  • Dunham, James R. (Kansas Agricultural Experiment Station, 1991)
    Heifer feeding and management programs have a great impact on the efficiency of the future dairy herd. Dairies that feed and manage heifers for calving at about 24 mo of age are optimizing milk production, feed cost ...
  • Rezac, D.J.; Grigsby, K.N.; Bradford, Barry J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    A novel diet formulation strategy incorporating wet corn gluten feed at 47% of diet dry matter was evaluated in late-lactation cows. Diets were formulated for similar protein and energy concentrations with dramatic ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1993)
    Wetter than normal growing and harvesting conditions have resulted in a short supply of high quality alfalfa. Because forage quality affects milk production in early lactation cows, dairy farmers are encouraged to ...
  • Lamb, G.C.; Hoffman, D.P.; Kobayashi, Y.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1996)
    The objective of this study was to examine changes in ovarian steroids in relation to the onset of first standing estrus detected by pressure-sensitive rump-mounted devices (ABS HeatWatch® [HW]). Twenty Holstein ...
  • Bradford, Barry J. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2012)
    In the past, efforts to improve the transition to lactation have focused largely on preventing infections and maximizing energy intake in transition cows, and these issues have generally been treated independently. New ...
  • Roberts, H.A. (Kansas Agricultural Experiment Station, 1987)
    Milk with high solids-not-fat is valuable to the consumer for its flavor and nutritional value and to the manufacturer of milk products, especially relating to cheese yield. Solids-not-fat consists of all solids in milk ...
  • Cropp, Bob (Kansas Agricultural Experiment Station, 1996)
    Milk pricing will continue to change. Clearly, the dairy industry will continue the trend toward MCP. The federal dairy price support program will terminate at the end of 1999. Changes will occur in federal order pricing. ...
  • Buttery, B.S.; Burns, M.G.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Experiments have shown human chorionic gonadotropin (hCG) to be more effective than gondadotropin releasing hormone (GnRH) as a means to ovulate follicles. Experiment 1 determined the effects of replacing the ...
  • Corbeil, L.B.; Watt, B.; Corbeil, R.R.; Betzen, T.G.; Brownson, R.K.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1984)
    Immunoglobulin (Ig) concentrations in serurn and in nasal secretions were correlated with pneumonia and diarrhea during the first 12 wk of life of dairy calves. The peak onset of pneumonia occurred between 2 and 4 wk of ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1985)
    Profit or loss in the dairy enterprise is dependent upon yearly production per cow and degree of capitalization. Higher producing cows convert feed into milk more efficiently. Cows of similar body size have similar ...
  • Strahm, T.; Harner, Joseph P.; Murphy, James P.; McCormack, G.; Smith, J.F.; Key, David V. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Sixty four percent of the fields (14 of 22) in northeast and south central Kansas would be able to apply dairy manure on a nitrogen basis if the current swine manure application regulations were adopted. Due to high ...
  • Cvetkovic, B.; Shirley, John E.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Twenty-four lactating Holstein cows were used to determine the production response to the inclusion of brown seaweed in the basal diet during summer heat stress. Cows were blocked by lactation number, days in milk, and ...
  • Smith, John F.; Bradford, Barry J.; Harner, Joseph P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    A trial was conducted to determine the impact of evaporative cooling pads on core body temperature (CBT), time spent lying, and number of lying bouts of Holstein cows housed in cross-ventilated freestall facilities. ...
  • Smith, J.F.; Armstrong, D.V.; VanBaale, M. J.; Bray, D.R.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2005)
    Heat stress in hot and humid environments reduces milk production, decreases reproduction, and increases health-related problems. The summertime environment in north-central Florida is especially difficult because the ...
  • Dingwell, R.T.; Leslie, K.E.; Sargeant, J.M.; Schukken, Y.H.; Timms, L.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    A study of 250 cows located in Canada and the United States revealed the rate of new mammary infections was 9.9% during the dry period. Average milk production on the day prior to dry-off was 13.2 ± 7.2 kg. The odds ...
  • Harner, Joseph P.; Smith, J.F.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Separator efficiency and moisture content of separated solids influence the make-up water requirements on a dairy seeking to utilize recycled water for sand reclamation. Additional water requirements range from 0 to 79 ...
  • Harner, Joseph P.; Smith, J.F.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Manning’s equation provides a method to evaluate the flow characteristics of a flush plume system used to move a diluted, sandladen manure stream from a freestall building to sand or solid separation equipment. Evaluation ...
  • Armstrong, D.V.; Smith, J.F.; Wuthironarith, V,; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Ten multiparous lactating Holstein cows were arranged in a replicated 5 × 5 Latin Square design to evaluate the effect of soaking frequency and volume of water per soaking on lactating cows housed in a tunnel-ventilated and ...
  • Bradford, Barry J.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Supplemental phosphorus (P) in various forms and sources (pellet, meal, liquid, and corn dried distillers grains with solubles; DDGS) were compared in 12 multiparous Holstein cows producing 94.8 lb of milk (115 ± 55 days ...
