Flank-to-flank measurement and weight of lactating sows was positively correlated (R2 = 0.61; P<.0001) with the following equation: BW0.33, kg = 0.0371 x Flank-to-flank (cm) + 2.161. Weights of sows post-farrowing and at weaning were lower (P<0.03) when predicted with the previous allometric model developed from growing pigs and sows than their actual weights or weights predicted using the lactating sow model. Likewise, absolute residuals for post-farrowing and weaning weights using a previous allometric model developed from growing pigs and gestating sows were greater (P<0.02) than those of the lactating sow model. There were no differences (P<0.89) between the predicted weights using the lactating sow model and their actual weights. There also were no differences between the actual average weight loss (P<0.14) and the predicted loss using the lactating sow model. Using the model previously developed with growing pigs and gestating sows resulted in 15.5 lb (P<0.007) greater than the actual average weight loss. In conclusion, flank-to-flank measurement can be used as a predictor of weight of lactating sows, with the relationship having less accuracy than those used for growing-finishing pigs, gestating sows, and boars. The pig allometric equation cannot be used to estimate weights of lactating sows and lactation weight change. The developed lactating sow model was more appropriate in estimating weights and weight loss at the herd level, but needs to be validated on other sows before use can be recommended.; Swine Day, 2007, Kansas State University, Manhattan, KS, 2007
Effects Of Γ-Butyrobetaine And L-Carnitine On Carnitine Concentrations In Various Muscle Tissues Of Finishing Pigs (2007), J M. Benz, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Joel M. Derouchey, Steven S. Dritz
Effects Of Γ-Butyrobetaine And L-Carnitine On Carnitine Concentrations In Various Muscle Tissues Of Finishing Pigs (2007), J M. Benz, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Joel M. Derouchey, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
The primary method of L-carnitine production, similar to the biological process that occurs in the liver and kidneys, is from microbial fermentation of γ-Butyrobetaine. Therefore, the objective of this study was to see if supplementing the diet with γ-Butyrobetaine would increase organ and muscle tissue carnitine concentrations. One-hundred-twenty-five barrows were fed diets containing either L-carnitine (100 ppm), γ-Butyrobetaine (100 ppm) or a combination of L-carnitine (50 ppm) and γ-Butyrobetaine (50 ppm). The addition of L-carnitine, γ-Butyrobetaine and the combination of L-carnitine and γ-Butyrobetaine increased (P<0.01) free carnitine concentration in the longissimus, diaphragm, and heart. L-carnitine and the combination of L-carnitine and γ-Butyrobetaine increased (P<0.01) free carnitine concentration in the kidney. Therefore, these results suggest that γ-Butyrobetaine and/or L-carnitine can be used to increase carnitine concentrations of organ and muscle tissues.; Swine Day, 2007, Kansas State University, Manhattan, KS, 2007

Effects Of Increasing Added Choice White Grease In Corn And Sorghum-Based Diets On Growth Performance And Fat Quality Characteristics Of Finishing Pigs (2007), J M. Benz, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz
Effects Of Increasing Added Choice White Grease In Corn And Sorghum-Based Diets On Growth Performance And Fat Quality Characteristics Of Finishing Pigs (2007), J M. Benz, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
One hundred twenty crossbred barrows and gilts (TR4 × 1050) with an initial weight of 119.9 lb were used in an 83-d experiment to evaluate the effects of increasing added fat to corn or sorghum-based diets on growth performance and fat quality characteristics of finishing pigs. Treatments were arranged in a 2 × 2 × 3 factorial based on grain source (corn or sorghum), gender, and added fat (0, 2.5, or 5% choice white grease, CWG). At the end of the trial, jowl fat and backfat samples were collected. Pigs fed sorghum-based diets had increased (P<0.01) ADG compared with pigs fed corn-based diets. Pigs fed increasing CWG had increased (P<0.01) ADG. Pigs fed corn-based diets tended to have improved (P<0.06) dressing percentage, 10th rib BF, and percentage lean when compared with pigs fed sorghum-based diets. Barrows tended to have greater (P<0.06) dressing percentage and decreased (P<0.07) percentage lean when compared to gilts. Pigs fed increasing CWG had increased (P<0.02) 10th rib backfat, tended to have increased (P<0.08) hot carcass weight, and tended to have decreased (P<0.07) percentage lean. There was a fat level by grain source interaction (P<0.03) for percent C 18:2 fatty acids and iodine value in jowl fat. The interaction was due to the greatest increase in IV and percentage C 18:2 fatty acids occurring when CWG was increased from 2.5 to 5% for corn-based diets, while the greatest increase was from 0 to 2.5% CWG for sorghum-based diets. Despite this interaction, adding CWG increased (linear, P<0.02) percentage C 18:2 fatty acids and iodine value in jowl fat. Pigs fed corn-based diets had increased (P<0.01) iodine values and percentage C 18:2 fatty acids in jowl fat and backfat compared with pigs fed sorghum-based diets. Increasing dietary CWG increased (P<0.01) iodine value in jowl fat and backfat, increased (P<0.01) percentage C 18:2 fatty acids in backfat, tended to increase (P<0.06) percentage 18:2 fatty acids in jowl fat, and decreased (P<0.01) percentage saturated fatty acids in jowl fat and backfat. In summary, substituting sorghum for corn in diets for finishing pigs can be an effective way to reduce iodine value without affecting growth.; Swine Day, 2007, Kansas State University, Manhattan, KS, 2007

Kansas Agricultural Experiment Station Research Reports
A total of 1,112 pigs were used in a 78-d growth assay evaluating the effects of increasing dried distillers grains with solubles (DDGS, 0, 5, 10, 15, or 20%) on pig growth performance and carcass characteristics. At the end of the trial, jowl fat, belly fat, and backfat samples were collected and analyzed for fatty acid profile and iodine value (IV). From d 0 to 78, ADG and ADFI decreased (linear; P<0.04) with increasing DDGS with the greatest reduction occurring between pigs fed 15 and 20% DDGS. Feed efficiency tended to improve (P<0.06) for pigs fed 5% DDGS compared with those fed other dietary treatments. Increasing DDGS decreased (P<0.04) carcass weight and percent yield. There was no difference (P>0.22) in loin depth, but increasing DDGS tended to decrease (P<0.09) backfat and fat-free lean index (FFLI). Backfat, jowl fat, and belly fat iodine values and percentage C 18:2 fatty acids increased (linear, P<0.02) with increasing DDGS in both the "toppped" pigs marketed 21 d before trial conclusion and pigs marketed at trial completion. Increasing DDGS decreased (linear, P<0.05) percentage saturated fatty acids in backfat and belly fat in both marketing groups and percentage saturated fatty acids in jowl fat with increasing DDGS in the diet in the pigs marketed at trial completion. Barrows had decreased (P<0.04) belly fat iodine values and percentage 18:2 fatty acids when compared to gilts. Barrows also had increased (P<0.05) jowl fat and belly fat percentage 18:2 fatty acids when compared to gilts. Based on these results and previous research trials, dried distillers grain with solubles from this source can be fed up to 15% before seeing reductions in ADG; however, the increase in iodine value and decrease in dressing percentage must be considered in determining the economic value of DDGS.; Swine Day, 2007, Kansas State University, Manhattan, KS, 2007

Kansas Agricultural Experiment Station Research Reports
Crude glycerol is a by-product of the biofuels industry, which has the potential to be used as a feed ingredient in animal diets. However, little is known about glycerol's nutritional value or how it impacts feed quality and feed processing efficiency. Three experiments were conducted to evaluate the effects of glycerol on production efficiency of a pellet mill. In all three experiments, diets were manufactured, pelleted, and data collected at the KSU Grain Science Feed Mill. All diets were steam conditioned to 85°F and pelleted at 150°F using a CPM pellet mill equipped with a 4 mm × 32 mm …
