Effects Of Poultry Fat And Choice White Grease On Pork Longissimus Muscle, Belly, And Bacon Quality (1998), J J. Engel, J W. Smith Ii, Robert D. Goodband, John A. Unruh, Michael D. Tokach, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
Eighty-four crossbred gilts were used to examine the effects of increasing dietary additions of poultry fat (PF) or choice white grease (CWG) on longissimus muscle (LM), belly, and bacon quality. Pigs fed PF had greater LM cooking loss values than those fed CWG. As PF increased in the diet, LM Minolta L* and belly lean values decreased. then increased. Neither fat source nor level significantly affected other LM quality or sensory traits. As PF increased, bacon slicing score decreased. Although all taste panel scores were well within acceptable ranges, bacon from pigs fed PF had higher sensory panel "off flavor" …

Overall ADG and ADFI were not affected, but feed efficiency was improved with pelleting and further improvements resulted from expander processing. In a second experiment, enzyme supplementation to mash, but not pelleted, diets improved feed efficiency. Indeed, F/G for pigs fed mash with enzyme was similar to that for pigs fed pelleted diets.; Swine Day, Manhattan, KS, November 19, 1998
Effects Of Sorghum Endosperm Hardness And Processing On Growth Performance And Nutrient Digestibility In Pigs And Broiler Chicks (1998), H Cao, Robert H. Hines, J S. Park, B W. Senne, J M. Jiang, J R. Froetschner, P Sorrell, Joe D. Hancock, Keith C. Behnke

In nursery pigs, the greatest digestibilities of DM, N, and OE were observed with soft sorghum. In finishing pigs, no difference was observed in digestibility of nutrients among the sorghum genotypes. Chicks fed soft sorghum had better F/G than chicks fed medium and hard sorghum. Finally, thermal processing (steam flaking and extrusion) improved ADG and F/G and digestibilities of DM, N, and GE compared to grinding (coarse and fine).; Swine Day, Manhattan, KS, November 19, 1998
Influence Of Chop Location On Boneless Pork Loin Quality (1998), A T. Waylan, R C. Johnson, John A. Unruh
Influence Of Chop Location On Boneless Pork Loin Quality (1998), A T. Waylan, R C. Johnson, John A. Unruh
Kansas Agricultural Experiment Station Research Reports
Eighty-two boneless pork loins were used to examine the effects of chop location on longissimus muscle quality. The highest quality chops came from the posterior end. They had the lowest Warner-Bratzler shear value (most tender), highest cooking yield, and a high pH and percent extractable lipid. Visual and instrumental data suggested that the most posterior chop was lighter colored and had the highest degree of marbling. Color, firmness, and marbling evaluations were similar in the central posterior section of the loin. This suggests that this section was very uniform in visual pork quality. The anterior portion of the loin was …
Expander Processing Conditions Affect Nutrient Digestibility In Finishing Pigs Fed Corn-, Sorghum-, Wheat-, And Wheat Midds-Based Diets (1998), S L. Traylor, Robert H. Hines, D J. Lee, S L. Johnston, P Sorrell, Joe D. Hancock, Keith C. Behnke
Expander Processing Conditions Affect Nutrient Digestibility In Finishing Pigs Fed Corn-, Sorghum-, Wheat-, And Wheat Midds-Based Diets (1998), S L. Traylor, Robert H. Hines, D J. Lee, S L. Johnston, P Sorrell, Joe D. Hancock, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
Expander processing of corn-, sorghum-, wheat-, and wheat midds-based diets improved nutrient digestibility in growing pigs and, thus, the apparent digestible energy concentration in the diets. This new feed manufacturing technology was especially beneficial to the feedstuff with the highest fiber content (i.e., wheat midds).; Swine Day, Manhattan, KS, November 19, 1998
Influence Of Duration Of Dietary Vitamin E Supplementation On Fresh And Cured Pork Color Stability (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband
Influence Of Duration Of Dietary Vitamin E Supplementation On Fresh And Cured Pork Color Stability (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
Supplementing finishing pigs genetically predisposed to lipid deposition with atocopheryl acetate above 12 IU/lb of feed for as long as 70 d did not improve color stability of fresh and cured pork. Tissue a-tocopherol levels were similar across dietary treatments and higher than predicted. Muscle accumulation of a-tocopherol may be related to the rate and extent of lipid deposition in muscle. Also, chill temperature and carcass chill rate variability, under spray chill conditions, did not influence fresh pork color stability when carcasses with excessive amounts of external fat were utilized.; Swine Day, Manhattan, KS, November 19, 1998
Influence Of Duration Of Dietary Vitamin E Supplementation On Swine Growth Performance And Carcass Quality (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband
Influence Of Duration Of Dietary Vitamin E Supplementation On Swine Growth Performance And Carcass Quality (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
Supplementing medium-lean genotype pigs with supranutritional concentrations of dietary vitamin E (91 IU d-a-tocopheryl acetate/lb of feed) for as long as 70 d during the finishing phase was not effective in improving swine performance, feeding characteristics, and 24 h loin muscle quality. However, lower carcass temperatures obtained by spray chilling pork sides at O°C versus 4.4°C had a beneficial effect on 24 h carcass quality by improving marbling and lean firmness scores and reducing loin muscle moisture exudate. Overall, 24 h pork carcass quality was impacted more by chill rate than dietary vitamin E supplementation.; Swine Day, Manhattan, KS, November …
Conditions During Expander Processing Of Soybean Meal And Raw Soybeans Affect Nutrient Digestibility In Finishing Pigs (1998), S L. Traylor, Robert H. Hines, N Amornthewaphat, S L. Johnson, P Sorrell, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports
Expander processing improved nutrient digestibility in diets with soybean meal and raw soybeans. Furthermore, with 600 psi cone pressure (20 k Wh/tonon ofspecific energy input), the diets with raw soybeans had equal or greater digestibility of nutrients compared to the soybean meal-based control diet.; Swine Day, Manhattan, KS, November 19, 1998
Effects Of Different Soybean Meal Processing Techniques On Growth Performance Of Pigs (1998), J C. Woodworth, R E. Musser, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband
Effects Of Different Soybean Meal Processing Techniques On Growth Performance Of Pigs (1998), J C. Woodworth, R E. Musser, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
A 35-d growth trial was conducted to determine the influence of different soybean meal processing techniques on starter pig growth performance. From d 0 to 14 after weaning, all pigs were fed a common diet. Then pigs were fed six experimental diets from d 14 to 35 after weaning. Three treatment comparisons were made. Pigs fed a diet containing extruded-expelled soybean meal (SBM) without hulls (Insta-Pro) were compared to those fed solvent-extracted SBM (46.50/0 CP) and 3.21% soy oil. Pigs fed a diet containing extruded-expelled SBM with hulls (lnsta-Pro) were compared to those fed a diet containing 44% CP SBM …

Effects Of Level Of Modified Tall Oil On Finishing Pig Growth Performance And Carcass Characteristics (1998), P R. O'Quinn, J C. Woodworth, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, John A. Unruh
Kansas Agricultural Experiment Station Research Reports
A growth trial was conducted to evaluate effects of increasing levels of modified tall oil (MTO) on growth performance and carcass composition of finishing barrows. No effect of treatment was observed for ADG, ADFI, or feed efficiency (F/G) during any of the growth periods. However, pigs fed increasing MTO had less backfat, larger longissimus muscle area, and increased percentage muscle than control pigs not fed MTO. Additionally, carcasses from pigs fed MTO had decreased drip loss. The results of this trial indicate that although MTO has no impact on growth performance in barrows, it can improve carcass leanness. The optimal …
Added Dietary Fat Improves Growth Performance And Feed Efficiency In Growing-Finishing Pigs Under Commercial Conditions (1998), S S. Dritz, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen
Added Dietary Fat Improves Growth Performance And Feed Efficiency In Growing-Finishing Pigs Under Commercial Conditions (1998), S S. Dritz, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
A total of480 pigs was used in an experiment conducted in a commercial research facility to determine the influence of fat additions to the growing-finishing diet on pig performance and carcass composition. Adding fat to the diet from 80 to 265 lb increased ADG and FIG by 1 and 2%, respectively, for each 1%added fat. The growth response was greatest during the initial phase of the trial (80 to 130 lb) and declined as the trial progressed. The feed efficiency response was consistent throughout the trial. After adjusting for the greater carcass weight of pigs consuming the high fat diets, …
Apparent Ileal Digestiblity Of Amino Acids And Digestible And Metabolizable Energy Values For Conventional Soybean Meal Or Dry Extruded-Expelled Soybean Meal For Swine (1998), J C. Woodworth, P R. O'Quinn, D A. Knabe, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen
Apparent Ileal Digestiblity Of Amino Acids And Digestible And Metabolizable Energy Values For Conventional Soybean Meal Or Dry Extruded-Expelled Soybean Meal For Swine (1998), J C. Woodworth, P R. O'Quinn, D A. Knabe, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
We conducted two experiments to determine the apparent ileal digestibility of amino acids and digestible energy (DE) and metabolizable energy (ME) values for conventionally processed, solvent-extracted soybean meal (SBM) compared to dry-extruded-expelled SBM with or without soy hulls. Apparent ileal digestibility of crude protein and lysine and DE and ME values were greater in either extruded-expelled SBM compared to the conventionally processed SBM. No differences occurred in apparent digestibility of amino acids or energy values between extruded-expelled SBM with hulls and that without hulls. These results suggest that the dry extrusion followed by expeller processing of soybeans results in a …
Effects Of Spray-Dried Egg Albumin On Growth Performance Of Early-Weaned Pigs (1998), M De La Llata, G S. Grinstead, J C. Woodworth, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz
Effects Of Spray-Dried Egg Albumin On Growth Performance Of Early-Weaned Pigs (1998), M De La Llata, G S. Grinstead, J C. Woodworth, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Seventy two early-weaned pigs (initially 12.4 lb) were used in a 14-d growth trial to evaluate a control diet (no added spray-dried egg albumin or animal plasma) or the control diet with 5% spray-dried plasma, 7% spraydried egg albumin~ or 2.5% spray-dried plasma plus 3.5% spray-dried egg albumin. Pigs fed 5% spray-dried animal plasma had greater ADG and improved F/G compared with those fed 7% spray-dried egg albumin, whereas pigs fed the control or a blend of spray-dried egg albumin plus spray-dried animal plasma had intermediate performance. These results suggest that the spray-dried egg albumin used is not an effective …

Effects Of Increasing Pantothenic Acid On Growth Performance Of Segregated Early-Weaned Pigs (1998), G S. Grinstead, R Stott, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
We conducted a 28-d experiment to evaluate effects of increasing dietary pantothenic acid on growth performance of segregated early-weaned pigs. Pigs (initially 8.8 ± 2.21b and 11 ± 2 d of age) were fed a control diet (no added pantothenic acid) or the control diet with 30, 60, and 120 ppm of added pantothenic acid. Increasing pantothenic acid increased ADG and ADFI linearly from dO to 14 after weaning. However, from d 14 to 28 after weaning, pigs fed 60 mg/kg of added pantothenic acid tended to have the greatest ADG and ADFI. For the cumulative period (d 0to 28 …
Effects Of Whole Grain And Distillers Dried Grains With Solubles From Normal And Heterowaxy Endosperm Sorghums On Growth Performance, Nutrient Digestibility, And Carcass Characteristics Of Finishing Pigs (1998), B W. Senne, Robert H. Hines, D W. Dean, I Mavromichalis, J R. Froetschner, Joe D. Hancock

Senne, Robert H. Hines, D W. Dean, I Mavromichalis, J R. Froetschner, Joe D. Hancock
Kansas Agricultural Experiment Station Research Reports
No differences occurred in ADG, ADFI, F/G, digestibilities of DM and GE, dressing percentage, 10th rib fat depth, or fat free lean index in pigs fed normal vs heterowaxy sorghums. As anticipated, with the greater fiber and lower energy in distillers dried grains with solubles (DDGS) than the parent cereal grains, ADG and digestibilities of DM and GE were lower and F/G was worse for pigs fed DDGS. However, the energy value of the DDGS was affected less adversely when heterowaxy sorghum was used for fermentation to ethanol.; Swine Day, Manhattan, KS, November 19, 1998
Influence Of High Levels Of Zinc From Zinc Oxide, Zinc Sulfate, Or A Zinc Amino Acid Complex On Starter Pig Performance (1998), J C. Woodworth, P R. O'Quinn, J A. Loughmiller, S A. Moser, T M. Fakler, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports
Three hundred and sixty early-weaned barrows were fed either a control diet; diets containing added Zn (l00, 200, 300, 400, or 500 ppm) from zinc sulfate or a zinc amino acid complex (AvailaZn); or a diet containing 3,000 ppm of additional Zn from zinc oxide. All diets contained 165 ppm of Zn from zinc oxide from the trace mineral premix. Pigs fed 3,000 ppm of Zn from zinc oxide had maximum growth performance compared to those fed other diets, whereas those fed added zinc sulfate and AvailaZn showed intermediate results relative to the negative control and the 3,000 ppm of …

Kansas Agricultural Experiment Station Research Reports
We conducted two studies to determine the effects of increasing L-lysine HCI in finishing pig diets. Experiment 1 used sorghum-soybean meal-based diets, and Exp. 2 used corn-soybean meal-based diets. Treatments included a control diet (no L-lysine HCl) or .15, .225, and .30% L-lysine HCI replacing the lysine provided by soybean meal. In Exp. 1, increasing L-lysine HCI from 0 to .150/0 had no effect on ADG, F/G, and percentage lean; however, pigs fed .225 and .30% L-Iysine HCI had poorer ADG, F/G, and percentage lean. In Exp. 2, ADG and FfG were poorer for pigs fed .225 or .30% L-lysine …

Kansas Agricultural Experiment Station Research Reports
Three hundred and sixty early-weaned barrows were fed diets containing increasing levels of added Zn from zinc oxide (0, 50, 100, 200, 400, 800, 1,600, 2,400, and 3,200 ppm). From d 11 to 21, growth performance improved with up to 100 ppm of added Zn but was not improved further until pigs were fed 3,200 ppm of added Zn. From d 21 to 36, pigs fed 100 ppm of Zn had the best growth performance. These results suggest that a pig's basal Zn requirement is met with 100 ppm of added Zn from zinc oxide, but adding 3,200 ppm Zn …
Influence Of Spirulina Platensis On Growth Performance Of Weanling Pigs (1998), G S. Grinstead, J Sawyer, K Maxwell, R Stott, A Moser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen
Influence Of Spirulina Platensis On Growth Performance Of Weanling Pigs (1998), G S. Grinstead, J Sawyer, K Maxwell, R Stott, A Moser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
We conducted three experiments to evaluate the influence of an algal feed additive, Spirulina platensis, on weanling pig performance. Two experiments conducted under commercial production conditions indicated a response to Spirulina platensis in meal-based diets but not pelleted diets. Another experiment concluded that Spirulina platensis tended to improve F/G early in the trial but not for cumulative performance. Results of these three experiments suggest that Spirulina platensis added at low inclusions to the diet may enhance performance. However, the results lacked consistency across experiments and warrant further investigation.; Swine Day, Manhattan, KS, November 19, 1998

Kansas Agricultural Experiment Station Research Reports
A total of 180 pigs (l2.961b and 21 d of age) was used in a 28 d trial to determine the effects of substituting flash-dried poultry protein for select menhaden fish meal in the phase II diet on the performance of weanling pigs. Five dietary treatments were fed from d 7 to d 28 after weaning (phase II). Select menhaden fish meal (2.5 and 5%) and flash-dried poultry protein (2.85 and 5.70/0) replaced soybean meal in the control diet on a lysine basis. Pigs fed the diets containing select menhaden fish meal and flash-dried poultry protein had similar ADG and …

Kansas Agricultural Experiment Station Research Reports
Three hundred arid fifty three lactating sows were used to determine the effects of increased dietary lysine on sow and litter performance. At farrowing, sows were assigned to com-soybean meal lactation diets consisting of either 1.0 or 1.3% total lysine. A treatment by parity interaction was observed, with first parity sows fed 1.3% lysine having heavier litter weaning weights than sows fed 1.00/0 lysine. Surprisingly, third and fourth parity sows fed 1.3% lysine had lower litter weaning weights than those fed 1.0% lysine. No other treatment by parity interactions existed. No differences were observed in the number of pigs weaned …
