Processed Grain Sorghum And Grain Sorghum Combinations For Dairy Cows (1998), Evan C. Titgemeyer, James S. Drouillard, A.F. Park, John E. Shirley Jan 1998

Processed Grain Sorghum And Grain Sorghum Combinations For Dairy Cows (1998), Evan C. Titgemeyer, James S. Drouillard, A.F. Park, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

Twenty-four Holstein cows were used to evaluate the effects of processing methods on grain sorghum utilization by lactating dairy cows. No difference was observed in the utilization of steam-flaked grain sorghum and pelleted grain sorghum obtained by adding water to finely ground grain sorghum prior to extrusion and oven drying at a temperature of 200EF. Extensive processing (pelleting or steam-flaking) improved feed efficiency relative to dry rolling. Cows fed diets containing more extensively processed grains ate less feed but produced the same amount of milk as cows fed diets containing dry-rolled grain.; Dairy Day, 1998, Kansas State University, Manhattan, KS, …

Extruded-Expelled Cottonseed Meal (Express) As A Source Of Protein And Fat For Lactating Dairy Cows (1998), A.F. Park, M.V. Sheffel, Evan C. Titgemeyer, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

Twenty-four Holstein cows were used in six 4x4 Latin squares to evaluate the effects of substituting extruded-expelled cottonseed meal (Express™) for whole cottonseed and solvent soybean meal in diets for lactating cows. No differences were observed in milk and milk component yield among treatments. Percentages of fat, protein, solids-not-fat, and lactose in milk were similar among treatments. Replacing whole cottonseed with Express™ tended to reduce milk urea nitrogen but had no effect on milk protein percentage or yield. Cow acceptability of Express™ was excellent throughout the 84-day study conducted between late June and September when ambient temperature exceeded 100EF for …

Growth And Feed Efficiency Of Growing Dairy Replacement Heifers Supplemented With Rumensin Or Bovatec (1998), Michael V. Scheffel, A. Park, John F. Smith, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Ninety Holstein heifers were used to examine the effects of Rumensin® or Bovatec®. Average daily gain and feed efficiency was greater for heifers fed Rumensin® than for heifers fed Bovatec®. Heifers fed Rumensin® consumed more total dry matter per day but slightly less dry matter as a percent of body weight than heifers fed Bovatec®. No differences were observed in body condition score and hip height between dietary treatments. The primary goal of a heifer-feeding program is to obtain a desired rate of gain without fattening at the least possible cost. Results of this study support the use of Rumensin® …

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 Jan 1998

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, …

Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs (1998), I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey Jan 1998

Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs (1998), I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

In nursery pigs, enzyme supplementation generally had no effect on ADG or F/G, but a trend occurred for greater digestibility of DM in pigs fed enzymes. However, one notable interaction occurred. Enzyme supplementation gave improved F/G at the coarser (l,300 mm) particle size but not at the finer (600 or 400 mm) particle sizes. In finishing pigs, trends for better F/G and digestibilities of DM and N with enzyme supplementation occurred in one experiment (1,300 vs 600 mm) but not in the other experiment (600 vs 400). Thus, the effects of enzyme supplementation were neither large nor consistent, but wheat …

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 Jan 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

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 …

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 Jan 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

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

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to compare the nutritional adequacy ofhigh-lysine, high-oil corn (.408% lysine, 6.21% fat) and highoil corn (.289% lysine, 5.97% fat) for young growing pigs. Experiment 1 used four barrows fitted with ileal T-cannulas in a crossover design digestion study. Diets contained 8.5% casein and an equal amount of lysine from the test corn. Apparent ileal digestibilities of amino acids, GE, DM, CP, and ash were similar between diets. Experiment 2 used segregated early-weaned barrows in a 2 x 2 factorially designed growth trial. Main effects were corn type and dietary lysine (.80 or 1.15% digestible lysine). Increasing …

Effects Of Magnesium Silicate (Talc) On Feed Flow Characteristics And Growth Performance, Carcass Characteristics, And Stomach Morphology In Finishing Pigs (1998), S P. Sorrell, S L. Traylor, S L. Johnston, I H. Kim, Robert H. Hines, G A. Kennedy, Joe D. Hancock Jan 1998

Effects Of Magnesium Silicate (Talc) On Feed Flow Characteristics And Growth Performance, Carcass Characteristics, And Stomach Morphology In Finishing Pigs (1998), S P. Sorrell, S L. Traylor, S L. Johnston, I H. Kim, Robert H. Hines, G A. Kennedy, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Talc did not affect growth performance, carcass characteristics, or stomach ulceration in finishing pigs. Feeder bridging scores and coefficients of static force (the force needed to result in particle movement) were increased with added talc, both of which indicate reduced feed flowability. In a second experiment, reducing particle size from 1,050 microns to 450 microns increased the coefficients of static force, dynamic force, and angle of repose. Adding talc to either particle size diet did not improve feed flow characteristics.; Swine Day, Manhattan, KS, November 19, 1998

Characteristics Of Pelleted Wheat Middlings That Affect Summer Storage, Carl R. Reed, Dionisia M. Trigo-Stockli, Dale A. Blasi, Fred J. Fairchild

Kansas Agricultural Experiment Station Research Reports

Pelleted wheat middlings samples were collected from four Kansas flour mills in March, April, and May, 1997 to characterize their moisture content and bulk density as they would be purchased directly from the mills by a livestock producer. The average moisture content of pelleted wheat middlings was 14% as they left the mills but declined during the spring to 13.6%. Pellets purchased from Kansas mills during the summer months are likely to contain 13.0 to 13.5% moisture. The average bulk density was approximately 40 lb/ft3 , which is equivalent to about 50 lb/bu. Based on the equilibrium moisture contents determined …

Kansas Agricultural Experiment Station Research Reports

Lebanon bologna raw batter was mixed with a five-strain mixture of Escherichia coli O157:H7 to achieve average inoculum levels of 7.79, 7.77, and 7.92 log CFU/g as deter mined on MSA, 202, and PRSA media, respectively. Treatment 1 consisted of a fermentation cycle of 8 hrs at an internal temperature (I.T.) of 80EF then 24 hrs at 100EF I.T., followed by 24 hrs at 110EF I.T. Treatments 2, 3, and 4 included additional heating at 115EF I.T. for 1, 2, and 5 hrs, respectively. All heat treatments resulted in product that was negative (<1.9 log CFU/g detection limit) on all culture media and negative after enrichment on mEC selective medium. This study validates that a five-log reduction of E. coli O157:H7 can be achieved using the described protocol, thus meeting USDA/FSIS requirements.

Effects Of Added Fat, Degradable Intake Protein, And Ruminally-Protected Choline In Diets Of Finishing Steers, A.S. Flake, Gerry L. Kuhl, James S. Drouillard Jan 1998

Effects Of Added Fat, Degradable Intake Protein, And Ruminally-Protected Choline In Diets Of Finishing Steers, A.S. Flake, Gerry L. Kuhl, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

A total of 216 yearling steers was used in two finishing experiments to evaluate interactions between levels of dietary fat, protein and ruminally protected choline. In Trial 1, steers received diets that combined levels of 0% or 5% added fat (choice white grease), 10.8% or 12.5% crude protein, and 0 or 5 grams per head daily of ruminally protected choline. Steers were fed in pens of five head each for 89 days. Adding fat decreased intake (P<.01), average daily gain (P<.1), and carcass weight (P<.07) and increased carcass yield grade (P<.06) but did not alter feed efficiency (P>.9). Increasing the protein level from 10.8 to 12.5% had no significant effects on live animal performance, but the high protein level resulted …

Betaine As A Dietary Supplement For Finishing Cattle, C.A. Loest, R.D. Hunter, R.H. Wessels, James S. Drouillard, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

One hundred seventy five steers (902 lb initial body weight) were used in a finishing study to determine the effect of betaine, provided either as feed-grade betaine (Betafin-S6, Finnsugar Bioproducts) or as concentrated separator by-product (CSB; desugared beet molasses), on animal performance and carcass characteristics. Steers were fed a finishing diet based on steam-flaked and dry-rolled corn. Treatments included 10.5 or 21 g/steer daily supplemental feed-grade betaine or 250 g (15.5 betaine) or 500 g (31 g betaine) of CSB per steer daily. Dry matter intakes increased (linear, P<0.1) for steers supplemented with feed- grade betaine. Average daily gains and feed efficiencies were not affected by treatments. Dressing percent and twelfth rib back fat increased (P<0.1) for steers that received feed-grade betaine. Rib-eye area decreased (P<0.1) when steers were supplemented with either feed-grade betaine or CSB. Yield grades were significantly higher (linear, P<0.1) for cattle receiving supplemental CSB or feed-grade betaine (quadratic, P<.05). Hot carcass weights, KPH, marbling scores, and percentage of carcasses grading USDA Choice were not affected by supplemental betaine. In this study, betaine supplementation did not markedly alter growth performance, but carcass fatness tended to increase for both supplements.

Molasses-Fat Blend As An Energy Source And Conditioning Agent In Feedlot Diets, A.S. Flake, Gerry L. Kuhl, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Seventy-two yearling crossbred steers were used in an individual feeding trial to evaluate the effects of adding a molasses-fat blend (Synergy® 19/14; Cargill Molasses Liquid Products) to diets at 6 or 12% (dry basis) on growth performance, carcass traits, and feed intake behavior. Dry-rolled corn was processed to a mean geometric particle size of either 2,000 or 3,800 microns. Adding the liquid supplement at 6% to the coarse-rolled finishing ration improved gain (P<.1) and feed efficiency (P<.1). Incorporation of Synergy 19/14 into feedlot rations may help reduce fluctuations in feed intake.

Dry Aging: An Old Process Revisited, R.E. Campbell, Melvin C. Hunt Jan 1998

Dry Aging: An Old Process Revisited, R.E. Campbell, Melvin C. Hunt

Kansas Agricultural Experiment Station Research Reports

Dry aging of beef cuts, once considered the "gold standard" for premium palatability, is practiced by only a few processors. We were asked by a major southern meat purveyor to study variables of dry-aging processing. Detailed sensory analyses of flavor, juiciness, and tenderness clearly indicated that beef loins dry aged for 14 and 21 days were superior for all three traits to a product vacuum aged for 14 days and to a product dry aged for 7 days. In addition, dry- aged steaks could be vacuum packaged and stored for up to 16 days without losses in palatability. Dry aging …

Price Discovery Issues For Fed Cattle, J. Mintert, C.E. Ward, D.S. Peel, Ted C. Schroeder Jan 1998

Price Discovery Issues For Fed Cattle, J. Mintert, C.E. Ward, D.S. Peel, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Interviews were conducted with cattle feeders, beef packers, and others involved in the beef industry to discern their concerns about fed-cattle price discovery. Three issues predominated. First was the need to better identify beef quality, ideally by objective means. Quality often, but not always, referred to tenderness and the "eating experience" of consumers. Second was the need for greater pricing accuracy, signaling a desire for less average pricing and more value-based pricing. The need for improved market information was the third issue identified.

Grid Pricing Of Fed Cattle, Ted C. Schroeder Jan 1998

Grid Pricing Of Fed Cattle, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Pricing fed cattle on a value-based quality and yield grade grid provides the best opportunity for cattle producers to receive premiums associated with high quality cattle. However, grid discounts for cattle not desired by the particular packer are often quite substantial. Thus, cattle producers targeting cattle for specific grids need to have considerable knowledge regarding the quality attributes of their cattle. This study compared pricing of 202 pens of fed cattle on a live basis, a carcass (dressed) basis, and using four different packer grids. Results indicate that no single pricing method is optimal for all cattle. Producers need to …

Differences In Efficiency Among Kansas Beef Cow Producers, S. Eidson, Michael R. Langemeier, R. Jones Jan 1998

Differences In Efficiency Among Kansas Beef Cow Producers, S. Eidson, Michael R. Langemeier, R. Jones

Kansas Agricultural Experiment Station Research Reports

Beef cow producers must manage costs of production and improve production efficiency to compete with hog and poultry and other beef cattle producers. A sample of 46 beef cow enterprises from the Kansas Farm Management database was used to measure technical, economic, and overall efficiencies. On average the farms were 92% technically efficient, 80% economically efficient and 73% overall efficient. Our results suggest that 5% increases in economic and scale efficiencies would increase profit per cow by $20 and $24, respectively.

Early Detection Of Problem Implants Using Infrared Thermography, M.F. Spire, J.C. Galland, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Thermal imaging of feedlot cattle ears is a noninvasive diagnostic tool that aids in identifying properly placed or abscessed growth-promoting implants. Thirty-two calves were used to determine if abscessed and normal, functional implants could be identified and differentiated using infrared thermography. Infrared images were taken at implantation on days 2, 4, 7, 14, and 21 after implantation. Abscessed implants were easily identified. Use of thermal imaging can verify implant administration and, thus, has the potential to immediately impact feedlot quality assurance programs.
