Conception Rates. 2. Economic Value of Unit Differences In Percentages of Sire Conception Rates

Journal of Dairy Science, 1994
The objectives of this research were to estimate 1) the annual increase in profitability and 2) the value of a unit of semen because of an increase of 1 in percentage of AI conception rate. Factors contributing to increased annual profit per cow included more milk production, less semen purchased, more calvings, and fewer reproductive cullings.

Estrous Intensity and Conception Rates in Holsteins

Journal of Dairy Science, 1983
During 34 mo, 732 inseminations were evaluated in Holstein cows and heifers of breeding age. Females were submitted for insemination after detection of either 1) standing estrus, 2) mounting activity, or 3) other subtle symptoms of estrus (clear mucus, general appearance of genitalia or tailhead, and excessive vocalization).
