We used high-health status, weanling pigs to evaluate six different protein sources as replacements for spray-dried animal plasma. Spray-dried blood meal, spray-dried egg, spray-dried wheat gluten, extruded soy protein concentrate, select menhaden fish meal, and soybean meal each replaced 2.5 or 5.0% spray-dried animal plasma. Pigs fed increasing levels of spray-dried blood meal, spray-dried egg, or soybean meal had decreased ADFI; however, increasing levels of select menhaden fish meal, extruded soy protein concentrate, and spray-dried wheat gluten had no influence or increased ADFI. For the high-health pigs used in this trial, select menhaden fish meal, extruded soy protein concentrate, and …

The Impact Of Selected Hog Carcass Traits On Prices Received (1996), J Mintert, Steven S. Dritz, Ted C. Schroeder, S Hedges
Kansas Agricultural Experiment Station Research Reports
Hog producers can control the quality of the hogs they market. Through genetic selection and management, producers can have a large impact on hog carcass characteristics such as weight, backfat depth, and loin depth. Determining how much emphasis to place on changing or managing various carcass traits requires knowledge of the trait's value to the individual producer. Results from this study provide information on expected changes in price at one major midwestern packer associated with changes in carcass weight, backfat depth, and loin depth. Number of hogs marketed in each group did not affect net carcass value. However, these results …

Thirty six Yorkshire gilts (initially 123 lb BW) were used to investigate the effect of dietary carnitine on growth performance, carcass characteristics, fatty acid oxidation, and enzyme kinetics. Dietary carnitine reduced fat deposition in favor of protein deposition, stimulated fatty acid oxidation, induced the expression of pyruvate carboxylase, increased the capacity of pyruvate carboxylase flux, and decreased the capacity of branch chain keto-dehydrogenase.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports
Finishing gilts (initially 163 lb) were fed .58% total lysine (.50% apparent digestible) and total sulfur amino acid (TSAA) concentrations of .26, .285, .31, .335, and .36% (.225 to .325% apparent digestible). These values represent TSAA: lysine ratios of 45, 50, 55, 60, and 65%. Results suggest a linear decrease in ADG and ADFI along with poorer F/G with increasing TSAA levels. However, gilts fed .285% TSAA (50% of lysine) had the best ADG and F/G. No effect was observed on any carcass criteria. Based on the results of this study, the TSAA requirement is not greater than .285% total …

Determination Of Contract Base Payments To Feeder-Pig Producers (1996), J L. Parcell, Michael R. Langemeier
Kansas Agricultural Experiment Station Research Reports
Risks associated with independent feeder-pig production have prompted producers to seek alternative production and marketing methods. A means of reducing risk has developed through contract feeder-pig producing. Research results indicate that slightly risk-averse producers required contract base payments ranging from $7.50 to $28.50 per head. Strongly risk-averse producers required contract base payments ranging from $2.50 to $17.75 per head. The lower end of the ranges is for a low-profit producer. The upper end of the ranges is for a high-profit producer.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports
Sixty four gilts (initially 120 lb) were used to evaluate the effects of increasing total sulfur amino acid (TSAA):lysine ratios on growth performance and carcass characteristics. Diets included two levels of lysine (.55% and .70% total lysine) and three TSAA:lysine ratios (60, 65, and 70% of lysine) arranged in a 2 x 3 factorial. A tendency for a lysine x TSAA interaction was observed for ADG and ADFI. Increasing TSAA:lysine ratio decreased ADG and ADFI in pigs fed .55% lysine; however, ADG and ADFI were increased in pigs fed .70% lysine and 65% TSAA:lysine. Pigs fed .70% lysine had improved …

Steam Pasteurization Of Beef Carcasses, D.E. Schafer, R.K. Prasai, Abbey L. Nutsch, Randall K. Phebus, John R. Wolf, John A. Unruh, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
This research evaluated the effectiveness of a newly patented steam-pasteurization process for reducing bacterial populations on the surfaces of freshly slaughtered beef carcasses. The process was developed jointly by Frigoscandia Food Processing Systems (Bellevue, WA) and Excel Corp. (Wichita, KS), a division of Cargill (Minneapolis, MN). In laboratory studies, portions of prerigor beef carcasses inoculated with very high levels of three pathogens, Salmonella, Escherichia coli O157:H7, and Listeria, were treated in a prototype steam-pasteurization chamber, which effectively eliminated at least 99.9% of all three pathogens and was most effective when used in combination with other standard commercial decontamination methods.

Irradiation had minimal effects on flavor and texture of frozen or chilled vacuum-packaged boneless beef steaks. A dose level of 3.5 kilograys (kGy) reduced beef aroma in chilled steaks. Irradiation did not influence internal or external cooked color, most raw color traits, cooking loss, pH, oxidative rancidity, or Warner-Bratzler shear force in chilled or frozen boneless steaks. PVC-wrapped controls were less red than irradiated steaks after 5 days of display. Exposure to oxygen by repackaging into oxygen-permeable film increased oxidative rancidity after display. Vacuum-packaging, in combination with irradiation, enables boneless beef steaks to be stored and/or displayed up to 28 …

Kansas Agricultural Experiment Station Research Reports
Irradiation of raw ground beef patties had minimal effects on flavor and aroma of patties after cooking. Oxidative rancidity increased when patties were irradiated in aerobic but not in vacuum packages. Irradiation of vacuum-packaged ground beef patties produced a more stable color. In both packaging types, irradiation significantly reduced microbial growth during storage.

Irradiation did not influence bitter, bloody, burnt, chemical, fat-like, juiciness, liver-like, beef identity, metallic, rancid, sour, sweet, and toughness flavor/textural attributes, beef aroma, or off-odor in precooked ground beef patties. Irradiation slightly increased the animal hair flavor note, but intensity levels were<1 on the 15-point sensory scale. Except for 10% fat non-irradiated controls, reheated precooked patties had a slight sour, ammonia-like, top note. Irradiation at 3.5 kilograys (kGy) increased external redness in vacuum-packaged patties, but not in aerobic packages. Aerobic packaging with or without irradiation decreased external precooked redness. Oxidative rancidity increased when patties were irradiated in aerobic but not in vacuum packages. Reduction of oxygen in vacuum bags extended the shelf life of the precooked ground beef patties, at least in terms of oxidative rancidity. Precooking ground beef patties, irrespective of irradiation or packaging type, posed sensory disadvantages, and improvements to the precooking process are needed before irradiating at low-dose levels is appropriate.

Fate Of Fumonisins In Cattle Fed Contaminated Feed, R.A. Thakur, N. Wallace, J. Scott Smith, Tiruvoor G. Nagaraja
Kansas Agricultural Experiment Station Research Reports
Fumonisins are water-soluble carcinogenic mycotoxins produced by many species of Fusarium molds. Fumonisins occur widely in corn, making them a problem in corn-based feed. Their toxicity has been established in many species. However, their effects on cattle and the potential of carryover to the human diet through beef has not been studied extensively. A 30-day cattle feeding study was conducted by feeding fumonisin-contaminated corn grits dosed at 400 g/g fumonisin B1 (FB1) and 130 g/g fumonisin B2 (FB2) to 3 steers averaging 480 lb. Premortem analysis involved urinalysis; tests for liver functionality; and analysis of the blood, urine, and feces …

Carcass data from one side of 1,149 steers born from 1986 to 1990 were analyzed to develop means for carcass traits and retail product percentage by yield grades. Carcasses from 610 of these steers born from 1988 to 1990 were fabricated to two fat trim levels (.30 and .00 in.), with subcutaneous fat and intermuscular (internal) fat weighed separately. Subcutaneous fat from the primal round, loin, rib, chuck, brisket, and flank in excess of .30 in. plus the kidney knob were considered to constitute an industry "˜hot-fat trim equivalent' (HFTE). Quadratic regression curves were plotted for percent retail product (RP) …

Comparisons Among Crossbred Beef Cattle For Growth And Carcass Traits, K.M. Andries, R.R. Schalles, D.E. Franke, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Data from 5 years of a long-term, rotational crossbreeding project were used to compare breeds for growth and carcass traits. The traits of interest were direct and maternal birth and weaning weights, gain on feed, hot carcass weight, ribeye area, marbling score, and slaughter age. Angus, Brahman, Hereford, Charolais, Simmental, and Gelbvieh breeds were involved. Simmental and Gelbvieh were used as terminal breeds, so maternal effects were not calculated for them. Brahman breeding caused an increased direct birth weight of the calves, but the maternal influence of Brahman decreased birth weight. No difference occurred in maternal weaning weight among the …

Effect Of Increasing Urea Level In Protein Supplements On Performance By Beef Cows Consuming Low-Quality Tallgrass-Prairie Forage, H.H. Köster, R.C. Cochran, E.S. Vanzant, K. C. Olson, Timothy J. Jones, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
Ninety pregnant Angus Hereford cows consuming low-quality, tallgrass-prairie hay were used to evaluate the influence of changing the amount of supplemental degradable intake protein (DIP) derived from urea on body weight and body condition changes, pregnancy rate, and calf performance. Supplemental treatment groups were: 0, 20, and 40% of the supplemental DIP from urea. Supplements were formulated to contain 30% CP . When sufficient DIP was offered to prepartum cows to maximize DOMI, urea could replace up to 40% of the DIP in a high-protein (30%) supplement without causing problems of supplement palatability. However, trends in body weight and condition …

Inheritance Of The "Rat-Tail" Syndrome, R.R. Schalles
Kansas Agricultural Experiment Station Research Reports
A form of congenital hypotrichosis, commonly known as rat-tail, is characterized by the colored hair anywhere on the body being short, curly, malformed, and sometimes sparse and an abnormal tail switch. The "rat-tail" syndrome is controlled by interaction between two loci. Cattle that express this syndrome must have at least one gene for black color and be heterozygous at the other locus involved.

Twelve ruminally fistulated steers were used to evaluate the effect of changing the proportion of supplemental degradable intake protein (DIP) derived from urea on forage intake and digestion. Steers had ad libitum access to a low-quality tallgrass-prairie hay. Supplemental treatment groups were: 1) 0% of the supplemental DIP from urea, 2) 20% of the supplemental DIP from urea, and 3) 40% of the supplemental DIP from urea. Supplements were formulated to contain 30% CP and were fed with prairie hay once daily. Results from this study indicated that urea can replace up to 40% of the supplemental DIP without affecting …
The Influence Of Various Levels Of Supplemental Starch And Degradable Intake Protein On Prairie Hay Intake And Digestion By Beef Steers, R.C. Cochran, E.S. Vanzant, Evan C. Titgemeyer, Timothy J. Jones, K. C. Olson
The Influence Of Various Levels Of Supplemental Starch And Degradable Intake Protein On Prairie Hay Intake And Digestion By Beef Steers, R.C. Cochran, E.S. Vanzant, Evan C. Titgemeyer, Timothy J. Jones, K. C. Olson
Kansas Agricultural Experiment Station Research Reports
A study was conducted to determine the effect of varying the amount of supplemental degradable intake protein (DIP) and starch on prairie hay intake and digestibility. In general, DIP increased forage intake, whereas starch decreased intake. Diet digestibility also improved with increasing DIP; however, the effect of starch on digestion depended on the level of feeding. Digestible dry matter intake (which estimates total energy input) responded dramatically to DIP but not to starch. These results illustrate the positive effect of DIP on forage intake and digestibility; however, supplying additional starch within a DIP level appeared to have minimal effect on …

Kansas Agricultural Experiment Station Research Reports
Ruminal degradation of alfalfa and prairie hay protein was estimated using a proteolytic enzyme from Streptomyces griseus with or without pretreatment with cellulase or a broad spectrum carbohydrase (driselase). Estimates of the undegradable intake protein (UIP) as a percentage of total protein derived from the protease alone were higher than that measured in the animal (i.e., in vivo). Pretreatment of hay samples with cellulase (48 h incubation) or driselase improved the accuracy of UIP predictions compared with those determined using the protease alone.
Effect Of Annual Fire On Tallgrass Prairie Legumes, G. Towne, A.K. Knapp
Effect Of Annual Fire On Tallgrass Prairie Legumes, G. Towne, A.K. Knapp
Kansas Agricultural Experiment Station Research Reports
Total legume density was significantly higher in annually burned prairie (8.0 stems/m2) than in unburned prairie (3.0 stems/ m2). Densities of six species were higher (P<.05) in burned than in unburned prairie, whereas only one legume species decreased from annual fire. Total legume biomass did not differ between burned (11.3 g/m2) and unburned prairie (10.5 g/m2). Most legume species either are favored by fire or are fire tolerant, and their persistence in annually burned grassland suggests that they may play an important role in the nitrogen budget of tallgrass prairie.

Results at Kansas State University from over 200 laboratory-scale trials and 28 farm-scale trials showed that bacterial inoculants consistently improved preservation efficiency and nutritive value of the ensiled material. In contrast, anhydrous ammonia or urea decreased dry matter recovery and production per ton of crop ensiled. Economic analysis also favored the use of bacterial inoculants over nonprotein nitrogen additives. Research conducted using corn, sorghum, and alfalfa silages showed that sealing the exposed surface dramatically reduced top spoilage losses in bunker, trench, or stack silos.

Effect Of Grain Content On The Nutritive Value Of Whole-Plant Grain Sorghum Silage, B.S. Dalke, R.N. Jr. Sonon, D.L. Holthaus, K.K. Bolsen, Matthew A. Young
Kansas Agricultural Experiment Station Research Reports
This experiment was conducted to determine the effect of grain content on the nutritive value of whole-plant grain sorghum silage. Silage dry matter (DM), organic matter (OM), and crude protein (CP) contents increased with increasing levels of grain in the reconstituted, whole-plant silages, whereas neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents decreased as the level of grain increased from 0 to 48%. When fed to sheep (used as a model), voluntary DM intake and DM and OM digestibilities increased in a linear manner, whereas ADF digestibility decreased with increasing level of grain. Crude protein and NDF digestibilities …

Agronomic And Silage Quality Traits Of Winter Cereals, M.K. Siefers, G.L. Huck, J.E. Turner, J.S. Pendergraft, K.K. Bolsen, Matthew A. Young
Kansas Agricultural Experiment Station Research Reports
Agronomic and silage quality traits were examined for 12 winter cereals harvested at two stages of maturity. Forage dry matter (DM) yields were higher at the mid-dough than the early-heading stage. Post 90 barley had the highest whole-plant DM yield at the early-heading stage, and Presto triticale had the highest yield at the mid-dough stage. Newton wheat had the lowest whole-plant DM yield at both stages of maturity. The first cutting of all varieties originally was intended to be at the late-boot stage, but harvest was delayed by frequent rainfall and wet soils in May, and field-wilting conditions were less …

Effect Of Bacterial Inoculants On The Fermentation Of Alfalfa Silages, K.K. Bolsen, D.R. Bonilla, R.A. Hart-Thakur, Matthew A. Young
Kansas Agricultural Experiment Station Research Reports
The efficacy of 13 commercial bacterial silage inoculants was evaluated on 3rd and 4th cutting alfalfa. All inoculants supplied at least 100,000 colony-forming units (cfu) of lactic acid bacteria (LAB) per gram of ensiled crop, and each inoculant increased the rate and efficiency of the ensiling process. Inoculated alfalfa silages had lower pH values; higher lactic acid contents; and lower acetic acid, ethanol, and ammonia-nitrogen contents than control (untreated) silages. The addition of dextrose (fermentable substrate) in combination with a bacterial inoculant improved the quality of the fermentation phase in both cuttings of alfalfa.

Two hundred-sixteen Angus and Angus-cross steer calves (690 lb) were used in a 129- day finishing study to evaluate different implant strategies, including an experimental new implant for feedlot cattle that contains 28 mg of estradiol benzoate and 200 mg of trenbolone acetate (EBTBA). Treatments were 1) nonimplanted control, 2) implanted and reimplanted with Synovex-Sfi, 3) single initial implant with EBTBA, 4) single initial implant with Revalor-Sfi, 5) implanted with Synovex-S and reimplanted with EBTBA, and 6) implanted and reimplanted with EBTBA. Initial implants and reimplants were administered on day 0 and 63, respectively. All implant treatments increased feed intake, …

Seventy-two mixed breed steers (679 lb avg BW) grazing smooth bromegrass pastures for 112 days were fed 2.2 lb/day of either a control supplement (PC) or one containing .075 lb/day of magnesium-mica (PMM). Following the grazing period, steers were placed in a feedlot with pasture groups split such that two of the groups fed each pasture supplement were fed a control supplement (FC) and two groups were fed a supplement containing 10% magnesium-mica (FMM). Steers fed PMM tended to gain faster than those fed PC during the pasture phase (2.41 vs. 2.32 lb/day). Steers fed PMM had higher dressing percentage …

Fusobacterium necrophorum was the predominant bacterial isolate from liver abscesses of feedlot cattle fed with or without tylosin. The major difference in the bacterial flora of liver abscesses between cattle groups was the higher incidence of Actinomyces pyogenes in the tylosin-fed cattle. Because the minimum inhibitory concentration of tylosin was not different between bacterial isolates from cattle in the two treatments, we concluded that continuous feeding of tylosin does not induce resistance. The source of A. pyogenes infection and significance of A. pyogenes interaction with F. necrophorum in tylosin-fed cattle are not known.
