  • A rapid method of analysis of corn grain for dairy cattle
    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 ...
  • Reproductive research in dairy cattle at KSU
    Stevenson, J.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 ...
  • Reproductive status of Kansas dairy herds
    Call, E.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 ...
  • 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 ...
  • 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 ...
  • Whole-plant grain sorghum and inoculated corn silages in mid-lactation dairy cow diets
    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, ...
