  • Dunham, James R. (Kansas Agricultural Experiment Station, 1987)
    Cows and heifers in milk for fewer than 50 days, as shown on the DHIA Somatic Cell Count report, should have a lower average Somatic Cell Count than cows in milk for more than 300 days, if the dry cow mastitis treatment ...
  • Stevenson, Jeffrey S.; BenMrad, M. (Kansas Agricultural Experiment Station, 1985)
    A study of 234 Holstein cows was conducted to determine if hormonal treatments of gonadotropin-releasing hormone (GnRH or Cystorelin®) and(or) prostaglandin F2a (PGF or Lutalyse®) given early after calving would ...
  • Mee, M.O.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1988)
    Progestin (Norgestomet®) and(or) repeated low-dose infusions of GnRH (Cystorelin@) influenced the lifespan of the first corpus luteum after an induced ovulation. Holstein cows (n=32) were assigned at calving to four ...
  • Dhuyvetter, Kevin C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    The economic impact of cooling cows to reduce the seasonal variation in peak milk production was estimated using researchbased lactation curves and peak production numbers for a commercial dairy operation in Kansas. ...
  • Smith, J.F. (Kansas Agricultural Experiment Station, 1995)
    As new technologies such as rbST become available to dairy producers, evaluating the profitability of those technologies on individual farms is essential. Costs associated with rbST include purchase of product, feed, ...
  • Shirley, John E.; Miller, W.F.; Rottinghaus, J.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Five hundred and thirty Holstein cows located in a commercial dairy herd near Birdseye, Indiana, were used to evaluate an iodophor (0.50% iodine) teat dip containing a new conditioner. The new teat dip (Dinerin) ...
  • Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Yogurt was manufactured by pre-acidifying the yogurt mix with citric acid, lactic acid, or concentrated lemon juice either before or after pasteurization to a target pH of 6.2, and then the traditional manufacturing process ...
  • Jordan, K.J.; Morrill, J.L.; Reddy, P.G.; Higgins, James J. (Kansas Agricultural Experiment Station, 1985)
    Previous work at the Kansas Agricultural Experiment Station contributed to the development of an early weaning program (see 1984 Dairy Day, Report of Progress 460). This program involves the use of a prestarter, which ...
  • Jordan, K.J.; Morrill, J.L.; Reddy, P.G.; Higgins, James J.; Anderson, N.V. (Kansas Agricultural Experiment Station, 1986)
    Potassium chloride added to the prestarter and/or potassium bicarbonate added to the starter fed to early weaned calves helped maintain normal blood alkalinity and normal levels of blood gases, and resulted in a trend ...
  • Morrill, J.L.; Reddy, P.G.; Behnke, Keith C.; Higgins, James J. (Kansas Agricultural Experiment Station, 1985)
    Three starters containing differently processed protein supplements were fed to Holstein heifer calves, using an early weaning program. One starter contained soybean meal. The other starters contained soybean grits ...
  • Smith, J.F.; Harner, Joseph P.; DeFrain, S.E.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Heat stress reduces milk production, feed intake, and reproductive efficiency each summer in Kansas. Without heat abatement procedures, milk production may decline 20- 30% during the summer months. Research has shown ...
  • Smtih, J.F.; Harner, Joseph P.; DeFrain, S.E.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Cows previously trained with headlocks did not increase milk production or feed intake when headlocks were removed. Twoyear- old and older cows did not differ in response to headlocks and neckrails. Prudent use of ...
  • Isbell, D.E.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1989)
    Sixty-four Holstein heifer calves were used from 10 to 26 wk of age to study the effects of lasalocid on growth and feed consumption. Calves were evaluated weekly for weight gain and feed consumption. Lasalocid-fed heifers ...
  • Whitlock, L.A.; Siefers, M.K.; Pope, Ronald V.; Brent, B.E.; Bolsenn, K.K. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Twelve ruminally cannulated crossbred steers were used to determine the effect of level of surface spoilage in corn silage-based rations on dry matter (DM) intake and nutrient digestibilities. Irrigated corn was ...
  • Flynn, P.; Reddy, P.G.; Morrill, J.L.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1986)
    Feeding milk at 8% of birthweight and gradual weaning resulted in the most consistent increases in weekly weight gain, highest overall weight gain, and greatest increases in dry feed consumption during an 8-wk trial ...
  • Laytimi, A.; Grimes, C.; Bolsen, K.K. (Kansas Agricultural Experiment Station, 1985)
    Third cutting alfalfa was baled in large I-ton rectangular bales and in small conventional bales at three moisture levels, low (10%), medium (16%), and high (22%). During 120 days of storage under a roof, the high-moisture, ...
  • Dufva, G.; Bartley, E.; Dayton, A.; Riddell, D. (Kansas Agricultural Experiment Station, 1984)
    Two lactation trials were undertaken to evaluate the effect of a niacin supplement on milk production and 'the physiological symptoms of ketosis. Blood ketone and non-esterified fatty acid levels were lower and blood ...
  • Isbell, D.E.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1989)
    One hundred and twelve Holstein heifers were used from 10 wk until 26 wk of age. They were assigned to receive either 100% or 115% of NRC (1978) recommended nutrients and to be fed either control or extruded SBM. There ...
  • Estrada, J.M.; Shirley, John E. (Kansas Agricultural Experiment Station, 1990)
    Summary Blood samples were collected from 16 Holstein cows around parturition to obtain baseline values of various hormones and metabolites. At 90 ± 3 days postcalving, cows were divided into two groups (8 cows/group) ...
  • Beharka, A.A.; Nagaraja, T. G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1990)
