  • Mee, M.O.; Stewart, R.E.; Stevenson, Jeffrey S.; Call, Edward P. (Kansas Agricultural Experiment Station, 1987)
    Progesterone administered before breeding may increase estrous expression and subsequent fertility in lactating dairy cows. Holstein cows (n=302) were assigned randomly at calving to three groups. Cows received no ...
  • Anderson, K.L.; Nagaraja, T. G.; Morrill, J.L.; Reddy, P.G.; Avery, T.B.; Anderson, N.V. (Kansas Agricultural Experiment Station, 1987)
    Twenty-two newborn, bull calves were used to determine the effects of lasalocid on growth and feed intake of early-weaned calves from week 1 to 12. Calves were assigned to lasalocid or control groups on day 3. Lasalocid-fed ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1987)
    The economic climate in the dairy industry requires producers to operate efficiently to remain competitive. Attention to details and understanding of reproduction, metabolism, digestive functions, milk secretion, and all ...
  • Shirley, John E.; Morrill, J.L.; Carinder, W.H. (Kansas Agricultural Experiment Station, 1987)
    Soybeans interseeded with grain sorghum and harvested as a mixed forage silage crop can be used successfully as a feed for growing dairy heifers. However, daily gain is greater when grain sorghum silage plus alfalfa hay ...
  • Kube, J.C.; Frey, R.A.; Shirley, John E. (Kansas Agricultural Experiment Station, 1987)
    Two Holstein cows were fed Rumensin for 12 weeks, beginning approximately 90 days postpartum. Milk production increased 7%, whereas percentage fat in milk decreased 10.3%. Percentage protein in milk increased 9.6% in ...
  • Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1987)
    In three of six studies involving over 1,650 cows, treatment of lactating dairy cows with 100 µg GnRH (2 cc Cystorelin®) at the time of third or fourth insemination improved conception rates by 12 percentage points. When ...
  • Stevenson, Jeffrey S.; Call, Edward P. (Kansas Agricultural Experiment Station, 1987)
    Poor heat detection is a major cause of reproductive failure in most dairy herds. About one-half of the heat periods are undetected, resulting in prolonged calving intervals. In many cases, the problem is serious enough ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 1987)
    USDA-DHIA Sire Summaries are published semiannually and provide the dairy industry with an accurate evaluation of the transmitting ability of bulls for milk and milk components. Genetic potential is established at the ...
  • Dawson, D.P.; Morrill, J.L.; Reddy, P.G.; Behnke, Keith C. (Kansas Agricultural Experiment Station, 1987)
    Oil-extracted, desolveritized soy flour without additional heat treatment was used to prepare protein supplements for calf milk replacers by extrusion processing. Various combinations of temperature, moisture, calcium ...
