Kansas Agricultural Experiment Station Research Reports
A total of 1,440 pigs (initially 22.5 lb and 21 d after weaning) was used in a 21-d growth assay to determine the optimal lysine level to maximize growth performance of 22- to 45-lb pigs. Pigs were fed one of five dietary treatments with increasing dietary lysine (1.1, 1.2, 1.3, 1.4 and 1.5% true digestible lysine). All diets had the same soybean meal level with crystalline amino acids added to achieve the increasing lysine levels while maintaining a minimum ratio of all other amino acids to lysine. Average daily gain and feed efficiency improved linearly (P<0.01) with increasing dietary lysine. Although the response to lysine was linear (P<0.01), it would appear that pigs weighing between 22 and 45 lb require approximately 1.4% true digestible lysine (1.54% total lysine) to maximize growth performance.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003

Kansas Agricultural Experiment Station Research Reports
Twelve multiparous sows were utilized in a randomized complete block design to determine the effects of feeding diets with or without Carnichrome® (50 ppm carnitine and 200 ppb chromium picolonate) on the components of heat production (HP) in early, mid and late gestation. All sows were fed dietary treatments for the 28 d lactation, and the subsequent weaning to estrus and gestation periods. The kinetics of HP and its partitioning (basal or resting HP, activity HP, and short term thermic effect of feeding (TEFst)) were determined during three stages of gestation, early (weeks 5 or 6), mid (weeks 9 or …
Effects Of Increasing Crystalline Amino Acids And The Subsequent Change In Diet Net Energy On Growing Pig Performance (2003), M U. Steidinger, J L. Usry, Michael D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Effects Of Increasing Crystalline Amino Acids And The Subsequent Change In Diet Net Energy On Growing Pig Performance (2003), M U. Steidinger, J L. Usry, Michael D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Three individual trials were conducted to evaluate the effect of increasing the amount of crystalline amino acids (L-lysine, L threonine, and DL-methionine) as a replacement for soybean meal in the diet on pig growth performance. A second objective was to determine if increasing net energy (NE) concentration in the diet as a result of increased crystalline amino acids and less soybean meal would affect pig growth. In all three studies, pigs (each approximately 21 lb) were fed a cornsoybean meal diet, or diets with 2, 4, 6, or 8 lb/ton L-lysine HCl and other amino acids to maintain their proper …

Estimates Of Parameters Between Direct And Maternal Genetic Effects For Weaning Weight And Genetic Effects For Carcass Traits In Crossbred Cattle (2003), R.K. Splan, L.V. Cundiff, L.D. Van Vleck, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Estimates of heritabilities and genetic correlations were obtained from weaning weight records of 23,681 crossbred steers and heifers, and carcass data of 4,094 crossbred steers using REML applied to animal models. Direct and maternal heritabilities for weaning weight were 0.14 and 0.19, respectively. The genetic correlation between direct and maternal weaning weight was negative (-0.18). Heritabilities for carcass traits of steers were moderate to large (0.34 to 0.60). Genetic correlations between direct genetic effects for weaning weight and carcass traits were small, except with hot carcass weight (0.70), ribeye area (0.29) and adjusted fat thickness (0.26). Genetic correlations of maternal …
Inhibition Of Heterocyclic Amine Formation In Beef Patties With Added Spices And Ingredients, S. Hinojosa Verdin, K.A. Hachmeister, J. Scott Smith
Inhibition Of Heterocyclic Amine Formation In Beef Patties With Added Spices And Ingredients, S. Hinojosa Verdin, K.A. Hachmeister, J. Scott Smith
Kansas Agricultural Experiment Station Research Reports
Heterocyclic amines (HCAs) are compounds present at part per billion levels in fried, grilled, broiled, barbecued and smoked meats. Most of these compounds are highly mutagenic, as demonstrated by the Ames test using Salmonella typhimurium. They also are carcinogenic in rodents and non-human primates following high dosage and long term oral administration. For decades, researchers have focused on inhibiting the production of these carcinogens. This research investigates the effects of natural antioxidants in spices or other ingredients on the reduction of heterocyclic amines formation when beef patties are cooked. The term "spice" in this paper includes herbs. Ground beef patties …

Evaluation Of Mechanical Probes Used On Uncooked Steaks To Classify Beef Longissimus Tenderness (2003), J.W. Stephens, Melvin C. Hunt, T.E. Lawrence, T.M. Loughin, John A. Unruh, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
We pooled the mechanical probe data from two experiments to develop regression equations to predict beef longissimus tenderness. Fifty-three USDA Select strip loins were evaluated at 2 days postmortem with three mechanical probes to predict trained sensory panel (TSP) tenderness and Warner-Bratzler shear force (WBSF) of cooked steaks aged 14 days. The sharp needle, sharp blade, and plumb bob probes were correlated to TSP tenderness (r=-0.51, -0.45, and -0.35, respectively)and WBSF (r=0.56, 0.53, and 0.36, respectively). Regression equations developed from sharp needle, sharp blade, and plumb bob probe measurements and L* (lightness) values accounted for 49, 50, and 47% of …

Modeling Of Cooking Strip Loin And Outside Round Steaks In A Forced-Air Convection Oven (2003), E. Obuz, Larry E. Erickson, Melvin C. Hunt, T.J. Herald, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
We used a forced-air convection oven to cook steaks from two muscles; strip loin (longissimus lumborum) and outside round (biceps femoris). We used a mathematical model to predict cooking time and temperature profiles for each steak. No differences (P>0.05) were found in cooking times between experimental and model values for either of the steaks. Modeled temperature profiles were consistently higher (except for the beginning of the cooking cycle) than the experimental values up to 65°C (150°F) in the cooking cycle for outside round steaks, whereas better agreement between experimental and modeled values was found for strip loin steaks. A …

Kansas Agricultural Experiment Station Research Reports
This experiment determined the impact of type of supplemental carbohydrate and amount of supplemental ruminally degradable protein (RDP) on intake and digestion of prairie hay. Fourteen ruminally fistulated beef steers were supplemented with one of two carbohydrates (corn starch or the simple sugar glucose) at 0.30% of body weight and one of seven levels of ruminally degradable protein (RDP; 0, 0.015, 0.051, 0.087, 0.123, 0.159, or 0.195% of body weight). Two additional steers served as controls (non-supplemented steers, i.e., no carbohydrate or RDP supplementation). Forage intake and digestion were substantially improved by increasing amounts of supplemental RDP. Supplemental carbohydrate with …
Effect Of Feeding Conventional Or High-Moisture, Steam-Flaked Corn To Finishing Heifers (2003), J.J. Sindt, T.J. Kessen, M.J. Sulpizio, E.R. Loe, Sean P. Montgomery, James S. Drouillard
Effect Of Feeding Conventional Or High-Moisture, Steam-Flaked Corn To Finishing Heifers (2003), J.J. Sindt, T.J. Kessen, M.J. Sulpizio, E.R. Loe, Sean P. Montgomery, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Finishing heifers were fed diets containing either conventional (18% moisture) or high-moisture (36% moisture) steam-flaked corn. Increasing moisture concentration in flakes increased starch availability (P<0.01), but feeding heifers high-moisture flakes decreased (P<0.05) dry matter intake and average daily gain compared to heifers fed conventional flakes. Feeding heifers high-moisture flakes also numerically reduced hot carcass weight and ribeye area, but caused (P<0.01) heifers to deposit more fat over their 12th rib. Extreme levels of moisture in flaked corn improve starch availability but do not appear to increase heifer performance or carcass value. The interaction between moisture and flake density needs further evaluation.

Kansas Agricultural Experiment Station Research Reports
Three experiments were conducted using 486 weanling pigs (216 in Experiment 1; 210 in Experiment 2; 60 in Experiment 3) to determine the effects of different soy protein concentrate (SPC) sources on growth performance. Soy protein concentrate source 1 is dried with a torus disk following the concentration of soy proteins. This drying procedure will generate some degree of heat and possibly mechanical forces somewhat similar to extrusion processing (Soycomil P®, ADM). Soy protein concentrate source 2 is dried by a different process, and then it is moist extruded (Profine E, Central Soya). Therefore, the objective of our study was …

Kansas Agricultural Experiment Station Research Reports
Previous research at Kansas State University indicated that irradiation can effectively reduce the bacteria concentration in nursery diets. Therefore, we hypothesized that eliminating bacteria in the feed via irradiation would provide a model to determine the effectiveness of antimicrobial alternatives. In a 27-d growth assay, 330 weanling pigs (13.2 lb and 18 ± 2 d of age, PIC) were fed one of 9 experimental diets: 1) control diet with no antimicrobials, 2) irradiated control diet with no antimicrobials, and the irradiated control diet with added: 3) carbadox (50 g/ton), 4) Probios® (1.6% from d 0 to 14 and 0.8% from …

Kansas Agricultural Experiment Station Research Reports
A total of 276 pigs (initially 21.9 lb) was used to determine the effects of added Hemicell® on growth performance. Hemicell® is a patented fermentation product of Bacillus lentus. The active ingredient in the fermentation product is β-mannanase. However, other enzymes such as amylase, xylanase, cellulases, and α-galactosidase also are present. It is claimed that Hemicell® degrades β-mannan in feed, thus, removing its effects as an antinutritive factor in swine diets. Dietary treatments were arranged as a 2 x 3 factorial, with or without 0.05% Hemicell®, in diets with 3 levels of energy density (1,388, 1,488, 1,588 ME, kcal/lb). The …

The Influence Of Dietary Fat Level And Crystalline Amino Acid Additions On Growth Performance Of 25- To 50-Lb Pigs (2003), J Usry, Michael D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
The Influence Of Dietary Fat Level And Crystalline Amino Acid Additions On Growth Performance Of 25- To 50-Lb Pigs (2003), J Usry, Michael D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
To determine the effects of increasing added fat on pig growth performance 1,440 pigs (each initially 26 lb) were used in a 21 d growth trial. Pigs were fed diets containing none, 1.5, 3.0, 4.5, and 6.0% choice white grease. Increasing added fat reduced (linear, P<0.05) ADFI and improved F/G. Although ADG was not significantly affected by fat level, increasing added fat from 0 to 1.5% or greater resulted in a 1-lb increase in total weight gain over the entire trial. The greatest improvement in feed efficiency was also observed with the addition of the first 1.5% fat; however, further increases in dietary fat continued to linearly reduce ADFI and improve F/G. These results would suggest that from 25 to 50 lb, 1.5 to 3.0% added fat optimized pig growth performance. Based on the results of Experiment 1, we conducted Experiment 2 to confirm the optimum level of added fat in combination with increased use of crystalline amino acids (3 vs 6 lb/ton L-lysine + other amino acids) to meet the pig's lysine requirements. In Experiment 2, 1,152 pigs (each initially 21 lb) were fed one of four dietary treatments arranged in a 2 x 2 factorial. Main effects included added fat (3 or 6%) and crystalline amino acid amounts (3 vs 6 lb/ton Llysine HCl with other amino acids added to maintain proper amino acid to lysine ratios). No differences were observed in growth performance, but based on current ingredient prices, reducing the amount of soybean meal by the use of higher levels of crystalline amino acids increased margin over feed cost. In conclusion, these data indicate that 3% added fat will optimize growth performance and margin over feed costs, and that the use of greater amounts of crystalline amino acids (up to 6 lb/ton L-lysine with added L-threonine and DL methionine) are efficiently used by the pig and will also help further increase margin over feed costs.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003

Effect Of Information And Information Source On Consumer Preference For Food Irradiation, John A. Fox, Michael A. Boland, W. Grady
Kansas Agricultural Experiment Station Research Reports
The effect of consumer information about food irradiation and the source of the information was studied through a survey mailed to 400 residents each of Manhattan and Topeka, Kansas. Two-thirds of the surveys contained a brochure providing answers to frequently asked questions about irradiation, one-third did not. Half of the informational brochures were altered to suggest they were from industry, half from the government. The survey questioned consumer choice between irradiated and non-irradiated ground beef patties, with price differentials from 10 cents/lb to 40 cents/lb costlier for irradiated patties. A greater price differential resulted in less preference for irradiated beef …

Particle Size Of Corn In Lactation Diets For Mixed-Parity Sows (2003), E C. Baudon, Joe D. Hancock, Michael D. Tokach
Kansas Agricultural Experiment Station Research Reports
A total of 107 mixed-parity sows (parities one to four) was used to determine the effects of particle size of corn in lactation diets on sow and litter performance. The sows were fed corn-soybean meal-based diets with targeted corn particle sizes of 1,500, 900, and 600 μm (actual means particle sizes of corn during the experiment were 1,600, 824 and 619 μm). Reducing mean particle size of the corn in lactation diets from 1,500 to 600 microns resulted in greater ADFI and water usage (linear effects, P<0.02), fewer days for return to estrus after weaning (linear effect, P<0.04), and less backfat loss (quadratic effect, P<0.03) for the sows. Although the trends in pigs weaned per litter, piglet survivability, litter weaning weight, and litter weight gain were in the same direction as those for feed intake and water usage in the sows, the difference in measurements of litter performance was not statistically important among treatments (P = 0.15 or greater). Intakes of DM, N, and GE by the sows were increased by 9, 4, and 7% and apparent digestibilities of DM, N, and GE were increased by 6, 5, and 7%, respectively, as particle size of corn was decreased from 1,500 to 600 μm (linear effects, P<0.001). Finally, excretion of DM and N in the feces was decreased (linear effect, P<0.002) by 178 g/d and 5 g/d, respectively, as particle size of the corn on the sow diets was reduced. In conclusion, reducing particle size of corn did not affect litter performance but increased feed intake and digestibility of nutrients and reduced nutrient excretion in sows.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003

Kansas Agricultural Experiment Station Research Reports
We studied the antimicrobial efficacy of buffered sodium citrate and a combination of buffered sodium citrate and sodium diacetate on natural aerobic microflora of ground beef stored at 39°F. For non-treated control and 1% buffered sodium citrate, total aerobic count gradually increased from 4.2 log colony forming units (CFU)/gram initially to 9.0 and 8.7 log CFU/gram, respectively, after 10 days. Both treatments reached the spoilage index number of 7.0 log CFU/gram after 5 days. A combination of 1% buffered sodium citrate and 0.1% sodium diacetate resulted in a total aerobic count of 5.9 log CFU/gram (below the spoilage index) after …

Kansas Agricultural Experiment Station Research Reports
Fifty-four crossbred finishing steers were used to measure the effects of reducing supplemental protein (nitrogen) on feedlot performance and fecal shedding of acid-resistant Escherichia coli and total coliform bacteria. A control diet (15.0% crude protein; high protein) was compared to a low protein diet (8.9% crude protein; low protein) from which supplemental nitrogen sources (urea and soybean meal) were removed for the last 8 days of the feeding period. Fecal E. coli and coliform populations were measured prior to harvest. Removal of supplemental nitrogen from feedlot cattle diets did not substantially reduce populations of acid-resistant fecal E. coli and coliforms. …

Kansas Agricultural Experiment Station Research Reports
A 32-day growth study with a total of 252 weanling pigs (18 ± 3 d of age) was conducted to evaluate the effects of a prebiotic, Inulin (a fructooligosaccharide derivative of chicory), and a direct fed microbial (Lactobacillus strain) in diets for weanling pigs. Pigs were fed one of six experimental diets containing: 1) no antibiotic or prebiotic (negative control); 2) carbadox (50 g/ton, positive control); 3) direct fed microbial (DFM, 0.1%); 4) Inulin (0.5% and 0.2% of phase I and phase II diets, respectively); 5) carbadox plus DFM; or 6) carbadox plus Inulin. Pigs fed carbadox improved (P<0.04) ADG from d 0 to 14, 14 to 32, and overall (0 to 32) compared to pigs fed diets without carbadox. Pigs fed diets containing carbadox increased (P<0.01) ADFI from d 0 to 14 and tended to have increased (P<0.06) ADFI overall compared to pigs fed diets without carbadox. No differences in ADG or ADFI were seen for pigs fed diets containing either Inulin or the DFM compared to pigs fed diets without Inulin or DFM. Pigs fed the DFM had poorer feed efficiency d 0 to 14 (P<0.03), 14 to 32 (P<0.01), and overall (P<0.01) compared to those fed diets without DFM. Also, there was a trend for pigs fed diets containing Inulin to have poorer feed efficiency (P<0.07) from d 14 to 32 and overall when compared to pigs fed diets without Inulin. There were no additive responses for ADG or ADFI when Inulin or DFM were combined with carbadox. Pigs fed diets containing both the DFM and carbadox resulted in poorer feed efficiency (P<0.02) from d 14 to 32 and overall (0 to 32) than pigs fed diets without carbadox or DFM. Pigs fed the diet containing Inulin and carbadox had poorer feed efficiency from d 0 to 14 (P<0.04) compared to pigs fed diets without carbadox or Inulin. In summary, nursery diets containing either Inulin or the DFM did not enhance growth performance; however, carbadox improved ADG and ADFI.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003
