  • Drip cooling of lactating sows
    Nichols, D.A.; Murphy, J.P.; Vic Robbins, F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Twenty eight sows and gilts were used to evaluate the value of drip sprinkling to reduce heat stress in lactating sows. Respiration rates for sprinkled sows were significantly lower than those of controls. Daily feed intake ...
  • Drought-stressed, irrigated, and additive-treated corn silages for growing cattle
    Bolsen, K.; Ilg, H.; Smith, R.; Hoover, J.; Axe, D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1985)
    Cattle fed drought-stressed corn silage gained about 10% slower but were just as efficient as cattle fed irrigated corn silage. Because the irrigated corn out yielded the drought corn (17.4 VS. 8.2 tons per acre), the ...
  • Dry aging: an old process revisited
    Campbell, R.E.; Hunt, M.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    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. ...
  • Dry cow management program
    Smith, J.F. (Kansas Agricultural Experiment Station, 1987)
    Dry cows do not require the intensive daily management of cows in early lactation, but the handling of mastitis treatments, feeding regimen, and grouping are of utmost importance in determining how the cows will perform ...
  • Dry vs. wet ad libitum feeding of finishing swine
    Hines, R.H.; Vargas Vargas, J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1985)
    Two hundred finishing pigs were used to evaluate wet vs. dryad libitum feeding. Growth rate of finishing pigs was significantly improved (5%) by wet feeding. Feed utilization was improved 4.5% by wet feeding. Dry feeder ...
  • Drylot receiving program vs pasture conditioning with Micotil® metaphylaxis for grazing stocker calves
    Paisley, S.I.; Falkner, T.R.; Brazle, F.K.; Stokka, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Three stocker cattle field studies were conducted comparing a traditional 4- to 5-week drylot receiving program with injectable antibiotics administered on a pull-and-treat basis versus a pasture-based conditioning ...
  • Duration of plasma oxytetracycline levels in neonatal pigs
    Schoneweis, D.; Hummels, S.; Schulteis, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1981)
    Samples from neonatal pigs were evaluated to determine the persistence of plasma oxytetracycline after injecting LA 200®. Significant (minimum of .2 mcg/ml) amounts of oxytetracycline were found in all samples 96 hours ...
  • Dust bags for fly control under range conditions
    Schalles, R.R.; Pitts, C.W. Jr.; McKee, M.; Evans, J. (Kansas State University. Agricultural Experiment Station, 1972)
    Cattlemen have traditionally used various methods to control horn flies and, more recently, face flies. Many methods used require various amounts of labor and handling of cattle. Most recent efforts have stressed minimum ...
  • Dwarfism in beef cattle
    Smith, W.H.; Holland, L.A. (Kansas Agricultural Experiment Station, 1954)
    During recent years there have been several scientific and numerous breeders' reports on dwarfism in the Angus, Hereford, and Shorthorn breeds of beef cattle. These have described what appear to be several different ...
  • Early detection of problem implants using infrared thermography
    Spire, M.F.; Galland, J.C.; Drouillard, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    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, ...
  • Early lactation somatic cell count should be low
    Dunham, J.R. (Kansas Agricultural Experiment Station, 1987)
    Cows and heifers in milk for fewer than 50 days, as shown on the DHIA Somatic Cell Count report, should have a lower average Somatic Cell Count than cows in milk for more than 300 days, if the dry cow mastitis treatment ...
  • Early postpartum hormonal therapy improves fertility of dairy cows
    Stevenson, J.S.; BenMrad, M. (Kansas Agricultural Experiment Station, 1985)
    A study of 234 Holstein cows was conducted to determine if hormonal treatments of gonadotropin-releasing hormone (GnRH or Cystorelin®) and(or) prostaglandin F2a (PGF or Lutalyse®) given early after calving would ...
  • Early postpartum luteal function after treatment with progestin and(or) gonadotropin-releasing hormone in dairy cattle
    Mee, M.O.; Stevenson, J.S. (Kansas Agricultural Experiment Station, 1988)
    Progestin (Norgestomet®) and(or) repeated low-dose infusions of GnRH (Cystorelin@) influenced the lifespan of the first corpus luteum after an induced ovulation. Holstein cows (n=32) were assigned at calving to four ...
  • Early weaning and creep feeding calves in drylot
    Kimple, K.; McKee, M.; Fink, G.; Conway, K. (Kansas State University. Agricultural Experiment Station, 1977)
    Performances of 125 commercial Hereford-cross and percentage Simmental calves were evaluated by comparing early weaning at 50 days of age (+25), nursing calves receiving a creep in drylot, and calves nursing in drylot ...
  • Eating and cooking loss characteristics of electrically stimulated and hot boned bull inside round muscle chilled at different rates
    Shivas, S.D.; Kastner, C.L.; Dikeman, M; Hunt, M.C.; Kropf, D.H. (Kansas State University. Agricultural Experiment Station, 1983)
    We found steaks cut from inside rounds (chilled fast or slow) of electrically stimulated and hot boned bull carcasses, to be similar to conventionally processed steaks in taste panel, shear force and cooking loss characteristics.
  • Ecological genomics: making the leap from model systems in the lab to native populations in the field.
    Travers, Steven E.; Smith, Melinda D.; Bai, Jianfa; Hulbert, Scot H.; Leach, Jan E.; Schnable, Patrick S.; Knapp, Alan K.; Milliken, George A.; Fay, Philip A.; Saleh, Amgad; Garrett, Karen A. (2007)
    Recent reviews have emphasized the need to incorporate genomics into ecological field studies to further understand how species respond to changing environmental conditions. Genomic tools, such as cDNA (complementary DNA) ...
  • Economic adjustments to groundwater depletion in the High Plains: do water-saving irrigation systems save water?
    Peterson, Jeffrey M.; Ding, Ya (2005)
    A common policy prescription for conserving irrigation water is to promote more efficient or “water-saving” irrigation technologies. We develop a risk programming model to quantify the effect of irrigation efficiency on ...
