  • Call, Edward P. (Kansas Agricultural Experiment Station, 2012-09-20)
    The rate of involution of the bovine uterus is remarkable. By 20 days after calving, tissue sloughing and hemorrhaging have ceased, and the size of the uterus has been reduced by more than 80%. By 40 days, the uterus has ...
  • Pruiett, S.D.; Morrill, J.L.; Blecha, Frank; Higgins, James J.; Anderson, N.V.; Reddy, P.G. (Kansas Agricultural Experiment Station, 2012-09-07)
    Calves were bottle-fed milk replacers at 10% of weekly adjusted body weight for 8 wk. Treatments were 1) no supplements (control), 2) .16 oz vitamin C, or 3) .16 oz vitamin C plus 125 IU/lb vitamin E. Lymphocytes and ...
  • Stevenson, Jeffrey S.; Mee, M.O.; Scoby, R.K.; Folman, Y. (Kansas Agricultural Experiment Station, 2012-09-07)
    We demonstrated that gonadotropin-releasing hormone (GnRH or Cystorelin®) failed to improve pregnancy rates at the first service. When GnRH injection and insemination are both carried out either in early or late estrus ...
  • Lagombra, Gregorio Garcia; Malvetti, R.; Harbers, L.H. (Kansas Agricultural Experiment Station, 2012-09-07)
    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 ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 2012-09-07)
    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, 2012-09-07)
    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 ...
  • Estrada, J.; Shirley, John E. (Kansas Agricultural Experiment Station, 2012-09-20)
    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 ...
  • Zink, G.S.; Jeon, I.J.; Harbers, L.H. (Kansas Agricultural Experiment Station, 2012-09-07)
    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 ...
  • Bolsen, K.K.; Shirley, John E.; Laytimi, A.; Dickerson, J. (Kansas Agricultural Experiment Station, 2012-09-07)
    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, 2012-09-07)
    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, ...
