  • Schalles, R.R.; Spire, M.; Clarke, C. (Kansas State University. Agricultural Experiment Station, 1983)
    Heavy milking cows took longer to respond to estrus synchronization than light milking cows. There was no difference in response time between cows treated with Estrumate and Lutalyse. Cow weight, height or condition had ...
  • Anglin, C.O.; Epp, M.P.; Derstein, R.D.; Barnhardt, B.B.; Blasi, Dale A.; Olson, K. C.; Reinhardt, Christopher D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Beef stocker operators are margin-operators, and rising feed costs force them to consider alternative feeding strategies to reduce production costs. Limit-feeding is a management technique that has positive implications ...
  • Reinhardt, Christopher D.; Lee, Tiffany L.; Thomson, Daniel U.; Mamedova, Laman K.; Bradford, Barry J. (2013)
    Background: During nutritional stress, reduced intake may reduce the efficacy of anabolic implants. This study was conducted to evaluate basic cellular responses to a growth promotant implant at two intake levels. Methods: ...
  • Hoffman, D.P.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    The suckling interaction between a cow and her calf is one of the factors that maintains a cow in postpartum anestrus (the period between calving and the beginning of first estrous cycle). Anestrus continues if the cow ...
  • Hoffman, D.P.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    The suckling interaction between a cow and her calf is one of the factors that maintains a cow in postpartum anestrus (the period between calving and the beginning of first estrous cycle). Anestrus continues if the cow ...
  • Allee, G.L.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1977)
    Gestating Yorkshire sows and gilts were randomly assigned to two dietary treatments immediately after a 25-day breeding season until females were brought to the farrowing house between 105-110th day of gestation. Sows and ...
  • Arnett, A.M.; Daniel, M.J.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Marbling continues to be a major factor affecting profitability for beef producers, processors, retailers, and restaurateurs. However, feeding animals to ‘fatten’ is quite inefficient, requiring about 2.25 times more energy ...
  • Pruitt, R.; Fleck, A.; Smith, E.F.; Corah, L.; Owensby, Clenton E. (Kansas State University. Agricultural Experiment Station, 1978)
    Reimplanting Ralgro in mid-July after implanting in late April did not improve daily summer gains compared to a single implant.
  • Simms, D.; Langemeier, Michael R.; Utter, S.; Fike, G.; Bandyk, C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    A survey of production levels and management practices of 205 cow herds representing over 26,000 cows in Kansas was conducted in 1991. These operations were located throughout Kansas except for the Northwest corner. ...
  • Corah, L.; Schwartz, F.; Brazle, F.; Orwig, T.; Francis, G. (Kansas State University. Agricultural Experiment Station, 1977)
    To encourage greater use of implants in beef cattle industry in Kansas, 62 implant demonstrations were conducted in 31 different counties in Kansas. 1,402 implanted suckling calves gained an average of 15.1 pounds more ...
  • Aubel, C.E. (Kansas Agricultural Experiment Station, 1946)
    In order to produce swine profitably, it is necessary to make use of forage crops. This practice will not only save grain, but will contribute to the general health of the swine themselves. Since the country has been at ...
  • Medina-Britos, M.A.; Richardson, A.M.; Lamb, G.C.; Hensley, B.A.; Marple, T.J.; Stevenson, Jeffrey S.; Johnson, Sandra K. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    A study was conducted in 609 beef cows to determine whether or not estrus might be resynchronized in previously inseminated beef cows to accommodate a second artificial insemination (AI) early in the breeding season. ...
  • Portaluppi, M.A.; Tenhouse, D.E.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Our objectives were to determine various factors influencing upfront single and multiple ovulation in response to GnRH in a timed arti-ficial insemination (TAI) protocol and subse-quent fertility after altering timing of ...
  • Martel, C.A.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Lactating dairy cows and replacement virgin heifers of unknown pregnancy status were treated with either gonadotropin-releasing hormone (GnRH) or saline to initiate a resynchronization program that was continued 7 days ...
  • Tiffany, S.M.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    We compared outcomes of two protocols used to resynchronize estrus and ovulation in dairy females after found open at pregnancy checks. Replacement heifers and lactating cows in which AI occurred 41 ± 1 day earlier ...
  • Spire, M.F.; Riley, Jack 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 ...
