  • The use of Bovine Somatotropin (BST) in dairy cattle
    Estrada, J.; Shirley, J.E. (Kansas Agricultural Experiment Station, 1989)
    We all have heard about the use of BST in lactating dairy cattle during the last 6 to 8 years, but what is BST? Bovine somatotropin is another dairy management tool developed to improve the efficiency and reduce the cost ...
  • Use of extruded soy flour in milk replacers for calves
    Dawson, D.P.; Morrill, J.L.; Reddy, P.G.; Behnke, K.C. (Kansas Agricultural Experiment Station, 1987)
    Oil-extracted, desolveritized soy flour without additional heat treatment was used to prepare protein supplements for calf milk replacers by extrusion processing. Various combinations of temperature, moisture, calcium ...
  • Use of GnRH and PGF for synchronized ovulation and fixed-time inseminations
    Stevenson, J.S.; Kobayashi, Y. (Kansas Agricultural Experiment Station, 1994)
    Holstein cows and virgin heifers were treated with GnRH and PGF in a novel 2a ovulation synchronization protocol, which involves one fixed-time insemination. One injection of GnRH is given on a Monday morning, followed ...
  • Use of milk progesterone and PGF[subscript]2alpha in a scheduled insemination program
    Stevenson, J. S.; Pursley, J. R. (Kansas Agricultural Experiment Station, 1993)
    Holstein cows milked twice daily were assigned to be inseminated at their first detected estrus (control) after 42 days in milk or received PGFza (PG) after 42 days, if they had a high milk progesterone (P4) test on ...
  • The use of somatic cell counts to identify cows with subclinical mastitis at calving
    Sargeant, J. M.; Shirley, J. E.; Pulkrabek, B. J.; Scheffel, M. E.; Park, A. F. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1999)
    The dynamics of somatic cell counts during the first 10 days in milk were compared among udder quarters of cows with intra-mammary infection at the time of calving and those with no infection present. The study group ...
  • Using AI calving-ease bulls on replacement heifers
    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 ...
  • Using the ovsynch protocol for prompt re-insemination of cows diagnosed open at pregnancy checks
    Stevenson, J. 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 ...
  • Using the somatic cell count report
    Dunham, J.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 ...
  • Using vaginal temperature to evaluate heat stress in dairy cattle
    Brouk, M.J.; Cvetkovic, B.; Smith, J.F.; Harner, J.P. (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, ...
  • Utilization of near infrared reflectance for the determination of fat, moisture, and protein in cheddar cheese
    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 ...
  • Variations in the ovsynch protocol alter pregnancy rates in lactating dairy cows
    Portaluppi, M.A.; Stevenson, J.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 ...
  • Various estrus-synchronization programs for heifers
    Stevenson, J. 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 ...
  • Vitamin E requirements of dairy calves
    Reddy, P.G.; Morrill, J.L.; Minocha, H.C.; Frey, R.A.; Stevenson, J.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 ...
  • Waste management in the production dairy indistry
    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 ...
  • Waste management: regulations and problems in Kansas
    Harner, J.P.; Murphy, J.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 ...
  • Water consumption of an evaporative cooling system in the midwest
    Harner, Joe; 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 ...
  • Water removal from raw milk at the point of production
    Cox, I.; Dingeldein, H.; Schmidt, K. (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, J.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 ...
  • Why do dairy cows have reproductive problems? How can we solve those reproductive problems?
    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, J.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 ...
