  • Silage additive update: 1985
    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 ...
  • Silage Management: important practices often overlooked
    Bolsen, K.K.; Brent, B.E.; Siefers, M.K.; Uriarte, M.E.; Schmidt, T.E.; Pope, R.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.
  • Small intestinal starch, dextrin, and glucose digestion in steers

    Three Holstein steers (930 lb) were surgically fitted with abomasal and ileal cannulae, portal and mesenteric venous catheters, and an elevated carotid artery and used to study small intestinal starch digestion. Water, ...
  • Small-sized milk processing plant considerations
    Rosario, B. Macias; McVay, L.; Aramouni, F.; Schmidt, K.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Milk is widely considered one of the world’s most valuable foods. As a raw material, it is available in various forms, and is found in an ever-increasing variety of nutritional products. Milk is a complex biological fluid ...
  • Somatic cell count inversely related to potential profits in dairying
    Dunham, J.R. (Kansas Agricultural Experiment Station, 1992)
    Somatic Cell Count (SCC) affects productivity of a dairy herd and, thus, potential profit. Almost all SCC problems can be solved by management. The DHIA SCC program is very useful for evaluating the situation in a ...
  • Sorghum grain for lactating dairy cows
    Gladamez, C.A.; Shirley, J.E.; Gallegos, A.J. (Kansas Agricultural Experiment Station, 1990)
    Holstein cows in early lactation were utilized to evaluate the effects of supplementing concentrate diets of sorghum grain on milk production, milk composition, somatic cell count, and body condition. At 21 d postpartum, ...
  • Soybean products as a protein source in milk replacers for calves
    Dawson, D.P.; Morrill, J.L.; Reddy, P.G.; Minocha, H.C. (Kansas Agricultural Experiment Station, 1986)
    Studies were conducted to evaluate two comrnercl.al soy products and one experimental soy flour as protein sources in calf milk-replacers. Further tests were conducted to produce an improved product. None of the products ...
  • Stage of lactation profile reflects nutrition and management
    Dunham, J.R. (Kansas Agricultural Experiment Station, 1994)
    The Stage of Lactation Profile (SOLP) is a good estimate of the shape of the lactation curve for dairy herds. The SOLPs for herds with various milk production levels are somewhat similar. The rates of decline of ...
  • Strategies for small dairy farmers to be profitable and competitive in the future
    Cropp, B. (Kansas Agricultural Experiment Station, 1994)
    Profitable dairying will not become any easier in the future. Farm level milk prices will continue to be volatile. The government will not provide additional price or income support to dairies. Long-run milk prices ...
  • Success of several programed AI-breeding protocols including ovsynch
    Stevenson, J.S.; Thompson, K.E.; Kobayashi, Y. (Kansas Agricultural Experiment Station, 1996)
    In Experiment 1, four programmed AIbreeding treatments were tested. The so-called OvSynch program, which requires no heat detection before a fixed-time insemination, decreased conception rates compared with a similar ...
  • Supplemental progesterone increases pregnancy rates and embryo survival in lactating dairy cows
    El-Zarkouny, S. Z.; Cartmill, J. A.; Stevenson, J. S. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Administering progesterone to lactating dairy cows has sometimes proven effective in increasing pregnancy rates. In this study, cows were treated with the Ovsynch protocol in addition to supplemental progesterone given ...
  • Synchronization of estrus and ovulation in dairy heifers using norgestomet, GnRH, and PGF[subscript]2alpha
    Stevenson, J. S.; Thompson, K. E.; Smith, J. F.; Hawkins, D. E. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Two experiments were performed using the same treatments. All heifers received two injections of PGF[subscript]2alpha 14 days apart. Controls then were inseminated after detected estrus. Heifers assigned to the two ...
  • Synchronized ovulation with gonadotropin-releasing hormone, prostaglandin F and fixed-time insemination
    Stevenson, J.S.; Kobayashi, Y. (Kansas Agricultural Experiment Station, 1995)
    Summary Lactating Holstein cows and replacement heifers were treated with a novel synchronized ovulation protocol, which involves one fixedtime insemination without heat detection. One injection of GnRH (Cystorelin®) ...
  • Temperature changes in a low-profile, cross-ventilated building in the high plains
    Harner, J.P.; Smith, J.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Performance of an evaporative cooling system was evaluated in the High Plains in a low-profile, cross-ventilated dairy facility housing 4,200 lactating cows. The temperature decrease across the 6-inch cellulose evaporative ...
  • Times artifical insemination conception rates in response to a progesterone insert in lactating dairy cows
    Martel, C.A; Buttery, B.S.; Burns, M.G.; Brown, W.E.; Stevenson, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Our objective was to determine the effectiveness of exogenous progesterone in the form of an intravaginal insert (controlled internal drug release, CIDR) in conjunction with an ovulation synchronization protocol in lactating ...
  • Timing of parturition in dairy cattle
    Stevenson, J.S. (Kansas Agricultural Experiment Station, 1988)
