  • Heikes, K.A. (Kansas Agricultural Experiment Station, 1986)
    For maximal genetic progress in a dairy, proven AI sires should be selected to use on replacement heifers. To minimize problems at calving, these sires should be selected from bulls that are breed average or better for ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Using the Ovsynch protocol to prepare cows for re-insemination proved to be very effective. Its use guarantees that all cows found open at pregnancy diagnosis are reinseminated promptly within 10 days, and the average ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1996)
    High-producing dairy herds can consistently average a somatic cell count (SCC) <200,000. Herds with consistently higher averages can decrease SCC and realize higher profits. The SCC report discloses the pitfalls that ...
  • Cvetkovic, B.; Smith, J.F.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2005)
    A rise in body temperature is a signal that heat stress has exceeded the heat-exchange capacity of the dairy cow. Previous studies have shown a strong positive correlation between vaginal temperature and respiration rate, ...
  • Zink, G.S.; Jeon, I.J.; Harbers, L.H. (Kansas Agricultural Experiment Station, 1989)
    Near infrared reflectance spectroscopy (NIRS) was used to develop calibration equations for the rapid determination of moisture, protein, and fat in Cheddar cheese. Most mean values from NIRS data had lower standard ...
  • Portaluppi, M.A.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Initiation of the Ovsynch protocol at random stages of the estrous cycle produces differences in synchronization and pregnancy rates. Use of two injections of PGF2α administered 14 days apart, with the second ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Various programs of estrus synchronization have been tested during the last 6 years to determine the least costly and most efficacious for dairy heifer replacements. Four systems were tested: 1) a modified Ovsynch treatment ...
  • Reddy, P.G.; Morrill, J.L.; Minocha, H.C.; Frey, R.A.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1986)
    Thirty-two Holstein heifer calves receiving conventional rations were supplemented with 0 (control), 125, 250, or 500 IU vitamin E/calf/day. The objective was to determine the optimum requirement based on their ...
  • Fulhage, C. (Kansas Agricultural Experiment Station, 1992)
    The impact of environmental regulation on livestock production enterprises is, inevitably, an increase in production costs. Producers should recognize that these are the costs of doing business and will probably have ...
  • Harner, Joseph P.; Murphy, James P. (Kansas Agricultural Experiment Station, 1992)
    The dairy industry is receiving greater pressure to reduce its potential pollution to the environment. As the demand grows for cleaner streams, dairy operations will need to reduce and control the nutrient and sediment ...
  • Harner, Joseph P.; John, Smith (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Water meters were installed on the evaporative cooling system of a long, low-profile, cross-ventilated dairy in the upper Midwest. The evaporative pad along the west side measured 10 by 350 ft. The water usage per unit ...
  • Cox, I.; Dingeldein, H.; Schmidt, Karen A. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Milk processing plants are becoming fewer in number and larger in size. As a result, the distance the raw milk is transported from the point of production to the processing site increases. Because the major component ...
  • Bolsen, K.K.; Shirley, John E.; Laytimi, A.; Dickerson, J. (Kansas Agricultural Experiment Station, 1989)
    Whole-plant grain sorghum silage and Silo-Best-Soluble inoculated and uninoculated control corn silages were compared in complete-mixed diets for mid-lactation dairy cows. Cows fed the inoculated corn silage yielded .6 ...
  • Britt, J.S. (Kansas Agricultural Experiment Station, 1989)
    Except for very low producing herds, management of reproduction does not seem to have much effect on the herd's level of production. To counter this statement, we must ask the question: "If they did not manage reproduction, ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station and Cooperative Extension Service., 1998)
    Management of the estrous cycle is now more practical than it was a decade ago because of our understanding of follicular waves. With availability of three gonadotropin-releasing hormone (GnRH) products and two ...
