  • Smith, J.F.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Recently, there has been interest in constructing mechanical ventilation with evaporative pads to improve the environmental conditions for cows during periods of heat stress. Low profile cross-ventilated freestalls with ...
  • Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Accelerated-growth feeding programs are the newest buzz word in calf rearing. Accelerated programs require a milk replacer containing more crude protein and less fat content than traditional milk replacers. These ...
  • Stevenson, Jeffrey S.; Mee, M. O.; Call, Edward P. (Kansas Agricultural Experiment Station, 1991)
    Administering saline to 14 repeat breeders or 100 μg GnRH to 38 repeat breeders resulted in a greater (P=.07) proportion of pregnancies at 42 to 56 days after third service and fewer (P<.05) lost pregnancies during the ...
  • Ikins, W.G. (Kansas Agricultural Experiment Station, 1986)
    Aflatoxins are toxic compounds that are produced by certain strains of molds, namely, Aspergillus flavus and Aspergillus parasiticus. These molds may invade stressed crops in the field or proliferate in improperly stored ...
  • Phebus, Randall K. (Kansas Agricultural Experiment Station, 1993)
    Mycotoxins are toxic chemicals produced by certain species of molds during their growth on numerous substrates. Molds can invade the food and feed supply at various points throughout production, storage, processing, ...
  • Mullins, C.R.; Grigsby, K.N.; Bradford, Barry J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    In this experiment, we evaluated the effects of varying alfalfa inclusion rate in diets containing 31% wet corn gluten feed on a dry matter basis. Eighty lactating Holstein cows were allocated into groups of 10 and ...
  • Cartmill, J.A.; Zarkouny, S.E.; Hensley; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    The incidence of anestrus in dairy cattle prior to first inseminations carried out after a minimum of 60 days postpartum ranged from 4 to 58% in first-lactation cows and 14 to 50% in older cows. Dairy cows with more days ...
  • Wilson, R.W. (Kansas Agricultural Experiment Station, 1988)
    The makers of the laws, rules, and regulations governing the production and processing of milk have recognized that milk is the primary diet of the very young and old. This fact mandates that it should be produced and ...
  • Sargeant, J.M.; Gnad, D.P.; Isch, J.; Bathina, H.; Lising, J.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    A field trial was conducted to compare oxytetracycline to three nonantibiotic therapies using bandage protocols for the treatment of hairy heel warts. Affected feet were bandaged for 4 days with either of the four products. ...
  • Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Use of progesterone inserts (controlled interval drug release, CIDR) offers another option for synchronizing estrus and ovulation in replacement heifers and lactating dairy cows. Results indicate that heifers may be ...
  • Dingwell, R.T.; Leslie, K.E.; Sargeant, J.M.; Schukken, Y.H.; Timms, L.L.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Data from 300 cows and 1,178 quarters were analyzed to determine factors associated with new intramammary infections (IMI). Teatends that were cracked and teats that did not close during the dry period were 1.7 and ...
  • Jeon, I.J. (Kansas Agricultural Experiment Station, 1986)
    In 1985 the annual sales of dairy products on the average grew 3.3%, and is expected to grow 6.4% in 1986, according to the U.S. Department of Commerce. This positive growth was attributed in part to increased consumer ...
  • Zimmerman, S.; Jeon, I.J.; McVay, L.; Ferdinand, E.; Sukup, D.; Shirley, John E.; Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Raw milk is an excellent medium for bacterial growth. The objective of this study was to evaluate the number of microbes and component degradation in raw milk. Milk fat content did not affect bacteria counts. As storage ...
  • Banala, S.; Brouk, Michael J.; Simmons, S.R.; Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Various percentages (1.2% to 13%) of β- cyclodextrin (β–CD) were added to water or pasteurized whole milk to study β-CD crystallization patterns. Influential factors such as crystallization time (4 to 12 h), ...
  • Harbers, L.H.; Ward, G.M.; Dayton, A.D. (Kansas Agricultural Experiment Station, 1984)
    The availability of oxalate and non-oxalate calcium in alfalfa was determined using a chick assay. Oxalate-bound calcium was found to contribute only 16% as much influence as nonoxalate calcium. The nonoxalate calcium ...
  • Elwakeel, E.A.; Titgemeyer, Evan C.; Brake, D.W.; Nour, A.M.; Nassar, M.E.; Faris, Brian R. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2010)
    Twelve mature sheep were used as a ruminant model to estimate the bioavailability of lysine in hydroxymethyl lysine (HML) compared with a commercial product of rumen-protected lysine (RPL; LysiPEARL, Kemin Industries, ...
  • Stokka, Gerald L.; Falkner, Thomas R.; Bierman, Patrick (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Three strategies exist to control unwanted disease in a livestock operation: 1) prevent the douintroduction of infected cattle, 2) raise the overall level of resistance and specific resistance to infectious disease, and ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1993)
    Body condition scoring provides a tool to help the dairy herd manager evaluate his/her nutrition and management program. It takes time, has an associated cost, and will result in a positive economic return if one makes ...
