Kansas Agricultural Experiment Station Research Reports
A total of 1,160 barrows (PIC, initially 68.4 lb) were used in a 70-d study to determine the influence of dried distillers grains with solubles (DDGS) and glycerol on pork loin quality attributes. The pigs were blocked by weight and randomly assigned to 1 of 6 dietary treatments with 7 replications per treatment. Pigs were fed corn-soybean meal-based diets with the addition of DDGS, glycerol, or a combination of these. The treatments were arranged in a 2 × 3 factorial with main effects of DDGS (0 or 20%) and glycerol (0, 2.5, or 5%). Pork loins from the 2 heaviest …

Effects Of Expander Conditioning On The Nutritional Value Of Diets With Dried Distillers Grains With Solubles In Nursery And Finishing Pigs (2008), C Feoli, Terry L. Gugle, S D. Carter, Joe D. Hancock, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
Three experiments were conducted to determine the effects of expander conditioning on nutritional value of diets without and with corn- and sorghum-based dried distillers grains with solubles (DDGS). In Exp. 1, 180 nursery pigs (average weight 29 lb) were assigned to 30 pens. Treatments were arranged as a 3 × 2 factorial with main effects of diet formulation (corn-soybean meal vs. 30% corn- or sorghum-based DDGS) and conditioning (standard steam vs. expander) prior to pelleting. Pigs fed corn-soybean meal diets had better (P<0.005) ADG, F/G, and digestibility of DM, N, and GE than pigs fed diets with DDGS. Diets with corn-based DDGS supported better (P<0.03) ADG, F/G, and digestibility of DM and N than diets with sorghum-based DDGS. Expander processing improved (P<0.009) ADG, F/G, and digestibility of DM, N, and GE compared with standard conditioning. Pigs fed diets with sorghum-based DDGS showed the greatest response in F/G to expander conditioning leading to a DDGS source × conditioning interaction (P<0.008). In Exp. 2, 176 finishing pigs (average weight 164 lb) were assigned to 16 pens. Treatments were arranged as a 2 × 2 factorial with main effects of diet formulation (corn-soybean meal vs. 40% sorghum-based DDGS) and conditioning (standard steam vs. ex-pander) prior to pelleting. Net electrical energy required for feed processing was lower (P<0.001) and production rate was greater (P<0.005) for the corn-soybean meal diets than for diets with DDGS. However, pellet durability was improved (P<0.001) by addition of DDGS to the diets. Pigs fed corn-soybean meal diets had better (P<0.03) overall ADG and F/G than pigs fed diets with DDGS. Expander conditioning did not affect ADG (P>0.83) but improved overall F/G and dressing percentage (P<0.007). In Exp. 3, 192 finishing pigs (average weight 222 lb) were assigned to 16 pens to determine nutrient digestibility. Treatments were the same as in Exp. 2. Feed and water was consumed ad libitum during a 6-d adjustment period; then, feces were collected for 2 d. Corn-soybean meal diets had greater (P<0.001) digestibility of DM, N, and GE than diets with DDGS, and expander conditioning improved (P<0.02) digestibility of DM, N, and GE compared with standard conditioning. However, the improved digestibility of DM with expander conditioning was apparent primarily for the DDGS diets (diet × conditioning interaction, P<0.01). In conclusion, expanding diets improved ADG, F/G, and nutrient digestibility in nursery pigs and F/G, dressing percentage, and nutrient digestibility in finishing pigs fed diets without and with DDGS.; Swine Day, 2008, Kansas State University, Manhattan, KS, 2008
Effects Of Different Feeding Regimens On Growth, Longevity, And Semen Characteristics Of Working Boars In A Commercial Ai Stud (2008), R C. Sulabo, J Quackenbush, Robert D. Goodband, Michael D. Tokach, Joel M. Derouchey, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports
The objective of the study was to determine the effects of 2 different feeding regimens on growth performance, semen production and quality, and longevity of boars in a commercial AI stud. A total of 30 replacement boars (PIC TR4, 375 lb and 14.2 mo of age) were randomly selected and allotted to 1 of 2 treatments. The control feeding program was the normal feeding program of the stud; boars were fed 6.7 lb/d for the first 8 wk, and then feeding was adjusted according to body condition of the individual boar. For the treatment feeding program, boars were fed 5.8 …

Kansas Agricultural Experiment Station Research Reports
Two 28-d experiments were conducted to determine the effects of increasing dietary zinc and copper levels on weanling pig performance. In each experiment, 180 weanling pigs (PIC, 21 d of age, 12.5 lb in Exp. 1 and 13.2 lb in Exp. 2) were allotted to 1 of 6 treatments with 5 and 6 replications in Exp. 1 and 2, respectively. Diets were fed in 2 phases (d 0 to 14 and 14 to 28), and the trace mineral premix provided 165 ppm zinc and 16.5 ppm copper to all diets. In Exp. 1, treatments were arranged as a 2 × …
Effects Of Adding Saturated Fat To Diets With Sorghum-Based Dried Distillers Grains With Solubles On Growth Performance And Carcass Characteristics In Finishing Pigs (2008), C Feoli, Donald H. Kropf, S Issa, Terry L. Gugle, S D. Carter, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted to determine the effects of adding sources of saturated fat to diets with sorghum-based dried distillers grains with solubles (DDGS). For Exp. 1, 112 barrows (initially 140 lb) were used in a 69-d growth assay with 7 pigs per pen and 4 pens per treatment. Treatments were a corn-soybean meal-based control and diets having 40% sorghum-based DDGS (U.S. En-ergy Partners, Russell, KS) without and with 5% added tallow or palm oil. Feed and water were consumed on an ad libitum basis until pigs were slaughtered (average BW 283 lb) to allow collection of carcass data and …
