  • Morrill, J.L. (Kansas Agricultural Experiment Station, 1994)
    On many dairy farms, improvement is needed in raising replacement heifers, especially in providing proper nutrition and management to allow for freshening at 23 to 24 mo of age at a desirable size. With larger herds, there ...
  • Garcia, G.; Malvetti, R.; Harbers, L.H. (Kansas Agricultural Experiment Station, 1989)
    Calibration equations for near infrared reflectance spectroscopy (NIRS) have been either purchased from the manufacturer or developed in the laboratory. Comparative analysis with standard laboratory procedures indicate ...
  • Holthaus, D.L.; Young, Matthew A.; Pfaff, L.; Brent, B.E.; Boyer, John E.; Bolsen, K.K. (Kansas Agricultural Experiment Station, 1994)
    Alfalfa silages were made in pilot- and farm-scale silos, and five sealing treatments were compared. After 90 days, sealing dramatically reduced dry matter (DM) losses at the 5 and 10 inch depths in the farm silos and ...
  • Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    For many years, fiber in dairy rations was measured and expressed as crude fiber. More recently acid detergent fiber (ADF) and neutral detergent fiber (NDF) have been used. The crude fiber (CF) determination uses acid ...
  • Roberts, H. A. (Kansas Agricultural Experiment Station, 1993)
    Flavor control in market milk begins on the farm and continues through the processing plant and into the home of the consumer. Flavor control is directly or indirectly related to the health of the cow, the feeding of ...
  • Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Raw milk quality is important to the processor for many reasons, this quality can be assessed by several different tests. Quality tests are used to ensure that the raw milk meets legal USDA standards as well as some of ...
  • Meyer, M. J.; Everett, R.W.; Van Amburgh, M.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    The primary advantages of reducing age at first calving (AFC) include reducing rearing costs as well as reducing time in which the heifer is only a capital drain on farm resources. The primary disadvantage of reducing AFC ...
  • Smith, J.F.; Stokka, Gerald L.; Scoby, R.K; Van Anne, T.; Shirley, John E. (Kansas Agricultural Experiment Station, 1996)
    Bovine leukosis virus (BLV) is a cancerous condition of tissues in which lymph nodes and lymphocytes are affected. Infected cattle may be identified by testing blood sera for BLV antibodies using the agar gel ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2012)
    The objective was to quantify the reinsemination intervals of lactating dairy cows that were either inseminated at estrus or received a timed AI (TAI) at first service. Cows in Experiment 1 were enrolled in a TAI program ...
  • Ferdinand, E.E.; Meyer, M. J.; Park, A.F.; VanBaale, M. J.; Titgemeyer, Evan C.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Eight Holstein cows were used to determine the relationship among milk urea nitrogen (MUN), plasma urea nitrogen (PUN), and feeding time. We first established that MUN concentrations were similar in concentration among ...
  • Call, Edward P.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1984)
    Reproductive parameters were evaluated in 5,480 Holstein herds involving 335,673 cows to determine the reported negative genetic effect of production on reproduction. While higher producing herds had a slight decline in ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1985)
    The rate of spontaneous recovery from subclinical mastitis was evaluated in 56 Kansas. DHI herds participating in the Somatic Cell Count (SCC) program. Herds were classified as low (>300,000) or high (>600,000) based on ...
  • Shirley, John E.; Morrill, J.L.; Carinder, W.H. (Kansas Agricultural Experiment Station, 1987)
    Soybeans interseeded with grain sorghum and harvested as a mixed forage silage crop can be used successfully as a feed for growing dairy heifers. However, daily gain is greater when grain sorghum silage plus alfalfa hay ...
  • Greene, G. L. (Kansas Agricultural Experiment Station, 1991)
    After release of fly parasites in Kansas dairies during 1991, parasitism increased from May to late June then dropped in July. The parasite released was Spalangea nigroaenea of Kansas origin to assure its adaption to ...
  • Smith, J. F.; Harner, Joseph P.; Armstrong, D. V.; Gamroth, M. J.; Meyer, M. J.; Boomer, G.; Bethard, G.; Putnam, D.; Brouk, Michael J. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Relocating or expanding a dairy facility requires a tremendous amount of time and planning. Owners or managers of dairies will go through a number of steps including: 1) developing a business plan; 2) choosing a design ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1986)
    Records are the backbone of any breeding program. Artificial insemination (AI) is essential to maximizing genetic gain and minimizing calving problems and breeding costs. In addition, AI allows controlled calving - calving ...
  • Avery, T.B. (Kansas Agricultural Experiment Station, 1986)
    Common disease causing agents are identified and a sample replacement heifer health program is presented. Written objectives are useful for evaluation of heifer rearing.
  • Call, Edward P.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1985)
    An analysis of 635 Kansas Holstein herds with 41,426 cows indicated that the negative genetic antagonism between production and reproduction can be overcome with good management practices. As rolling herd average increased, ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1989)
    Research in reproductive physiology and breeding management of dairy cattle at Kansas State University has the following objectives: 1) to better understand those factors that influence the reestablishment of ovarian ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1989)
    There has been no appreciable change in the reproduction status of Kansas dairy herds over the last 25 yr. For example, the average calving interval was 398 days in 1965 and 405 days in 1988. Analysis of other measures ...
