  • Smith, J.F.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Feed intake is the single most critical factor of dairy production, and performance of dairy cattle can be enhanced or hindered by environmental factors that affect it. These environmental factors can by divided ...
  • Stevenson, Jeffrey S.; Schmidt, M.K.; Call, Edward P. (Kansas Agricultural Experiment Station, 1984)
    Stage of the estrous cycle, time of insemination, and season of the year were examined for their influence on estrus and fertility of 223 Holstein heifers after prostaglandin F2α(PGF). Heifers given PGF early in the ...
  • Schmidt, Karen A.; Stupar, J.; Shirley, John E.; Adapa, S.; Sukup, D. (Kansas Agricultural Experiment Station, 1996)
    The value of titratable acidity (TA) as an indicator of raw milk quality has been challenged recently, because milk is refrigerated within minutes after it leaves the cow until it reaches the consumer. Also, high milk ...
  • Dunham, J.R. (Kansas Agricultural Experiment Station, 1986)
    Feed additives are ration ingredients used in relatively small amounts to fortify certain nutrients or to affect a specific physiological function. The decision to include any additive should be based upon the economic ...
  • Dunham, J.R. (Kansas Agricultural Experiment Station, 1987)
    Feeding and managing dairy cows during the prepartum and early lactation periods have more effect on total lactation yields than all other factors. It is during this time that the pattern of milk production is established ...
  • Schingoethe, D. J. (Kansas Agricultural Experiment Station, 1993)
    Dairy cows must consume a lot of feed to achieve the levels of production expected today; however, the nutrient needs of dairy cows vary immensely between the dry period and peak lactation. Requirements for the former ...
  • Richardson, A.M.; Hensley, B.A.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Our objective was to determine fertility of heifers after synchronization of estrus using PGF2", preceded by progesterone, GnRH, or both. Dairy heifers (n = 246) were assigned randomly to three treatments: 1) 50 :g ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1986)
    Prostaglandin F2α (PGF) and gonadotropin-releasing hormone (GnRH) have provided new dimensions in resolving certain reproductive maladies. Effective when used properly, these hormones have the advantage of mimicking the ...
  • Morrill, J.L.; Laster, J.F.; Morrill, J.M.; Feyerherm, A.M. (Kansas Agricultural Experiment Station, 1992)
    Holstein steer calves (n = 96) were on experiment from 8 to 18 wk of age. Control calves were fed a diet in which all supplemental protein was from soybean meal; in the experimental diet, part of the soybean meal ...
  • Pulley, Stephanie L.; Hill, Scott L.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2013)
    Two experiments were conducted to assess pregnancy outcomes after a 5-day Ovsynch-56 Resynch (RES; gonadotropin-releasing hormone injection 5 days before [GnRH-1; d 0] and 56 hours (GnRH-2) after PGF2α [PG] injections ...
  • Van Metre, D.C.; St. Jean, G.; Vestweber, J. (Kansas Agricultural Experiment Station, 1996)
    Cattle that become recumbent (unable to get up) as the result of calving difficulty, low blood calcium, traumatic injuries, or other disorders are prone to develop subsequent pressure damage of muscles, nerves, and ...
  • Harner, Joseph P.; Murphy, James P. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Flushing systems that collect and transport manure are utilized in dairy operations. The sanitation attainable and reduced labor requirements can make flushing a desirable option. Designed flush systems utilize a flush ...
  • Harner, Joseph P.; Strahm, T.D.; Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Sand can be handled successfully either in a scrape or flush system by developing handling systems that allow for the sand-laden manure to settle prior to the effluent entering a lagoon. The abrasiveness and density ...
  • Harbers, L.H. (Kansas Agricultural Experiment Station, 1986)
    It has been over 15 years since an analytical instrument was developed that could rapidly determine the concentration of organic compounds from the spectra produced by the bonding between carbon and certain molecules. ...
  • Bickert, W.G.; Smith, J.F. (Kansas Agricultural Experiment Station and Cooperative Extension Service., 1998)
    Proper design, construction, and care of freestalls are essential to cows using the stalls and realizing their potential benefits for comfort and health. Freestall dimensions depend upon particular designs and are ...
  • Smith, J. F.; Jones, G. A.; Harner, Joseph P. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    The design and management of freestall 4) air or vision. facilities are critical in maintaining cow comfort and high milk production. Dairy produc- Lunge Space ers should be conscious of the factors affecting cow comfort ...
  • Olson, Jerry D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    The post-calving period is a critical time in a cow’s life. The first few weeks post-calving pose the highest risk period for a number of diseases including milk fever, mastitis, metritis, pneumonia, retained fetal ...
  • Stevenson, Jeffrey S.; Stewart, R.E.; Call, Edward P. (Kansas Agricultural Experiment Station, 1987)
