Kansas Agricultural Experiment Station Research Reports
There is no rest for weary turfgrass managers in Kansas. In 2001, many of us were brought to our knees, literally -- it allowed for a better view of winter-damaged zoysiagrass, brown patch- infested tall fescue, or anthracnose-stricken creeping bentgrass. K-State's turfgrass research team is growing. We have four faculty in horticulture and one in plant pathology who dedicate their research efforts to improving turfgrass in Kansas. We also have balance, with work addressing fundamental turfgrass management problems like water management, stand establishment, weed control, and disease management. We are also striving to provide balance in serving needs across the …

Effects Of Freezing And Location Within The Beef Longissimus Muscle (Strip Loin Steak) On Tenderness, R.R. Timm, John A. Unruh, Michael E. Dikeman, Melvin C. Hunt, John E. Boyer, James L. Marsden
Kansas Agricultural Experiment Station Research Reports
Twenty-four USDA Select strip loins (IMPS 180) were aged (32°F) until 14 days postmortem and fabricated into longissimus muscle (strip loin) steaks (1-in. thick). Then, steaks were either cooked or stored at −20°F for an additional 17 days before they were thawed and cooked. Cores and sensory panel samples were removed from the medial, center, and lateral sections of each steak and locational identify maintained. In addition, a random composite of cubes from an entire steak was used for a sensory panel evaluation. Previously frozen steaks had lower Warner-Bratzler shear force (WBSF) values, less cooking loss, and a shorter cooking …

Effects Of Cooking Beef Muscles From Frozen Or Thawed States On Cooking Traits And Palatability, E. Obuz, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
We used an electric belt grill to cook steaks from two muscles; outside round (biceps femoris), and loin strip (longissimus lumborum) from both frozen and thawed states. The color values L* and a*, Warner-Bratzler shear force (WBSF), juiciness, flavor, connective tissue amount, and overall tenderness did not differ (P>0.05) between steaks cooked from frozen and thawed states. Thawed steaks cooked faster and had less cooking loss. The biceps femoris had higher WBSF than longissimus and was rated less tender by trained panelists. Color values L*, a*, or b* did not differ (P>0.05) among the muscles. The biceps femoris …

Linear Effects Of Increasing Weaning Age In Three-Site Production (2002), R G. Main, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Two studies were conducted to measure the biologic and economic effects of weaning age in a three-site production system. Wean-to-finish growth and financial performance improved linearly as weaning age increased up to 21.5 days. Data from these trials were modeled to determine the linear rates of improvement observed as weaning age increased from 15 to 21.5 days. Each day increase in weaning age increased initial weight (taken prior to weaning) 0.565 ± 0.009 lb and weight sold to slaughter 3.71 ± 0.32 lb per pig weaned. In the financial analysis, income over cost increased $0.94 ± 0.07 per wean age …

Effects Of Weaning Age On Post-Weaning Belly Nosing Behavior And Umbilical Lesions (2002), R G. Main, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz
Effects Of Weaning Age On Post-Weaning Belly Nosing Behavior And Umbilical Lesions (2002), R G. Main, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Pigs (n=2272) were weaned at 12, 15, 18, or 21 days of age to determine the effect of weaning age on post-weaning belly nosing behavior and associated umbilical lesions. A reduction (quadratic, P<0.01) in belly nosing behavior and umbilical lesions were observed as weaning age increased. The largest decrease in belly nosing behavior was observed as wean age increased from 12 to 15 days, with smaller incremental reductions in the 18 and 21 day wean pigs. This study indicates that weaning pigs at less than 15 days of age significantly increases belly nosing behavior and associated umbilical lesions after weaning.; Swine Day, Manhattan, KS, November 14, 2002

A retrospective survey of the Kansas State Veterinary Diagnostic Laboratory records was made for Escherichia coli isolated from pigs with diarrhea. There were 111 E. coli isolates that carried genes for attachment pili that are necessary for E. coli to cause diarrhea. Of the 111 isolates, 103 had one pilus gene and eight had two pilus genes. The most common pilus type was the K88 pilus accounting for 73% of the isolates. All but one of the K88 isolates also carried at least one toxin gene indicating that they were virulent for pigs. The next most common pilus type was …
Effect Of Glycine Supplementation On Sulfur Amino Acid Use In Growing Cattle, B.D. Lambert, C.A. Löest, Evan C. Titgemeyer
Effect Of Glycine Supplementation On Sulfur Amino Acid Use In Growing Cattle, B.D. Lambert, C.A. Löest, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
Previous research has suggested the possibility that the supply of glycine, a nonessential amino acid, might affect how efficiently cattle use methionine. This study was conducted to determine the role of glycine on methionine utilization in growing steers as well as how glycine might impact utilization of cysteine, an amino acid produced in the body from methionine. In Exp. 1, treatments were abomasal infusion of 2 or 5 g/day L-methionine and 0 or 50 g/day glycine in a factorial arrangement. Efficiency of methionine use was 27% in the absence of supplemental glycine, but 66% in its presence. Glycine supplementation by …

Supplementation Of L-Carnitine And Paylean Improve Growth Performance Of Pigs In A Commercial Finishing Facility (2002), B W. James, K Q. Owen, J C. Woodworth, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Our previous experiments evaluating the interactive effects of dietary L-carnitine and Paylean have primarily focused on improved meat quality benefits of feeding carnitine in combination with Paylean. Although there were numeric trends for improved growth performance in the previous experiments conducted at university facilities, the responses were not statistically significant. A recent study conducted in a commercial finishing facility demonstrated improved growth performance in pigs fed carnitine for the 4-week period prior to slaughter. The cause for the growth response observed in the commercial facility compared to the two previous studies conducted at a university research facility may have been …

Kansas Agricultural Experiment Station Research Reports
Two 35-day receiving experiments were conducted using 668 highly stressed crossbred beef heifers to evaluate differences in growth performance, morbidity, and mortality when fed diets containing differing sources of dietary lipid. Heifers received diets containing beef tallow, tallow enriched with a microalgae product containing a high proportion of docosahexaenoic acid (an omega-3 fatty acid), full-fat soybeans, or ground flaxseed. All diets contained approximately 60% concentrate and 40% roughage (alfalfa hay). Feed intake, daily gain, and feed efficiency were poorer (P<0.05) for cattle fed full-fat soybeans than for those fed the other treatments. Feed intake tended to be reduced when micro-algae was top-dressed to the diet, but gain was not negatively impacted. In Trial 2, feed efficiency was improved by the micro-algae. No notable differences among treatments were evident in the percentage of cattle treated for bovine respiratory disease, but cattle fed flaxseed tended to respond better to therapeutic treatments, requiring fewer retreatments.

Performance And Carcass Characteristics Of Finishing Steers Fed Dried, Full-Fat Corn Germ, T.J. Kessen, M.J. Sulpizio, M.F. Spire, R.T. Ethington, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Three hundred and fifty-eight crossbred beef steers (average initial weight 701 lb) were fed finishing diets containing 0, 5, 10, or 15% full-fat corn germ to evaluate effects on growth performance and carcass characteristics. Steers were placed into dirt-surfaced feedlot pens (12 to 16 head each) in December 2000 with a total of six pens per diet. Average daily gains during the 155-day finishing period were 2.83, 2.99, 3.01 and 2.93 lb/day for cattle fed 0, 5, 10, and 15% corn germ, respectively. Dry matter intakes decreased linearly (P<0.05) with increasing concentrations of full-fat corn germ in the diet. Relative to cattle fed no corn germ, efficiencies were improved by 8, 11, and 9% for cattle fed 5, 10, or 15% germ, respectively. Feeding corn germ also reduced the incidence of liver abscesses (P<0.05) compared to cattle fed the control diet. Dried, full-fat corn germ can be used successfully in cattle finishing diets to increase energy density and animal performance.

Effect Of Methionine Supplementation On Methionine Metabolism In Growing Cattle, B.D. Lambert, C.A. Löest, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
Methionine is often the first limiting amino acid for growing cattle. This study was conducted to determine how methionine metabolism is regulated in the liver of growing steers. Six ruminally cannulated steers were used in a replicated 3 x 3 Latin square experiment. Either 0, 5, or 10 g/day L-methionine was infused into the abomasum. These treatments were designed to be deficient, adequate, and in excess of the steers' requirements for methionine. Methionine supplementation linearly increased protein deposition and decreased the activity of methionine synthase (a methionine conserving enzyme). However, it had little effect on activity of cystathionine synthase (an …

Steam-Flaked Corn Diets Containing Combinations Of Wet Corn Gluten Feed And Alfalfa Hay: Effects On Diet Digestibility And Ruminal Characteristics, J.J. Sindt, Sean P. Montgomery, J.N. Pike, T.B. Farran, C.M. Coetzer, James J. Higgins, James S. Drouillard, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
Twelve ruminally cannulated Jersey steers were used to measure digestibility and ruminal characteristics of steam-flaked corn based diets containing combinations of wet corn gluten feed (WCGF) and alfalfa hay (AH). Starch intake was lower (P<0.05), but neutral detergent fiber intake was higher (P<0.05) as AH and WCGF increased in the diet. Ruminal pH was increased by AH (linear, P<0.05) and tended (P<0.07) to increase with WCGF. Feeding higher levels of WCGF tended to increase passage rate (P=0.17) and decreased (P<0.05) total tract organic matter digestibility. Flaked corn diets containing at least 25% WCGF may contribute enough roughage to allow reduction of alfalfa hay levels.

This study determined the ability of Clostridium perfringens spores to germinate and grow after different organic acid treatments in vacuum packaged cooked ground beef subjected to substandard (slow) cooling. Meat samples were inoculated with a three-strain cocktail of C. perfringens spores (ATCC 10388, NCTC 8238, and NCTC 8239), then vacuum-packaged, cooked in a water bath to 167°F internal temperature, and held 20 min. The water bath temperature was then lowered to 130°F, and samples were cooled from 130°F to 45°F over 18 hr. Samples were taken after inoculation, after cooking, and after cooling. In the event of substandard cooling, sodium …

Prevalence Of Mycoplasma Bovis In Bovine Pneumonia And Arthritis, T. Yeary, Jerome C. Nietfeld
Kansas Agricultural Experiment Station Research Reports
Samples from cattle with pneumonia and/or arthritis were cultured for Mycoplasma. When requested, the Mycoplasma isolates were further identified to species by polymerase chain reaction or restriction fragment length polymorphism. The records of all cases where mycoplasma testing was performed were examined and other infectious agents known to cause pneumonia or arthritis were recorded. Mycoplasma species were isolated from 85% of the lung samples and 69% of the joint samples. Eighty-four percent of the 81 Mycoplasma isolates that were further identified were M. bovis, which clearly made it the most common pathogenic agent identified in samples from cattle with pneumonia …

One hundred sixty spring-calving Hereford x Angus cows grazing low-quality, tallgrass-prairie range during the winter of 2000-2001 were supplemented before calving either daily or three times weekly. The supplement contained 40% CP with 0, 15, 30, or 45% of the supplemental degradable intake protein from urea. Supplement was fed at 4 lbs/head daily to cows receiving supplement daily. Cows receiving supplement three times weekly were fed the same amount of weekly supplement, but split equally among their supplementation events. After calving, all cows received a supplement without urea on a daily basis. In general, prepartum supplements that contained more urea …
The Effect Of Aureomycin® In Combination With Bovetec® In A Mineral Mixture On Steers Grazing Native Grass, F.K. Brazle
The Effect Of Aureomycin® In Combination With Bovetec® In A Mineral Mixture On Steers Grazing Native Grass, F.K. Brazle
Kansas Agricultural Experiment Station Research Reports
Three hundred twelve mixed-breed steers (590 lb) were allotted randomly to eight native grass pastures on April 20. The pastures were grazed until July 13. The steers in four pastures received a basic mineral mix with 800 mg of Bovatec7 per lb. The other four pastures received the basic mineral mixture with Bovatec plus 1.6 lb Aureomycin 50 per 50 lb of mineral. The steers receiving the mineral with Aureomycin had greater mineral consumption (P<0.04). Including Aureomycin in the mineral increased gain by 2%; however, the response was not statistically significant.

The K-State Research and Extension Forage Task Force surveyed Kansas rangelands during the course of seasonal changes to enable producers and managers to better estimate the feed value of their pasture forage during particular times of the year. Kansas' two distinct rangeland vegetation types, shortgrass and tallgrass prairie, were evaluated. Forage samples were collected monthly from two rangeland sites in each of 10 Kansas counties. Tallgrass vegetation was lowest in acid detergent fiber (ADF) and greatest in crude protein (CP) from May to July, and rapidly increased in ADF and declined in CP the rest of the season. Shortgrass vegetation …
