  • Reddy, P.G.; Morrill, J.L.; Minocha, H.C.; Frey, R.A.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1986)
    Thirty-two Holstein heifer calves receiving conventional rations were supplemented with 0 (control), 125, 250, or 500 IU vitamin E/calf/day. The objective was to determine the optimum requirement based on their ...
  • Heikes, K.A. (Kansas Agricultural Experiment Station, 1986)
    For maximal genetic progress in a dairy, proven AI sires should be selected to use on replacement heifers. To minimize problems at calving, these sires should be selected from bulls that are breed average or better for ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Avery, T.B. (Kansas Agricultural Experiment Station, 1986)
    Common disease causing agents are identified and a sample replacement heifer health program is presented. Written objectives are useful for evaluation of heifer rearing.
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1986)
    Records are the backbone of any breeding program. Artificial insemination (AI) is essential to maximizing genetic gain and minimizing calving problems and breeding costs. In addition, AI allows controlled calving - calving ...
  • Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    For many years, fiber in dairy rations was measured and expressed as crude fiber. More recently acid detergent fiber (ADF) and neutral detergent fiber (NDF) have been used. The crude fiber (CF) determination uses acid ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1986)
    The present surplus of dairy products has led to a decrease in farm-level milk receipts. Future reductions in the federal milk price support program, together with a predictable increase in feed grain and protein supplement ...
  • Stevenson, Jeffrey S.; Call, Edward P. (Kansas Agricultural Experiment Station, 1986)
    Diagnosing pregnancy in dairy cattle is an essential part of good management. The objective of this procedure is not to identify pregnant cows, but to identify the nonpregnant cows, those that become the breeding ...
  • Roberts, H.A. (Kansas Agricultural Experiment Station, 1986)
    Milk consumption is influenced by the quality and flavor of the milk a person drinks. Today the consumer evaluates milk solely on its taste and keeping quality. Since the flavor of milk cannot be improved after it leaves ...
  • Kube, J.C.; Shirley, John E.; Frantz, K.D. (Kansas Agricultural Experiment Station, 1986)
    Springing heifers and dry cows were introduced to a computer feeder either 2 wk before their estimated freshening date or at calving. There was no significant difference in milk production, percentage milk fat, percentage ...
  • Kube, J.C.; Shirley, John E.; Frantz, K.D.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1986)
    Lactating dairy cows were introduced to a computer feeder in early (≤120 days in milk or D.I.M.), mid (120-220 D.I.M.), and late (>220 D.I.M.) lactation. Cows in the mid- and late-lactation groups adjusted quicker and ...
  • Stewart, R.E.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1986)
    Release of oxytocin at the time of suckling or milking may delay onset of estrous cycles in postpartum cows. Twenty lactating Holsteins were used in this study to determine if multiple daily injections of oxytocin would ...
  • Harbers, L.H. (Kansas Agricultural Experiment Station, 1986)
    It has been over 15 years since an analytical instrument was developed that could rapidly determine the concentration of organic compounds from the spectra produced by the bonding between carbon and certain molecules. ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1986)
    Prostaglandin F2α (PGF) and gonadotropin-releasing hormone (GnRH) have provided new dimensions in resolving certain reproductive maladies. Effective when used properly, these hormones have the advantage of mimicking the ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1986)
    Feed additives are ration ingredients used in relatively small amounts to fortify certain nutrients or to affect a specific physiological function. The decision to include any additive should be based upon the economic ...
  • Carinder, W.H.; Reddy, P.G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    An experimental calf-starter diet containing roasted whole soybeans, buffer and dehydrated alfalfa pellets was compared with a conventional calf starter for young calves on an early-weaning program. Overall means for ...
  • Miller, G.W.; Nagaraja, T. G. (Kansas Agricultural Experiment Station, 1986)
    The effect of diet on in vitro lactic acid utilization rate and counts of lactic add-utilizing bacteria was determined in ruminally cannulated steers. The steers were adapted to an alfalfa diet and gradually switched to ...
  • 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 ...
