  • Natural mating of estrus-synchronized heifers and indicators of bull fertility
    Pruitt, R.J.; Corah, L.R.; Simms, D.D.; Spire, M.F. (Kansas State University. Agricultural Experiment Station, 1982)
    In six trials involving 486 heifers and 23 bulls, we studied factors affecting pregnancy rates of estrus-synchronized heifers mated naturally and evaluated indicators of bull fertility. Heavier heifers and those in fleshier ...
  • Near infrared spectroscopy as a potential method to detect bovine respiratory disease
    Fox, J.T.; Spire, M.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Bovine respiratory disease continues to be the leading cause of illness and death loss from weaning through finishing. There is no objective method to evaluate a live animal’s severity of sickness or their response to ...
  • Performance and carcass characteristics of finishing steers fed dried, full-fat corn germ
    Drouillard, J.S.; Kessen, T.J.; Sulpizio, M.J.; Spire, M.F.; Ethington, R.T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    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 chara ...
  • Revaccination of recently processed cattle
    Spire, M.F.; Riley, J.G.; Edwards, A.J. (Kansas State University. Agricultural Experiment Station, 1983)
    Two trials were conducted to evaluate the effectiveness of revaccinating recently processed cattle with modified live IBR and BVD vaccine. Revaccination decreased total illness 24 to 26%. A significant reduction in clinically ...
  • Splay-foot in cattle
    Schalles, R.R.; Markham, R.W.; Leipold, H.W.; Spire, M.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Angular limb deformity, observed in several breeds of cattle, results in a knock-kneed and splay-footed condition in the front legs. This study shows that angular limb deformity is a congenital structural defect, inherited ...
  • Trailer-mounted RFID reader scans EID tags during cattle shipments
    Barnhardt, B.B.; Bryant, A.M.; Epp, M.P.; Spire, M.F.; Blasi, D.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    One of the challenges regarding implementation of a national animal identification system is the logistics of reading and reporting EID (electronic identification) tag numbers as cattle move through the production cycle. ...
  • Use of Cystorelin® and artificial insemination in repeat-breeding beef heifers after estrous synchronization
    Holz, J.P.; Houghton, P.L.; Spire, M.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    Gonadotropin-releasing hormone (GnRH) was administered to a group of 13- to 14- month-old Angus and Angus crossbred repeat-breeding heifers at the time of the second or third artificial insemination to determine ...
  • Use of infrared thermography to evaluate differences in mean body surface temperature and radiant heat loss in growing pigs
    Loughmiller, J.A.; Spire, M.F.; Tokach, M.D.; Dritz, S.S.; Nelssen, J.L.; Goodband, R.D.; Hogge, S.B.; James, B.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Eighty barrows were used in two experiments to determine the relationship between feed intake or dietary energy concentration and mean body surface temperature (MBST) and mean body surface radiant heat loss (MBSL) as ...
  • Utilizing infrared thermography to predict pork quality
    Lawrence, T.E.; Spire, M.F.; Dikeman, M.E.; Hunt, M.C.; Hogge, S.B.; James, B.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Three experiments using 63 pigs were conducted to determine if infrared thermography could segregate pigs based on subsequent pork quality. Pigs were subjectively classified as either “hot” or “normal” based on infrared ...
