  • Smith, J.F.; Grigsby, K.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Forty lactating Holstein cows were allocated into groups of 5 cows each and assigned to 8 pens containing 10 freestalls each. Each group contained 3 heifers and 2 multiparous cows. Groups were balanced by milk production ...
  • Harner, Joseph P.; Smith, J.F.; Miller, W.F.; Cvetkovic, B.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Lactating dairy cattle were used to evaluate three different cooling systems. Eight cows were arranged in a replicated Latinsquare design and assigned to each of four treatments. Treatments were control, lowpressure soaking ...
  • Portaluppi, M.A.; Tenhouse, D.E.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Our objectives were to determine various factors influencing upfront single and multiple ovulation in response to GnRH in a timed arti-ficial insemination (TAI) protocol and subse-quent fertility after altering timing of ...
  • Martel, C.A.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Lactating dairy cows and replacement virgin heifers of unknown pregnancy status were treated with either gonadotropin-releasing hormone (GnRH) or saline to initiate a resynchronization program that was continued 7 days ...
  • Tiffany, S.M.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    We compared outcomes of two protocols used to resynchronize estrus and ovulation in dairy females after found open at pregnancy checks. Replacement heifers and lactating cows in which AI occurred 41 ± 1 day earlier ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1986)
    Recent developments in dairy cattle nutrition have resulted in the marketing of a calcium salt of isobutyric and mixed 5-carbon volatile fatty acids (IsoPlus®). The FDA approved product has been neutralized with calcium ...
  • Kube, J.C.; Frey, R.A.; Shirley, John E. (Kansas Agricultural Experiment Station, 1987)
    Two Holstein cows were fed Rumensin for 12 weeks, beginning approximately 90 days postpartum. Milk production increased 7%, whereas percentage fat in milk decreased 10.3%. Percentage protein in milk increased 9.6% in ...
  • Nagaraja, T. G.; Katz, M.P.; Fina, L.R. (Kansas Agricultural Experiment Station, 1985)
    Monensin at 300 mg and 450 mg per 1000 lbs body weight reduced the severity of alfalfa pasture bloat by 41.2 and 73.1 %, respectively. Lasalocid at the same levels reduced the bloat score by 25.5 and 12.4%. The difference ...
  • Wessels, R.H.; Titgemeyer, Evan C.; St. Jean, G. (Kansas Agricultural Experiment Station, 1994)
    A trial was conducted to investigate the effect of lasalocid (Bovatec®) on ruminal degradation of dietary protein in Holstein steers. Five ruminally and duodenally cannulated steers (305 kg) were fed a corn-alfalfaso ...
  • Anderson, K.L.; Nagaraja, T. G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    Accelerating the weaning age of calves appeared to increase their ruminal metabolic activity. This was indicated by the lower ruminal pH and increased, total volatile fatty acid concentration of calves weaned at 4 wk of ...
  • Schmidt, D.G.; Gnad, D.P.; Sargeant, J.M.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Salmonella dublin is a bacterium that can have devastating effects in dairy herds. It is most deadly with calves that range in age from 10 days to 5 months. Salmonella dublin is shed from carrier animals through feces, ...
  • Park, A.F.; Smith, J.F.; Rozell, Timothy G.; Stevenson, Jeffrey S.; Shirley, John E.; Scheffel, Michael V. (Kansas Agricultural Experiment Station and Cooperative Extension Service., 1998)
    Representative MUN values can be obtained by testing a milk sample before milking, at AM or PM milking, or with an in-line siphon sampling device. MUN values obtained from homogenous milking strings are as accurate ...
  • Hollis, Larry C.; Smith, J.F.; Johnson, B.J; Kapil, S.; Mosier, Derek A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2005)
    One hundred and four, 5- to 10-month-old Holstein heifers and steers were blocked by age within gender and randomly assigned to treatments. Calves were vaccinated with 5- way modified-live respiratory viral ...
  • Francis, L.L.; Kong, S.H.; Chambers, Delores H.; Jeon, I.J.; Simmons, S.R.; Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Many people seem to prefer to drink milk when it is cold. Research describing flavor and aftertaste of milk, and then correlating these traits with their chemical composition, has not previously been done. The ...
  • Dryden, Michael W.; Broce, A. B. (Kansas Agricultural Experiment Station, 1991)
    In June 1991, an investigation was conducted of a severe flea infestation in 23 Holstein dairy calves in South Central Kansas. Inspection of the dairy revealed massive numbers of fleas on calves and in the barn where ...
  • Bolsen, K.K.; Hoover, J.D. (Kansas Agricultural Experiment Station, 1985)
    Silage additives are receiving fairly widespread acceptance in the U.S. as management tools that are important for silage-making. Many products, which are added to the crop at the time of harvest or ensiling, are available ...
  • Bolsen, K.K.; Brent, B.E.; Siefers, M.K.; Uriarte, M.E.; Schmidt, T.E.; Pope, Ronald V. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Four important silage management practices that are in the control of livestock producers and that are sometimes poorly implemented or overlooked entirely include: inoculating, packing, sealing, and managing the feedout face.
  • Kreikmeier, K.K.; Harmon, D.L.; Avery, T.B.; Brandt, Robert T., Jr. (Kansas Agricultural Experiment Station, 1988)
