  • Call, Edward P. (Kansas Agricultural Experiment Station, 2011-05-12)
    An analysis of 4,334 Holstein dairies confirms the negative genetic correlation that exists between milk production and reproduction. The most obvious traits affected are services per conception and conception rate. When ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 2012-09-07)
    A computer program was developed for analyzing DHI records to evaluate potential losses from 1) reproduction, 2) nutrition, 3) milk quality, and 4) genetics. Production-tested Kansas Holstein herds were grouped according ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 2012-10-04)
    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 ...
  • Call, Edward P. (Kansas Agricultural Experiment Station, 2012-09-20)
    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 ...
