  • Daccarett, M. G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1989)
    One hundred and one Holstein heifers from the KSU Dairy Unit were used in this experiment. They were assigned to two treatments in which they were fed either 100% or 115% of the 1988 NRC requirements of energy, protein, ...
  • 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 ...
  • 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 ...
  • Isbell, D.E.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1990)
    Sixty heifer and 34 bull calves were fed starter diets containing either control or extruded soybean meal (SBM) and either 2.5% or no bypass fat from birth to 8 wk of age. There were no interactions between the type of ...
  • Anderson, K.L.; Nagaraja, T. G.; Morrill, J.L.; Reddy, P.G.; Avery, T.B.; Anderson, N.V. (Kansas Agricultural Experiment Station, 1987)
    Twenty newborn bull calves assigned to two groups, protozoa-free or protozoa-inoculated, were used to determine the effects of ruminal protozoa on performance of early weaned calves. Calves in the protozoa group were ...
  • Beharka, A. A.; Nagaraja, T. G. (Kansas Agricultural Experiment Station, 1991)
    The effect of Amaferm on growth of pure cultures of ruminal cellulose-digesting, hemicellulose- digesting and pectin-digesting bacteria was determined. The addition of Amaferm to the growth medium increased the growth ...
  • Hollis, Larry C.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Objectives of this study were to investigate the possible effects of heat stress on calf growth and the development of active immunity. Eighteen heifer calves born between July 21 and August 24, 2008, were housed in ...
  • Hammond, A.; Scheffel, Michael V.; Titgemeyer, Evan C.; Stevenson, Jeffrey S.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    One hundred and twenty Holstein heifers weighing approximately 450 lb at the beginning of the study were used to evaluate the impact of bambermycins (Gainpro®), monensin (Rumensin®), and lasalocid (Bovatec®) on performance ...
  • Velazco, J.; Morrill, J. L.; Brandt, Robert T., Jr.; Schalles, R. (Kansas Agricultural Experiment Station, 1991)
    Sixty-four Holstein steers were used to study the effect of season and age on performance. Animals beginning the trial in spring were heavier (P<.05) and more efficient than calves started in other seasons. There were ...
  • Morrill, J.L. (Kansas Agricultural Experiment Station, 1994)
    On many dairy farms, improvement is needed in raising replacement heifers, especially in providing proper nutrition and management to allow for freshening at 23 to 24 mo of age at a desirable size. With larger herds, there ...
  • Meyer, M. J.; Everett, R.W.; Van Amburgh, M.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    The primary advantages of reducing age at first calving (AFC) include reducing rearing costs as well as reducing time in which the heifer is only a capital drain on farm resources. The primary disadvantage of reducing AFC ...
